146 NIGRITA LUTEIFRONS 
upper parts are dark, with less white on the lower back and 
some white edges to the feathers of the flanks, abdomen and 
under tail-coverts. In the other specimens the under parts are 
uniform black, and the adult males and females have the upper 
parts paler and brighter, while the lower back is washed with 
white to about the same extent as is generally the case in 
N. canicapilla. The winter dress is apparently discarded in 
April, for the specimen procured by Dr. Ansorge at Kichuchu 
in Toru, April 5, 1899, is in breeding plumage. A very similar 
bird to the last mentioned was shot by Mr. Jackson in Nandi, 
July 2, 1898, and on the same day he killed a specimen with 
no trace of white on the upper surface of the wing. 
The type of N. sparsimguttata was procured at Bukoba, 
on the western side of Victoria Nyanza, by Emin, who also 
obtained specimens at Ipoto, Awamba and Irumu.
