half the length of the feathers, of a bright steel blue, dusky beneath. The 
under tail coverts are of the same^ colour as the tail. The length of the 
bird is eight inches and three quarters; the bill being an inch long, consi- 
derably bent, and black. 
No. 29. Tanagra eryfhroryncha. Red-billed Tanager. 
In size and manners, in the arrangement of the feet, and the general 
colour of the plumage, this bird strongly resembles the African Beefeater, 
but the form of the bill is manifestly different, being three quarters of an inch 
long and of a bright orange red, strong in shape, but not straight or square. 
The upper mandible is convex, a little inclining at the point, with no notch, 
but the edges are a little protuberant at the base below the nostrils, the 
lower one being flat at the sides and having an angle on the lower side. 
The general colour of the plumage on the upper parts, the throat, and 
neck, is a heavy olive brown shading off at the ends of the quills into dusky, 
except in some of the primaries, the ends of which are of a lighter brown, and 
the lower parts of brownish yellow. The tail appears rounded in shape, 
the feathers being somewhat pointed, but there is no rufous colour on the 
inner margins. The legs and claws are brown : the rump is of the same 
colour with the upper parts, and the tail rather more dusky. The front 
feathers come forward on the bill and half shade the nostrils, which are 
covered by a yellowish membrane, the aperture in which is very small and 
close to the feathers. I have ventured to give this bird the above name, 
in which I have more confidence, as I herein follow the example of our 
ablest ornithologist, Dr. Latham. If the Buphaga is unknown in Abyssinia, 
this must be a new bird, and, though not precisely answering to the 
generic characters of Tanagra, may as well remain attached to that genus, 
at least wdiile our present uncertainty about it lasts.* 
No. 3T. Sylvia pammelaina. All-black Warbler. 
The length of this bird is rather above seven inches, of which the tail 
takes up full three and a quarter. The bill, is half an inch in length and 
blackish, the upper mandible inclining a little, to wards the point, and having 
^ I saw vast numbers of them^ and they had all invariably a red bill, H. S.
