 Ann. du Museum, torn xix. p. 172. 



Cheirogaleus Commersonii, Vigors and ITorsfield. Hairs of 

 the body fuscous at the base, brownish red in the centre, and 

 black at the extremity. The red pre\ails along the ridge of 

 the back and on the base of the tail. The ears are clotlied 

 with hairs at the base, inside and outside, their margins are 

 naked; the extremity of the toes and nails arc black. The 

 length from the forehead to the root of the tail is thirt6en 

 inches and a half; of the tail seventeen inches : the height from 

 the tip of the shoulder to the wrist seven ; the length of the 

 fore hand, from the wrist to the end of the middle nail, is two 

 inches and tlircc quarters ; of the hind hand, similarly measured, 

 three inches and a half. The hairs on the forehead of this 

 animal diverge in the centre, leavinjr a white mark over each 

 eye, while their extremities being black form a dark line on 

 each side, which runs backwards gradually widening to the 

 hind head. 



Obs. This animal, thougli it can no longer be viewed as a species of 

 the Genus Cheirogaleus, is probably of African origin, and on that ac- 

 count I have eiitesed it here. Messrs. Vigors and Horsfield, who describe 

 it, observe:* — " The incisor teeth are four in number in each jaw, ex- 

 tremely regular ; those of the upper jaw are unusually strong, and nearly 

 cylindrical. The nails do not agree with those of M. I'onimerson's figures; 

 they more resemble those of the monkeys." It will probably be found to 

 form the type of a new genus. 



Order CHEIROPTERA. 



Fingers of the anterior extremities connected by a membrane 

 which spreads from the anterior to the posterior extremities, 

 and in many of the species also connects the -latter to each 

 other, forming altogether an apparatus more or less effective 

 for flight. Incisive teeth various in number ; canines more or 

 less strong; cheekteeth, in general, having their crowns fur- 

 nished with several acute points ; hut in the first genus a single 

 regular furrow or indentation passes along tlie whole series ; 

 both sides of each tooth approacliin^: the figure of the transverse 

 section of a cone, a little convex, notched on the upper edge 

 from right to left. Mamniie, in general two, pectoral.
