15351. The third right lower true molar in a half-worn condition, 

 (Fig.) and containing ten ridges. Figured by Falconer and 

 Cautley, op. cit. pi. xii. figs. 12, 12 a. The ridges are 

 unusually narrow, placed very close together (the space 

 occupied by three ridges being only 0,054), and have but 

 a very slight mesial expansion. The contrast in this 

 respect between the present specimen and No. 36696 is 

 very great, but they are connected together by insensible 

 gradations, and the variation is enhanced by the difference 

 in the degree of wear of the two specimens. 



Cautley Collection. Presented, 1842. 



M. 1997. Fragment of the right ramus of the mandible, containing 



mT3, which has been longitudinally and vertically bisected. 



Transferred from the Old Indian Museum, 1880. 



M. 3087. The greater part of the third right lower true molar. 



(Fig.) Figured by Falconer and Cautley, op. cit. pi. xi. fig. 5, and 

 pi. xviii. A. figs. 2, 2 a ; the ridges (of which eight remain) 

 are placed wide apart. Presented by Dr. Hugh Falconer. 



The two following specimens were referred by Falconer to the present 

 species ; they have, hoivever, the ridge-formula of E. hysudricus, 

 and their enamel is more plicated and the ridges more 

 approximated than is usual in the present form, and the second 

 of them is almost indistinguishable from a tooth of E. hysudricus 

 (No. M. 3145) ; they may indicate a form connecting the two 

 species. 



M. 3088. Part of the right ramus of a mandible, containing a frag- 

 ment of m . 2 and the partially worn m . 3, which has 

 fourteen ridges. Noticed in 'Falconer's Palaeontological 

 Memoirs,' vol. i. p. 434, note 3.

M. 3083. Part of the left ramus of the mandible, containing the 

 (Fig.) half-worn m . 3, which has fourteen ridges. Figured by 

 Falconer and Cautley, op. cit. pi. xii. fig. 13.

The following specimen is not specifically determined, but apparently 

 indicates an Elephant allied to, or identical with, the present 

 species. 



M. 3089. Fragment of a right mandibular ramus, containing five 

 (Fig.) ridges of a well-worn true molar ; from the Pleistocene of
