M. 2892. An imperfect first or second lower true molar, in a well- 

 worn condition ; from Burma. 



Presented by Col. Burney. 



The following specimen may perhaps belong to this species. 



M. 2886. Tho germ of a tooth which appears to be a third left lower 



(Fig.} premolar ; from the Siwalik Hills. Figured by Falconer 



and Cautley, op. cit. pi. xl. figs. 1, 1 a, as penultimate upper 



milk-molar. Cautley Collection. Presented, 1842. 



The following specimen is not specifically determined. 



46922. A much-worn (fourth ?) right upper milk-molar, with three 

 ridges and a large hind talon; from the Red Crag of 

 Woodbridge, Suffolk. Purchased, 1875. 



Genus ELEPHAS, Linn. 1 

 Including tttegodon, Loxodon, and Euelephas, Falconer 2 . 



Dentition: Usually I. J, C. J, Mm. |, M. |. The upper incisors 

 (which are preceded by milk-teeth) are usually large, and are devoid 

 of enamel except on the unworn apex. Lower incisors are apparently 

 always absent, and preinolars are known in only two species ; the 

 mandibular syrnphysis is always short, and frequently terminates in a 

 deflected spout-like channel. The ridges of the cheek-teeth are always 

 entire, and there is usually no trace of a median longitudinal cleft 

 on their crowns ; cement is always present in the valleys, but its 

 amount, as well as the relative height of the ridges, varies greatly 

 in different species. The number of ridges in the " intermediate " 

 molars appears to be never less than five, and, except in some of the 

 more generalized forms, is not isomerous throughout the series ; 

 the number of ridges in m. 3 is never less than seven, and may 

 reach to twenty-four. The plane of wear of the crowns of the 

 teeth of all the species except E. clifti is either nearly horizontal, or 

 the inner side of the upper teeth and the outer side of the lower 

 is the higher. There are never more than one or portions of two 

 cheek-teeth in use at any one time ; and all the teeth succeed one 

 another in the arc of a circle. The cranium is more vaulted than 

 is usually the case in Mastodon.

 subgenera, but ranked as genera by many later writers. The name Loxodon 

 is preoccupied by a genus of Sharks.
