Rhinoceros. Dr. Gray has examined the specimens in the col-

Proc. Zool. Soc. 18G7, pp. 1003-103JJ, After some introductory 
remarks on the literature of this subject and the formation of the 
osteological collection in the British Museum, he gives a syn- 
opsis of the genera : in their definition as well as in the distinc- 
tion of the species he has been essentially assisted by the ex- 
amination of the skulls ; he has been thereby enabled to distin- 
guish three new species, the skulls of which are figured. Also 
fossil species are referred to the genera. The systematic arrange- 
ment is the following : — 
I. The skin divided into shields hy well-marked folds. Skull with the inter- 
maxillary free y elongate; upper cutting-teeth long ; nasal hones produced^ 
conical. Asiatic Rhinocerotes. 
1. Rhinoceros. Horn single, anterior. Lumbar and neck-folds of the skin 
well developed. Part of the occipital bone, near the occipital condyle, 
and the condyles themselves prominent. — To this genus are referred the 
three new species ; and therefore we add the synopsis of all the species. 
A. Forehead and nose behind the horn flat. {Rhinoceros*.) 
Nose square on the sides above ; nasal short. R.javanicus. 
Nose shelving on the sides above j upper jaw slightly contracted be- 
fore the grinders. 
Nasal broad, elongate. R. unicornis. 
Nasal narrow, short. R. nasalisy sp. n., p. 1012, from Borneo. 
Upper jaw much contracted before the grinders ; nasal narrow, short. 
R.Jloweriy sp. n., p. 1016, from Sumatra. 
B. Forehead and nose subcylindrical, shelving on the sides above ; nasal 
elongate. {Eurhinoccros* .) R.stenoccphaluSy&^.n.y'^.lOlSy'heih. — P 
2. Ceratoriunus. Horns two, one behind the other. Lumbar and neck- 
folds of the skin rudimentary. Occipital end of the skull flat. Condylo 
not prominent. R. sumatranus = R. crossii. 
II. Skin uniform, not divided into shields. Horns two. Skull : — intetmasa 
* The author informs me that these two subgeneric names have been re- 
versed in the original, and that they should be placed as in this abstract.
