MOLAR TEETH AND OTHER REMAINS OE MAMMALIA. 
This specimen differs from the last chiefly by the smaller size of the cingulum, 
and its cuspidated character ; the difference may, perhaps, not be more than an 
individual variety. The dimensions of the specimen are as follows ;• —

Variety h—from the Siwalilcs of the Fotwar. 
The specimen of this variety consists of a portion of a left upper jaw {Vlate 7, 
fgs. 4 and 6) containing the second and third molars. On the inner side the 
teeth differ from the Attock form only by the cingulum being more closely applied 
to the surface of the barrels. 
On the outer surface {fig. 6) there is a considerable difference in the two 
forms. The Siwalik has much simpler and slighter costse than the Attock form ; on 
the posterior lobe ( right side of fig. 6 ) the hind costa is a very slight and simple 
ridge, without any reflection, totally different from the broad reflected costse of the 
Attock form ( left side of fig. 9 ) ; the anterior costse on both lobes are also much 
simpler in the Attock than in the Potwar form. The size of the two forms is very 
similar. Till specimens of the crania are obtained, it is impossible to say whether 
these differences indicate more than individual varieties ; all the specimens from the 
Potwar, however, in the Indian Museum are similar to those figured.

This species chiefly differs from the preceding by the much smaller size of the 
teeth; we have specimens in the Indian Museum showing both the molar and pre- 
molar series, so the smaller size of the teeth cannot be due to their being the milk- 
molar series of H. majus. The specimens figured are the penultimate and ultimate 
molars of the right side of the upper jaw. The teeth present the same general 
form as those of the larger species from the Siwaliks ; the costse are, however, rather 
less prominent : —

Genus Ceevus. 
Of this genus Falconer announced the discovery of two species from the 
Siwaliks (“ Val. Mem.f vol. I, p. 23), but these were never named or described, 
and I am not aware on what materials the species were founded. In the Indian
