610 MR. R. B. SHARPE ON THE BIRDS OF CAMEROONS. [June 20, 



Mr. Crossley has sent a male of this lovely bird, which agrees 

 exactly with one of the type specimens in my collection, given to me 

 by my good friend M. Jules Verreaux himself. 



Fam. Muscicapid^e. 



36. Bias musicus. 



Bias musicus (V.); Sharpe, Cat. Afr. B. p. 43. 

 "Cameroons Mountains, February 23rd, 1871." 

 A male in full plumage. Megabias seems to me to be scarcely 

 generically separable. 



37. Platysteira leucopygialis. 



Platysteira leucopygialis, Fras. ; Sharpe, Cat. Afr. B. p. 43. 



"Eye blue." 



Mr. Crossley has sent several specimens of this bird, procured on 

 the Cameroons Mountains, between the 18th of January and the 27th 

 of February. 



38. Platysteira cyanea. 



Platysteira cyanea (Mull.) ; Sharpe, Cat. Afr. B. p. 44. 

 An old male, and a young male just throwing off the plumage of 

 the adult female. 



39. Terpsiphone tricolor.

 Mr. Crossley has sent a fine series of this Flycatcher, procured 

 between the 21st of January and the 5th of February, 1871. 



40. Terpsiphone melampyra. 



Terpsiphone melampyra (Verr.) ; Sharpe, Cat. Afr. B. p. 44. 



Two specimens procured on the Cameroons Mountains on the 

 16th of February, 1871. This species appears to me to be clearly 

 characterized, the absence of white on the wing being the distinguish- 

 ing peculiarity. I have a fine specimen in my collection from 

 Gaboon. 



Fam. Hirundinid^e. 



41. Psalidoprocne nitens. 



Psalidoprocne nitens (Cass.) ; Sharpe, P. Z. S. 1870, p. 291. 



"Cameroons Mountains, January 16th, 1871." 



Until recently this species was known only from Gaboon, where 

 it was discovered by Du Chaillu, one of whose original specimens is 

 now in my collection. Governor Ussher has lately sent it from 

 Fantee, and the discovery of the bird in Cameroons shows that it is 

 found in all the countries round the Bight of Biafra.
