360 CHAUNONOTUS SABINI 
typical subspecies in its somewhat larger size, and especially in the broader 
bill averaging 0°30 to 0:35 across at the nostrils, against 0:25. Wing 3-45, 
tail 2:9, culmen 1:05. River Ja, 2. 2. 06 (Bates). The female has the 
mantle slightly darker than that of the female of the typical subspecies, and 
the tail dark ochraceous brown instead of brown with a rufous tinge. 
Wing 3:2. Efulen, 17. 7. 05 (Bates). 
This species ranges from Sierra Leone to the Congo, and 
can be separated into two races :— 
D. sabini from Sierra Leone to the Gold Coast Colony. 
D. s. melanoleucus from Camaroon and Gaboon. 
The type of the species, an adult male, was procured by 
Captain Sabine at Sierra Leone many years ago, and is still 
in the British Museum. In the same colony it has been met 
with by Robin Kemp. 
In Liberia the species has been recorded from several 
localities by Biittikofer, and from the Gold Coast Colony by 
Ussher, Pel, Riis, and Alexander. Ussher states that it 
keeps chiefly to thick forest. 
The type of the southern subspecies came from Gaboon, 
where it is also said to be confined to thick forest. It has 
been collected by Du Chaillu, on the Muni and Kamma rivers, 
and by Marche, at Dumé, in the Ogawe district ; while Bates 
has sent a fine series to the British Museum from Camaroon, 
which enabled Sharpe to point out the difference between the 
two subspecies. 
The following is a list of the examples in the British 
Museum :— 
C. sabini—Sierra Leone (Sabine, type), Bo (Kemp); Gold 
Coast Colony, Fantee (Ussher), Accra (Haynes), Wassam 
(Blissett), Prahsu, Kwisa (Alexander). 
C.s. melanoleucus—Cameroon, Efulen and River Ja (Bates) ; 
French Congo, Como River (Bates), Gaboon (Walker) ; Portu- 
guese Congo—Irendo (Bouvier).
