ornata. A nearly perfect Acarus was found within the utricle or neck of one leaf, but in which of the two was not recorded. Genlisea aurea (Brazil). A fragment of the neck of a utricle was lined with transverse rows of hairs, and was furnished with elongated papillae, exactly like those within the neck of Genlisea ornata. It is probable, therefore, that the whole utricle is similarly constructed. Genlisea filiformis (Bahia, Brazil). Many leaves were examined and none were found provided with

SECONDE PRÉFACE Je profite d'une nouvelle édition de mon journal pour corriger quelques erreurs. J'ai dit à la page 38 que la plus grande partie des coquillages enfouis avec les mammifères éteints à Punta Alta, près de Bahia Blanca, appartenaient à des espèces encore existantes. Ces coquillages ont été depuis examinés par M. Alcide d'Orbigny et il déclare que tous sont récents (Observations géologiques dans l'Amérique méridionale, p. 83). M. Auguste Bravard a dernièrement décrit cette région

cellulaires. Comme il était encore de bonne heure au moment de notre arrivée, nous prenons des chevaux frais, un soldat pour nous guider, et nous partons pour la sierra de la Ventana. On aperçoit cette montagne du port de Bahia Blanca, et le capitaine Fitz-Roy estime sa hauteur à 3 340 pieds (1 000 mètres), altitude fort remarquable dans la partie orientale du continent. Je crois être le premier Européen qui ait gravi cette montagne ; un fort petit nombre même des soldats de la garnison de Bahia

crue ; or je remarquai invariablement que l'extrémité de la queue venait s'appliquer à la bouche pour déposer une goutte de fluide sur la viande que l'insecte était en train d'avaler. Malgré une pratique si constante, la queue ne semble pas pouvoir trouver facilement la bouche ; tout au moins, la queue va-t-elle d'abord toucher le cou, qui semble lui servir de guide. Un scarabée, le pyrophore à bec de feu (Pyrophorus luminosus, Illig.), est l'insecte lumineux le plus commun des environs de Bahia

Dans bien des endroits, le sol est recouvert d'efflorescences salines, et je retrouve des plantes qui se plaisent au milieu du sel, plantes si communes dans les environs de Bahia Blanca.

The main plain surrounding Bahia Blanca I estimated at from 200 to 300 feet; it insensibly rises towards the distant Sierra Ventana. There are in this neighbourhood some other and lower plains, but they do not abut one at the foot of the other, in the manner hereafter to be described, so characteristic of Patagonia.

ceed; but if, as I believe, the upper escarpments once formed the shores of an estuary, in that case the sandstone formation of the river Negro would have afforded an inexhaustible supply of sand, which would naturally have accumulated on the northern shore, as on every part of the coast open to the south winds between Bahia Blanca and Buenos Ayres. At San Blas (40 40 S.), a little south of the mouth of the Colorado, M. d'Orbigny1 found fourteen species of existing shells (six of them

of Mexico, and the Jesuit Falkner and other authors1 state that they occur at intervals over the vast plains extending from the mouth of the Plata to Rioja and Catamarca. Hence it is that during droughts, most of the streams in the Pampas are saline. I nowhere met with these incrustations so abundantly as near Bahia Blanca: square miles of the mud-flats, which near that place are raised only a few feet above the sea, just enough to protect them from being overflowed, appear, after dry weather

, homogeneous, fissile layers or folia, and in this case the rock is both foliated and has a cleavage. By stratification, as applied to these formations, I mean those alternate, parallel, large masses of different composition, which are themselves frequently either foliated or fissile, such as the alternating so-called strata of mica-slate, gneiss, glossy clay-slate, and marble. The folia of the gneiss within a few miles round Bahia generally strike irregularly, and are often curvilinear, dipping in

At the settlement of Bahia Blanca, the uppermost plain is composed of very compact, stratified tosca-rock, containing rounded grains of quartz distinguishable by the naked eye: the lower plain, on which the Fortress stands, is described by M.

the elder geologists, that a zone of trap is uniformly spread out beneath the granitic series, which composes, as far as we know, the foundations of the earth's crust? Is it not more probable, that these dikes have been formed by fissures penetrating into partially cooled rocks of the granitic and metamorphic series, and by their more fluid parts, consisting chiefly of hornblende, oozing out, and being sucked into such fissures?
