FAUNA ANTIQUA SIVALENSIS. 



Figs. 6 and 6 a. — Elephas Hysudricus. Lower jaw, left side, with 

 first true molar which has ten plates, with a small heel and front ridge. 

 It is excessively like Plate VII. fig. 11, which is the penultimate of E. 

 Hysudricus. The specimen is very remarkable as it is believed to have 

 come not from the Sewalik hills, but from the valley of the Nerbudda ; 

 the mineral condition, however, is very hard, unlike the Nerbudda 

 specimens. Presented by C. Frazer, Esq. — B.M. 



Length of molar, 8 - in. Width, 2 - 6 in. Height at 8th plate, 4*2 in. 



Plate XII. D. 



Figs. 1 and 1 a. — Elephas Namadicus. Beautiful specimen of lower 

 jaw, left side, containing the first true molar with thirteen ridges, and 

 a heel and front ridge, fifteen ridges in all. — B.M. 



Extreme length, 162 in. Height at alveolus, 6 - 3 in. Length of molar, 7"4 in. 

 Width, 2-2 in. 



Figs. 2 and 2 a. — E. Namadicus. Lower jaw, right side. This is 

 a little larger than the last specimen, and contains the first true molar 

 with about thirteen ridges. All these specimens show two highly- 

 placed mentary foramina. Part of the molar is concealed behind. A 

 portion of the third milk molar is seen in front. — B.M. 



Extreme length, 19 - 5 in. Height at alveolus, 6 - 4 in. Length of molar, 7'3 in. 

 Width, 2-5 in. Width of jaw behind, 6'4 in. 



Figs. 3 and 3 a. — E. Namadicus. Lower jaw, left side. This is a 

 most beautiful specimen, containing the second true molar. The 

 alveolus of the last tooth is shown behind. It contains about fifteen ' 

 plates, twelve to thirteen of which remain. The whole length of the 

 tooth is present. It narrows very much in front. N.B. — Another 

 specimen of same jaw, opposite side, not figured, is exactly similar. — 

 B.M.

Figs. 4 and 4 a. — Elephas antiquus. * Lower jaw, left side, with first

 also exactly alike. — B.M.
