This species is of a smaller size than G. Temminckii ; the limbs, however, are con- 
siderably stronger, the bones being proportionately thicker’; the hands* and feet are 
larger, and the ears are also larger. Upon comparing the skull of G, Philippinensis with 
that of G. Temminckii, the most striking differences consist in its smaller size, its nar- 
rower and more ovate form, the shorter and more obtusely terminated muzzle. The 
temporal ridges in the adult animal meet near the occiput, or are separated but by a very 
narrow space. The rami of the lower jaw are shorter, and proportionately deeper and 
thicker. They diverge less suddenly from the symphysis menti.

In the dentition there are also many marked differences. The molares of the present 
animal are considerably larger than those of G. Temminckw, the longitudinal extent of 
the grinding surface of the five posterior molares of the upper jaw being 103 lines, the 
'! The diameter of the thigh bone of G. Philippinensis is 3 lines, whereas that of G. Temminckii (a larger ani- 
saat) is only 2} lines. 
2 | may observe, that sien the thumb is furnished with a compressed claw, like that of the fingers, and is 
enveloped in membrane, we can trace an approach to the Lemurs in the structure of this member. The thumb 
is in fact semi-opposable, and separated from the fingers by a considerable interval. The metacarpal bone is, 
as in the Lemurs, short, and the extremity of the thumb is nearly on a line with the ends of the metacarpal 
bones of the fingers.
