This species is wholly unlike any other, fossil or recent, with 

 which I have been able to compare it. It seems to form an inter- 

 mediate link between the Gavials and true Crocodiles, for the snout, 

 though long and narrow, is gradually and not abruptly produced 

 from the head, and has probably been from eight to twelve inches 

 longer than it now is. 



This remarkably large and admirably preserved relic, was found 

 in the cretaceous limestone which overlies the ferruginous marl near 

 Vincentown, in New Jersey, and has been obligingly presented to 

 our Institution by General William Irick (on whose farm it was 

 discovered,) and William Whitman, Esq. of this city. These strata 

 of cretaceous limestone were first discovered and announced by me 

 in 1829; in which year I published an account of them, with a list 

 of their organic remains, as observed at Timber creek, in Gloucester 

 county.* Since that period I have continued my researches into 

 this interesting section of our geology, which I have subsequently 

 identified in two other localities in New Jersey, viz. Vincentown and 

 the vicinity of Salem, and also in South Carolina west of Charleston ; 

 at which latter place the fossils have been chiefly collected by Dr. 

 Ravenel, who is preparing for publication a description of several 

 species hitherto unknown. 



I obtained from Timber creek at my first visit, a fragment of the 

 jaw of a Crocodile with three teeth ; but the parts were not suf- 

 ficiently perfect to enable me to decide to which division of this class 

 of animals it pertained. Upon comparing it, however, with the spe-
