Laniarius bicolor. 
Dryoscopus bicolor, Hartl. Orn. W. Afr. p. 112 (1857) Gaboon; Gadow, 
Cat. B. M. viii. p. 138 (1883). 
Laniarius eethiopicus bicolor, Reichen. Vég. Afr. ii. p. 579 (1903). 
Adult. Resembling very closely Z. guttatus, but the inner secondaries 
entirely black or exceptionally with a trace of white only. Total length 
8-2 inches, culmen 0:95, wing 4:0, tail 3-5, tarsus 1-4. Gaboon (Du Chaillu). 
The Gaboon Boubou very closely resembles that of 
Angola but has lost the white edging to the secondaries. It 
was described by Hartlaub from an example in the Verreaux 
collection from Gaboon and appears to be confined to that 
region. ‘There are two examples in the British Museum from 
Du Chaillu’s and Walker’s collection, while Reichenow records 
it from 'T'schintschoscho in Portuguese Congo, but examples 
from this district in the British Museum have strong white 
edges to the secondaries and appear to be more nearly allied 
to L. guttatus.
