upon the dorsum of the Infraspinatus, partly attached to the 

 lower border of the spine of the scapula. 



The muscle in Nycticehus tardigradus is small and has the 

 same general arrangement as in Lemur. 



Burmeister (6, p. 48, tab. 3, fig. 1, No. 10) says that it is pres- 

 ent in Tarsius spectrum, but very weak. 



Murie and Mivart (1, p. 30) found the muscle in Cheiromys 

 small, but very distinct from the Teres major. 



It is quite evident, therefore, that the Teres minor is gener 

 alh^ present in the Lemuroidea, although usually of small size 



D. M. Teres major. 

 (PI. XXIX to XXXIII. incl.) 



This is a very broad and strong muscle. 



Origin : Medial third of axillary margin of the scapula; me- 

 dial part of dorsal surface of axillary border, between the Infra- 

 spinatus and Subscapularis, and from the Infraspinatus fascia. 



Insertion: The fibres spread out toward the insertion, form- 

 ing a flat muscular sheet which becomes tendinous onl}- just be- 

 fore the insertion into the prominent internal bicipital ridge and 

 floor of the bicipital groove. 



The tendon of the Latissimus dorsi lies upon the ventral sur- 

 face of the Teres major tendon of insertion, entirelj' free from 

 the same, covering only the middle third of the Teres tendon, a 

 large single bursa being placed between the tendons. 



Murie and Mivart (1, p. 29, 30) describe the muscle in Lemur 

 catta as arising '' from the superior half of the axillary border 

 of the Scapula, and from the flat surface at the posterior end of 

 that border." The muscle broadens out greatly in descending 

 and has a glistening tendinous outer surface. 



The insertion, which is almost 1 inch wide, is into the inner 

 margin of the bicipital groove, separating the two portions of 

 the Coracobrachialis. 



Meckel (Anat. Comp. Yol. YI., p. 262) describes the muscle 

 as large in the Lemurs, with an insertion into the second fifth 

 of the humerus. 



Cuvier (11, PI. LXYIIL, fig. 2, and PI. LXIX., fig. 1, o) 

 figures it in Lemur varius and (PI. LXYII., fig. 1, o) in Loris 

 gracilis. 



Burmeister (6, p. 48, tab. 3, fig. 2, 12) describes it in Tarsius, 

 having the same arrangement as in Lemur. 



Murie and Mivart (j, PL II., fig. 3; Pi. III., figs. 5, 6, 7, and 

 PI. lY., figs. 13 and 14, T. ma.) figure the muscle in Galago 

 crassicaudatus.
