Memoirs of the Geological Survey of India. Palaeontologia 
Indica, being Figures and Descriptions of the Organic 
Remains procured during the progress of the Geological 
Survey of India. Indian Tertiary and Post Tertiary Verte- 
brata. Vol. i., 2. Ser. x., 2.- — Molar Teeth and other 
remains of Mammalia, by R. Lydekker, B.A. Calcutta : 
Geological Survey Office. London : Triibner and Co. 
The remains here described and figured belong to Rhinoceros 
palceindicns, R. sivalefisis, R. platyrhinus, R. iravadicus (a new 
species), R. planidens , and Acerotherium Perimense. If we 
include both extinct and living forms the total number of species 
of Rhinocerotes found in South-Eastern Asia is fifteen, whilst 
there is evidence of three further species from Burma, Attock, 
and Sind respectively. Of ruminants we find a description of 
Vishnutherium iravadicum , or at least of its teeth and a frag- 
ment of its jaw. Till the entire skull is obtained it will be diffi- 
cult to say whether this extinCt form was most nearly allied to 
Sivatherium or to Camelopardalis. Of this latter genus there is 
a figure and description of the remains of C. sivalensis. Next 
follow Bramatherium Perimense, Camelus sivalensis (a specific 
name which we fear occurs too often), and Dorcatherium majus 
and minus (two new species). Cervus latidens was the largest 
of the Cervidre of Siwalik, its teeth equalling in size those of 
the Irish elk. The other Cervidae are C. triplidens and C. sim- 
plicidens. The teeth of Listriodon pentapotamice might be mis- 
taken for the lower molars of Tapirus were it not for their square 
form. Dinotherium pentapotamice is distinguished from the 
European species by its much smaller size. The teeth of Sani- 
therium Schlagintweitii are distinguished from those of Sus by 
the greater simplicity and distinctness of the main tubercles ; by 
the hinder lobe being relatively larger and taller ; and by the 
plane of wear being more oblique. Tetraconodon magnum , a 
hippopotamoid animal, is characterised by the abnormal develop- 
ment of its pre-molar teeth, which are considerably larger than 
the two molars. 
The edentate animal, Manis Sindiensis, had the same general 
organisation as the living species. Amphycyon palceindicus , a 
carnivorous animal approximating to the ursine group, was nearly 
as large as the polar bear. 
Ser. ii., 2, contains descriptions and illustrations of a number 
of fossil plants discovered in the Jurassic (Lias) formation of the 
Rajmahal Hills. This flora has a mesozoic character; it is much 
more numerous than that from Kach, both in species and speci- 
mens. Its chief types of the Rajmahal flora are in the class of 
Cycadeacere and some genera of ferns.
