MONOGRAPH 



ON 



THE FOSSIL REPTILIA 



THE CRETACEOUS FORMATIONS, 



Order— PTEROSAURIA, Owen. 

 Genus — Pterodactylus, Cuvier. 



In the 'Monograph of the Fossil Reptiha of the Chalk Formations,' p. 103,* 

 the occurrence of remains of a large Pterodactyle in the Green-sand formation near 

 Cambridge, was noticed, and portions of the wing-bones were figured in Tab. XXXII, 

 figs. 6— 8.t 



The Woodwardian Museum of the University of Cambridge has subsequently 

 been enriched by successive acquisitions of fossils, obtained, chiefly through the exer- 

 tions of Lucas Barrett, Esq., F.G.S., from the same stratum of ' Upper Green- 

 sand,' near Cambridge, where I had the opportunity of inspecting them last year. 

 All those belonging to the Pterosauria have since been liberally transmitted to me by 

 my friend Professor Sedgwick for description and illustration in the Monographs of 

 the Palceontographical Society,-and I have subsequently received a few highly interest- 

 ing additional examples of Pterodactyle remains from sources which will be duly 

 acknowledged in the sequel.
