either the acromion or sternum. In the Felidce it is slender 

 and curved, being longer than in any other members of the 

 order. In the CajiidcE it is very short, and rather broad and 

 flat. In most of the Ursidce it is absent. 



In the Seals both acromion and coracoid are much re- 

 duced, but the latter is a distinct bone in young animals, 

 and forms a considerable part of the glenoid cavity. The 

 whole scapula is much curved backwards, being almost 

 sickle-shaped, and the suprascapular epiphysis is very large 

 and slowly ossified. 



In the Eared Seals (Ofan'a) the scapula has a different 

 form, the prescapular fossa being very much larger than the 

 posterior, and with a strong vertical ridge, parallel to the spine. 



None of the Pinnipedia have clavicles.

Order Cetacea. — In the true Dolphins and nearly all the 

 Odoutoceti the scapula is usually very broad and flat, or fan- 

 shaped. (See Fig. 76.) The prescapular fossa iaf) is ex- 

 tremely reduced ; the acromion {a) is a long flat process.
