its upper part, and its anterior border is more convex than in the 

 domestic horse. In this respect the scapula of E. prjevalskii has 

 a close resemblance to that of the ass. The spine of the scapula 

 (spina scapulge), which runs down the outer surface, ends as in 

 the horse. It is remarkable that the coracoid process (processus 

 coracoideus) is only feebly developed, whereas, in the horse and 

 the ass it is larger. The following table shows the measurements 

 of the scapula : —

 from that of the other Equidce. on account of its notable thickness.
