 1 (5 juv. 12. 8. Lumbwa. — 1 Q ad. 19. 9. Kiambu. 



In the interior of the dense forests in the regions of Nai- 

 robi this bird was quite common. The female's feathering agrees 

 perfectly with Reich enow's description (op. cit.), but that 

 of the male is different, inasmuch as the specimen is changing 

 to the adult dress. Thus, the upper surface is blackish with a 

 blue metallic gloss without any transverse bands, but on the 

 lower surface there are found here and there among the black 

 feathers, the whitish feathers, with black transverse bands, of the 

 juvenile dress. 



The wing-coverts and secondaries are edged with yellow.

This Cuckoo— Shrike was fairly common on the outskirts 

 of the forests on the eastern slopes of Mount Elgon. It always 

 appeared in pairs and usually frequented the branches of the 

 acacias. 



The male specimens are very similar to quiscalina, although 

 they have not such a pronounced purple gloss as that race, but 

 the female differs from the female of that race in the characters 

 given by Jackson (op. cit.). — v. Someren (Ibis 1916, 

 p. 385 — 386) has given a splendid table of martini and closely 

 related forms and I agree entirely with him. Neumann's 

 careful analysis of the Campephaga family (Journ. f. Orn., 1916, 

 pp. 146—154), which was published a few months before v. S o - 

 m e r e n ' s . shows that both investigators have reached nearly 

 the same results as to the systematisation of martini, although 

 the latter writer also touches upon the plumage of the males. 

 In my specimen, however, the throat is not white, but grey.
