Cypselus horus, H. et F. 541 



Antinori and I have identified with C. Jiorus. The young 

 specimen in Count Turati's collection is smaller than the 

 adult specimen in the Museum of Turin (long. tot. 140 millim., 

 al. 124, caud. rectr. ext. 58) ; it has the feathers of the crown 

 and the quills edged with whitish, and the white on the throat 

 and rump a little greyish. 



M. Bouvier has described and figured under the name of 

 Cypselus sharpii^ a bird from Banane (Congo), near Lan- 

 dana ; and I have not the least doubt that the specimen which 

 he has sent now to Count Turati belongs to that species, 

 which I identify with C. horus. His description of C. sharpii 

 agrees with that of C. horus ; only the dimensions are smaller, 

 most likely from the specimen described being not fully grown. 

 A little later Messrs. Sharpe and Bouvier-f have stated that 

 " C. sharpii a de grandes affinites avec Cypselus horus, mais en 

 est parfaitement distinct ;" but they do not say what the differ- 

 ences are, and I have failed to discover them myself. 



Again, Prof. Barboza du Bocage, in his valuable work the 

 ' Ornithologie d^ Angola,^ gives the description of a Cypselus 

 finschi from Angola, which I am sure is the same as C. horus 

 and C. sharpii. It seems that even Prof. Barboza had recog- 

 nized that his bird was the same as C. horus, so that I do not 

 quite understand why he should have given it a new name. 



After the above identifications the synonymy of C. horus 

 will stand as follows : —
