ME. ST. GKEOEGE MIYAET ON THE SKELETON OF THE PEIMATES. 427 
Eig. 5. Scapula of Pithecia from the mounted specimen in the British Museum, showing 
the extremely small supraspinous fossa. 
Fig. 6. Scapula of Nycticebus tardigradus, from the skeleton No. 4634 a. in the Museum 
of the College of Surgeons. 
This shows the small size of the supraspinous fossa, the shortness of the 
acromion, and the concavity of the axillary margin. 
PLATE XII. 
Fig. 1. Scapula of Perodicticus, from a skeleton in the British Museum. 
Here the supraspinous fossa is large, the vertebral margin very convex, and 
the axillary one concave. 
Fig. 2. View of the glenoid surface of the same, showing the length of the coracoid 
process, and its divergence from the glenoid surface. 
Fig. 3. Clavicle of Mycetes. 
Fig. 4. Humerus of Cynocephalus, showing the strongly marked ridges, the great 
descent of the inner end of the trochlea ( t ), and the small projection of the 
external condyle ; also the great thickness of the shaft, the considerable ele- 
vation of the great tuberosity, &c. 
Fig. 5. Lower half of humerus of Mycetes, showing the descent of the inner condyle ( c ) 
to a level with the inner end of the trochlea (£). 
Fig. 6. Humerus of Indris, showing the very prominent border of the bicipital groove, 
the large and truncated inner condyle, the slight projection of the inner 
margin of the trochlea, &c. 
Fig. 7. Radius and ulna of Indris, showing the wide interval between the bones, their 
cylindrical form, small olecranon, &c.

of the Royal College of Surgeons. 
p. Subpubic groove. 
The tuberosity of the ischium rather approaches the human form. 
Fig. 2. Os innominatum of Indris, from the skeleton in the College of Surgeons 
Museum. 
s p. The enormous posterior inferior (inferior anterior of Man) spinous 
process. 
Fig. 3. Os innominatum of Loris gracilis, from the skeleton No. 4633 in the same col- 
lection. 
This shows at m the ridge which runs obliquely outside the ilium, and 
which appears to answer to the anterior margin of Man ; as also s p to his 
inferior anterior spinous process. 
t i represents the singularly man-like tuberosity of the ischium.
