THE BIRDS OF LIBERIA 723 
Readily distinguished by its greenish coloration and the yellow spot at the 
ends of the tibiae, this is one of the common small species of thick undergrowth 
in forests or along their borders, but is not easy to see or collect on account of 
the difficulty of finding it in such places. C. brevicaudata of Biittikofer’s lists 
and C. chrysocnemis of Bannerman are the same species. A young male taken 
at Moala, November 2, differs from the adult in being dark olive green above 
and washed with yellow below. Its tongue is yellow with two oval black spots 
at the beginning of the basal third, touching medially. The specimens secured 
do not seem different from Cameroons birds to which the name tincta is currently 
applied. 
Camaroptera concolor Hartlaub. Olive-green Warbler 
Camaroptera concolor Hartlaub, Syst. Orn. West Afr., p. 62, 1857: Guinea. 
Size of the preceding but entire plumage olive green, the lower side slightly paler and yellower; 
wings and tail olive brown edged with greenish olive; a yellow mark at the edge of the wrist; 
bill horn color, the lower mandible paler. West Africa. 
Like C. g. tincta this is a thicket-loving warbler, found in dense bushy growth 
along the forest paths or in the under story of second growth. We were unable 
to detect any difference in the habits of the two. A female taken at Paiata, 
October 13, was about to lay eggs. Biittikofer records it from Mt. Olive, Paynes- 
ville, and Robertport, and we secured specimens at Gbanga, Paiata, and Banga. 
Camaroptera flavigularis Reichenow. Yellow-throated Warbler 
Camaroptera flavigularis Reichenow, Orn. Monatsb., 1894, p. 126: Cameroons, Yaunde. 
Length 4 inches; above olive green, wings and tail dusky brown, edged with olive green; a 
narrow eyebrow-stripe, the cheeks, throat, under tail-coverts, and a spot near the bend of the wing 
bright yellow; belly white, ends of tibiae yellowish olive. Cameroon region. 
A single immature female taken at Paiata, October 6, seems to represent 
this species, and would thus extend its known range into Liberia. 
Stiphrornis erythrothorax Hartlaub. Orange-throated Warbler 
Stiphrornis erythrothorax Hartlaub, Journ. f. Orn., vol. 3, pp. 355, 360, 1855: Gold Coast, Dabo- 
crom. 
A short-tailed warbler-like bird; olive brown above with a small white mark in front of the 
eye, dark slaty-gray cheeks, orange throat, belly and under tail-coverts pale yellowish, sides washed 
with olive gray. Liberia to Togo. 
Biittikofer (1888, p. 74) obtained this species on the Junk and Du rivers in 
thick brushwood and undergrowth of low forest. He describes its song as soft 
and agreeable. Dr. Linder procured a male at Totokwelli, October 28, in a 
thicket beside a forest path. It was singing softly as it hopped about in the 
dense cover very near the ground. It is apparently an uncommon species. 
Sylvietta stampflii Biittikofer. Short-tailed Warbler 
Sylvietta stampflit Biittikofer, Notes Leyden Mus., vol. 8, p. 252, 1886: Monrovia, Liberia. 
Length about 3 inches, tail very short; crown brownish gray, body olive green, wings darker; 
eyebrow stripe and cheeks yellowish brown; throat, breast and belly white, sides brownish gray. 
Liberia.
