Ilab. Madagascar. B. M. 



Both Schreber's and Eraser's figures leave out tho peculiar stripes

Lemur rufus (Geoff.), Maid roux (Audeb. Makis, t. 2), seems

 only a variety. 



Lemur rufwenter (I. Geoff. Cat. Marara. p. 71) and Lemur jlaviv enter 

 (I. Geoff. Cat. Mamm. p. 72) are probably allied species.
