Ornithochirus cuvieri (Bowerbank '). 



Syn. Pterodactylus cuvieri, Bowerbank 2 . 

 Coloborliynchus cuvieri, Owen 3 . 



Referred to this genus by Seeley (' Ornithosauria,' p. 113), by 

 whom it is provisionally recorded from the Cambridge Greensand. 

 Fully equal in size to the preceding species, but with the rostrum 

 shorter and thicker, and the teeth larger and less numerous, and 

 characterized by a marked lateral compression. The limb-bones 

 referred by Owen to this species are regarded as indicating an 

 expanse of wing of not less than 18 feet. 



Hob. Europe (England). 



39409. The greater portion of the cranial rostrum, showing the

 teeth ; from the Lower Chalk of Burham, Kent. This 

 specimen is the type, and is figured by Bowerbank in 

 the ' Proc. Zool. Soc' 1851, pi. iv. (lettered longirostris), 

 and also by Owen in his ' Cretaceous Heptilia ' (Mon. Pal. 

 Soc), pi. xxviii. figs. 1-7.
