Birds of Southern Cameroon . 
The eggs (Nos. 586, 587) measure 30 x 21 and 29 x 21 mm. 
One was nearly covered with adhesive dirt, looking like 
that left by termites, though it was a fresh egg. 
[Eggs Nos. 586 and 587 are of a regular oval form, 
slightly glossy; the ground-colour is creamy-white with small 
spots and rounded blotches of dark vandyke-brown and 
various shades of grey, mostly confined to the larger 
end.—O.-G.] 
Hirundo senegalensis. 
Reich. Y. A. ii. p. 415. 
No. 4300. S (testes rather large). Bitve, July 1910. 
This, the only specimen obtained, was shot with bow and 
arrow while it was getting clay on the path. The claws 
were remarkably sharp. 
Psalidoprocne petiti. [Nguleyebe.] 
Sharpe, Ibis, 1901, p. 621; 1907, p. 444. 
An immature bird. No. 4294 has the under side brown, 
quite light and greyish on the abdomen. No. 3508 has 
some greyish-brown feathers among the new black ones. 
No. 3954, a sitting female with two empty ovum-sheaths 
in the ovary, was brought to me with a nest, consisting of a 
pile of moss-like Usnea , and two white eggs. All were said 
to have been dug out of a hole in the side of a pit made to 
catch animals. The eggs have little gloss, and are very 
long, measuring 21 X 13 and 20 X 13 mm. respectively. 
When I was having clay dug from a pit for making bricks, 
three pairs of these little black Swallows were seen during 
several days, sailing close over the pit whenever the work- 
boys were away. They had probably begun excavating to a 
slight extent; if so, they never alighted to work, but took a 
mouthful of earth in passing—I could not be certain 
whether they did this or not. They always passed in pairs, 
and were often heard to utter a low <e weeping ” note. 
Usually these birds are perfectly silent.
