note of A. narina being a double, dove-like “cu-coo,” which is repeated 
slowly for several seconds, starting faintly but increasing in strength, and 
accompanied by a slight wagging of the tail. That of A. minus is a series 
of longer, more mournful sounds that might be represented by the word 
“kwaw.” These calls are given by the males. 
As compared with the measurements given in Prof. Reichenow’s “ Vogel 
Afrikas”’ and the British Museum Catalogue, our specimens of Apaloderma 
narina from the Ituri District seem rather small, and may belong to the 
race equatoriale of Dr. Sharpe. 
A series of 12 adult males measures: bill (culmen from base) 18.5-21 
mm.; wing 117.5-128; tail 146.5-166. The green borders of the second- 
aries are never very well marked, and sometimes virtually absent. 
Seven females from the same region measure: Bill, 18.5-21; Wing 117.5- 
129; Tail, 149-169. 
One male collected in the Uele District, in a small forest tract between 
Faradje and Aba, is strikingly larger; wing, 134; tail 194. This example 
is probably referable to A. n. narina.

Ceriocleptes gen. nov. (Indicatoride). 
Resembling Indicator in its bill and general form, save for the tail, which is com- 
posed of 12 quills, the two middle pairs of nearly equal length, somewhat pointed and 
curved strongly outwards, the next pair considerably shorter, but also pointed and 
slightly curved; while the fourth, fifth and sixth are straight, greatly narrowed, and 
stiffened, becoming successively shorter, so that the outermost pair is not half so 
long as the median. ‘The tail-coverts are unusually long, those below as long as the 
longest rectrices, and projecting in the fork of the tail.

Avakubi, Ituri District, Belgian Congo. Apr. 17, 1914. 
Feathers of forehead, crown, back, and rump blackish-brown, bordered or washed 
with yellowish-citrine, those of nape and upper back whitish at the base. Sides of 
head lighter, shading gradually to olive-buff on throat, breast, and sides; middle 
of abdomen still lighter, ivory-yellow. Upper wing-coverts and secondaries fuscous- 
black (freshly molted feathers blacker) narrowly edged with olive-ocher. Primaries 
similar, but yellowish border almost entirely lacking; both primaries and second- 
aries fading to pale olive-buff on their inner edges. Under wing-coverts colored like 
the breast, but with faint dusky shaft-streaks. Feathering of flanks ivory-yellow, 
with strong blackish median lines. Two middle pairs of rectrices dull blackish; 3rd 
pair whitish, with a small blackish spot on the outer edge close to the tip, and a larger 
concealed black spot on the inner web towards the base; the 3 remaining pairs of
