beyond the red at base), is speckled black and buff; forehead covered 

 with long hairs banded with black and white, or black and buff ; top of 

 head speckled yellow and black, yellow predominating. Ex type 

 British Museum. 



Measurements. Head and body, 610 ; tail imperfect ; foot, 125,

Compared with L. stairsi, the type of L. s. mossambicus is a very 

 much older animal, and a male. It is an open question whether L. 

 STAIRSI male, equally adult, would not change the coloring as regards 

 the speckling on back, and color of the speckling of thighs, which 

 comprise the principal differences. 



The type of L. stairsi is a baby, and some of its hair, like that on 

 the tail, is little better than down. It will be necessary to have old 

 adults of both forms to compare, before it can be definitely determined 

 that they are distinct.

 and dorsal region. Its locality is farther from that form than is that
