472 XAXTHOl'HILUS OLIVACEICEPS 



specimens on Uliambiri Island off the south-west coast of 

 Victoria Nyanza, and it was apparently abundant at both of 

 these extreme limits of its known range, for he records it as 

 common at the latter place, and at "Wadelai he collected the 

 five typical adult specimens all labelled male, and an evidently 

 immature bird, which I have described, is labelled female. 



The full plumage is probably attained for their first 

 breeding season, and is subject to no seasonal change, judging 

 from Dr. Ansorge's specimens obtained in Torn in April, and 

 by Jackson's collection, which contains a male and female from 

 Kama Island, August, and two males and four females shot at 

 Ntebbe, March and August. The females and immature birds 

 may easily be mistaken for hens of Hyphantornis spekei, but 

 the bill is more slender.

 by the description and figure of the type.
