DRYOSCOPUS GAMBENSIS 345 
synonyms of Swainson and Hartlaub were received from 
Senegal. In the southern part of its range the females differ 
from those of the west coast proper in their much richer 
coloration and form a distinct subspecies, as has been shown 
by Sharpe. 
In the Gambia Colony this Puff-back has been collected by 
Randall and Budgett, in Sierra Leone by Fraser and Afzelius, 
in Liberia by Biittikofer and on the Gold Coast by various 
collectors, such as Ussher, Blissett and Riis, while in the 
interior of that colony it has been obtained by Colonel 
Northeutt and Alexander; the latter also collected this 
species in several localities in northern Nigeria. Reichenow 
notes it from Camaroon, where it has been met with by other 
German collectors, though it does not appear in the list of 
Mr. Bates’s birds. Further south Falkenstein, and Lucan and 
Petit have taken the more brightly coloured race in the 
Portuguese colony of Cabinda north of the Congo, and 
Bohndorff at Manyanga and Leopoldville on the Congo. 
Hartert, who obtained examples at Loko on the Benué 
River, found caterpillars and dung beetles in the stomach 
and observed it pursuing small birds with evil intent, while 
Alexander (Ibis, 1902, p. 312) writes: “‘ Breeds in April. The 
call of this species is loud and flute-like. We observed it 
frequenting acacia-trees and picking off the young shoots with 
avidity. It is common, but found only outside the forest- 
region.”
