290 Mr. W. L. Sclater on Birds collected 



We»t-A£iicau type-form, C. sulplnireopeclus, but I confess 

 that I cannot distinguish it from the Orange-ljreasted Bush- 

 Shrike of East Africa called C. s. chrysogaster by Reichenow. 



[I liave only found this species in the patches of dense 

 thorn-bush scattered along the Umfolosi lliver in S.E. 

 Zululand, and in the thickets bordering many parts of the 

 banks of the Klein Letaba in the N.E. Transvaal. It is a 

 skulking and rather 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. MaLACOxMOTUS olivaceus starki. 



P. Coguno, July, Aug. (3) ; Tete, Sept. (1). 



[1 have noted this Shrike from the Eastern and Nortli- 

 Eastern Transvaal and the Iiihauibane, Beira, and Tete 

 districts of Portuguese East Africa. It usually frequents 

 dense bush and thickets and is more often heard than seen, 

 its ijcculiar 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 althougli 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. NlCATOR 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. lu the female the bill is much 

 paler.]
