We have now a series of three adult males, one immature 

 male, and one female. These agree in every detail with tlie 

 type, which, as stated by Dr. Hartert, was compared with 

 the types of C. polioptera and C. nigriceps by Prof. Neumann. 

 The series bears out the original description in every point 

 except that of the superciliary stripe. There are even in the 

 type a few black-tipped feathers. The wing of C. polioptera 

 is given as 74 mm. In these specimens it varies from 

 78 mm. (?) to 84 mm. {S)- 



The young bird has the feathers of the crown dark 

 ochraceous, with each feather edged with black. A few 

 white feathers are present, just above the eye. The back, 

 under surface, and tail are lighter in colour than in adults. 

 The uppermost secondaries are edged with ochraceous, while 

 the secondary and lesser coverts are edged and tipped with 

 the same colour. 



They nest in June and October, and the eggs are olive- 

 green. They are birds of the forest-undergrowth, and are 

 accordingly easily overlooked. 



Localities. Mabira, Kyetema, Kasala, Wabigenge River, 

 and Sezibwa River, in Uganda.

This is the pale form of C. cyanocampter, the type of which 

 came from the Aruwimi River. Unfortunately, I have no 

 specimens from the type-locality to compare with my birds. 

 A young bird in first plumage was shot in September. It is 

 mottled and lacks a superciliary stripe, and has no blue on 

 the shoulder. 



This is a shy and retiring bird which keeps to the thickets 

 of the forest. 



Locality. Mabira Forest, Uganda.
