the species considerably to the northward. Like others of this group it is prob- 
ably a bird of thick growth, seldom seen. 
Phyllastrephus icterinus (Bonaparte). Yellow-bellied Bulbul 
Trichophorus icterinus Bonaparte, Conspec. Avium, vol. 1, p. 262, 1850: ‘‘Guinea.” 
Length 6 inches; top of head, the wings and back bright olive green; upper tail-coverts washed 
with rusty; tail reddish brown, the outer edges narrowly olive green; inner edges of wing-feathers 
pale buffy; throat, middle of breast, and belly bright yellow, flanks olive; iris buffy. Liberia to 
Gaboon. 
This is a thicket dweller, of inconspicuous coloration, and difficult to find. 
We secured single specimens on the Du and at Paiata on the St. Paul’s River, 
one of them with the remains of a large caterpillar in its stomach. Biittikofer 
records but one, taken ‘“‘in brushwood”’ near Hill Town. This is the Pycnonotus 
tricolor of Chubb’s list. 
Phyllastrephus leucopleurus Cassin. White-bellied Bulbul 
Phyllostrophus leucopleurus Cassin, Proc. Acad. Nat. Sci. Philadelphia, 1855, p. 328: Moonda 
River, West Africa. 
Size of a mockingbird, 10 inches; above olive brown, grayer on head; chin white, throat and 
breast olive, the feathers with gray central streaks; belly and under tail-coverts white, washed with 
yellow; tail like the back but the four outer feathers on each side with broad white tips. Sene- 
gambia to Congo. 
This fine vigorous bird is common along waterways and especially in swamps 
with a dense growth of jungle mixed with Raphia palms whose roots prefer water 
to stand in. They are excellent singers and especially toward evening keep up 
a loud conversational type of song from the thickets. At one place on the Du 
River we saw three in pursuit flight, but as on other occasions, they dashed 
instantly for shelter on perceiving us. 
Baeopogon indicator (J. and E. Verreaux). White-tailed Bulbul 
Criniger indicator J. and E. Verreaux, Journ. f. Orn., vol. 3, p. 105, 1855: Gaboon. 
Size of a small thrush, 7.5 inches; above, olive green, sides of head and throat blue-gray, the 
breast similar but with an incomplete band of olive green; belly pale buff, flanks olive; central tail- 
feathers blackish, the four outer ones white with brownish-black tips. Iris buffy. Sierra Leone 
to Congo. 
This is a forest species, of which we saw but a single pair at Bonuta and 
secured the male. One bird was pursuing the other among the branches of the 
forest trees at some fifty feet from the ground. Biittikofer records it from Schief- 
felinsville, Junk River, and from Jarjee, Marfa River, and notes that the male 
is the larger. Lowe procured it on the south coast at Settra Kru.
