 HAPALEMUR SIMUS. 



BY 



H. SCHLEGEL. 



Dec. 1879. 



The late Director of the British Museum , Dr. J. E. Gray 

 in establishiug this species, (Catalogue of Monkeys, Lon- 

 don, 1 Dec. 1870, p. 133) assigns to it the following 

 characteristics : 



"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 et Pollen , Faune 

 Madagasc. p. 6, t. 3 et 7, fig. 4. (skull without upper 

 cutting-teeth) — Habits Madagascar. — This may be 

 Hapalemur olivacea; but that species is very imperfectly 

 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 con- 

 fined in its cage."
