dots alluded to by Mr. Darwin, are the lines of pores. There are two longitudinal dark lines on the dorsal, the uppermost serving as an edging: the anal also is edged in the same manner, especially posteriorly. Habitat, Bahia Blanca. This species was found by Mr. Darwin cast up on the beach at Bahia Blanca, where he states that it is not uncommon. It approaches so closely the B. porosissimus of Cuvier and Valenciennes, that I dare not consider it as distinct without comparison. Yet it differs

. Habitat, Bahia Blanca and Monte Video. This species, which has the general characters of the M. Cephalus of the European seas, is probably the M. liza of Cuvier and Valenciennes; but the specimens are in a bad state of preservation, and some of the characters cannot be accurately ascertained. The depth of the body appears to have been rather greater than what is mentioned in the Histoire des Poissons: there is also some appearance of small scales on the second dorsal and anal, which, according to

a mile. Part of this reef is very symmetrical, and has a uniform breadth of 200 yards. The coast of Brazil is in many parts fringed by reefs. Of these, some are not of coral formation; for instance those near Bahia, and in front of Pernambuco; but a few miles south of this latter city, the reef follows* so closely every turn of the shore, that I can hardly doubt it is of coral: it runs at the distance of three quarters of a mile from the land, and within it the depth is from ten to fifteen

As Cuvier observes, the D. geometricus of Bl. and Schneid.* approaches very closely this species, and I can hardly think it to be distinct.

As Cuvier and Valenciennes have mentioned individuals of this species, which varied in the number of rays in the soft dorsal from twenty-two to twenty-four, I cannot but consider the two above described as specifically the same, though in the first these rays amount to as many as twenty-five. This, which is the larger specimen, was taken by Mr. Darwin at Bahia Blanca, where it is said to have been common. The other was obtained at Maldonado. 2. UMBRINA OPHICEPHALA. Jen.

having vomerine teeth, and four rays in the ventrals, as well as in the general disposition of the markings; but no mention is made in the Histoire des Poissons of the nuchal filaments, which, however, may have been overlooked, as they are small and simple, and not very obvious. If it be identical with that species, its range in the Atlantic must be considerable, as the S. vomerinus is found on the coast of S. America, near Bahia. Generally speaking the same species are not observed on both

There is one specimen from Bahia Blanca which has also some small "buff-orange" spots on the upper part.* Mr. Darwin observes that "the appearance of the vermilion colour is as if the animal had crawled over a newly painted board;" and he adds—"This Toad inhabits the most

Found at Bahia Blanca by Mr. Darwin. The specimens are probably all of them very young; hence the longitudinal lines can scarcely be considered as permanent, as most species of the genus are beautifully lineated in the young state. The length of the tail, with its carinated scales, the general elegance of the form, the gracile form of the head, and the neat and distinct arrangement of the colours, render this one of the most beautiful species of this elegant genus.

When we were at Bahia, an elater or beetle (Pyrophorus luminosus, Illig.) seemed the most common luminous insect. The light in this case was also rendered more brilliant by irritation. I amused myself one day by observing the springing powers of this insect, which have not, as it appears to me, been properly described.* The elater, when placed on its back and preparing to spring, moved its head and thorax backwards, so that the pectoral spine was drawn out, and rested on the edge of its sheath

The first extends ten degrees further south than any other kind: a fourth species, the Mulita, does not come as far south as Bahia Blanca. The four species have nearly similar habits; the peludo, however, is nocturnal, while the others wander by day over the open plains, feeding on beetles, larv , roots, and even small snakes.
