the statements of tlie natives. All my birds were sexed by 
myself alone. In speaking of objects and conditions peculiar 
to the African forest country, it has often been difficult' to 
find suitable English words, and it has been convenient to 
borrow a few words here from Bulu, my language when in 
Africa; they have mostly been used in * The Ibis' before. 
(Pronounce the vowels as in French.) Ejak means a company 
of birds in the forest (see e Ibis/ 1905, p. 462); ekotok , plural 
bikotok, means old cultivated or cleared land, now abandoned 
and overgrown thickly with almost impenetrable bushes, 
vines, tall sedges and grass, and small trees; engas means 
the swampy border of a stream, overgrown with sedges and 
w r eeds; njak is the name of an ants' nest hanging in a tree, 
and also of a suspended termites' (white ants') nest. Names 
of trees and plants used are:—“aseng," Musanga smiihii ; 
“aboe," Alcornea cor data ; “ atondok," Haronga sp.; “okdng,” 
Triumfetta sp. ; “ esong," Panicum maximum. 
Much more is due to Mr. Qgilvie-Grant in this paper than 
his brief descriptions of the eggs, and I am under great 
obligations to him. I must also thank the officers and 
attendants of the “ Bird-room " in the Museum for much 
courteous help. 
The arrangement followed is mostly that of Prof. Eeich- 
enow's “ Vogel Afrikas."

This specimen is the only one that I have seen, and it was 
new to the boy who shot it and to the people of the village. 
But a man from another village nearer the Ja knew the bird 
and gave me the Bulu name for it; so probably it is not 
very rare on the Ja itself. The boy who shot my specimen 
said that he saw it on a log over the small river near 
Bitye, with its wings spread out, sunning itself. When shot 
and wounded it dived into the river out of sight and emerged 
far away.
