 the Siwalik Formation of India, is a still larger and more 

 stoutly built animal, with a comparatively short and broad 

 skull, which bears two pairs of bony prominences (fig. 210). 

 The hinder appendages are much the larger, and are placed 

 just above the occiput probably on the parietal bones. They 

 are somewhat expanded and flattened (palmated), with a few

 frontals, from which they are clearly separated by suture in the 

 type specimen. The greater part of the skeleton has been 

 identified with much probability of correctness ; and a hornless 

 skull from the Siwalik Formation has been supposed to belong
