1. Hapalemur griseus, I. Geoff. Cat. Meth. 75. B.M. 



Lemur griseus, Geoff. 1796. 



Maki gris, Buffon, Supp. vii. t. 24. 



Cheirogaleus griseus, Van der Hoeven, Tijdsch. 1844, xi. t. 1. f. 1 

 (skull). 



Dark iron-grey, with a yellowish tinge ; hairs black, with a sub- 

 apical reddish band ; underside rather paler. 



Hab. Madagascar. Shot in the woods. 



The upper cutting teeth are placed one before the other, and 

 crowded back so as to be on the inner side of the canine. 



2. Hapalemur olivacexjs, I. Geoff. 1851. 

 Hab. Madagascar. 



9. Cheirogaleus, Geoff. 



Myspithecus, Fr. Cuv. 1833. 



Myoxicebus et Cebugale, Lesson, 1840. 



Cheirogaleus, Wagner, 1840. 



Head very short, muzzle tapering. Ears small, hidden, bald on 

 the edge. Cutting teeth ''-^, the middle larger, in an arched series on 

 side of intermaxillaries ; the first false grinder in the upper jaw large* 

 conical, erect, like a small canine, and in the lower jaw also rather 

 large. Hind legs rather elongate, more equal than in the true 

 Lemurs. The hind feet are short and broad, about two-thirds of 

 the length of the shank. 



M. Isidore Geoffroy, in his account of the genus Hapalemur, 

 states that in Cheirogaleus " the cutting teeth are in straight cross 

 lines, and the ears are membranaceous." If this is correct, the 

 species here described are not Cheirogalei.
