branches is longer than in any other fossil reptile, longer even 

 than in the gavial. It extends more than five inches beyond the 

 condyle. Seen sideways, the bone is formed so as to rest on a flat 

 surface, and it rises gently from near the end to a low coronoid 

 convexity, without the lacuna below which occurs in crocodiles. 



The expansion of the branches of the lower jaw is greater in 

 the specimen figured in Diagram XLIV. than is usual. It is the 

 largest complete specimen known to me, and this extreme width, 

 if not occasioned by pressure, may be due to age, as seems to be 

 the case with the Indian gavial. This specimen is 36-3 inches 

 long, of which the symphysial part is 16-7, and the breadth over 

 the condyles 137.

The jaws are here viewed from above to shew the almost circular nasal cavity, and 

 the intermaxillary suture, and the lateral prominence of the lower jaw teeth, opposite 

 the diastema of the upper jaw. 



The teeth, thirty-one or thirty-two^ on each side in each jaw, 

 may be characterized as incisors two, separated and directed 

 forward in the lower jaw, close set and tending downward in the 

 upper; captatorial or quasi-canines, two, large, usually only one 

 fully exhibited, the other broken off or fallen out ; twenty-seven 

 or twenty-eight nearly similar and of equal size, except the six
