It will thus be seen that the determinations here adopted 

 depend mainly (1) on the interpretation of the homologies of 

 the elements with which the pectoral limbs are articulated, and 

 (2) on the application of the term "coracoid." The name 

 " coracoid," originally applied to the process so called in the 

 human scapula, and subsequently extended to the independent 

 element homologous Avith it in birds and other vertebrates, has 

 been more especially retained (e. g. by Parker in mammals 

 &c.) for the region including the glenoid cavity. On the 

 assumption that tliis may be preferred by most zootomists, the 

 preceding terms have been applied. But if the name should 

 be restricted to the proximal element nearest the glenoid 



* The name scapula might have been retained for this element, as it i.s 

 (if the views here maintained are correct) homologous with the entire sca- 

 pula of man, less the coracoid and glenoid elements ; but the restricted 

 meaning has been so universally adopt:^d, that it would be inexpedient 

 now to extend the word.
