guess vaguely and darkly at tke true affinities of their owners; even, however, the 
bare knowledge of the existence of such highly interesting forms of older mam¬ 
malian life, has a great importance in all schemes for the classification and evolu¬ 
tion of the most specialized class of Vertebrates. 
Many of the sj)ccimens noticed in the present paper will not require further 
illustration, and they are therefore described at some length; others, again, will 
require figuring and more minute description on a f uture occasion, and are there¬ 
fore only shortly noticed in the present paper. 
Commencing with the genus CawieZopartfaZis, we may notice that but few molars 
have hithei'to been found, and that consequently the present specimens considerably 
enrich our knowledge of the Indian fossil species. In the true upper molars I 
have only found evidence of one species, namely, C. sivalmsis; certain lower 
molars and premolars, however, seem to indicate the foimer existence of a second 
larger species, and of a third smaller species. 
The specimens collected by Mr. Theobald are the following: a portion of a 
left maxilla containing the three molars; a portion of a right maxilla, which 
seems to have belonged to the same individual, and contains the two last pre¬ 
molars and the two first molars; the two last upper molars of the right side ; 
two detached penultimate upper molars; two detached upper first molars; a 
single last upper promolar of the right side; a portion of a right maxilla con¬ 
taining the two last milk-molars and the first permanent molar; a fragment 
of a left ramus of the mandible containing the two last permanent molars; 
another fragment containing the last tooth of the opposite side, from beds low in 
the series; a firet right lower molar; a last right lower premolar of large size; 
a penultimate left lower premolar; the two anterior premolars in a fragment of 
the right ramus of the mandible belonging to a larger species : and the last lower 
milk-molar of the left side. 
The teeth of the fossil Siwalik G-iraffe hitherto figured and described are 
the two last upper molars, the penultimate upper premolar, the three lower 
molars, and the last lower premolar; all the above specimens were obtained by 
Dr. Falconer and ai’e figured on plate 16 of the “ Palceontological Memoirs.” In 
addition to the above, a fragment of a mandible with the last premolar and two 
first molars, obtained by Mr. Theobald from the Punjab, has been figured by 
myself in the “ Palisontologia Indica.” ‘ 
In the present paper I shall notice the moj-e important of the recently-dis¬ 
covered specimens, gi’s ing the dimensions of some of them. As the majority of 
these specimens do not differ in character from the coiresponding teeth of the 
living Giraffe, they do not I’equiro minute description, nor will it be necessary to 
give figures of them. 
The two most perfect specimens of the maxilla contain between them the five 
last teeth; of these T have appended the measurements, which are given in the 
first column (a) of the following table; in the second column (b) I have given
