DESCRIPTION OF PLATES. 33 
very divergent rami behind; diastemal edges very sharp; two outer 
mentary foramina on right side. The front tooth much worn ; has five 
ridges and a heel; the last’ tooth has eight ridges. Nothing else like 
this in the collection.—B.M. 
Extreme length of jaw, 18°5 in. Height at alveolus, 8:5 in. Width of jaw in 
front, 4° in. Width of jaw behind, 5:8 in.! Length of front tooth 5-lin. Width, 
2:7 in. Length of last tooth, 9°3 in. Width, 3-2 in. 
Figs. 2 and 2 a.—Klephas Ganesa. Portion of lower jaw with left 
penultimate lower molar. The jaw in this specimen is also very high 
and narrow in front, and low behind. The tooth has seven ridges 
and a heel. Behind it is seen a portion of the last molar.—B.M. 
Length of fragment, 14:5 in. Height at alveolus, 8°3in. Height behind, 5:8 in. 
Width in front, 3°3in. Width behind, 6°6in. Length of molar, 9°2in. Width at 
back, 3:in. 
Fig. 3.—EHlephas insignis. Fine specimen of lower jaw, including 
ascending ramus. ‘Two outer mentary foramina. Second and third ? 
true molars. 
Figs. 4 and4 a.—H#. insignis. Fragment of anterior portion of lower 
jaw. Is the only specimen that shows a beak entire to the tip. Is 
very like the large specimen containing a molar with great number of 
plates (Vide Plate XVIII. A. fig. 3).—B.M. 
Figs. 5 and 5 a.—E. insignis. Fragment of lower jaw with last 
molar, imperfect. The latter has eight plates remaining ; seven denticles 
to the second (distinct) ridge. 
Length of fragment, 16-in. Length of eight plates of last molar, 8-1 im. Width 
in front, 3°lin. Width behind, 3°65 in. 
Fig. 6.—E. insignis? Fragment of lower jaw with second (third ?) 
true molar. The plates show seven to eight points. This is the 
specimen described by Clift in the Geological Transactions. It is very 
like E. insignis. It is also represented in Plate XX. figs. 6 and 6 a.— 
Geol. Soc. Museum. 
Length of fragment, 19°in. Height at alveolus, 6-6 in. Length of molar, 12: in. 
Width in front, 3°2in. Width in the middle, 3°6in. Length of fragment of 
anterior tooth, 4°2in. Width, 2°65 in. 
Figs. 7 and 7 a.—E. insignis. Fragment of lower jaw, right side, 
with first true molar nearly worn out, and six ridges of second molar. 
The plates are very high and there is much cement. The teeth are 
very broad in relation to the jaw, as compared with #. Ganesa in fig. 1. 
This is a beautiful specimen from Baker’s collection.—B.M. 
Length, 14-7in. Height, 7-7in. Width in front, 3°5in. Width behind, 6-7 in. 
Length of front molar, 4°6in. Width, 2°7in. Length of back fragment, 5:3 in, 
Width, 3 in. e 
PuateE XXI. 
Elephas Ganesa (Fale. and Caut.). From the Sewalik hills, in Colonel 
Baker’s collection. Large skull, with fragment of left incisive in situ, 
and corresponding fragment of right incisive detached. The incisive 
alveoli are remarkably elongated, as in H. primigenius. The plane of 
the incisives is continuous with that of the frontal, but with a tendency 
to obliquity forwards. The skull is very imperfect on right side. PI. 
XXI. gives a front view one-fifth of the natural size, and Pl. XXII. figs. 1 
and 2, give a lateral and palate view of the same skull. Compare with 
skull of H. insignis, Pl. XV.—B.M. The dimensions are as follows :—
