underside apparently less bright yellow, and the blackish 
lines on the jugulum a little more distinct. Wing 83, 
* culmen 15°5 mm. 
Hab. Maktan, British East Africa. 
Type. & ad. Maktan, 18.9.1915. Capt. Angus Buchanan 
leg. No. 1. 
A nest with three eggs was found at Maktan on Septem- 
ber 26th, 1915. The nest is evidently somewhat flat and 
composed of fibres, rootlets, little twigs of herbaceous 
plants and spiders’ webs, and vegetable wool. The three 
eggs resemble closely those of the Trumpeter Bullfinch 
(Erythrospiza githaginea), being pale blue with purplish- 
black dots and occasional short lines. They measure 
20 x 15:1, 19°5 x 14°9, and 19°2 x 15 mm. 
This new form is undoubtedly a near ally of Serinus 
donaldsoni Sharpe, from Somaliland, but it differs from the 
latter in having a much larger, thicker, and less curved 
bill and longer wings, the upperside is more yellowish, 
less greenish, the sides less green. I have compared the 
type and several other specimens in the British Museum. 
Probably 8S. donaldsoni is restricted to Somaliland, and 
S. buchanani may be its representative in East Africa. 
Reichenow mentions a specimen collected in Ugogo by 
Emin Pasha, which agrees with Sharpe’s description of 
S. donaldsoni, but as he did not compare the type it is 
possible that the Ugogo bird is buchanani. The species 
is named after its discoverer, who collected one male, one 
female, and the nest with eggs. 
Mr. Cuartzs Cuvss sent descriptions of the following
