Hartlaub’s Black-crowned Waxbill ranges over Kquatorial 
Africa from Camaroons into the Upper Congo, and eastward 
to Nandi on the Kquator in about 35° 30’ EH. long. 
In Camaroons both this species and its near ally, 4. atricu- 
pula, occur, the latter towards the coast, and is probably 
entirely replaced inland by this more highland form, which 
has been met with by Dr. Preuss at Buea and by Mr. Zenker 
at Jaunde. Mr. Sjéstedt found it at Bibundi only, but here 
it was abundant and in large flocks, frequenting the grass- 
lands and perching on the scattered small trees and bushes, 
or seeking seeds on the ground. 
In the Upper Congo district Jameson procured three 
specimens at Yambuya, and Bohndorff the type of Habropyga 
tenerrima, Reichen., at Stanley Falls. Between this and the 
Victoria Nyanza it has been met with by Mr. Scott Elliot 
at the Albert Edward Nyanza, and by Emin at Bokober and 
as far south as Karagwe. ‘The most eastern range yet known 
for the species is Nandi, where Mr. Jackson collected five 
examples in the forest, at an elevation of 6,000 to 6,500 feet. 
Emin found the species in the Unyoro, Uganda, and 
Mombuttu countries, and discovered the type at Kudurma. 
According to his notes (J. f. O. 1889, pp. 46-49), the species 
selects wooded localities interspersed with glades in preference 
to the grassy plains or the rank vegetation of the river-banks, 
and is mostly seen in family parties of six or seven, flitting 
from bush to bush, or creeping through the foliage, descending
