1863.] DR. J. E. GRAY ON THE SPECIES OF LEMUROIDS. 147 



ears large ; tail elongate, rather longer than head and body, subela- 

 vate, rather browner than the back. 



Length of hind foot 2" 5'". 



Var. smaller ; orbits darker. 



Length of hind foot 2" 3'". Skull, length 1" 6"', breadth 1" 0'". 



Hab. South Africa. 



Brown's figure seems to represent this species ; but the hind foot 

 is too short — having about the same proportion, compared with the 

 shank-bone as Lepilemur ; therefore I have only referred it to this 

 species with doubt. 



The fine male specimen which served as the type of Sir Andrew 

 Smitii's figure has the orbits of the same colour as the rest of the 

 face ; in two other rather smaller specimens in the Museum the orbits 

 are darker, in one nearly black. 



There are two skulls of this species in the Museum Collection, 

 both from South Africa. They vary very slightly in the size of the 

 teeth, especially in the breadth or squareness of the grinders. The 

 upper cutting teeth are cylindrical, elongate, of the same size, and 

 placed in a nearly straight cross line ; the first upper false grinder 

 is broad and lobed, like the second one.
