122—18 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
1 , 
In size tliese teetli agree very closely witli tliosei- of 0. duvaucelli] and they also 
agree in the contour of their outer surface, and in tli-e flatness of their masticating 
surface^ ; but differ by the more rugose enamel, tl^ie distinct cingulum, and the 
smaller size of the accessory inner column. \ 
Lower molars. — The lower molars mentioned abojve are represented in vol. I., 
pi. VIII., fig. 5 : they are the two last teeth of thfe right side, in a well-worn 
condition, and were obtained from the Siwaliks of the Punjab. They agree with 
the upper molars in their short crowns, rugose enamel, Isize, and the flatness of the 
masticating surface of the crown when well worn (lYV)l 
Affinities. — The present specimens are insufficient tcj) determine the full affinities 
of the species to which they belonged ; and as the writer has not an opportunity of 
comparing them with the teeth of all species of the genus their specific distinctness 
cannot be insisted on ; so that the name C. sivalensis must be regarded as provisional. 
Their interest lies in the fact of their proving the existence of a third species of 
Siwalik deer, and thus showing that the group was strongly represented in that 
period.^ I. 
Distribution. — The remains noticed above were obtained from the Siwalik Hills 
and the Punjab. 
Synopsis of Siwalik and Naebada Mammalia. 
Introductory. — The present synopsis includes all the specifically named mammals 
from the Siwaliks and Narbadas (together with Rhinoceros deccanensis\ and the best 
defined of the unnamed forms. 
The hope expressed in Prof. FloAver’s recently published Catalogue of the 
Mammalia in the Museum of the Royal College of Sm'geons^ that the generic and 
specific names therein employed might receive general adoption has induced the 
present writer to follow in the main that nomenclature ; and it has accordingly been 
necessary to change some of the names employed in the earlier parts of this work. 
The use of subgeneric names has been entirely abolished ; and the writer desires 
that the names given in the synopsis should be adopted for the future. The reference 
to each genus indicates the passage in which it was originally named ; and in the 
case of species the first reference indicates the first publication of the name, and the 
second the place where a fuller description is given : in cases where the naming of a 
species is coincident with its description but one reference is given. The generic 
references are in many cases given on the authority of Prof. Flower. 
1 The molars of the samhar (C. arutotelis, Cuv ) are slightly larger, and are readily distinguished hy the conca%dtyof the 
middle part of the outer surface of each lobe. Those of C. kashmirianus, Falc. (which agree very closely with those of C. 
elaphus and G . canadensis) are of the same size, but have the cost® less deeply marked, and the worn masticating surface 
thrown into deep ridges and grooves. 
2 An imperfect Siwalik cranium in the British Museum (No. 39,590) possibly indicates a fourth species of Cervus. The 
molars are brachydont, and are smaller than those of C. sivalensis. A fragment of a mandible in the same collection 
corresponds in size with this cranium.
