ME. ST. GEOEGE MIYAET ON THE SKELETON OF THE PEIMATES. 
It is decidedly longer than its homotype of the manns in Man, Troglodytes, the long- 
tailed Simiidse, and Indris, being in Colobus nearly three times as long. The two seg- 
ments are about equal in Cynocephalus, in the Cebidse (except, of course, Ateles), in 
Lemur, Galago, Loris, Arctocebus, and Tarsius. On the other hand, it is decidedly 
shorter in Simia, Hylobates, Hapale, Perodicticus, and Cheiromys. 
It is always shorter than the first metatarsal, but at the same time is more than half 
its length, except sometimes in Simia and Hylobates and the lower Simiidse, especially 
Semnopithecus and Cynocephalus. 
The second phalanx is more than half the length of the first, except in the Semno- 
pithecinse, sometimes in Macacus, in Nyctipithecus, Hapale, and Tarsius, in which last 
it is very short, as compared with the proximal phalanx. 
It is always flattened from above downwards at its distal part. 
The 'phalanges of the other digits are, except in Man, very similar to those of the 
manus, but, as in him, they are narrower transversely than their respective homotypes. 
This difference is less marked below the Simiidse, yet always exists except in Tarsius, 
and sometimes, perhaps, in the Nycticebinse. 
They are convex above and flattened or concave below ; but in Man the shafts aTe so 
short that the inferior flattening is inconspicuous. 
The distal ends of the several joints are formed nearly as in Man, except as regards 
the distal ends of the ultimate phalanges of some. 
These ultimate phalanges are always flattened distally, more or less, as in Man, 
except in Hapale, where they are laterally compressed, curved, and pointed, like those 
of the manus ; in the index of the Lemuridse, which is elongated and pointed at its 
end ; in Cheiromys, where they are “ subcompressed and acutely pointed”*; as also in 
Tarsius. 
The proximal phalanx of either the second or the third digit is the longest phalanx 
of all the four outer digits of the same pes in the Anthropoidea. In the Lemuroidea 
that of the fourth digit is the longest. 
The length of the phalanges may be perhaps best estimated by selecting those of the 
third digit. 
The proximal phlanx of this digit is much less than half the length of the third me- 
tatarsal in Man ; it is about half the length of the latter in the Simiidse below the Si- 
miinse, and in Hapale. 
It is a little longer than the third metatarsal in Galago and some of the Nycticebinse. 
No proximal phalanx of any of the four outer digits exceeds its supporting metatarsal 
in the Anthropoidea ; but in Galago, the Nycticebinse, Tarsius, and Cheiromys, that of 
the fourth digit exceeds in length the fourth metatarsal ; and in Galago, Loris, and Pe- 
rodicticus f the same may be said of the third digit. 
The proximal phalanx of the third digit greatly falls short of the length of its homo-
