two other secondary branches for the American Apes. It then bifurcates to symbolize 
the Simiinse and lower Simiidge. The secondary branch for the Cebidse gives off a very 
distinct twig to represent Ateles, and Lagothrix and Mycetes are also special forms. The 
secondary branch, standing for the lower Simiidse, gives off a twig for the Semnopithecinse, 
which is parallel to that for Ateles. That for the Simiinse gives off twigs (for Tro- 
glodytes) which approximate in direction to that followed by the branch representing 
Man. It then gives off another twig (for Hylobates) and culminates in Simia. 
The second main branch gives off, almost from its starting-point, and on the side next 
the higher Primates, a secondary branch to represent the Nycticebinse. Some con- 
siderable distance higher up, on the same side, another twig stands for the Indrisinse, 
while the branch itself culminates in Lemur, but gives off twigs for Galago and 
Cheiromys respectively, while almost from the base of its outer side, and diverging 
widely from the branches and twigs representing all other Primates, springs a twig 
symbolizing the very anomalous genus Tarsius ; a form, as we have seen, as distinct in 
limb structure from the rest of the Order as is the genus Homo. 
Thus the detailed examination of the appendicular skeleton of all Primates gives 
results not destitute of zoological value ; but its main interest consists in the bearing it 
has upon the skeleton of Man, the characters of which can, I think, be more fully and 
correctly appreciated after such a comparison than when it is contrasted with that of 
the highest Apes alone.

PLATE XI. 
Fig. 1. Scapula of an adult male Boschisman, from the skeleton No. 5357 in the col- 
lection of the Royal College of Surgeons. 
This shows the remarkably convex superior (in all but Man anterior) 
margin. 
Fig. 2. Scapula of Cynocephalus (No. 4731 in the same collection), showing the enor- 
mous convexity of the anterior margin and the prominence of the process for 
the trapezoid ligament ; also the obtuse termination of the acromion. 
Fig. 3. Front view of the glenoid surface of the same, showing its elongation, the small 
height attained by the acromion, the extreme shortness of the coracoid pro- 
cess (a), and the great relative length of that for the trapezoid ligament (b). 
Fig. 4. Scapula of Mycetes, from the skeleton No. 4718 B. in the same collection. 
This shows the peculiar process (x) in front of the suprascapular foramen ; 
also the very large size of the supraspinous fossa, and the flattening of the 
margin of the spine.
