18 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 EZ. 
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, Hsq.—B.M.
