MOLAR TEETH AND OTHER REMAINS OE MAMMALIA. 
E’rom the above comparisons there can, I think, be no doubt as to the validity 
of Professor Meyer’s genus Sanitherium : I have not found among our Indian collec- 
tions any specimens which I can refer to the upper molars of this genus. This genus, 
with the addition of the next, gives the following list of Suina from the Tertiaries of 
India, a list equal in extent to that of the fossil Proboscidian fauna of India, viz , : — 
SUID^. 
Sus giganteus. 
Stis hysudricus. 
Anthracothbrid^ . 
Anthrac other um {Chceromeryx) silistrense. 
Hippopotamidjs. 
Hexaprotodon sivalense. 
Hexaprotodon iravadicim. 
Tetraconodontid^. 
Teiraconodon magnum 
HippoJiyus connects the Figs with Hippopotamus, and Sanitherium with the 
A nthracotheridce : Merycopotmius is a link between Hippopotamus and Hyopotamus, 
and so joins on with the Buminantia ; while Teiraconodon presents affinities in its 
molar teeth with Anthracotherium, and diverges from all other genera in its gigantic 
premolars ; it is a difficult question to decide whether Merycopotamus should be put 
into the same family as Hyopotamus {Anthracotheridrs) , with which it is so closely 
united by the form of the molars, or whether with the Hippopotamidm, with which 
it is connected by many points of its anatomy, most notably by the peculiar form 
of the lower jaw. Teiraconodon should, I think, without doubt be placed in a 
distinct family. 
Hippohyus sivalensis. 
Sanitherium Schlagintweitii. 
Merycopotamus dissimilis. 
Hexaprotodon namadictm. 
Tetraprotodon palaindieum. 
Genus Teteaconodon, ’Falconer. 
This genus of Hippopoiamoid Ungulates was formed by the late Dr. Falconer 
on the evidence of a portion of a lower jaw containing the ultimate and penultimate 
molars ; the specimen was found by Messrs. Baker and Durand in Siwalik strata 
between the Markanda Pass and Pinjdr ; it was figured by them in the Asiatic 
Researches” {ml, XIX, pi. 6, fig. 2) ; the figure has been copied in the “ Palae- 
ontological Memoirs” {vol. l,p. 150,^^. 5) to illustrate Dr. Falconer’s memoirs on 
the specimen ; in this memoir the specimen is described as being the right upper 
jaw ; this is the more strange, as Dr. Falconer himself says the last tooth is known 
to be the ultimate molar ‘‘ by having the accessory spur or process which charac- 
terizes this tooth this large accessory spur only occurs in the lower molars of the 
Ungulata, to which series the specimen undoubtedly belongs. Falconer’s specimen 
appears to have been lost, and no other specimens have hitherto been known till 
the discovery of the specimen described below.
