This Sun-bird may be recognized by the entire absence of all metallic colours and by the bright 

 sulphur-yellow pectoral tufts, which are present in the adult of both sexes. It is most nearly 

 allied to the South-African C. olivaceus, from which species it is distinguished by the underparts 

 being whitish, the pectoral tufts much paler yellow, and the basal half of the lower mandible 

 buff. 



It is a native of West Africa, where it ranges from the Gold Coast to Angola, and is found 

 on Prince's Island and Fernando Po. On the latter island the type was collected by Eraser, 

 who also procured it from the Niger district ; and from Prince's Island we have examined 

 specimens collected by Ingall, Keulemans, and Petit ; the latter specimen, which is in my own 

 collection, is labelled " male," while the female, which I have here figured and described, was 

 also collected by Petit at Bonny. 



Mr. Keulemans writes to me, that when he was in Prince's Island he met with this species 

 " only in the dense forests, where, owing possibly to the thickness of the undergrowth and 

 creepers, it was rarely to be seen. The high trees in the more retired parts of the forests are its 

 favourite haunts ; and it is seldom observed near the ground, excepting when the aroma of the 

 ripening fruits attract it towards the plantations, where it may at such times be occasionally met 

 with around the banana and papaya plants. Its song, which it constantly utters, is totally unlike 

 that of C. hartlaubi, being a more guttural sound, like ' hoo-hoo-hoo ' rapidly repeated ; but its 

 call-note is a soft \foo-cet,' and can hardly be distinguished from that of C. hartlaubi. 



" It is known on the island by the name of ' Siwie-barbeiro grande.' " 



On the Gold Coast it is a very common species, but apparently more abundant in the dense 

 forests of Denkera than towards Cape-coast Castle. While in the Aguapim district I met with 

 it along with many other species in the tall flowering trees ; but as we only obtained a single 

 specimen at Abouri, I presume that it is not so abundant there as many of the other species of 

 Sun-birds. 



We have examined specimens in the British Museum from the Camaroons and the Gaboon, 

 in which latter locality it has been collected by Du Chaillu on the Muni and Camma rivers, and 

 by Marche and De Compiegne on the Ogowe. From Angola it was first recorded by Verreaux, 

 and has since been collected there by Mr. Hamilton. 



The immature bird above figured and described was collected for Mr. Sharpe in Fantee, and 

 is now in the British Museum with the rest of his Sun-birds.
