ZOOLOGICAL LITERATURE. 
The author adopts the distribution of these Cetaceans into 
groups and genera which has been proposed by Eschricht^ and 
by Gray in tlie memoir of which an abstract is given above j but 
lie has worked out the characters more completely^ and for them 
we must refer to the paper itself. 
The specimens examined and described are the following : 
1. Balcena mysiicetus: skull, Leyden (p. 394) j skeleton, Brussels (p. 416). 
2. Exibalcena australis (?) : skeleton and skull, Leyden (p. 394) j skull, 
Louvain. 
3. Meyaptera longimana : skeletons in Leyden (p. 397), Brussels (p. 416), 
and Louvain (p. 418). 
4. Physalus antiquomm : skeletons in Antw^erp (p. 414) and in the Hague 
(p. 409) j skulls in Leyden and Louvain. 
5. Physalus latirostris, sp. n,, p. 410, from the coast of Holland : skeleton 
in Utrecht. 
6. Sibbaldius laticeps : skeleton in Leyden (p. 397), the identical specimen 
of No. 17 of Eschricht’s list in ^ Untersuch. iiher Nord. Walthiere.’ Another 
skeleton in Brussels (p. 417). 
7. Sibbaldius schleyelii, sp. n., p. 400, from the north-west coast of Java : 
skeleton in Leyden j a skull of a very young Whale, also from Java, in the 
Leyden Museum, probably belongs to the same species (p. 408). 
8. Palcenoptera rostrata : two skeletons in Leyden (p. 409), two in Brus- 
sels (p. 418), and one and a skull in Louvain (p. 418). 
M. Paul Gervais enumerates the species which have been 
obseiwed at different times on the French coasts of the Medi- 
terranean (Compt. Rend. 1864, ii. p. 876) j the author distin- 
guishes the foUowing species : 
1. Physeter macroccphalus. Very rare. A part of the lower jaw is pre- 
served in the collection of the Peres Maiistes, a la Seyne ” near Toulon. 
2. Ziphius cavirostris (Cuv.), The recent specimens found of this species, 
which has for a long time been considered extinct, have become types 
several nominal species, viz. Delphinus desmarestii (llisso), JDelphinus philippii 
(Oocco), Ilyperoodm doumetii (Gray), Ilyperoodon yervaisii (Duvernoy). 
3. Orca gladiator. Two specimens are referred to this species, one with — 
teeth j of the second, only the lower jaw is preserved, and as it has six teeth 
only on each side, its specific determination is rather uncertain. 
4. A species belonging to the genus Glohiocephalus has been recognized by 
M. Gervais j he considers it as scarcely distinct from the Pilot-Whale (^Cfl. 
svineval)y differing from it in the curvature of the external edge of the inter- 
maxillary bones and in the teeth being a little more obtuse. It is black, with 
a white longitudinal band on the belly, commencing at the throat, where it 
is heart-shaped, and extending on to the vent. 
5. Qrampus rissoanus (Cuv.). Hitherto found in the Mediterranean only. 
6. Delphinus {Tursiops') tursio. Tolerably common. 
7. Delphinus delphis. 
8. Delphinus tethyos, Gervais in Bull. Soc. Agricult, de lTI(5rault, 2nd ser. 
t. XX. p. 289, and Zool. et Pal<Sont. Fran§. p. 302. Known from two examples 
only.
