Page 76. HAPALEMUR. 
This genus can be divided into two sections :— 
I. Nose tapering, narrow in front; skull, nose tapering, narrow in Front ; 
palate dilated behind ; series of grinders converging in front. “Lower 
jaw broad and strong in front, with a long symphysis, Hapatemur. 
Hapalemur griseus. 
Hapalemur griseus, Sclater, P. Z. S. 1868, p. 161; Mivart, P. Z. S. 
1864, p. 613, fig. skull (copied, Cat. Monkeys Se. B.M. p. 77). 
II. Nose broad and truncated ; skull, nose very broad, square, truncated in 
front; palate scarcely wider behind; series of grinders wide apart 
and nearly parallel. Lower jaw weak, and narrow in front, with a 
short symphysis. PROLEMUR. 
Hapalemur simus. B.M. 
Back iron-grey, with a rufous tinge; the hairs black, with a 
subapical rufous band, and the lower part lead-coloured; throat 
whitish ; patch on rump at base of tail yellowish. 
Hapalemur griseus, Schlegel § Pollen, Fauna Madagase. p. 6, t. 8 & 
t. 7. fig. 4 (skull without upper cutting-teeth). 
Hab. Madagascar. 
This may be Hapalemur olivacea ; but that species is very imper- 
fectly described, and it is said to have a different form of the hinder 
part of the lower jaw; but what the difference is is not mentioned, 
and I do not see any difference in the hinder part of the lower jaws 
of the two species. ‘The front of the jaw in H. griseus is very much 
more slender and weak than in H. simus. 
The colour of the fur is exactly similar to that of H. griseus; only 
there is a pale spot on the rump at the base of the tail, which may 
be accidental, or caused by the manner in which it was confined in 
its cage. 
Page 78. 2. Cheirogaleus typicus. 
Skull :—Brain-case ovate, elongate, rather depressed ; nose rather 
elongate, conical ; orbits large; palate rather broad in front, much 
broader behind; upper cutting-teeth 2.2, in an arched series, 
compressed, erect; inner thicker, and quite as long as the outer 
ones, converging towards the central line. Tail of animal cylindrical, 
covered with soft woolly hair. 
Skull in shape like Lepilemur Coquerelit and L. furcifer ; but the 
latter differs in the very large-size and the projecting central upper 
cutting-teeth.
