Rhodesia. 
Type. Female skin and skull imperf., B.M. no. 21.11.15.1, 
presented by G. S. Ludham, Esq. 
A skin in the collection from N.W. Rhodesia, presented 
by Mr. R. L. Scott, is almost identical with this series, but 
is a little darker on the fore parts. The forehead of this 
specimen is dark umber-brown with rufous  superciliary 
streaks. 
Cephalophus monticola ruddi, subsp. n. 
Resembles nyase, except that the head is greyer, with less 
distinctly rufous superciliary streaks ; the central dorsal 
surface is a deeper brown, with a more abrupt change to 
rufous on the flanks; the fetlocks on all four legs are 
greyish brown, being rufous in nyase. 
Description.—Skin. Nose, forehead, neck, and central 
dorsal surface to neck liver-brown, becoming darker at root

Hab. Sibedeni, N.W. Eshowe, Zululand. 
Type. Adult female skin and skull, B.M. no. 4.5.1.81, 
presented by C. D. Rudd and collected by C. H. B. Grant. 
This local race in colour resembles most nearly nyase, 
but is smaller. It differs from monticola in its darker and 
redder coloration. 
In the Rudd Exploration Collection are three skins from 
the Gorongoza Mountains in Portuguese Kast Africa, which 
appear identical with the typical monticola of the Cape in 
being without rufous on the flanks, greyer on the under- 
parts, and a duller rufous on the legs. 
Thus a form indistinguishable from typical monticola is 
found intervening between the Zululand and the Nyasaland 
forms. 
Cephalophus monticola fuscicolor, subsp. n. 
A dark form from the Melsetter district, S. Rhodesia, in 
which the rufous tint characteristic of the monticola group 
is almost completely suppressed. 
Description.—Skin. Upper parts uniform slaty brown, 
slightly darker on head, rump, and tail ; fore legs the same
