142—44 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
diate stage of wear, and is somewhat damaged ; as far as can he judged, it appears to 
have had the ‘ costoe 5 hut slightly developed, as in Ey d aspitheriym ; its crown seems, 
however, lower ; and the tooth is marked hy the great development of the ‘ lobe * 
of the e accessory column.’ In the following table the dimensions of this specimen 
are compared with the corresponding dimensions of those of four other members of 
the family, taken from the foregoing memoir : — 
Camelopardalis. 
Bramatherium. 
Hydasp. megaceph. 
Hydasp. grande. 
SiYatherium.

These dimensions show that the hinder part of the lower jaw of Bramatherium 
was more slender than that of Eydaspitherium, and thereby approached the giraffe 
and the visnuthere. The middle part of the jaw of Bramatherium, of which the 
dimensions are given on page 61 of the first volume of this work, shows a smaller 
depth than the jaw of E. megacephalum, and we may therefore conclude that the 
lower jaw of Bramatherium was slighter than that of the narrow-jawed hydaspi- 
there, to which, however, the teeth most nearly approximate. There is no ‘ cin- 
gulum 5 in the lower molar of Bramatherium , nor any tubercles in any of the val- 
leys on the outer side.
