436 BRITISH FOSSIL REPTILES. 



Order— PlWi2 OS A TIBIA. 



SUPPLEMENT No. II. 

 PTERODACTYLES OF THE CRETACEOUS FORMATIONS. 



Genus — Pterodactylus, Cuvier. 



In the first supplement to the present order, on the Pterodactyles of the 

 Upper Green-sand of Cambridgeshire, I described,* figured,! or referred to, 

 parts of a Pterodactyle from an individual surpassing in size that to which the 

 portions of upper and lower javv| belonged on which the species dedicated 

 to Professor Sedgwick was founded. Such fossil evidences of more gigantic 

 flying reptiles, showing no better distinctive characters than size, were deemed, 

 probably, to belong to the Pterodactylus Sedgwickii, the then largest known species 

 of the genus. 



I am now, however, enabled to adduce, from the more recently acquired 

 additions to the Woodwardian Museum at Cambridge, supplied to me by the same 

 unfailing liberality of the eloquent Professor, evidences of a much larger Ptero- 

 dactyle, distinct, in regard to the form of the skull, from any previously known, and 

 one which, assuming that the portion of upper jaw of Fterodactylus Sed^tvickii (PI. 

 7, fig. 1) belonged to a full-grown specimen, must have acquired at least double the 

 dimensions of that species.
