consequently that Mr. Pentland’s original determination of the pentecuspid upper 
molar as Anthracotherium silistrense was correct, but that the tetracuspid teeth, forming 
M. Pomel’s genus Choeromeryx , had been included in the same species. It was also 
shown at the same time that the mandible on the evidence of which the species 
A.' punjabiense had been founded, belonged in all probability to the same species as 
Mr. Pentland’s specimen of Anthracotherium. 
Upper molars.- — The type specimen is represented in figures 4 and 5 of plate 
XLY. of the second volume of the second series of the “Transactions of the 
Geological Society ” ; a far better representation of the specimen is, however, given 
in figures 23 and 23a of plate LXVIII. of the “Fauna Antiqua Sivalensis.” The 
latter figure shows that the tooth is a partially worn upper true molar of the left side, 
probably the last tooth of the series. The original specimen is stated to have been 
presented to the Geological Society, but, as It cannot now be found in their collection, 
the identification of the species must rest upon the figure, which is fortunately amply 
sufficient. The two teeth represented in figures 10 and 12 of plate XXIII. of the 
present memoir, were obtained by Messrs. Blanford and Fedden, from the lower 
Manclihars of Sind, one of them being the specimen referred to in the notice already 
quoted. These teeth belong to the true molar series of the right side, the specimen 
represented in figure 10 being partially worn, while the other is an unused germ : the 
former is probably a third, and the latter a second true molar, and both evidently 
belong to the same species. If figure 10 be compared with figure 23 of the above 
quoted plate of the “ Fauna Antiqua Sivalensis,” and if it be remembered that the 
teeth belong to opposite sides, of the jaw, there will be no question as to the specific 
identity of the two, whence the Sind teeth are identified with Anthracotherium 
silistrense of Mr. Pentland. 
With regard to the correctness of the generic determination of the latter, a 
comparison of the figures of either of the three Indian teeth with those of typical 
European species of Anthracotherium , such as A. alsaticum, 1 or A. magnum , 2 will at 
once show that the former are correctly referred to the same genus. There does not, 
however, appear to be any European species with which the Indian teeth can be 
identified, and, their original reference to a distinct species may, therefore, stand. 
The European species which approaches nearest in size to the Indian, form is 
Anthracotherium breviceps from the lower miocene, or oligocene, brown-coal of Bonn : 
the figure of the upper molars of this species given by Dr. Bottger 3 shows, however, 
that the inner columns form much more distinctly defined crescents than in the 
Indian teeth, and there is a more pronounced ‘ cingulum ’ in the former. The teeth 
of A. alsaticum , the figures of which have already been referred to, are of larger 
size than the Indian specimens, but agree very closely in general form, except that 
in the former there is a more distinct ledge at the bases of the external walls of the
