THE MUSCLES OF THE UPPER EXTREMITY. 10 1 



case in tlie Raven and many otlier birds. Any way we 

 may regard it, however, the fact still remains that in 

 many vertebrates, we have a muscle that passes from 

 the middle outer surfaces of some of the leading ribs, 

 to become attached to some part of the shoulder-girdle, or 

 scapular apparatus, and that this muscle is an important 

 one in inspiration. We may call it the pec^^07'(x/^s 

 minor, or the thoraco-scapularis, as I have in the present 

 instance, as we may please.

 powerful of the muscles in the Corviche, and is well 



^ See No. 62 of the present memoir in this connection (the teres 

 minor), and the muscle here described appears to be the I. {suhscap. 

 externus) of Fiirbringer and Gadow, or in other words, as near as 

 I can make it out, my teres minor + (my) suhscapularis = the 

 suhscapularis (with internal and external part) of Fiirbringer. 

 Gadow (Bronn's Klassen, vi. Band, pp. 240, 241) presents us with 

 the following valuable study of the subject : —
