23? 



Although this pretty little Sun-bird has long been known to science, our information 

 respecting it is limited to the mere skins. 



Its range in West Africa extends from Senegal to the Gaboon ; and it appears to be most 

 abundant towards its northern limits. Swainson's type came from Senegambia. 



I have examined specimens collected by Marche and De Compiegne from Dakar, Hann, 

 Joal, and Sierra Leone, and M. Verreaux's specimens from Casamanse and Bissao. On the Gold 

 Coast it is rare, or confined to certain localities ; for Dr. Eeichenow was the first person to record 

 it from the Aguapim Mountains ; but it is apparently not so uncommon in the Lagos district, 

 for Mr. Henry Robin sent home three specimens from Abeokuta. Our descriptions and figures 

 are taken from an adult male from the Gaboon and a female from Sierra Leone, both from the 

 collection of M. J. Verreaux, by whom they were given to Mr. Sharpe. On the same illustration 

 we have figured the adult male of the closely allied 0. affinis. These three specimens are now 

 in the British Museum.
