The slceleton is very similar to that of the preceding species, but 

 less compressed and elevated ; it differs chiefly in the following points : 

 the interior of the lateral ridges on the upper surface of the skull is 

 scarcely visible ; the mandibula is very low. I do not find more than 

 nine abdominal vertebrae, one of the anterior ones not being developed, 

 apparently owing to the short longitudinal diameter of this portion ; 

 its length is to that of the caudal portion as 1 : 2-1. The posterior 

 intemeurals and interhsemals are feeble, and leave free spaces between 

 them. The first hasmal and interhaemal are also united to a strong 

 bone, but it is much shorter than the vertebral column ; it is infe- 

 riorly dilated into a triangular plate with a slight ridge. The ribs 

 are of moderate strength and length.
