236 Capt. G. E. Shelley on Birds from the 



As regards Laniarius and Dryoscopus, tliey are, in my 

 opinion, two very well-marked genera, which may be 

 separated as follows : — 



a. Sexes alike in plumag-e. Entire back blackish. Wing 



more rounded ; tip of second primary fells con- 

 siderably short of the tip of the secondaries 1. Laniarius. 



b. Sexes dissimilar. Back never uniform blackish ; the 



males always, and often the females, have the lower 

 back covered with white or grey fluffy feathers, 

 contrasting strongly with the mantle. Wings less 

 rounded ; tip of second primary reaches about to the 

 tip of the secondaries. Females differ from the 

 males, either totally and have a brownish plumage, 

 or else are distinguished by having the sides of the 

 forehead white , 2. Dryoscopus. 



27. Telephonus senegalus. 



Telephonus senegalus (Linn.) ; Shelley, Ibis, 1893, p. 20, 

 1894, p. 18 ; Reichen. Vog. Deutsch-Ost-A£r. p. 158. 

 Zomba. Two specimens. 



28. Oriolus larvatus. 



Orio/us larvatus, Licht. ; Shelley, Ibis, 1893, p. 22; 1894, 

 pp. 19, 470. 



Oriolus rolleti, Reichen. Vog. Deutsch-Ost-Afr. p. 168. 



Zomba. One specimen. 



I cannot agree that O. rolleti is even subspecifically 

 distinct from O. larvatus. From an examination of a large 

 series in the British Museum, I have come to the conclusion 

 that there is no distinctive character in the plumages of the 

 specimens from South and Eastern Africa, and 0. larvatus 

 probably ranges northward in West Africa to the Cama- 

 roons. On the Gold Coast a subspecies, O. brachyrhynchus 

 (possibly a local form), may be recognized by the mantle 

 being slightly more olive and the size rather smaller: wing 

 4"3 to 4*6, culmen and tarsus 0'85 to 09. Birds from 

 S. Africa, south of the Zambesi, measure : wing 5'0 to 5*3. 

 Birds from E. Africa, north of the Zambesi: wing 4*7 to 

 5-3.
