_ This skeleton is very interesting as being only the second 
species of the family of which any other part of the animal but 
the skull has been observed. 
i he form of the lower jaw gives a very peculiar appearance 
to the skeleton. The cervical vertebræ are united together 
by their bodies and large dorsal processes, the latter forming a 
thick conical process. The bodies of the dorsal vertebræ are 
very small, enlarging in size towards the tail; they are thirty- 
six in number. The four terminal caudal ones are very small, 
forming a kind of cylindrical process. There are eight chevron 
bones. The thoracic cavity is small. There are twelve ribs 
on each side. The dorsal processes of the first eighteen ver- 
tebræ have an anterior basal process, which becomes gradually 
smaller. - 
Krefft, who has sent me a more detailed photog of 
r 
the lower jaw, has not, unfortunately, sent one of the limbs.
