﻿WEALDEN FORMATIONS.

Crocodiles is divided by a pterygoid partition ; although Cuvier makes the absence of 

 this division, or inconspicuousness of the septum, a character of the skull of proccelian 

 Gavials. 1 Hylaochampsa may show this partition in an exaggerated degree, and the 

 orifices s, s, and not the orifice <?, would be the hinder nostril. 



Whatever alternative may commend itself to competent Palaeontologists, the palatal 

 characters which distinguish Hylceochampsa from all other known Reptiles, recent or fossil, 

 are unaffected. 



I have had no opportunity of studying the palatal characters in Goniop/iolis, 

 Suchosaurus, or any other Wealden Crocodile than the subject of the present Monograph.
