It differs from all the black-nosed lemurs, except Lemur macaco 

 rujus, in its lighter color, and from the latter in its cheek and ear 

 tufts, in which it resembles Lemur macaco. Nose black; top of head 

 dark olive-buff; general color of upper parts snuff-brown to drab; 

 hands russet ; spot at root of tail and basal half of tail bay-colored ; 

 distal half of tail bushy, the hairs with blackish brown tips and with 

 a subterminal clay-colored band; a ruff of long hairs around the 

 ears and down the cheeks, varying from white to light ochraceous- 

 buff; under parts gull-gray, washed with buffy. Female without 

 cheek-tufts. Total length of male, 895 mm.; tail, 495 mm. 



This form is restricted to the rain forest of Mount D'Ambre, 

 northern Madagascar. (Archbold, 1932, p. 1.)

To judge by the 36 specimens collected by the Mission Zoologique 

 Franco-Anglo-Americaine of 1929-31 (Delacour, 1932, p. 220) , this 

 must be one of the commonest of Madagascar lemurs. 



Pelage brown; top of head, cheeks, and jaws white (. Geoffroy, 

 1796, p. 48). "Of this race there are two mutations which occur 

 together, viz., (1) a normally black-headed, whitish-cheeked type, 

 with dark ground-colour, in which the female is only slightly paler 

 than the male, and (2) the 'albifrons' type, which shows a reduction 

 of black pigment, the ground-colour being more reddish, especially 

 so in the female; the male has the whole crown, cheeks, and beard 

 white or whitish, but there are females which show a whitening on 

 the head, although the normal phase of the 'albifrons' female has a 

 lead-grey head and a grey muzzle" (Schwarz, 1931, p. 410). 



"The range of this local race apparently includes the north- 

 eastern coast of Madagascar as far as, and slightly beyond, the 

 Bay of Antongil. The northern and western limit is uncertain; 

 only the dark phase apparently occurs on the north-west coast." 

 Specimens are recorded from: Vohemar and Sahambavany, N.E. 

 coast; Mananare, Maroansetra, Androutse, and Ampazenardo, in 

 the vicinity of the Bay of Antongil. (Schwarz, 1931, pp. 410-411.) 



"The effects of hunting by natives on the animal life of Mada- 

 gascar are negligible. The main destruction of the fauna is caused
