plumes. I was surprised when I saw Dr. Sharpe's paper to 
find what they were. The natives about Bitye certainly know 
nothing of the remarkable plumage of the breeding males. 
My specimens were shot in March, just at the end of the dry 
season and only in 1906; the bird has not been seen again. 
I think some of them must have been in that neighbourhood 
on a temporary sojourn, perhaps driven by the dry weather 
from the region further north or north-east. According to 
a trader, who had been in Bertua, far to the north-east of 
Bitye, where there is little forest, this bird lives and breeds 
there. 
934. Cmtura sabinii. 
No. 2511. S- Bitye, May 15, 1907. Testes large. 
Iris brown ; feet bluish. 
This specimen was caught alive by a man who said that 
it and another one Hew into his house ! Some white-rumped 
Swifts have been several times seen coursing in the air, and 
were doubtless of the same species. 
966. Hirundo gordoni. [Ngomeko.] 
Sharpe, Ibis, 1907, p. 444. 
A note on this Swallow has already been published 
(‘ Ibis/ 1905, p. 467). Birds of this species are seen oftener 
than anywhere else about deserted village sites, especially 
those along the road to the coast. Here there is not enough 
stir of human life to scare them away, and yet there is the 
open space and the bare ground that they like. On a trip 
to Ebolwoa in December 1906, I saw two of these Swallows 
fly close over the bare ground of such a place, and perch 
on a plantain along the path. Then one of them was 
heard to sing , uttering a trill in a low, but very sweet voice, 
its throat swelling much at each utterance. This it repeated 
and continued to do so as long as I stood and watched. Its 
mate was perched not more than three feet away. 
971. Hirundo nigrita. 
Specimens of this Swallow were shot on the water of 
the River Ja, or the small River Libi, where it joins the Ja,
