it from Casamanse; Demery met with it along the Sulymah 
River, and Mr. Biittikofer in Liberia, frequenting the Bush near 
Fisherman’s Lake in Monrovia and on Mount Olive. The type 
is a specimen in the Bremen Museum from the Gold Coast. 
The species appeared to me to be abundant in the forests 
surrounding Abrobonko and Abouri. Aubinn procured it in 
the Denkera forest, and Ussher met with it during an expedi- 
tion up the Volta River, which is the most eastern range known 
for the species.

The Southern Chestnut-breasted Negro-Finch ranges from 
Prince’s Island and the Niger into the Congo district, eastward 
to Uvamba. 
This form may be regarded as a subspecies of N. bicolor, 
but its characters, though slight, are very constant. On 
Prince’s Island it has been procured by Mr. Keulemans, who 
found it to be “of a solitary, shy nature, frequenting the 
rivulets and mountain streams, disappearing quickly in the 
rank vegetation when disturbed. Its song resembles that of 
the Yellowhammer (Hmberiza citrinella). It is known by the 
natives as the ‘ Liwi-gigon.’ The males have the iris bright 
cherry-red, in the females it is pale brown.” Specimens have 
been obtained in the Lower Niger district by Dr. Ansorge.
