WEALDEN CROCODILES. 435 



just cited. The teeth of the Suchosaur also present a character which does not exist 

 in tlie teeth of the Megalosaur, and is not attnbuted by Cuvier,* to tliose of the 

 Crocodile d'Argenton. The sides of the crown are traversed by a few longitudinal, 

 parallel ridges, with regular intervals of about one line, in a crown of a tooth one 

 inch and a half in length ; these ridges subside before they reach the apex of the 

 tooth, and more rapidly at the convex than at the concave side of the crown. 



Hitherto these teeth have not been found so associated with any part of the 

 skeleton of the same species as to yield unequivocally further characters of the 

 present extinct Crocodilian. From the above-mentioned well-marked differences 

 between these teeth and those of all other known species, I regarded the extinct 

 Crocodile as forming the type of a distinct genus and species, and proposed for it 

 the term Suchosaums culfridens.f
