well as of the old. Whether this character is sufficient to name a 

 special local form of the C. superciliosus living at Victoria Nyanza 

 I am not able to decide at present. 



Grant has (Bull. Brit. Orn. Club, vol. XXXV, 1914, p. 54) 

 described a new form of C. superciliosus, named C. s. loandae, 

 and judging from the description the Rendu specimen should, I 

 suppose, belong to this race. Not having seen any specimens 

 belonging to this formv however I dare not exp ressany positive 

 opinion on the matter. 



According to Grant the distribution of this form is from 

 Angola to the north of Congo River, eastwards to eastern Bel- 

 gian Congo and north-eastern Rhodesia. But the same writer 

 also points out that intermediate specimens of this race and C. 

 s. superciliosus are found in German East Africa, British East 

 Africa and in Uganda- and therefore the Kendu birds may be 

 such intermediates. 



The newly described C. s. intermedius by v. Someren 

 (Bull. Brit. Orn. Club, vol. XLI, 1921, p. 125) which „differs 

 from the typical South-Arabian bird in being darker above and 

 smaller. Wings 140—155 mm" can scarcely be considered as a 

 good form, but is, I dare say, only a subtile form between 

 superciliosus and loandae (vide Grant). Among the Kikuyu spe- 

 cimens some are fairly light above and others darker and the 

 variations in the measurements of the length of the wing can 

 be seen in the table below. 



V. Someren does not give the distribution of inter- 

 medius (terra typica: Mombasa) but if the author considers this 

 new form only as a new coastal bird, it is possible that the 

 description agrees with respect to the wing- measurement. My 

 specimen from Mombasa belongs to the light forms, but in spite 

 of the fact that the wing-measurement falls within the 140 — 155 

 mm given by v. Someren I cannot support his new form, 

 which is probably nothing but a casual individual variation. 

 In C. €. superciliosus the wing is 140 — 150 mm. 



The two most interesting individuals were shot in the en- 

 virons of Nairobi. They are a beautiful brownish -red all over 

 the under-surface of the body; the head and interscapular region 

 being of the same colour. But this beautiful colour disappears 

 at once if a damp piece of cotton -wool is drawn across the 

 leathers, and is thus only a superficial wash caused by the 

 discoloration of the ground. 



In the young bird the rectrices are more glossy green 

 than in old birds and tapering at the tips (in the old they are 

 rounded) and are furnished with 3—4 narrow, white transverse 

 bands. The young bird from Kendu (Victoria Nyanza) is also 

 unlike the one from the Nairobi regions in that the feathers of 

 the back and sides of the neck, in addition to the rusty-brown 

 streak nearest the shaft, have a triangular yellowish-brown spot
