9. The dorsal grooves limiting the articular heads proximally are generally less marked. 
The manus in Apes and Lemuroids agrees with the hand of Man and differs from his 
foot, in that — 
1. The length of the manus is almost always less than that of the pes in the same 
individual. 
2. The length of the manus, compared with that of the spine, is almost always less than 
that borne by the pes to the spine in the same individual. 
3. The length of the carpus, as compared with that of the spine, manus, and digits, is 
smaller than that of the tarsus, as compared with the spine, pes, and digits, in the same 
individual. 
4. The form, arrangement, and connexions of the bones are similar. 
5. At least two bones of the manus articulate with the long bones of the limb. 
6. There is a convex cylinder supporting the innermost digit, and its long axis forms 
an obtuse angle with a line joining the proximal ends of the metacarpals. 
7. The cuboides has an unciform process and no transverse groove. 
8. The line joining the proximal ends of the metacarpals never inclines outwards and 
backwards. 
9. The metacarpals expand distallv. 
10. The antero-posteriorly directed planes, traversing the metacarpals from the dorsum 
to the palm, converge palmad. 
11. The metacarpals are broader than the metatarsals of the same individual. 
12. The pollex with its metacarpal is almost always shorter than the hallux with 
its metatarsal, in the same individual. 
13. The pollex generally extends less far forwards with relation to the index of the 
manus, than does the hallux with relation to the index of the pes. 
14. Except in Perodicticus, the proportion of the longest digit to the longest meta- 
carpal always exceeds that of the longest digit of the pes to the longest metatarsal. 
15. The phalanges of the manus are broader than their homotypes of the pes in The 
same individual. 
16. The angle formed by the transverse diameter of the head of the pollex with a line 
connecting the heads of the other metacarpals is similar to the homologous angle in Homo. 
17. Neither the first nor the second digit is the longest one. 
18. The lengths of the phalanges, and hence of the digits, are similar. 
The manus of Apes and Lemuroids differs from the hand of Man and resembles his 
foot, in that — 
1. The proportion, as to length, borne by the manus to the rest of the pectoral limb 
almost always falls short of that borne by the pes to the rest of the pelvic one, reversing 
the conditions in Man. 
2. The proportion borne by the manus to the radius is generally less than that borne 
by the pes to the tibia. 
3. There is a strong dorsal flexion of the metacarpo-phalangeal joints.
