undoubted deep-sea species is Pontostratiotes abyssicola, dredged 
in 2200 fathoms. This was previously described in MS. by Dr. 
von Willemoes Suhm as Lernea abyssicola: and was found on 
Ceratias uranoscopus dredged in 2400 fathoms. . 
Tunicates —M. L. Roule has studied the genus Rhopalea, an 
_ ascidian abundant near Marseilles at a depth of fifty to sixty 
_ meters. Rhopalea does not reproduce by budding, and may be 
_ considered as forming a link between the simple and the com- 
_ pound tunicates. 
Batrachians—M. G. Calmels finds in the poison of batrachians 
_ small portion of methylcarbylamine, which gives to the liquid 
= some of its odor and toxic qualities; it also contains, in larger 
= quantities, an acid from which the methylcarbylamine is formed. 
Birds, —Herr Stieneger informs Vazuren that Kamtschatka has 
four species of sea-eagle, Halaétus hypoleucus, H. albicilla, H. leu- 
_ ephalus;and Thalassaëtus pelagicus. The first of these is dis- 
_ tinguished from the others by the dazzling whiteness of some 
_ Parts of the body and by its generally lighter color. Among the 
cetacean crania collected, three seem to belong to a new species. 
tammals.—Dr. P. Albrecht, in a communication to the An- 
__ thropological Society of Brussels, maintains that there are primi- 
4 tively four intermaxillaries, and that hare-lip, which is never cen- 
3 tral, takes place by the separation of the inner and outer inter-. 
_ Maxillaries of one or the other side. As proof of this, he figures 
_ “ses of double hare-lip, in which the two inner bones (endogna- 
_ «t8)stand out as a separate bone anchylosed in the median line, 
a While each outer intermaxillary, bearing its incisor, is united to 
the Maxillary. In the Ornithorhynchus, as figured in a commu-
