177—36 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA 
While, however, the mandible of A. hippoideum is smaller, one of A. magnum figured 
by Prof. Owen 1 and De Blainville 2 has almost precisely the same dimensions as [the 
present specimen ; while a comparison of the latter with a cast of the former has 
shown that no points of distinction can be drawn between them. Other specimens 
of A. magnum are, however, somewhat larger. As the present specimen is too large 
to have belonged to either of the anthracotheroids of which the upper molars are 
figured in plate XXIY. (to which the mandibles figured in plate XXV. are provision- 
ally referred), it seems to indicate a new Indian species of the group. Its 
resemblance to A. magnum is so close as to render it certain that it belongs to that 
genus, and possibly to that species, although the specimen is too imperfect to decide 
the latter point. The dimensions of the specimen are as follows, viz. : — 
Depth at third lobe of m. 3 . . . 2'7 Length of m. 3 . . 2'7 
,, ,, first „ „ ,, „ . . 2-7 Width ,, ,, ,, . 1-33 
It may be added that the mandibles figured in plate XXY. indicate forms not closely 
allied to A. magnum or A. hippoideum. The range in time of the former species in 
Europe is from the upper eocene (Quercy phosphorites) to the lower miocene. 3 4 
Additional European species. — In mentioning the number of species of 
Anthracotherium on page 148 an important paper by Prof. Renevier, cited in the 
foregoing list, had escaped the writer’s notice. In this paper the species A. valdense, 
Kow, and A. laharpei , Ren., are described and figured; while A. minus , Cuv., is 
admitted as a species. All three species, which have been obtained from the Swiss 
miocene, must be added to the list given on pp. 149-9, bringing the number of well- 
authenticated species to eleven. 
The only one of these species coming near to either of the Siwalik species is 
the form referred to A. minus f which is nearly the same size as A. silistrense. The 
upper molars have, however, a more distinct cingulum, with the inner columns more 
markedly crescent-shaped : the mandible is, moreover, of a more slender type ; 
while tire lower molars have a very conspicuous cingulum.
