of the arms, and fingers, more or less displaced. These several 

 parts are enumerated by Dr. Buckland as follows : 



"One cervical vertebra, f of an inch in length ; near this bone are 

 small cylindrical ossified tendons, resembling the tendons which run 

 parallel to the caudal vertebrae of rats. 



Dorsal and lumbar vertebrae, in a fragmentary state. 



Three caudal vertebrae. 



Two scapulae, or omoplates, long and narrow, as in crocodiles. 



Two coracoids, large, as in birds, for the support of the wings in flight. 



Sternum, broken and indistinct. 



Humeri. The right humerus and scapula are much displaced ; the 

 left humerus, and other bones of the left wing , are nearly in their natural 

 j uxta-position. 



Fore-arm : there are no traces of an ulna. 



Carpus : in the left, four bones are well preserved, three in contact 

 with the radius, the fourth with the largest metacarpal. The right 

 carpal bones are all dispersed. 



Metacarpals ; first, second, and third of the right hand, and also of 

 the left ; and the fourth of each hand supporting the respective wing- 

 fingers. 



Three fingers of the left hand, terminating in long claws; there are 

 two phalanges in the first, three in the second, and four in the third 

 finger, as in crocodiles. 



All the bones of the first and third fingers of the right hand. 



First bone of the fourth or wing-finger ; there is no vestige of a fifth 

 finger. 



Pelvis : the three bones of the right side, viz., the ilium, ischiuni, 

 and pubis, are very distinct. 



The two femora ; the right one displaced. 



The tibiae ; the left one compressed : there are no traces of fibulee. 



Tarsus, but faintly indicated. 



Metatarsus ; four of the left foot distinct and undisturbed, their 

 under aspect being exposed. 



Phalanges of the left toes, the claws wanting. 



Toes of the right foot, much displaced ; one claw only remains. 



The length of the foot, and of the tibia and femur, shows 

 that the animal must have stood firmly on the ground, on 

 which, probably, with its wings folded, it moved after the 

 manner of birds. It could, perhaps, also perch on trees, and 

 cling to their branches by means of its feet and toes, like birds 

 and lizards." l
