TO THE 



MONOGRAPH 



ON 



THE FOSSIL REPTILIA 



OF 



THE CBETACEOUS FORMATIONS. 



Order— PTEROSAURIA, Owen. 

 Genus — Pterodactylus, Cuvier. 



In former monographs on the fossil reptilia of the Upper Green-sand of 

 Cambridgeshire,* I have described, figured, or referred to, parts of a Pterodactyle, 

 from an individual surpassing in size that to which the portions of upper and 

 lower jawf belonged on which the species dedicated to Professor Sedgwick 

 was founded. Such fossil evidences of more gigantic flying reptiles, showing 

 no better distinctive characters, 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 

 Pterodactyle, distinct, in regard to the form of the skull, from any previously 

 known, and one which, assuming that the portion of upper jaw of Pterodactylus 

 Sedgwichii (Tab. I, fig. 1, 'Monograph' of 1857) belonged to a full-grown 

 specimen, must have acquired at least double the dimensions of that species.
