Altlionijli I have never had one in my hand to examine, by a process of 
exchisioii T conclude that the bird my note refers to is cither aetfiiopicn or 
leiicdKdiita ; whichever it is, it is very ainiiidant, and well known here.

first four species of nirumh) on my list, in all of which the rump is blue-

Kai/i/p. Senegambia to Congo. North-east and Equatorial Africa 
(ILL.) 
This is the largest of our (Jambian .Swallows. JJuring half the year 
they are as plentiful as any in the Protectorate, but 1 have never seen them 
m Bathurst or indeed anywhere near the coast-line. They arrive about 
April or ]\Iay and begin to breed almost at once, making nests inside the 
native huts, using both inhabited and deserted ones, and not confining them- 
selves to the former, as do most of our other Swallows. Every year their 
arrival is (juite a noticeable event, as the}' reach us in large flocks, and at 
first, at any rate, always roost in company on the tops of dead or leafless 
trees : one day there are only the ordinary number of our resident Swallows 
about a place, the next the air is thick with the visitors, which are easily 
distinguished by their larger size (9 inches), chestnut bellies, long wings and 
deeply forked tails.

liaiiijc Senegambia to Angola. ( ILL.) 
Like >ii'iiei/alfi>ixis but much smaller and with a rufous instead of a 
a white throat. I noted in December. 1906, a white-breasted red-rumjied 
bird, smaller than the Senegal Swallow as being <iuite common at Riu-reng 
and elsewhere, which I think was this species : if so it must be a resident 
here.

This Rough-winged Swallow I have never to my knowledge met with. 
It is black glossed with green above and dull black below, and has very long 
wings finely serrated on the outer margins and a deeply forked tail. 
CYPSELIDAE. 
Ci/pxrhu a.pN.-<. COMMON SWIFT. 
RaiKjc Europe ; Africa in winter (H.L.) 
In January 1907, I saw a number of black Swifts at Sunkunda, one of 
our most easterly towns, which I feel sure were common Swifts, but I do not 
rcmembei' having seen any elsewhere or on any other occasion. Our most 
abundant Swift is the mouse-coloured bird, which I take to be the next 
species.
