DESCRIPTION OF PLATES. 17 
in the corresponding specimen in the Museum of the Asiatic Society 
of Bengal. 
Fig. 4.—Elephas Hysudricus. This fragment of skull, which is 
probably female, and is but very slightly concave on the forehead, 
yields very few good measurements. The figure is chiefly given for 
the form. It has two small tusk sheaths; the tusks are broken off 
near the base of the nucleus, and show only a thin plate. Only one 
orbital foramen, very large. This specimen is very remarkable in 
the molars having so few plates, only eight to the first true molar and 
no heel.—B.M. 
Length of penultimate molar, 5-2 in.; width, 2°3 in. The penultimate entirely 
in germ shows eleven plates. Extreme length of the fragment, 28-5in. Length 
from occiput to tip of nasals, 18-0 in.; width of nasal opening, 12-5 in.; width of 
brow across orbits, 21°6 in. Interval between the teeth in front, 2°1 in.; interval 
at niche of palate, 3°8 in.; diameter of the right tusk, 2°5 in. 
Puate XII. C. 
Figs. 1 and 1 a.—Hlephas Namadicus. A small fragment of lower 
jaw, with three plates of what is probably the first true molar.—B.M. 
Figs. 2 and 2 a.—Hlephas Namadicus. Lower jaw, left side. This 
specimen contains the third milk molar well worn and the first true 
molar in germ.—B.M. 
Extreme length, 12°56 in. Height at alveolus, 4:1, Thickness of jaw behind, 
4:0 in. Length of anterior molar, 5-2 in.; width, 1:8 in. Number of plates 
remaining, 7. 
Figs. 3 and 3 a.—H. Namadicus. Young lower jaw, right side, with 
third milk molar, which has ten ridges and a heel. The crimped 
character of Hlephas antiquus! is well shown. <A small vertebra is 
attached to the ramus.— B.M. 
Length of fragment, 11:0 in. Height at alveolus, 4:8 in. Thickness behind, 
4:0 in. Length of third milk molar, 5°5 in.; width, 1:9 in. 
Figs. 4 and 4 a.—E. Namadicus. Right lower jaw of adult, con- 
taining last molar with twenty plates and a heel. The specimen shows 
two mentary foramina. The broken coronoid portion of the ramus 
shelves more out than in L. antiquus,? and the mentary foramina are 
placed higher. Presented by C. Frazer, Esq.—B.M. 
Extreme length of fragment, 23°6 in. Height at alveolus, 9°2 in. Length of 
the molar partly concealed and chiselled, 14:7; width, 3:11 in. Width of jaw 
behind, 8:0 in. 
Figs. 5 and 5 a.—E. Namadicus. Adult lower jaw of large size. 
The specimen does not show the beak distinctly, and is more obtuse 
there than in #. antiquus.3 The number of outer mentary holes is 
uncertain, as in H. antiquus* there is no inner hole. Presented by 
C. Frazer, Esq., and described in Journ. Asiat. Soc.—B.M. 
Extreme length, right side, 20°5 in. Expansion of rami, 24° in. Height of jaw at 
beginning of alveolus, 10: in. Length of right molar, 14:in. Width, 3-7 in. Number 
of plates remaining about 15. Greatest width of jaw, 8°1 in.
