MOLAU TEETH AND OTHER REMAINS OE MAMMALIA.

wMcli prevailed in former times ; should a skull with teeth he hereafter discovered, 
there will he no difficulty in assigning it to its respective species. The same 
remarks apply to other animals, of many of which we only possess single teeth. 
The following species or genera are now for the first time made known or fully 
described 
Listriodon pentapotamim^ Ealc. sp, 
Mhimoeros planidens^ nobis. 
MMnoceros iramdicm, nobis. 
Cerms triplidens^ nobis. 
Cerms simplicidem^ nobis. 
Cerms latidens^ nobis^ 
Dorcatherium majus, nobis. 
Dorcatherium minus, nobis. 
Vishnutherium iravadicum, nobis. 
Dinotlierium pentapotamicB, Ealc. 
Manis sindiensis, nobis. 
AmpMcyon palceindiGus, Ealc. et nobis. 
I have here to mention my obligations to Dr. Anderson, the Director of the 
Zoological Department of the Indian Museum, for his kindness in furnishing me 
with specimens of the osteology of living mammals for comparison with the fossil 
forms. 
Order: UNGULATA. 
Div. PERISSODACTTLA, Genus Rhinoceros. 
In the Eauna Antiqua Sivalensis/’ the late Dr. Ealconer distinguished three 
well-marked species of Rhinoceros the remains of which had been found in the 
strata of the Sub-Himalayan Siwaliks; these species were respectively named 
R. sivalensis, R. palcBindicus, and R. platyrhinus ; aU. these species were founded 
upon well-preserved crania. A fourth species, E. namadicm, from the Nerbudda 
was named in manuscript, but only a few limb bones from this locality are figured 
in the Eauna Antiqua Sivalensis.** Beyond a short description of the cranium of 
R. simlensis, given by Messrs. Baker and Durand in the Journal of the Asiatic 
Society of Bengal for 1836, no description of any of the above has appeared. A 
fifth species of the allied genus Acerotheriura was also determined by Dr. Ealconer 
on the evidence of molar teeth obtained from the ossiferous beds of Perim Island in 
the Gulf of Cambay : the name of A. perimense was assigned to this species. 
Since Dr. Ealconer’s death another species—i?. deccanensis, described by Mr. 
Eoote in the first part of the present volume — ^has been added to the Indian fossil 
fauna : this species was probably of Pleistocene age ; from Pliocene strata in 
China, Professor Owen has described molar teeth of another species, R, sinensis, 
allied to R. sumatrensis. 
With the exception of a figure of an isolated upper molar tooth of R. platyrhinus, 
the teeth of all the species of Rhinoceros figured in the “ Eauna Antiqua Sivalensis” 
are drawn on so small a scale, and the specimens themselves are generally so 
imperfect, that the figures, which have no accompanying description, are almost 
useless for the specific determination of detached molar teeth.
