MR. G. R. WATERHOUSE ON THE GENUS GALEOPITHECUS. 339 
their position, compressed, narrow at the base, and suddenly expanded immediately 
above the base: each incisor is deeply pectinated, or subdivided by incisions into slen- 
der lamine. These lamine vary in number in the teeth of different individuals of the 
same species. In the present species of Galeopithecus, I find, in the middle pair of in- 
cisors, either seven or eight, and in the outer pair either eight, nine, or ten lamine: 
each of these slender processes is dilated, and slightly recurved the apex, and on the 
outer and apical portion there is a broad longitudinal groove. The lateral amine are 
broader than those intervening’. The incisors and false molares of the upper jaw are 
detached: between the first and second canine there is an intervening space of nearly 
half a line, and the latter is distant about one line from the first false molar on either 
side: between this and the second false molar the space is about one quarter of a line, 
and behind the second false molar there is a vacant space of about one third of a line. 
The canines and false molares of the lower jaw are also detached.

Colour very variable ; sometimes deep blackish-brown above, and brown beneath, 
with a few scattered small white spots on the upper parts ; or the upper surface is grey, 
variegated with black and white, and the under surface brownish white. 
This species is so variable in its colouring, that in this respect I can find no charac- 
ters in common. I may observe, however, that the two males sent by Mr. Cuming 
agree in being of a dark blackish brown colour, and almost uniform ; one of them has 
a large white spot on the upper surface of the muzzle, and a similar patch of white is 
observable in the two females, but varying in size ; in the other male, however, there is 
no trace of this spot. The two females are of a much paler colour than the males ; one 
is of an ashy-grey colour above, variegated with black and white, and of a very pale 
brown or brownish white colour beneath. The other female is of a yellowish grey tint 
above, clouded with deep brownish grey on the fore part of the arms and on the feet ; 
the latter are spotted with white. A large patch of grey is observable on the upper 
side of the flank membrane, near the sides of the body, in which there are two or three 
small white spots; and towards the hinder feet there is a large dirty yellowish white 
patch. ‘The under parts are brownish white, with a faint yellow tint. 
' The six foremost teeth in the lower jaw of the Lemur (four of which are incisors, and the remaining two 
I agree with Geoffroy in considering as canines,) together bear a remarkable resemblance to a single incisor 
of Galeopithecus. The two canines may be compared to the outer Jamine of one of these incisors. Like one of 
these /amine, the Lemur’s canine is dilated immediately above the base, and has a longitudinal ridge on the up- 
per side, whilst the incisors, like the intermediate /amine, are grooved on the outer side, near the aper. In 
their almost horizontal direction there is also a resemblance. In the number of teeth the Galeopitheci agree 
with the Lemurs, excepting that in the former the upper canines are wanting. In both these groups of animals 
the incisors of the lower jaw are opposed to a toothless portion of the intermaxillaries.
