 eyes covered with hairs speckled white and black ; rest of head, neck 

 behind, and on sides, space between shoulders, shoulders, arms, hands, 

 legs, feet and tail except at base, jet black ; body above and below shoul- 

 ders, and flanks iron gray, the hairs being gray and banded on apical 

 half with black and white ; chin and throat white ; rest of under parts

The unique type of this form in the British Museum is stated to 

 have come from West Africa, but no particulars are given. It seems in 

 its jet black legs and under parts to be more nearly allied to L. BOtJ- 

 TOURLiNi than to L. stuhlmanni and differs from it in having the 

 cheeks and sides of the neck jet black, and in the white brow band.
