When it is remembered that Mr. Lowe spent under three 
months in the Colony, the fact that he could procure or 
identify without a doubt thirty-two birds, which, despite the 
labours of Mr. Robin Kemp, Major Kelsall, and others, 
had never previously been recorded from Sierra Leone, 
speaks volumes for the work still to be done in West Africa, 
and not a little for the untiring energy and discrimination 
with which Mr. Lowe faced his task. 
Special mention must here be made of* the new Giant 
Swift, which Mr. Lowe discovered. A single specimen 
was shot at Mahera up the Rokelle River (see Map), 
and Mr. Lowe tells me that this Swift was very common in 
the neighbourhood of the village, and had he had more than 
one cartridge he could have secured a fine series. The 
birds were nesting at the time of his visit, 21 April. The 
discovery of this bird in Sierra Leone is of very special 
interest, as hitherto no specimen of any race of the Giant 
Swift has been obtained in this part of Africa. The 
typical species inhabits Abyssinia and probably extends 
south through the great lake.^. More than one race has been 
described, and, almost at the same time as Mr. Lowe shot his 
bird, Capt. Hubert Lynes, R.N., procured y'et another race 
in Darfur in almost the same latitude as Sierra Leone. 
I have already described M. ce. lowei at length in the 
‘Bulletin’ of the, Brit. Orn. Club, vol. xli., October 1920, 
p. 2. Additional specimens are badly needed in the British 
Museum. The bird cannot be mistaken for any other Swift, 
as the wing measures 204 mm. 
Another bird of very great interest, which does not strictly 
come within the scope of this paper, may, nevertheless, well be 
mentioned here. It is a small Rail which flew on board 
* Not obtained, but identified without a doubt.
