320 FOSSIL REPTILES. 



cated, and divided into two apophyses by a narrow emargina- 

 tion. This bone, M. Cuvier thinks, is probably a coracoid of 

 a saurian. Dr. Buckland was inclined to think it an iliuni. 



Another flat bone, widened on one side, and slender towards 

 its edge, seems to have been an ischion. 



The femur, like the teeth, exhibits a sort of mixture of the 

 characters of the monitor and the crocodile. It is arched in 

 two directions, being, at first, concave in front, and then be- 

 hind. Its articular head, directed forwards, has behind it a 

 compressed and rather salient trochanter. It thickens towards 

 the bottom, and is terminated there by two unequal articular 

 condyles. Within a little of the third of its height, it has, on 

 its two faces, a swelling like the one which is seen on the in- 

 ternal face in the crocodile. The femur of a monitor would 

 be less arched. The medullary cavity of this is wide and filled 

 with spath. 



Three long bones were taken from the same slate quarries, 

 the first of which Dr. Buckland regards as a metatarsian, but 

 M. Cuvier thinks that it more resembles a humerus, but one 

 very different from that of reptiles in general. Another may 

 be either a radius or a fibula. The third. Dr. Buckland 

 thinks, is probably a clavicle. If so, from its proportions, it 

 must have belonged to an animal fifty-five feet and upwards 

 in length. But it is very difficult to decide respecting these 

 bones. 



The vertebrae that remain resemble those of no living croco- 

 diles, monitors, or other lizards ; and they can only be com- 

 pared to the first of the Honfleur fossil crocodiles, or some 

 other fossil species of that genus. They are a third more in 

 length than in breadth. The annular part is united to them by 

 a very marked articulation, which approximates them more to 

 the crocodiles than the monitors. It is raised and hollowed 

 into a cavity as in the Honfleur species. Their body is a little 

 narrowed in the middle, but less so than in the crocodile of
