breadth, 11; breadth across post-orbital processes, tip to tip, 17; 

 breadth of braincase, 19; teeth well worn. 



F. mayumbicus is a well-marked species; readily distinguished from 

 lemniscatus by its colour, and by the narrow skull with its promi- 

 nently rounded braincase. 



Jentink (Notes Leyd. Mus. IV, 1882, p. 36). makes F. sharpei, 

 Gray, and F. isabella, Gray, synonyms of lemniscatus. This is cer- 

 tainly correct so far as sharpei is concerned, but isabella is quite a 

 différent species, as an examination of the type in the British Muséum 

 shows. The B. M. has a good séries of both species. They are found 

 dwelling side by side on the Ja River.

Similar in appearance to P. s. nigeriae, from which it differs in the 

 following points : — (1) speckling of the body a deeper, golden yel- 

 low; (2) head pure black speckled with white, sharply defined from 

 body colour; (3) hairs of throat and chest not wholly white, having 

 black bases; (4) upper surface of fore feet rufous; (5) no white line 

 at the side of the belly; (6) tail red and black for proximinal two- 

 thirds, white and black for distal third. 



Type (juv.) collected by Dr. H. Schouteden, in the Musée du
