Owen says — "The subscapnlaris is a narrow muscle and 

 narrower in reality than at first sight it appears to be, since the 

 supraspinatus from the inflection of the spiue and acromion, arises 

 from the same aspect of the scapula, and appears to form the 

 anterior fasciculus of the subscapnlaris." 



CouES, as stated above, describes for the subscapularis what is 

 really teres minor, while under the heading of teres major we find 

 a description of the subscapularis. Thus in the description of the 

 teres major we have the following : — " the upper portion is still 

 larger and has more extensive and complicated origin from both 

 sides of the scapula, which is thus, as it were, embraced by this 

 muscle. The outer origin is from the po.stero-external aspect of 

 the scapula, and from the origin of the lower teres to that of the 

 scapular head of the triceps ; the inner origin is thinner and more 

 extensive and fleshy from the whole surface of bone between the 

 insertions of the two digitate sets of levatores scapulae. 

 It is inserted much higher up, in immediate relation with the 

 shoulder joint, into the posterior tubercle of the humerus, along- 

 side the insertion of the muscle above called subscapnlaris [teres 

 minor]. N.B. — Its tendon contains an articular sesamoid bone." 



. Leche gives, for a description of the subscapularis, Cones' 

 description of the teres minor ; while under the heading " teres 

 major," we get Coues' description of the second jDait of the teres 

 major, i.e., of the subscapularis proper. 



Meckel says — " Subscapularis, scapulte ipsius facie interna ad 

 ossiculum, summo tuberi interno ossis humeri nonnisi capsula 

 junctiim tendit." Again Meckel describes, as the second part of 

 the teres major, what is really part of the subscapularis. "Alter, 

 ab eo tectus (i.e., teres major), a dimidio posteriore scapulse super- 

 ficiei externae ortus, ante praecedentem ad faciem posticam ossis 

 humeri tendit, infra caput ei insertum." 



CuviER and Laurillaud figure (in P\. 268, fig. in.) this muscle 

 under the name of " sous-scapulaire (scapulo-trochinien)," the
