Hylia prasina prasina. 



Sylvia prasinn Cassin., Proc. Ac. Se, Philad., 1855, p. 325. — 

 Type locality : Moonda river. 



Mr LowE shot two spécimens of Cassin's Tree-warbler at Iju in 

 December and January 19 19-1920; in Mr Kemp's collection there 

 is one bird from Burutu obtained in April. 



The verv varied plumage exibited bv this wide-ranging species 

 is discussed at length by Mr Ogilvie-Grant in the Ibis, 1908, 

 pp. 292-293. 



Range. — We hâve a large séries of the Continental Tree- 

 warbler in the British Muséum from Portuguese Guinea, Sierra 

 Leone, Libéria, Gold Coast, Southern Nigeria, Cameroon, Fer- 

 nando Po, Gaboon, N. Belgian Congo, French Equatorial Africa 

 and Uganda. 



I can onlv recognise the tvpical race on the Mainland of 

 Africa, but I believe the race separated by Boyd Alexander 

 from Fernando Po should be recognised, we shall therefore hâve : 



1. — Hylia prasina prasina. 

 Cf. supra. 



2. — Hylia prasina poensis. 



Hylia poensis Alexander, Bull. B. O. C, XHI, 1902, p. 36 : 

 Rebola, Fernando Po. 



Range. — Fernando Po. 



Distinguishing ckaracters. — Upper-parts of adults distinctly 

 darker; crown of head browner; Eye stripe more pronounced and 

 lighter. 



(A fairly common species found in the bush and also in large 

 trees. It has a curions habit of jerking its wings and uttering notes 

 somewhat like a Honey-guide. — W. P. L.)
