Dipus (Gme:) or Gerboise D. Class. [listed as Mus elegans in Mammalia: 41-2]

This little animal does not appear to agree exactly with any of the subgenera of Cuvier. It was caught Octob^r 3 at Monte Hermosa in B. Blanca. In bringing at night a bush for fire wood, it ran out with its tail singed. So probably it inhabits bushes; it could not run very fast; it is a male; after skinning the head, it has a much more elongated appearance than it had in nature: Inhabits sand-dunes.

Cervus (campestris?) also (1292) — [listed as Cervus campestris in Mammalia: 29-31]

These animals deer are exceedingly abundant over throughout all the countries bordering the Plata; they extend are found in Northern Patagonia as far South as the R. Negro (Lat. 41^o); but further southwards than which they were never seen by the officers employed on the coast survey. — They appear to prefer a hilly country. — I saw them most numerous in great numbers, around the Sierra Ventana & amongst the hills north of Maldonado. — They generally go in small herds from five to seven in number. — If a person approaches a herd crawling close along the ground slowly advances, the deer will frequently out of curiosity, approach to reconnoitre him. — I have, by this means, killed from one spot three out of the same herd. — Although thus so tame & inquisitive, yet when approached on horseback they are exceedingly wary. In this country nobody goes on foot; & the deer only knows man as his enemy when mounted & armed with the Bolas . — (a) The Gauchos say that the deers shed their horns annually, & that by the number of branches they can distinguish their age.

affirm to be nine years old. Certainly its teeth were in a most decayed state. Another & younger Buck had horns (1337 & 1338). D The most curious fact with respect to this animal is the overpoweringly strong & offensive odour which proceeds from its whole the body of the buck. — It is quite indescribable. Several times whilst skinning the Specimen (1292), which is now mounted at the Zoological Society Museum, I was almost overcome by nausea. — I tied up the skin in a silk pocket-handkerchief, & so carried it home. This handkerchief, after being well washed, I continually used; & it was, of course, as repeatedly washed. Yet, every time, when first opening it unfolded, for a space of two one year and seven months, I distinctly perceived the odour. (a) — Is not this an astonishing instance of the permanence of some matter, which nevertheless in its nature must be most subtle & volatile. Frequently when passing at the distance of half a mile to Leeward of a herd, I have perceived the whole air tainted with the effluvium. I believe the smell from the buck is most powerful at the period when its horns are perfect or free from the hairy skin. When in this state the meat is of course quite uneatable; but the Gauchos assert that if buried for some time in fresh earth, the taint will be removed. — I have read in some work that the Islanders to the north of Scotland, treat in the same manner the rank carcases of the fish-eating birds.

plains composed of arid gravel or sand, & bearing a withered vegetation & few spiny bushes, it is a common feature in the landscape to see, in the distance, two or three of the Agouti quickly hopping, after each other, in a straight line. I have never heard of this animal being found S. of Lat. 48^o 30' (between P. Desire & St Julians); & to the Northward, the Sierra of Tapalguen (Lat. 37^o 30') is its limit. This however must depend on the country, northward of those hills being more humid & clothed with green pasture: Hence in the Traversia, or desert, a few leagues S. of Mendoza (33^o—34^o) I again saw it. — Azz ara has stated (Griff: An: King:) that the Agouti does not excavate its own burrows, but uses those of the Biscatches. As, in the case of the little owl, where such are present, this without doubt happens; — but on the sandy plains of Bahia Blanca, the Biscatche is not found; and the Gauchos there maintain that the Agouti, when thus situated, certainly is its own workman. — R Azz ara also says that the Agouti, excepting when pressed by danger, does not enter the its burrows. — On this point I must again differ from that high authority. At B. Blanca I have repeatedly seen two or three of these animals, sitting on their haunches, by the mouths of the holes, & as I passed by at a distance, they would quietly enter them. — The burrows are excavated on any flat, solid piece of land; several of them are placed together so as to make a very small warren. —

the Agouti were abundant. But differently from most burrowing animals it wanders, commonly by two or three together, to miles or leagues from its home. Nor do I know whether it returns at night. — The Agouti feeds & roams about by day; is shy & watchful; does not squat (or so rarely that I never saw an instance); cannot run very fast; so that it is frequently overtaken by two fleet dogs of mixed breed. Its manner of running more resembles that of a rabbit than a Hare, it consists of distinct springs. — The Agouti generally produces two young ones at a birth, which are brought forth within the burrow (I am told). Their dung is of an elongated oval form & large for size of animal. — A fresh-killed animal generally weighs from 20 to 25 pounds. — The flesh when cooked is very white; it is however rather tasteless & dry. — R

Cavia cobaya. Is exceedingly abundant in the neighbourhood of Maldonado (where this specimen was shot) & around the city of B. Ayres. Is called Aperea. — It frequents localities of different natures: sand dunes, the bottom of the hedge rows made of the Agave or Cactus, & especially marshy places covered with aquatic plants. On gloomy days & in the evening they come out to feed; are not very timid & can easily be shot. In dry places, they have burrows; but in the swamps, from the soft state of the mud, this is impossible. — They are said to be very injurious to young trees in gardens. — An old male weighed 1 £b, 3 oz.

of Indians in those parts take their name from this animal. At the Rio Negro the Spaniards called it el "Conejos" or the rabbit. Hence arises the mistake of M. Lesson in believing that Magellan saw his Lepus magellicanus (black rabbit of the Falkland's) in the St. of Magellan. —

Tuco-tuco. — This curious animal is abundant throughout in the country of Maldonado; but is difficult to be procured & still more difficult to be seen when at liberty. — It lives almost entirely under ground; & prefers a sandy soil with a gentle inclination, as for instance, where the sand dunes of the coast join on to the grassy plains of the interior. But they are likewise found in other situations, & I have even seen them in a damp place near to a lake. The burrows are seldom open, they are said not to be deep, but of great length; at their mouths the earth is thrown up, but not quite into so large hillocks as by the Europæan Mole; the work is done generally during the night. — Considerable tracts of country are so completely undermined, that horses in passing over sink above their fetlocks. These animals tuco-tuco appears to be to a certain degree to be gregarious: the man who procured the specimens for me had caught six together, & he asserted that this was a common circumstance occurrence. It is said also that they come out at night to feed; that they do come out is certain, for I have seen their tracks; but I must think their principal food is afforded by the roots of plants; it is the only way of accounting for their extensive & superficial burrows. — In the stomach

of one, which I opened, I could only distinguish, amidst a yellowish green soft mass a few vegetable fibres. (a) This animal is in the country universally known by a very peculiar noise, which it makes beneath the ground. — A person, the first time of hearing it, is much surprised, for it is not easy to tell whence it comes, & it is impossible to guess what kind of creature utters it. — The noise consists in a short, nasal, (but not rough) grunt, which is repeated about four times in quick succession; the first grunt is not so louder, but a little longer than, & more separated from, the three following — the musical time of the whole is constant one same & [illeg] as often, as it is uttered. The name Tūcŏ-tūcŏ is given in imitation of the sound. — At all times of the day, in the parts localities where this animal is frequent, the noise, sometimes directly beneath your one's feet, may be heard. — When kept in a room, the Tūcŏ-tūcŏs move both slowly & clumsily, this appears chiefly to arise from the outward action of their hind legs: they are quite incapable of jumping the smallest vertical height. Their teeth (of a bright wax yellow & always never uncovered by the lips) are not adapted to gnaw holes or cut wood. — When eating biscuit, they rested on their hind legs & held the piece in the fore paws; they appeared also to wish to drag their food into some corner. — They are very stupid in making any attempt to escape; when angry or frightened, they uttered the Tūcŏ-tūcŏ. — Of those I kept alive, several were very exceedingly tame, they would not attempt to bite, or to run away.

A specimen 659, which I preserved in spirits would certainly appear to be in this state; having placed my finger within half an inch of its head, not the slightest notice was taken . of it.

August.

At the R. Negro (Lat 41^o) some animal frequenting  same sites & similar situations makes also the same kind of burrow, but its grunt or noise, although of the same class, is decidedly different from that of Maldonado. It is repeated only twice instead of three or four times, & it is more distinct, loud, & sonorous; it may be compared to the very distant sound of the blows of an axe, cutting down when a small tree is cut down; so close is this resemblance, that I have sometimes remained in doubt for a few minutes. —

At Bahia Blanca (Lat: 39^o) another (or the same) animal makes a similar noise, but repeated at single intervals, either at equal times or in an accelerating order. I was assured these animals are found of many different colours, and therefore I presume are of as many species. At B. Blanca, having caught a mouse (1284), many of the country people maintained that it was the Tuco-tuco, & the author of the noise. — What is the truth? Azara p.325 wonders how they travel 75 leagues. too much suppose. Crossing rivers more surprising Whatever the animal, or animals, may be, it or they must be excessively numerous; immense tracts of country, from the Rio Negro northward as far as the Sierra Guitru-Leique, are undermined so that the horses sink with every second or third step, fetlock deep. — At Cape Negro in the St. of Magellan, where Patagonia blends with T. del Fuego, the whole sandy country is forms one great warren for the Meldorado Tuco-tuco. They likewise occur S. of St. of Magellan. F — Head (1795) may perhaps be sufficient to ascertain specific resemblance or the contrary.

[8v]

(a): Considering the subterranean habits of the tuco-tuco, the frequent blindness, though so frequent, cannot be a very serious evil. Yet it appears odd that any animal should possess an organ constantly subject to injury.

It is The mole, whose habits are so similar in nearly every respect, excepting in the kind of food, has an extremely small protected eye, which although possessing a limited vision, seems at once adapted to its manner of life.

Rat. Was killed at the Is^d of Guritti (which forms Maldonado Bay). — They are there, & likewise on East point, very common. Inhabit burrows in the sand dunes. I should think, from its habits, it must be an aboriginal of the country, but if Ships are ever infested with such monsters, both the above spots are likely places for Colonies to be established. — The occurrence of these rats on the Is^d of Guritti need not be a difficulty, for it is connected with the mainland by a reef, which probably once was dry land. — The ears of this animal are whitish & oddly contrasted with the colour of the rest of body. — An old male weighed 15,¾ oz. — [listed as Mus (decumanus) maurus in Mammalia: 33]

Taturia hybrida. Killed, S. de Tapalquen, Lat. 37^o30'. — Besides this species I have seen three others, the T. Pichiz, T. villosa, & T. Apar. — These three frequent the arid sandy plains of Bahia Blanca, & do not appear to prefer any particular localities. — The T. Pichiz (which in the neighbourhood of Mendoza, & sometimes in other places, is called the Queriquincho) is excessively numerous & far more abundant than the other species. On the East side of America, it appears never to go to the North of the S. de Tapalquean (Lat. 37^o30'), which dividing two sorts of countries, terminates the range of many animals. It is very common on the sterile plains around the S. Ventana & on the banks of the R. Negro. — In central & S. Patagonia it is not abundant. I have a specimen from Port Desire (1697), & at the S. Cruz (Lat. 50^o) I saw its shell. (a) (Pichiz?) This probably is its Southern limit. In a day's ride on the plains of B. Blanca several may generally be met with; the sand dunes however near the coast appear a very favourite resort. — In these localities the Pichiz cannot taste water during several months together. It wanders about freely during the day; when disturbed, either tries to avoid detection by lying close to the ground, or commences burrowing quickly in the soft soil. So rapid is this process that if on horseback it is necessary to spring off in order to secure the animal by its hinder quarters. — The Pichiz, when roasted in its shell is very fat & excellently good eating. I have repeatedly opened the stomach of this animal, & have found in it Coleoptera & various Larvae, — also roots & an Amphisboena. It is said they produce two or three young ones at birth. — The T. villosa is called " Peludo" (or hairy). — The T. Apar is known by the name of Mataco. (B)

Animals

Neither of these species are found much further South than B. Blanca, but to the Northward I heard of them at St Jago (in Lat. 28^o). The Peludo is a nocturnal animal, & is caught by people going out at night with dogs. — This is the only species which is found in the vicinity of B. Ayres. — The fourth species, T. Hybrida, is called Mulita or Mulillo (little mule). I believe it is never found S. of the S. Tapalquen in 37^o30'; there they are abundant & are sent thence to B. Ayres. — This species appears to prefer hilly rocky ground; it & the Peludo are common in Banda Oriental & Entre Rios. — We have seen, then, that the Pichiz extends far Southward, & that its place to the N. is taken by the Mulita; the Peludo & Mataco encroach a little on the territory of the Pichiz. — This however only refers to the E. coast, for at Mendoza (33^o) the four species are found together.

The sterile plains at the foot of the Cordillera, elevated several thousand ft above the sea, appear the probable birthplace of nearly all the animals, Birds, & perhaps even plants of Patagonia.

Animals

the Cordillera, it occurs; & close by, within the mountains, the allied Alpine species is found. — It is a curious circumstance in the geographical distribution of this animal that although it has passed the R. Parana, & is common in the province of Entre Rios, yet it has never been seen in Banda Oriental, to the Eastward of the Uruguay. Yet in that province, plains occur which appear admirably adapted to its habits. — It must be believed that B. Oriental owes this great advantage to the broad barrier of the waters of the Uruguay. — Near to B. Ayres these Biscatche animals are exceedingly common; their most favourite resort appears to be those parts of the plain, which during one half the year, are covered with giant thistles to the exclusion of other vegetables. — The Gauchos affirm that it lives on roots; this, from the great strength of the grinding teeth & the kind of localities frequented, seems probable. — As in the case of the rabbit, a few holes are commonly placed together: in the evening the Biscatches come out in numbers, & then quietly sit on their haunches. They are, at such times, very tame, & a man on horseback passing by seems only to present an object for their grave contemplation. They do not appear to wander far from their burrows. They run very awkquardly, & when hurrying out of danger, from their elevated tails & short front legs, much resemble a great rat. — I have been informed on excellent authority that quasi canes, post coitum adnexi sunt. Their flesh when cooked is very white, & although scarcely ever used, is good food. — The Biscatche has one very singular habit; it is

[13v]

(a): I once saw this animal sitting on a lofty pinnacle (probably 8000 ft above sea) in the Pass of the Patillo. It inhabits alone very lofty places: I have seen it at a height of about 6000 ft. Lives under the stones; comes out in the evening, at which time & during the early part of the night utters a low whistle. — In this respect differs from the Biscatche of the plains. — At the distance appeared to be more reddish in the breast; & tail with larger brush to it.

the constant desire to drag every hard object to the mouth of its burrow. Around each group of holes, many bones of cattle, stones, thistle stalks, hard lumps of earth, dry dung, &c &c are collected into a scattered heap, which frequently amounts to as much as a wheel-barrow could contain. I was credibly informed that a gentleman, when riding on a dark night, dropped his watch; he returned in the morning, & on the line of his road searched the neighbourhood of every Biscatche hole; & as he expected, he then soon found it. — This habit of picking up every kind of object which happens to lie on the ground anywhere near its habitation, must cost much trouble. The custom appears universal. I observed it to be the case near Mendoza, as well as throughout the province of Bueno Ayres. I am quite unable to form even the most remote conjecture for what purpose the Biscatche follows so strange & troublesome a habit. It cannot be for defence, because the rubbish is chiefly placed on the flat above the mouth of the burrow, which enters the ground at a very small inclination. No doubt there must exist some good reason. — But the inhabitants of the country, like myself, remain in perfect ignorance respecting it.

This they know because, the rabbits of their own accord do not spread to different parts of the Is^d & the two coloured sorts (a), being transported together, have produced young. — Rabbits of no kind are found in the small outgoing Is^ds & in the central parts of the great Is^d.

(a): It is rather curious to find how long these varieties of Black & Grey have been handed down amongst animals living in a perfectly wild state; the same fact happens with the cattle, which are as as variously coloured as in a heard in England. —

They assert they have seen piebald rabbits of many different varieties. The spots on the head of the specimens on board differ both one with another & with the description. Specimen (1902) is a head with a broad white band, the sides of which do not correspond: it had grey & brown hairs on its back & a white patch on one hinder thigh — it was a young animal. —

It has been advanced, as a strong argument for the distinctness of the species, that Magellan describes rabbits in the St. of Magellan. I feel no doubt that Magellan alluded to the Cavia cobaya which is a dark coloured animal & is to this day called Conejos ( rabbit) by the Spaniards. Anyhow Sealers & others who have been for years in those parts, never have heard of such an animal, or have seen their skins with the Indian people; whilst on the other hand mantles are made with the little skins of the Cavia C: are common. — If the above arguments are not thought conclusive against the existence of a Lepus Magellanicus — I will add that Bougainville when he came to settle at Berkeley Sound (when the black rabbits are now not uncommon) distinctly states that excepting the large Fox he found no other quadruped.

On the Island of Guche, a small thickly wooded Is^d in the Chonos Archipelago, there were many wild goats. — It is probable they have been turned out a century since.

Animals

Culpen. It is a fine large animal, wanders about by day, runs very fast. — I saw one chased by a dog; which it barked & whelped so precisely like its pursuer that I could not for some time distinguish from which of the two the noise proceeded. — This animal, & a bitch fox, had together destroyed at a farmhouse, during the previous year, no less than 200 fowls. — It is well known throughout Chile from its fearless manner of standing still & looking at any person who approaches it in a wood. — Molina says it is hence called Culpen, which in the Indian language signifies madness. — Molina thinks it is the same with the Fox of the Falkland Is^ds, which clearly is not the case. The Culpen is found in all the valleys & less desert parts of Chile, & it is probable that it is the same animal with the large fox. Killed at Port Famine in T. del Fuego. —(Zoolog Soc:) Pupils in dead animal appeared round & very large.-

Specimen (3188) is the Chilla of Molina. This small fox (which is full grown) was killed in the same valley of Copiapò with the Culpen. The inhabitants recognize it as a distinct species. Besides the valleys, it is found in very great numbers on the most desert Traversias, where scarcely a single plant besides a Cactus & occasional thorny bush grow; in such situations, however, & although quite destitute of water, the smaller rodentia abound, & it is on these that the Chilla subsists. This appears the only Fox which can subsist in such places. The Chilla is unable to run very fast; a

single good dog will generally catch it. It is said to be very numerous near Concepciòn, & is the same (I believe) which is also so very common on the great plains of Patagonia. Capt. FitzRoy has a specimen from the S. Cruz. —

Besides these two species there is the common Fox (Gurù of Molina; unfortunately I lost my specimen), which is decidedly different: it is common in central Chile; is the same as the specimens from B. Blanca. — Molina makes a fourth kind, Pagnè-Guru, & he says that in Chiloe it is found of a blackish colour. I have already mentioned (2431) this rare animal. But it appears to me very doubtful whether it is specifically distinct from the common Gurù. — Allowing these to be three species — the Vulpes Antarcticus of the Falklands makes a fourth, & the Wurrah (v. Falkner's) a fifth. — This latter animal has a peculiar long hair on its skin & is of a very different colour. It is found rarely all over La Plata & as far South as the R.

Animals

Vulpes antarcticus. This large wolf-like Fox is common in both East & West Falkland Is^d. It has by mistake been sometimes stated to be peculiar to one Is^d. — Various Gauchos & half-cast Indians have visited at different times these Islands; they all maintain no such animal is found on any part of the mainland of S. America. — The Sealers also assert it is not found on any other of the Islands in these Southern seas. — Hence I conclude that this tract of land, although so small, boasts of at least one species of Quadruped as peculiar to itself (also Rat?). These Wolves, or Foxes, are well known from Commodore Byron's description of their tameness & curiosity. To this day, their manners remain the same. They have been known to enter tents at night, & to steal meat from beneath the heads of the sleeping Seamen. The Gauchos have commonly killed them at night by holding out with one hand a piece of meat & having in the other a knife ready to stick them. — They are found in the inland parts of the Is^ds as well as on the coast. They burrow holes in the ground. Do not hunt in packs; are generally silent excepting in the breeding season, when they make a noise like a Fox. — Specimen in spirits (979) are the eyes; I do not know whether in this state it will be possible to discover the form of the pupil. — From the ease with which they are killed, their numbers rapidly decrease; already they are exterminated from the large peninsula formed by the heads of St Salvador Bay & Berkeley Sound, which composes a large part of the Eastern Is^d. — When these Isl^ds are settled, this Fox will in all probability within a few years be classed with

23

Animals

those animals which have perished from the surface of the Globe. — Out of the four specimens brought home in the Beagle, three will be seen to be no darker coloured, they come from the East Is^d. The fourth is smaller & rusty coloured, & is from the West Is^d. — Mr Lowe, who has been acquainted with these Islands for twenty years, & who is an accurate observer of Nature, asserts that this difference between the Foxes of the two Is^ds is invariable & constant. He says he has long since observed it. — An accurate comparison of these specimens will be interesting. I have omitted to add that the difference was corroborated by the officers of the Adventure. —

Cavia capybara, called also Carpincho. These animals are abundant on the borders of the lakes in the vicinity of Maldonado. Occasionally they frequent the Islands in the Plata where the water is quite salt. A fine female was shot at M. Video (sent in brine to the Zoolog. Soc.) She weighed 98 pounds. — Girth 3 ft 2 inches. Length from tip of snout to the tail 3 ft 8½ inches. Height from toes to top of shoulder 1 ft 9 inches. Near Maldonado three or four Carpinchos generally live together E: in the day time they are either lie amongst the aquatic plants or are feeding openly feeding on the turf plain. — When viewed at a distance, from their manner of walking & colour they resemble pigs — but when seated on their haunches & attentively watching any object with one eye, they reassume the appearance of their congeners the Agoutis Cavies. — The great depth of their jaw gives to their profile & front view a quite ludicrous aspect. They are very tame, by cautiously walking I approached within three yards of four large ones. (a) As I came

[23v]

(a): This happened near a lake a few miles from the Maldonado. There are no tigers in this part of the country, and the Gauchos do not think them worth hunting. Their unmolested state probably makes them so tame.

nearer, they frequently made their peculiar noise, which is a very low abrupt grunt: there is not much actual sound, but rather the sudden expulsion of air. The only noise I know at all like it is the first hoarse bark of a large dog. Having watched from almost within arm's length the four (& they me) for several minutes, almost within arm's reach; they rushed into the water at full gallop with the greatest impetuosity, & emitted at the same time their bark. — When three or more thus dash in together, the spray flies about in every direction. After diving a short distance, they come again to the surface, but only just show just the upper part of the head. (a) In the stomach & duodenum of one of these Carpinchos there was a great mass of a yellowish liquid matter, in which nothing could be distinguished. — The dung is in shape rounded oval; when dried & burnt it emits a pleasant smell like, but more agreeable than, that from Cedar wood. When the female Carpincho has young & is swimming in the water, the young ones are described as sitting on her back. — These animals are easily killed in numbers: but their skins are of trifling value, and the meat is very indifferent. I have never heard of the Carpincho being found South of La Plata. But as I see in a map that there is a Laguna del Carpincho high up the Rio Salado, I suppose such must have occurred has happened. On the Island in the Rio Parana they are exceedingly abundant & afford the ordinary prey of the jaguar. E

Puma. The Puma has a wide geographical range, from the Equinoctial regions to the extreme temperate zone. — It is common in all the Provinces of La Plata; numerous throughout Patagonia to the

(a): It was near a lake in this neighbourhood of Maldonado that I succeeded in getting so close to the four. Their tameness may probably be accounted for by the Jaguar having been for some years banished from the country, and by the Gauchos not thinking it worth while to hunt them.

25

Animals

forests of T. del Fuego, & in the Cordillera of Chile I have seen its footsteps at a height which could not have been under 10,000 ft. — In la Plata the Puma chiefly preys on Deer, Ostriches, Biscatche & the small quadrupeds; it there but seldom kills cattle or horses, & is not, excepting on most rare occasions when a female has young ones, dangerous to man. In Chile however, probably from the scarcity of wild animals, it destroys very many young cattle & colts; I have moreover heard of several instances where men & women have so met their fate. In Patagonia, & in the higher Cordillera, the Guanaco is the constant prey. In all cases the animal is destroyed by its neck being broken. It is said the Puma springs on the shoulders & with one paw draws backwards the head till the vertebrae give way. — After killing an animal, it eats its fill & then covering the carcase with many large bushes, lies down & watches it. But if the Puma has ever once been so discovered & hunted, it is asserted that it never resumes this habit, but after eating wanders far away. This habit of watching often betrays the Puma, for the Condors wheeling in the air above, every now & then descend to partake of the feast, & being angrily driven away, they all together rise on the wing again (Sir J. Heard, p. 483); by this means the Chileno Guasso knows where the Lion is lying & hurrys to the chace. — The Puma is easily killed; in an open country it is first balled, that lazoed, & afterward dragged along the ground until it is insensible. — At Tandeel (S. of the Plata) I was assured that within three months one hundred were destroyed. — In Chile, they are generally

26

Animals

driven into bushes, & are then either shot or are bated to death by dogs. The dogs employed in hunting the Puma belong to a particular breed, & are called Leoneros; they are weak, slight animals, something like a long-legged terrier. They are born with the instinct of springing at the Lion's throat & no other part. — I have been assured that one of these weak little dogs has been known single-handed to destroy its large antagonist. — The Puma is a very silent animal, even when wounded; rarely during the breeding season it utters a cry. — It is described as a very crafty animal; when hunted it will return on its former track, & then suddenly will make a spring on one side & then wait till the dogs have passed. — They frequent indifferently reeds, bushes & caves; often inhabit the most arid parts. — The flesh of the Puma is white & good; it is often used by the Gauchos in the wilder parts of the Province. — I have myself made a good supper on the hinder quarters. — Dr Shaw relates the same fact respecting the African Lion, but he was at first disbelieved. —

Jaguar. 10 The Jaguar is found not uncommonly in the Province of la Plata. The wooded banks of the great rivers appear its favourite haunts of these animals. South of the Plata, I have however heard of these amongst animals inhabiting the reeds bordering on lakes. — They seem to require water. — The Jaguar (a) has been killed on the banks of the R. Negro in Lat: 41^o; & Faulkner states the lake Naharil-Luapi takes its name from the Indian word for Tiger. The latitude of this lake is about 42^o (which corresponds to the situation of the Pyrenees in the Northern Hemisphere). —

[26v]

(a): The Jaguar does not appear in any part to have crossed to the West of the Cordillera.

N.B. I should say that all my information about the Puma & Jaguar has been obtained by conversing with several different country people.

[26b]

[Note] XX The Jaguar is a much more dangerous animal than is generally supposed. On the Parana they have killed many wood cutters and have even entered vessels. — There is a man now living in the Bajado who, coming up from below decks at night, was seized on the deck by a tiger; he escaped however with the loss of the use of one arm. — When the floods drive these animals from the islands, they are much the most dangerous. I was told that a few years since a very large one found its way into a church at St Fe. Two padres entering one after the other were killed, and a third who came to see what was the matter escaped with difficulty. — The beast was killed destroyed by the people unroofing one corner of the buidling and firing at it being shot from a corner of the building which was unroofed.

27

Animals

These jaguars animals are particularly abundant in the Isles of the Parana. Their common prey is the Carpincho; so that it is commonly said, where the Carpinchos are plentiful, there is little danger of the Jaguar. — Falkner states that near the mouth of the Plata, on the Southern side, that these animals are numerous, & that they chiefly live on fish; & this account I heard repeated on the Parana. XX The Jaguar is decidedly dangerous to man. — I have heard of several deaths (V. Journal). When the Parana overflows, they are obliged to leave the Islands, so XX They commit also at these times great ravages amongst the cattle & horses. As with the Puma, it is said they kill their prey by breaking the vertebrae of the neck; if driven from the carcase they seldom return. — The Gauchos say that the Jaguar, when wandering about at night, is much tormented by the foxes whelping as they follow him. This is a curious coincidence with the fact which is generally affirmed of the Jackalls accompanying in a similarly officious manner the East Indian Tiger. — The Jaguar is a noisy animal, roaring much by night, & especially before bad weather. — One day, when hunting on the banks of the Uruguay, I was shown certain trees to which these animals are said constantly to recur for the purpose of sharpening their claws. — During the day, I saw three well known trees. — In front the bark was worn smooth, & on each side there were deep scratches or rather grooves extending in an oblique line nearly a yard in length. The scars were of different ages. — To go and examine these trees is a common method of ascertaining whether a Jaguar is in the neighbourhood. —

28

Animals

I conceive this habit of the Jaguar is exactly similar to one which may any day be seen in the common cat, as with outstretched legs & exserted claws it scrapes the leg of a chair. — Some such habit must also be common to the Puma, for on the bare hard soil of Patagonia I have frequently seen scores so deep that no other animal could have made them. The object of this practice is, I imagine, to blunt rather than to sharpen, as the Gauchos think, the points of their claws, which are so seldom used. — The Jaguar is killed without much difficulty, by the aid of dogs baying & driving him up a tree, where he is dispatched with bullets.

Guanaco 10

15 15 (The Guanaco abounds over the whole of the temperate parts of South America, from the wooded islands of Tierra del Guego, through Patagonia, the hilly parts of la Plata, Chile, to the Cordillera of Peru. — Although preferring an elevated site, it yields in this respect to its near relative the Vicuña. On the plains of Southern Patagonia I have seen we saw them more numerous in greater numbers than in any other part. Generally they go in small herds, from five or six to thirty, but on the banks of the S. Cruz one single herd could not have contained less than five hundred. On the Northern shores of the St. of Magellan they are also especially numerous. The Guanacoes are generally very wild & wary. — Mr Stokes, when with a party, once saw through a glass a herd which evidently were going away from us at had been frightened & were running away at full speed, although their distance was so great that they were not distinguishable with the naked eye. — Frequently the sportsman

[28v]

[Note] Byron says when he is relating his disappointment on discovery water "that our people among other expedients had watched the guanacos & seen them tarry at the salt ponds."

29

Animals

receives the first intimation of their presence of a herd by hearing from a long distance the peculiar shrill neighing note of alarm; if he then looks attentively, he will perhaps see the herd standing in a line on the side of a distant hill. On approaching, a few more squeals are given, & the herd set off, at an apparently slow but really quick canter, along some narrow beaten track to a neighbouring hill. — If however by chance he should abruptly meet a single Guanaco or a herd, they will generally stand motionless & intently look at him — then perhaps move on a few yards, turn round & gaze again. — What is the cause of this difference in their shyness? Do they mistake a man in the distance for their chief enemy the Puma? Or does curiosity overcome their timidity? That they are curious is certain, for if a person lies on the ground & plays strange antics such as throwing up his feet in the air, they will almost always approach by degrees to reconnoitre him. It is an artifice which has been repeatedly practiced by our sportsmen: it has moreover the advantage of allowing several shots to be fired, which are all taken as parts of the performance. On the mountains of Tierra del Fuego, & in other places, I have more than once seen a guanaco, on being approached, not only neigh & squeal, but prance & leap about in the most ridiculous manner, apparently in (a) defiance, as a challenge.(a)

The Guanacoes readily take to the water; several times at Port Valdes they were seen swimming from island to island. —

[29v]

(a) These animals are very easily domesticated, & some are thus kept near the houses, although at large on their native plain. They are in this state very bold, & will readily attack a man by striking him from behind with both knees. — It is asserted that the motive for these attacks is jealousy for their females. The wild guanacos however have no idea of defence; a single dog will secure one of these large animals till the huntsman can come up. — They may be compared to sheep in many of their habits; the whole herd is easily bewildered & driven from one to the other side, which greatly facilitates the success of the Indian manner of hunting with the Bolas. For when they see men approaching in several directions they know not which way to run, & are then without much trouble encompassed. — In many of their habits they are like sheep in a flock, thus when they see men approaching in several directions they soon become bewildered & know not which way to run. This greatly facilitates the Indian method of hunting on horseback with the bolas, for they are easily driven to a central point and are encompassed.

30

Animals

Byron in his voyage says he saw the Guanacoes drinking salt water; some of our officers saw a herd apparently drinking the briny fluid from a Salina near C. Blanco. — I imagine in several parts of the country, if they do not drink salt water they either drink none or must travel long distances for it. — In the middle of the day, they frequently roll in the dust, in saucer-shaped hollows. — The males Guanaco often frequently fight together: two one day passed quite close to me, squealing & trying to bite each other; & several were shot with their hides deeply scored. — Herds of Guanaco appear sometimes to set out on exploring parties. At Bahia Blanca where they are extremely unfrequent within thirty miles of the coast, I saw one day the tracks of thirty or forty which had come in a direct line to a muddy salt water creek. They then must have perceived that they were proceeding directly towards the sea, for they had wheeled with the regularity of cavalry & had returned back in as straight a line as they had advanced. — The guanacoes have one singular habit which is to me quite inexplicable; namely that on successive days they drop their dung in one defined heap. I saw one of these heaps which was eight feet in diameter, & necessarily was composed of a large quantity of dung. — Frezier remarks on this habit as common to the Guanaco as well as to the Llama; he says it is very useful for the Indians, who use it for fuel & are thus saved the trouble of collecting it. There is also another singular fact, namely that the guanacoes (a)

[30v]

(a): have favourite spots for dying in. On the banks of the S. Cruz, the ground in certain circumscribed spaces which generally were bushy & all near the river, was actually white with bones. On one such spot I counted between ten & twenty heads. — I particularly examined the bones; they did not appear, as some scattered ones which I had seen, gnawed or broken as if dragged together by a beast of prey. The animal in most cases must have crawled before dying beneath & amongst the bushes. Mr Bynoe informs me that during the last Voyage he observed the same circumstance on the banks of the R. Gallegos. It remains to me inexplicable; I can only add that the wounded guanacoes at the S. Cruz invariably walked towards the river. — At St Jago in the C. de Verds I remember to have seen in a most retired ravine a

certain corner under a cliff where numerous goats' bones were collected. We at the time exclaimed that it was the burial ground of all the goats on the island. — I mention these trifling circumstances, because in certain cases it might throw light on the occurrence of a number of uninjured bones in a cave or buried under alluvial accumulations; and in explaining the cause why certain mammalian are more commonly embedded than others in sedimentary deposits. Any great flood of the S. Cruz would wash down many bones of the Guanaco, but probably not a single one of the puma, ostrich or fox. — I may also observe that almost every kind of waterfowl when wounded takes to the shore, so that fewer of their remains could be preserved than at first would be supposed. The Guanaco seems particularly liable to contain Bezour stones in its stomach. The Indians who come to trade at the Rio Negro bring great numbers to sell for "remedios" or quack medicins. I saw one old man with a box full of all sizes, large & small. — (15)

NB. I have dimensions of Specimen shot at Port Desire, especially about the foot, to compare with those killed in T. del Fuego, which are supposed by some to have broader feet.

I may instance islands in the Pacific, the Abrolhos in the Atlantic. — At the Galapagos (uninhabited island), the extreme broken land of T. del Fuego, the small wooded islands of the Chonos archipelago, besides Ascension just mentioned. — I may observe that several species of Rats & Mice become domesticated. Thus the Rat of S. America with reddish fur; the small brown rat introduced from the Mauritius into Keeling Isl^ds. Again, when crossing the plains between Buenos Ayres and the R. Negro, I saw in a small temporary hut

Animals

made of reeds, which had only been erected a few weeks previously in a country where for a distance of two hundred miles there were no houses, I saw several mice running about the thatch with the familiarity of the civilized English species. — On the other hand, at the Falkland Isl^ds (& I believe C. de Verd Islands) the common house mouse has taken to the country & lives far from houses. — Are the various specimens of mice which I have collected, varieties or species? Their geographical distribution often causes me to doubt. —

There is a peculiar character to all mice of S. America, slightly different from true mice, Mr Waterhouse excepted one (1237) which oddly enough inhabited houses of Maldonado, but this appears rather different from English mice.

From New Holland Mr Waterhouse has two species, though unlike each other (one of mine from K.

Sp. 1 Mus decumanus

In Mr Darwin's collection I find five specimens which appear to me identical with our common Rat, of these, two are from East Falkland Island and there is one from each of the following localities, Buenos Ayres, Maldonado, and Valparaiso.

Although these specimens differ somewhat in colour from our Common Rat, I can find no character of sufficient importance to induce me to consider them as distinct species. — The two specimens from East Falkland Island — compared with Mus decumanus — differ in being of a lighter and richer colour — the hairs of the back are tipped with reddish-brown or rust colour, whereas those of M. decumanus are of what I should term of an ochre-colour at their apee — the general hue of the latter is grayish whereas that of the former is inclining to red. —

The specimen from Valparaiso is intermediate in colour between the two just mentioned and those from Maldonado and Buenos Ayres agree in colour with the Falkland Island specimens. —

One may observe in the foregoing list that, the Patagonian & Chilian ones though distinct species generally go together, & that the Maldonado have likewise one character a character somewhat peculiar to itself.—

1832

Diodon — Bahia

March 10^th a Diodon was caught swimming in its unexpanded form near to the shore. — Length about an inch: above blackish brown, beneath spotted with yellow. — On head four soft projections: the upper ones longer like the feelers of a snail. Eye with pupil dark blue; iris yellow mottled with black. — The dorsal caudal and anal fins are so close together, that they act as one. These as well as the Pectorals, which are placed just before the bronchial apertures, are in a continual state of tremulous motion, even when the animal remains still. — The animal propels its body by using these posterior fins, in same manner as a boat is sculled, that is by moving them rapidly from side to side with an oblique surface exposed to the water.- The pectoral fins have great play which is necessary to enable the animal to swim with its back downwards. — When handled a considerable quantity of a fine "Carmine red" fibrous secretion was emitted from the abdomen, and stained paper, ivory &c, of a bright colour. — The fish has several means of defence it can bite hard, and can squirt water to some distance from its mouth, making at the same time a curious noise with its jaws. — After being taken out of water for a short time, and then placed in again, it absorbed by the mouth (perhaps likewise by the branchial apertures) a considerable quantity of water and air, sufficient to distend its body into a perfect globe. — This process is effected by two methods; the air is swallowed and then forced into the cavity of the body, its return being prevented by a muscular contraction which is externally visible. The water however, I ob-

Diodon — Bahia

served entered in a stream through the mouth, which was distended and motionless; hence this latter action must have been caused by the dilatation of the animal, producing suction. When the body is thus distended the papillæ, with which it is covered become stiff, the above mentioned tentacula on the head, being excepted. — The animal being so much buoyed up, the branchial openings are out of water, but a stream regularly flowed out of them which was as constantly replenished by the mouth. — After having remained in this state for a short time, the air and water would be expelled with considerable force, from the branchial apertures and the mouth. — The animal at its pleasure could emit a certain portion of the water and I think it is clear that the fluid is taken in partly for the sake of regulating the specific gravity of its body. — The skin about the abdomen is much looser than that on the back and in consequence is the most distended; hence the animal swims with its back downwards. — Cuvier doubts their being able to swim when in this position; but they clearly can not only swim forward, but also move round. — this they affect, not like other fish, by the action of their tails, but collapsing the caudal fins they move only by their pectorals. — When placed in fresh water seemed singularly little inconvenienced.
