The specimens of this species vary in the breadth of the band or

iron-grey spot on each side of the forehead. Skull elongate, length 
3” 6", breadth 2”; canines very large; interorbital space broad, 
convex; forehead flat; orbits produced on the sides,

Lemur mongoz, Schreb. Séugeth. i. t. 39 a (moderate), Lemur rufi-

Typica, t. (bad). Prosimia rufifrons, Lesson; Gray ! 
Hab. Madagascar. B. M. 
Both Schreber’s and .Fraser’s figures leave out the peculiar stripes 
on the side of the rump. 
Lemur rufus (Geoff.), Maki roux (Audeb. Makis, t. 2), seems 
to resemble this species; but we have it not: it may be 
only a variety. 
Lemur rufiventer (1. Geoff. Cat. Mamm. p. 71) and Lemur flaviventer 
(I. Geoff. Cat. Mamm. p. 72) are probably allied species.

Fur grey brown, with a broad, black, indistinct dorsal streak ; 
chin, chest, and beneath pale rufous ; head and back of neck black ; 
a large puffy spot on each side of the throat under the ear bright
