the adult male is taken from one of M. Verreaux's types of C.jardinei from the Gaboon, a more than 

 usually fine specimen, in Mr. Sharpens valuable collection of African birds. 



The present species, as here restricted, is exclusively confined to West Africa ; for I consider that 

 the specimens from the east and north-east portions of this continent which have been called 

 C.jardinei, belong to distinct races. 



There are really four very nearly allied forms, differing only in their measurements ; but 

 they each seem to have a distinct habitat. C. mariquensis is from South Africa, C. bifasciatus 

 from the west coast, C. microrhynchus from the Zanzibar district, and C. osiris from Abyssinia. 

 We cannot, as has been generally done, only select C. mariquensis and C. bifasciatus as good 

 species ; for C. osiris is so nearly intermediate between them, that it cannot be referred more 

 justly to one than to the other, while C. microrhynchus is the smallest, and quite as distinct from 

 C. bifasciatus as that bird is from C. osiris. 



The present species was first described and figured by Audebert and Vieillot from specimens 

 sent from Malimba by Perrein, and was afterwards renamed by M. Verreaux from Gaboon spe- 

 cimens. It is fairly plentiful in West Africa, ranging from the Gaboon to Benguela, and is 

 recorded by Mr. Monteiro as being very abundant in the latter locality, even in comparatively 

 barren places, and feeding upon little insects, especially small spiders. Professor Barboza du 

 Bocage, who has kindly presented me with a specimen from Loanda, has also recorded it from 

 Dombe, in Benguela, where, according to Sefior Anchieta, it is known to the natives by the name 

 of " Kanjongo." On the Loango coast it has been collected by Falkenstein.
