30 MESSRS. MURIE AND MIVART ON THE 
Meckel observes that it is large in the Makis (Lemurs), and is inserted into the second 
fifth of the humerus’. 
It is represented by Cuvier in Lemur varius (pl. 68. fig. 2, and pl. 69. fig. 1, 0) and 
in Loris gracilis (pl. 67. fig. 1, 0). 
Shown in Galago crassicaudatus (PI. II. fig. 3, Pl. Ill. figs. 5, 6, 7, and Pl. IV. 
figs. 13 & 14, T.ma.), but the surface is not so highly tendinous in this species as in 
L. catta. 
In Tarsius? it is as in L. catta, except, of course, proportionally smaller. 
Turns mivor.—This is a very small and inconspicuous muscle ; and there is therefore 
the less wonder that it should have escaped Meckel’s* and Cuvier’s* observation. It 
arises from the lower (anterior) half of the axillary border of the scapula, its origin 
extending rather further up (back) than, but not quite so far downwards (forwards) as, 
that of the long head of the triceps. It is inserted into the lower part of the radial 
tuberosity. 
In Galago crassicaudatus this muscle (PI. III. fig. 6, and PL. IV. fig. 13, T. mi.) is of 
moderate size, and is attached quite to the neck of the scapula, and slightly covered by 
the infraspinatus. , 
We found in Galago allenii the teres minor to be comparatively larger than in Lemur 
catta; its fibres also arose more superficially upon the dorsum of the infraspinatus, 
being partly attached to the lower border of the spine of the scapula, chiefly about its 
middle; but it had a similar insertion. 
Nycticebus tardigradus, like Lemur catta, has it small. 
Burmeister says that in Tarsius it is present, but weak. 
In Cheiromys, Owen ° mentions that it is not much inferior in size to the teres major ; 
but in our dissection we have found it very much smaller than the teres major, yet very 
distinct and quite in the condition it presents in Lemur catta. As Professor Owen takes 
no notice of the infraspinatus, and as the teres minor is pretty closely connected with the 
latter muscle, he has probably mistaken the teres minor for it. 
c. Humeral Region (posterior and anterior). 
Tricrps.—This muscle is very large and complex in L. catia, not only consisting of 
all the parts found in Man, but one of the heads described as single in him being here 
differentiated into four more or less distinct parts. 
1. The long head is very tendinous at its origin, which occupies about half an inch 
at the lower (anterior) part of the axillary margin of the scapula. 
2. The outer head arises from the postero-outer portion of the head of the humerus, 
beside the insertion of the teres minor.
