LASIOPYGA 377 



edge, remaining portion speckled bufT and tawny ochraceous. with a 

 bright buff band crossing at base of tail ; inner side of thighs buff ; tail at 

 root speckled, hair brown and black, remainder jet black. Ex specimen 

 from the White Nile, (Petherick) ; Schlegel's type of L. neglecta, 

 British Museum. 



In coloration this type is as different from what is ordinarily con- 

 sidered to be L. NEGLECTA as can be conceived. It has none of the 

 gray color about it, and the general tint is more brown than any shade 

 of gray. Dr. Gray described it as gray brown, but the gray on basal 

 part of the hairs does not show through, and affects in no appreciable 

 degree the general hue of the pelage. There are examples of so-called 

 L. neglecta in the British Museum from the Omo River, the Charada 

 forest and Kaffa, north of Lake Rudolf in the east, to the French 

 Congo, and the Ja River in Cameroon, but none of them agree in 

 color with the type, although they do with each other. Unless a gray 

 Lasiqpyga is obtained on the White Nile, to prove that the type of L. 

 NEGLECTA represents a stage of pelage unknown in so-called neglecta 

 from other parts of Africa, it would seem that the only proper way 

 will be, in the future, to restrict the name neglecta to this White Nile 

 form, and the name for the gray animal would be L. brazz.^, conferred 

 by A. Milne-Edwards upon the gray monkey from the Upper Congo, 

 for it is impossible to recognize that form from a correct description of 

 the type of L. neglecta. Mr. Pocock in his paper on Cercopithecus, 

 (Lasiqpyga), speaks of this type of Schlegel's among other examples 

 from the Omo River and Kaffa, as the "typical form," but nowhere 

 refers to it as The type of the species, and by uniting it to the examples 

 from other localities, brings together individuals as different in coloring 

 as can be imagined. 



I have not been able to find any skull belonging to the type. There 

 is a young specimen of Lasiopyga in the British Museum, presumably 

 from the Welle River, procured by the Alexander and Gosling Expedi- 

 tion, which differs in color from all others and may be described as 

 follows : 



Over each eye is a short black line composed of stiff hairs, and 

 between these and over the nose is a cream buff line of short hairs; 

 across the forehead is a band, broadest in the middle, ochraceous 

 rufous ; rest of head above speckled black and cream buff, base of hairs 

 purplish gray; sides of head and face speckled gray and yellow, the 

 latter predominating; upper parts of body gray, speckled with brown 

 and pale yellow ; rump purplish gray ; outer side of thighs purplish gray
