 This genus can bo divided into two sections : — 



I . Nose tapering, narrow in front ; shall, nose tapering, narrow in front ; 



palate dilated behind ; series of grinders converging in front. Lower 

 jaw broad and strong in front, toiih a long symphysis. IIai'ALKMUR. 



Hapalemur griseus. 



Hapalemur griseus, Sclater, P. Z. S. 1803, p. 101; Mivart, P. Z. S. 

 1804, p. 013, fig. skull (copied, Cat. Monkeys Sfc. B.M. p. 77). 



II. Ab.se 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-gvoy, with a rufous tingo ; tho hairs black, with a 

 subapical rufous band, and tho lower part lead-coloured ; throat 

 whitish ; patch on rump at base of tail yellowish.

 t. 7. fig. 4 (skull without upper cutting-teeth). 



llab. 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 tho hinder part of the lower jaws 

 of the two species. The front of the jaw in II. griseus is very much 

 more slender and weak than in II. simus. 



The colour of tho fur is exactly similar to that of //. 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 Coquerelii and L. furrifer ; but the 

 latter differs in tho very large size and the projecting central upper 

 cutting-teeth.
