 against the head, white over the whole crown (with a few black 

 hairs), but darker tipped on the back of the head ; sides of the 

 face from the orbits to the ears quite black; occipital hairs 

 directed backward, not forward as in S. thomasi. Chin, sides 

 of neck, throat, and chest greyish, not white as in the allied 

 species. Under side of the body and inner side of the upper 

 arms, and the legs to the ankles white, becoming greyer distally ; 

 hands and feet shining black ; fore-arms to the wrists, and legs 

 to the ankles, grizzled grey, as also the tail, above and below.

 frontals, shutting out the former bones from the side of the 

 nasals. In the allied species the skin of the face is nearly, 

 or quite, black all over, and the chin, sides of the neck, the 

 throat, and the chest are pure white.
