each side along at least 8 inches of the jaw; 
in the middle of the jaw there appear to be 
7 teeth in the space of an inch. 
4 caudal vertebra of Pterodactyl us macrurus, from 
Langton, near Swanage. Purbeck beds. This 
vertebra is 5 inches long, and conforms in 
general structure to the plan of caudal ver¬ 
tebrae of the Ornitliosaurians from the Cam¬ 
bridge Greensand, differing chiefly in being 
narrower at the articular ends. The largest 
caudal vertebra hitherto known is 1^ inch 
long, figured by Prof. Owen in his account of 
Pterodactylus simus. 
5 phalange of wing finger of a small Pterodactyle 
from the middle Purbeck of Durlstone bay.
