40 FAUNA ANTIQUA SIVALENSIS. 
ridges worn but the last; the two first worn out; a long sloping 
diasteme ; two outer mentary foramina.—B.M. 
Height of jaw to alveolus, 7-in. Thickness in front, 3°4in. Thickness behind, 
6°in. Length of molar, 6°4in. Width in front, 2°3in. Width behind, 2-9 in, 
Figs. 3 and 3a.—E. bombifrons. Portion of lower jaw, left side, 
with one large outer mentary foramen, and penultimate true molar, 
showing 7 ridges and a large heel.—B.M. 
Extreme length of fragment of jaw, 15°in. Height to alveolus, 7°3in. Length 
of molar, 85 in., Width in front, 2°8 in. Width behind, 3-2 in. 
Figs. 4 and 4 .a.—E. bombifrons. Fine specimen of anterior portion 
of lower jaw, both rami with symphysis. Contains the penultimate 
true molar of either side, with 7 ridges and a heel. Shows also the 
commencement of the last tooth behind, and proves the tooth (fig. 2) 
to be the first true molar. Jaw is deficient on both sides behind the 
penultimate.—B.M. 
Length of fragment, 14:3 in. Height to alveolus, 7: in. Thickness behind, 7: in. 
Interval between rami in front, 2°7 in. Interval behind, 3°3in. Length of right 
molar, 8'in. Width in front, 2°9in. Greatest width, 3°4 in. 
Fig. 5.—E. bombifrons ? Fragment of molar, from lower jaw, right 
side, with four ridges.—B.M. 
Length, 5°8in. Width, 4°5 in. 
Fig. 6.—E. bombifrons ? Fragment of molar with three ridges and 
a heel. ‘ Doubtful what figs. 5 and 6 are.—H.F. 
Length, 4°4in. Width, 4°65 in. 
Figs. 7 and 7 a.—E. bombifrons. Portion of lower jaw, with molar 
showing 7 ridges, counting the last; no heel; another tooth in germ 
behind; is apparently the first true molar, with the second, or penul- 
timate, coming behind it.—B.M. 
Length of anterior molar, 65in. Width, 2°7 in. 
Figs. 8 and 8a.—E. bombifrons. Lower jaw, right side, of a small 
variety, but old. It is figured chiefly for its small size. The tooth is 
certainly the last molar ; it is wide behind and very thick; the discs of 
wear are peculiar.—Specimen in Geol. Soc. Museum. 
Height of jaw to alveolus, 7°5in. Width behind, 6°5 in. Width in front, 4°5 in. 
Length of tooth, 7°8in. Width behind, 3: in. 
PrAth SOC: 
Figs. 1 and 1 a.—Elephas insignis. Fragment of anterior half of 
second milk molar, of left lower jaw, with two ridges and a front talon. 
Length of fragment, 1-7 in. Extreme width, 1°4in. Height, 1-2 in. 
Figs. 2 and 2. a.—Elephas Ganesa. Fragment of lower jaw, right 
side, with the third milk molar entire, presenting 7 ridges and a 
heel. 
Length, 46 in. Width in front, 1-4in. Width behind, 2-2 in. 
Fig. 3.—E. Ganesa. Fragment of lower jaw, with three molars 
(second and third milk, and posterior 5 ridges of first true). 
Figs. 4 and 4 a.—EH. Ganesa. Fragment of lower jaw, right side, 
with fifth or penultimate molar, presenting 8 ridges. 
Length, 7:25in. Width in front, 3-1lin, Width behind, 2:9 in.
