The following bones, to No. 3639 inclusive, are parts of the same Giraffe as No. 3618: 



Hunterian. 



3621. The axis, or vertebra dentata. 



The posterior epiphysis of the centrum is wanting : the synchondrosal surface is concave. 

 The fore part of the ridge representing the transverse process is perforated by the vertebral 

 artery, and the fore part of the neurapophysis is perforated by the spinal nerve : there is a 

 long and sharp hypapophysial ridge. The length of this vertebra is eleven inches nine lines. 



3622. The sixth cervical vertebra. 



The epiphyses are wanting at both ends of the centrum, the front one of which is convex 

 and the hind one concave : a pair of hypapophysial ridges lead from the lower and hinder 

 angles of the centrum forwards to the lamelliform inferior processes. 



3623. A middle dorsal vertebra. 



The posterior epiphysis of the centrum is wanting. The metapophysis projects midway 

 between the diapophysis and the anterior zygagophysis. 



3624. A posterior dorsal vertebra. 



Both the epiphyses of the centrum are wanting. The metapophyses have nearly the same 

 position as in the preceding vertebra. 



3625. A pair of thoracic ribs. 



The head and tubercle are divided by a deep and narrow notch. 



3626. The left scapula. 



In its great length, as compared with its breadth, it approaches the typical form of the 

 bone, as a pleurapophysis. The coracoid is a low but large protuberance. The spine sub- 

 sides gradually at both ends, without a rudiment of an acromion. 



3627. The right humerus. 



The proximal epiphysis is still unconfluent. 



3G28. The right radius and ulna. 



The distal epiphyses are connate, but have not become confluent with their respective dia- 

 physes. Part of the slender shaft of the ulna is suppressed, or has blended with the lower 

 third of the radius, the rest of the ulna being free, or suturally united with the radius.
