DESCRIPTION OF PLATES. 37 
front at diasteme, and high with an edge; ascending ramus is inclined 
forward and does not shelve out. Molar has seven or eight ridges re- 
maining, but is imperfect in front; enamel very much crimped (Vide 
Plate XXV. A. fig. 2).—B.M. 
Extreme length of jaw, 19°3 in. Height to alveolus, 8° in. Thickness in front, 
4-1 in. Thickness behind, 6°3 in. Length of right molar, 8-9 in. Width at 
middle, 4°7 in. 
Figs. 2 and 2 a.—Elephas bombifrons (Fale. and Caut.). From the 
Sewalik hills. Fragment of lower jaw, showing the united symphysis, 
parallel rami, and three large mentary foramina on outside. Only a 
fragment of last molar seen on both sides.—B.M. 
Extreme length, 17°3 in. Height to alveolus, 7°8 in. Width of jaw in front, 
3°6 in. Width of jaw behind, 6:1 in. 
Figs. 3 and 3 a.—E. bombifrons. Magnificent specimen of lower 
jaw; fault in jaw; two large mentary foramina; beak very thick ; 
right molar has nine ridges and a heel; enamel very thick; hardly any 
cement.—B.M. 
Extreme length of jaw, 23°6 in. Height to alveolar margin, 9° in. Thickness 
in front, 4°2 in. Thickness behind, 8°3 in. Length of right molar, 129 in. 
Greatest width at fifth ridge, 4:4 in. 
Figs. 4 and 4 a.—Elephas insignis. Lower jaw, partly distorted by 
pressure, and containing two molars on either side. The anterior 
(first true) molar is entire, though mutilated, and has seven ridges and 
a large heel. The back (second) molar is fragmentary.—B.M. 
Extreme length of Jaw, 15° in. Height to alveolus, 5°8 in. Thickness in front, 
3°) in. Thickness behind, 5°5 in. Length of front molar, left side, 6-5 in. Width 
at middle, 2°5 in.

Figs. 1 and 1 a.—Elephas Ganesa (Fale. and Caut.). Fragment of 
lower jaw, thick behind, with last lower molar, showing seven ridges 
and a heel, and great crimping, but: no characteristic feature.—B.M. 
Length of right molar, 8°8 in. Greatest width, 3°8 in. 
Figs. 2 and 2 a.—H. Ganesa. Fragment of lower jaw, very old, 
with last molar much worn. Resembles Plate XXYV. fig. 1—B.M. 
Height of jaw at alveolus, 7°8 in. Length of right molar, 10-2 in. Width, 
4: in. 
Figs. 3 and 3 a.—E. Ganesa. A dumpy, small-sized lower jaw, 
with imperfect molar ;_ seven ridges remaining ; the back ridges curved 
and much crimped. 
Length of molar, 8-4 in. Width behind, 3:8 in. Width in front, 3°4 in. 
Figs. 4 and 4 a—E. Ganesa. This little lower jaw is very remark- 
able in being high and narrow; the ascending ramus is much bent 
forward. It contains three teeth, one in front worn out; a second with 
seven ridges and a heel, and a third in germ.—B.M. 
Extreme length of jaw, 18'4in. Height to alveolus, 6-in. Height at front tooth, 
2-5 in. Height behind, 4: in. Length of ramus (antero-post.), 8°7 in. Length 
of front tooth, 2°56 in. Length of second tooth, 5:2 in.; width in front, 2° in. ; 
width behind, 2:3 in. 
Figs. 5 and 5 a.—E. Ganesa. Angle of lower jaw, left side, with 
portions of ascending and horizontal rami, and posterior five and a half 
ridges of last irue molar—B.M. 
Length of fragment of molar, 7-in. Width, 3°9. in.
