No. 17, p. 7. October 21. (Summit of Mau Escarpment, between 
Londiani and Sirgoit, British East Africa; type in U. 8. National Mu- 
seum. ) 
Specimen.—One, the type, from— 
British East ArrioaA: Wagon road, Londiani to Sirgoit, 1 
(White). 
The type-specimen of this form was collected by Mr. John Jay 
White, November 1, 1910. It resembles very closely specimens of 
Lasiopyga leucampyx neumanni, but has more buff, less gray, in the 
coloration of the upper parts; larger skull, with well-developed sagittal 
crest; and larger teeth. This form is the easternmost representa- 
tive of the leucampyz group. 
Doctor Lénnberg has recently described a subspecies from Mount 
‘Elgon, as Cercopithecus leucampyzx elgonis,' that would seem to be 
more closely related to Lasiopyga leucampyxr maue than to L. l. 
neumannt.

No. 17, p. 10. October 21. (Ndi, Taita District, British East Africa. 
type in U. 8. National Museum.) 
Specimens.—Ten, from the following localities: 
British East Arrica: Mtoto Andei, 2 (Heller); Ndi, 6 (Heller) ; 
Voi, 2 (Heller). 
This pale form of the pygerythra group has a very sharply bicolored 
tail, with the median stripe above blackish and well defined, and the 
underside clear yellowish buff. In its typical form it is apparently 
confined to the Taita Hills region, as the specimens from near the 
coast at Changamwe, which were included with it by the original 
describer, are clearly of another subspecies. The two specimens from 
Mtoto Andei are both females and one of them is immature. They
