and throat white, with a dark triangular patch of feathers in front of the eye ; chest, abdomen, flanks, 

 thighs, and under tail-coverts pale yellow ; under surface of the wing as in the adult male, only the 

 coverts are slightly tinted with yellow. Length 5 inches, culmen - 65, wing 2'4, tail l - 8, tarsus 07. 



Hab. Tropical West Africa. 



The characters which will at once distinguish this species are as follows : — The bill is straight, as 

 is usual in the genus Anthreptes ; the upper parts in both sexes are metallic green ; in the male 

 the chin and throat are metallic green, not terminating in a steel-blue collar, the breast huffish 

 white, and the pectoral tufts reddish orange. In the female the sides of the head, chin, and 

 throat are white, chest and abdomen pale yellow. 



An immature specimen of Anthreptes, formerly in Mr. Sharpe's collection, and now in the 

 British Museum, from Fernando Po, labelled as a female of Cinnyris obscurus by M. J. Verreaux, 

 I refer to this species. It has the upper parts olive shading into ashy brown on the crown and 

 forehead ; wings and tail brown with olive-yellow edges to the feathers ; sides of the head, chin, 

 and upper half of the throat ashy white ; remainder of the underparts pale yellow ; under surface 

 of the wings brown, with the inner margins of the quills and the coverts white, the latter slightly 

 tinted with yellow. Total length 4T inches, culmen 0-65, wing 2T5, tail T4, tarsus 0'65. 



This beautiful and very rare Sun-bird is a native of tropical West Africa, where, as far as 

 we know, it is confined to the Gaboon and Cameroons districts and to the island of Fernando Po. 

 Its occurrence in Fernando Po rests upon the immature specimen above referred to. Owing 

 probably to the latter being a female, it differs considerably from the immature male described 

 by Mr. Cassin. " Upper parts dull yellowish green, underparts pale yellow, tinted with very 

 pale ash on the throat, very distinct stripe of pale yellowish white through the eye, tail metallic 

 green, outer feathers tipped with dull white." 



On the Cameroons it has been collected by Mr. Crossley, near Victoria Forest, at the end of 

 January. 



Verreaux' s type came from the Gaboon, where Du Chaillu also collected specimens on the 

 Camma and Ogobai rivers ; and Marche and De Compiegne procured it also in that district ; but 

 nothing with regard to its habits has yet been recorded. 



The adult birds we have figured and described from the specimens in the British Museum — 

 the male coming from the Cameroons, and the female from the Gaboon.
