694 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Biittikofer regarded them as active, quarrelsome birds and records that they 
feed on small fruits of several kinds. Furthermore, they seem to show a remark- 
able colonial habit, for he found them nesting in small colonies of from four to 
ten pairs, making nest-holes in dead wood. Sometimes as many as three to six 
pairs would be found with holes in the same trunk. 
Buccanodon duchaillui (Cassin). Yellow-spotted Barbet 
Barbatula duchaillui Cassin, Proc. Acad. Nat. Sci., Philadelphia, for 1855, p. 324, 1856: Moonda 
River, Gaboon. 
Length 6 inches; forehead red, throat black, a yellow stripe behind the eye; rest of body above 
black, spotted with yellow; wings and tail black; wing-coverts edged with yellow; breast and 
belly barred yellow and black, clearer yellow medially. Liberia to Lower Congo. 
This is a bird of heavy forest and apparently rare. Biittikofer secured only a 
single pair in all his collecting in Liberia, while Stampfli obtained a single male on 
the Junk River. Oberholser records a third male from Mount Coffee, and Lowe 
obtained it at Nana Kru. All these localities are near the coast, but Whitman 
was fortunate enough to collect a fine male at Tappi Town near the eastern 
border on September 30, 1926. Many of the barbets seem to be rather lethargic 
in manner, going about in pairs. Thus Biittikofer speaks of the pair he saw as 
perching ‘‘side by side upon a twig” in a high forest tree. 
Pogoniulus erythronotos (Cuvier). Red-rumped Tinker-bird 
Bucco erythronotos Cuvier, Regne Anim., ed. 1, vol. 1, p. 428, 1817: Africa. 
Small, about 4.5 inches long; above shining black, the rump red; a pale yellow eyebrow stripe, 
a similar stripe over the ear region, and a third from mouth across cheeks; a white band at base of 
bill; tips of middle wing-coverts yellow forming a bar; below yellowish. Senegal to Ruenzori and 
Portuguese Congo. 
The only records are of three taken at Schieffelinsville and one at Jarjee 
recorded by Bittikofer (1888, p. 95) as Megalaema atroflava. 
Pogoniulus subsulphureus chrysopygus (Shelley). Gold Coast Yellow-throated 
Tinker-bird 
Barbatula chrysopyga Shelley, Ibis, ser. 6, vol. 1, p. 477, 1889: Gold Coast. 
Small, length about 3.5 inches; black with whitish eyebrow stripe; rump, tips of wing-coverts, 
and edges of wing-feathers pale straw yellow; throat whitish, rest of under parts yellowish. Gold 
Coast to Liberia. 
Like the preceding, this seems to be an uncommon species of the forest 
growth. Biittikofer found it, however, in the forests behind Monrovia, and 
secured three at Schieffelinsville and on the Farmington River, as well as others 
at Robertport, indicating a general distribution. Lowe secured a single speci- 
men at Nana Kru, January 7, 1911. 
Pogoniulus scolopaceus scolopaceus (Bonaparte). Speckled Tinker-bird 
Xylobucco scolopaceus Bonaparte, Consp. Avium, vol. 1, p. 141, 1850: Ashanti. 
Small, length 4.5 inches; black above, the feathers edged with olive yellow; throat white, rest 
of under side pale yellow, becoming gray at sides. Liberia to Calabar.
