ZOOLOGICAL LITERATURE. 
/ 1. O.juhata (Forst.), from Juan Fernandez, Peru, The author was at 
' first (pp. 264-209) inclined to regard O. leonina (F. Cuv.) from the eastern 
coast of South America and Falkland Islands, O. hyronia from the Marian 
Islands, and O. yoch^royi (sp. n., p. 2GG, taf. 1) from the Cliincha Islands as dis- 
tinct species’ j but having examined the typical example of 0. h/ronia (a skull 
in the Collection of the Eoyal College of Surgeons, badly figured by Blain- 
ville) and other specimens, he entertains doubts on tliis point, referring to an 
observation of Prof. Eeinhardt, who himself obtained two skulls of old seals 
on the Chinclia Islands, one of which agrees with O. godeffroyi, whilst the 
other, much older (with a third of young age), differs much in the structure 
of the palate. 
2. O. idloce (Tschudi). The author has examined and figures the skull 
of the typical specimen (p. 667, with plate) j it does not belong to Phocarc- 
tos, as he believed previously, p. 270. 
b. Zalopkus (Gill). Like Otaria^ but with the osseous palate slightly 
concave in front, and deeply emarginate posteriorly. 
3. O. lohata, Gray, from New Holland. 
4. O. gilliesjni— O. stelleri (Schleg.), from California and Japan. — ^The 
latter is not identical with O. lohata, as believed forn^erly, 
c. Phocarctos (Ptrs.). No under-fur j ears longish (3 cm.) > palate con- 
cave, with its hind margin distant from the hamuli pterygoidei j molars dis- 
tinctly lobed. 
6. O. hooheri (Gray), from the Falkland Islands and Antarctic Ocean. 
d. Eumetopias (Gill). No under-fur j ears longish (3 cm,) ; palate con- 
cave behind, and terminating at a great distance from the hamuli ptery- 
goidei. 
6. 0. stelleri (Less.) = 0. calif orniana (Less,) = Arctocephalus monteriensis 
(Gray). Behring’s Straits, California. 
e. Arctocephalus (F, Oviv.). flairs with under-fur,* ears longish (3 or 4 
cm.) ; palate slightly concave, deeply emarginate behind ^ mandible with 
distinct posterior angle. 
7. O. pusilla (Schreb.) = Arctoe. ursinus (F. Cuv.) = O. delalandii (F. 
Cuv.)= O. ursina, part, (Nilss.)=5 O. lamarii, part. (lVIull.)==.^4rc^oc, delalandii 
(Gray), from South Africa. 
8. O, cinerea (Peron and Les,) = O. ursina, part, (Nilss.) == O, lamarii, part. 
(Mull), from New Holland. 
f. Arctophaga (Ptrs.). Hairs with a dense under-fur j ears longish (3 or 
4 cm.) ; palate slightly concave, deeply emarginate behind j mandible with- 
out posterior angle ; molars distinctly lobed. 
9. O. falklandica (Shaw, Burmeister) = nigrescens (Gray). 
From the Falkland Islands and east coast of South America. 
9^ Otaria philippii is described as a new species (p. 276, taf. 2. A, B, 
C) 5 from Juan Fernandez, 
g. Callorhinus (Gray). Hair with dense under-fur; ears longish (3 or 
4 cm.) ; palate moderately concave in front, flat behind, and deeply emar- 
ginate ; mandible with distinct lower posterior angle ; mandibulary process 
directed outwards ; molars not lobed. 
10, O. ursina (L.) ; Behring’s Straits, Washington Territory. 
The author has worked out the synonymy of the species men- 
tioned. He shows that the materials at present existing in col-
