[Plate XXIL] 



The genus Ornithocheirus was founded by Seeley on numerous 

 fragments of jaws and odd bones of Pterodactyls from tlie 

 Cambridge Greensand, preserved in the Woodwardian (now

 the specimens are more or less water-worn. The most perfect 

 are a humerus, femur, and several carpal bones. The first 

 character laid down as pertaining to the genus * was " no 

 teeth anterior to the j)alate," which, later f, was negatived

 Ornithocheirus was originated to include three deep club- 

 shaped jaws of the type of Pterodactylns simns, Owen, and 

 Ptenodactylus, for tlie spear-shaped jaws of the tyjie of 

 Pterodactijlus sedgivicki, Owen. Hence the definition of the
