Specimens.—Eleven, from localities as follows: 
British East Arrica: Bondoni, Kapiti Plains, 1 (Pease); Isiola 
River, 1 (T. Roosevelt); Kasorongai River, 3, including one large 
fetus in alcohol (Mearns, Loring); Machakos Road Station, 1 (K. 
Roosevelt); Ngong Hill, Nairobi, 1 (Klein); Potha, Kapiti Plains, 1 
(Loring) ; Southern Guaso Nyiro, 1 (Heller); Wambugu, 1 (Mearns) ; 
‘‘British East Africa,” 1 flat skin (Heller). 
‘The specimen from Potha is mounted and on exhibition. 
I am not at all satisfied, from a study of this material, that only a 
single form is included among the duikers here listed under Sylvicapra 
grimmia hindei. There are unaccountable variations in size and in 
minor skull characters between specimens from Mount Kenia and the 
Northern Guaso Nyiro and those from farther south, but the material 
is entirely inadequate and many of the specimens are not sufficiently 
comparable as to age for conclusive results.
