Mr. W. L. Sclater on Birds collected 
West-African type-form, C. sulphur eopectus, but I confess 
that I cannot distinguish it from the Orange-breasted Bush- 
Shrike of East Africa called C. s. chrysogaster by Reichenow. 
[I have only found this species in the patches of dense 
thorn-bush scattered along the Umfolosi River in S.E. 
Zululand, and iu the thickets bordering many parts of the 
banks of the Klein Letaba in the N.E. Transvaal. It is a 
skulking and raiher wary bird and is seldom seen, but its 
whistling call can often be heard. 
The soft parts are :—Irides dark hazel ; bill black ; legs 
and toes dark slate-coloured. In the $ the base of the lower 
mandible is palest.] 
206. Malaconotus olivaceus starki. 
P. Coguno, July, Aug. (3) ; Tete, Sept. (1). 
[I have noted this Shrike from the Eastern and North- 
Eastern Transvaal and the Inhambane, Beira, and Tete 
districts of Portuguese East Africa. It usually frequents 
dense bush and thickets and is more often heard than seen, 
its peculiar note being unmistakable. This call is a soft sort 
of cluck followed by a long loud whistle, the bird as it emits 
the sound throwing back the head and opening the beak. It 
is probably always in pairs although only single individuals 
are usually observed. 
The soft parts are:—Bill black; legs and toes slate- 
coloured. 
A male from Tete has the bill pale brown with darker 
markings, and is probably immature.] 
207. Nicator gularis. 
P. Coguno, June (1); Tete, Sept. (1). 
[The two birds secured are the only specimens I have seen 
of this species, and both were shot in the thickets. It appears 
to be a solitary and silent bird, and keeps to the lower branches 
of the trees and bushes in the densest scrub and thickets. 
It is not, I think, uncommon, but owing to its skulking and 
silent habits is easily overlooked. 
The soft parts are:—Irides hazel; bill greyish brown; 
legs and toes slate-coloured. In the female the bill is much 
paler.]
