type in Man ; it falls less short in Troglodytes, Tarsius, and Cheiromys, and less still in 
Simia and Hylobates. 
Often the two are nearly equal, and sometimes that of the pes is a little in excess. 
In Loris and Arctocebus it is considerably so. 
The second phalanx is always more than half the length of the proximal phalanx, ex- 
cept in Tarsius, where it is a little less. 
As compared with its homotype, it is less than half only in Man and Tarsius, 
but it is very little more than half in the Chimpanzee, and sometimes in Hylo- 
bates. It is still considerably shorter than its homotype in the Gorilla, Simia, Gd- 
lago, and Cheiromys; in the rest there is but little difference, and the phalanx of the 
pes is sometimes a little the longer. In Indris, Loris, and Perodicticus it is de- 
cidedly so. 
The third phalanx , as compared with the second one, is longest in Man, where it some- 
times equals, and indeed even exceeds, the latter in length. It is often less than half 
the length of the second phalanx in other forms. 
It is much shorter than its homotype, in Man and in all the Simiinse. In the other 
forms there is no great difference, that of the pes being sometimes a little the shorter, 
sometimes, as in the Nycticebinse, a little the longer. 
The phalanges of the four outer digits shorten successively, except in Tarsius and 
sometimes in Galago, where the second phalanx of the fourth digit is as long as the 
proximal one of the index, and in the Nycticebinse, where the latter is actually shorter. 
Digits without their Metatarsals. 
The hallux thus measured is absolutely longest in Man. 
As compared with the length of the pes, it is longest by much in Arctocebus, and then 
in the Chimpanzee and Man, Indris, and Loris, in all of which its length equals, or is 
but very little less than a quarter of that of the pes. 
Not counting Ateles, it exceeds its homotype most in Colobus. It falls slightly short 
of it in Lagothrix, Mycetes, Hapale, and Hylobates ; more considerably so in Cheiromys, 
and most so in Simia. In all the rest it equals or slightly exceeds it. 
It is the longest digit of the pes only in Man, and only sometimes in him. 
It is the shortest one in all except Man, but only in the Semnopithecinee, Lago- 
thrix, Hapale, and Cheiromys is it so small as only to equal half the length of the 
fifth digit, except in Simia, where it is sometimes less than a quarter of the length of 
that digit. 
The index is the longest of the pes only in Man, and only sometimes in him. 
It is never the shortest digit, but it is the shortest one, except the hallux, sometimes 
in Hapale, and in all the Lemuroidea. In Man alone it projects the most. In Pero- 
dicticus and Arctocebus it is unusually short, being very little longer than the hallux in 
the latter genus.
