21. The great length of the same (more than double) compared with that of the 
humerus. 
22. The great length of the same compared with that of the radius. 
23. The narrowness, of the proximal end of the tibia compared with the length of the 
bone. 
24. The high position of the tubercle on the shaft of the tibia. 
25. The anchylosis inferiorly of the tibia and fibula. 
26. The great length of the whole pes compared with that of the spine. 
27. The great length of the tarsus compared with the sqme. 
28. The small breadth of the tarsus compared with its length. 
29. The great length of the os calcis compared with that of the spine. 
30. The very small length of the cuboid compared with that of the os calcis. 
31. The great length of the hallux compared with that of the spine. 
32. The great length of its metatarsal similarly compared. 
33. The longest digit equalling very nearly half the length of the spine. 
34. The shortness of the second metatarsal when compared with the length of the 
whole pes. 
35. The shortness of the third digit (without its metatarsal) compared with the 
same. 
Cheiromys. 
This aberrant form, the close affinity of which to the other Lemuroids has been 
lately placed beyond the possibility of dispute differs from all the rest of the order 
except Tarsius, in the length of the manus compared with that of the spine ; and I 
find the same to be the case with respect to the pollex, though here it is sometimes 
very closely approached, if not equalled, by Hylobates. 
The longest digit, with its metacarpal, is also longer, when compared with the spine, 
than in any except Tarsius. 
The index is longer, compared with the spine, than in any other Primates except 
Tarsius, Simia, and Hylobates. 
The first phalanx of the third digit is longer, in proportion to the length of the 
manus, than in any other Primate except Tarsius. 
The length of the tibia, compared with that of the spine, is greater than in any others 
of the order except Man, Hylobates, Ateles, and Tarsius ; its length, compared with 
that of the humerus, is only exceeded by Hapale, Galago, Indris, and Tarsius; and 
compared with that of the radius, by Man, Callithrix, Hapale, and Tarsius. 
The proportion of the tibia to the femur is greater than in any other Primate 
except Hapale. 
The length of the pes, compared with the rest of the pelvic limb, is greater than in 
any other Primate except Simia.
