86 Mr. W. R. Ogilvie-Grant on some recent [Ibis, 



Hab. I have examined examples from Natal (typical). 

 Portuguese East Africa, Rhodesia^ and Katanga, northwards 

 to Ankole and British East Africa ; also via the Zambesi 

 to Damaraland, Benguela, as far north as Canhocja in the 

 southern part of the Loanda district of Angola, where it 

 meets with the following form M. c. cinerea. 



Muscicapa cserulescens cinerea (Cassin), 



Eupsaltria cinerea Cassin, Pr. Ac. Philad. 1856, p. 253 

 [Moonda River, Gaboon: Du i'hai/lu]. 



? Muscicapa modesta Hartl. Orn. W. Al'r. p. 96 (1857) 

 [Gaboon] ; Bocage, Journ. Lisb. ii. p. 43 (1870) [Mossa- 

 medes] . 



Hypodes cinerea Cassin, Proc. Ac. Philad. 1859, p. 52 

 [same type as above]. 



Muscicapa cassini Heine, J. f. O. 1859, p. 428 [founded 



on Muscicapa ? Cassin, Pr. Ac. Philad. 1859, p. 51, 



Camma River, French Congo] . 



Muscicapa cinerascens Sharpe, Cat. Birds B. M. iv. p. 155 

 (1899) [Fantee: Ussher'\. 



Muscicapa brevicauda Ogilvie-Grant, Bull. B. O. C. xix. 

 p. 107 (1907) ; Ibis, 1908, p. 308 [Upper Congo]. 



The British Museum contains typical examples of E. 

 cinerea Cassin, collected by Du Chaillu on the Moonda River, 

 Gaboon. These birds agree perfectly with Cassin's descrip- 

 tion, as also with the type-specimens of M. cinerascens 

 Sharpe and M. brevicauda Ogilvie-Grant. 



Mr. Witmer Stone ('Auk,' 1914, p. 255) asserts that the 

 present subspecies, M, c. cinerea Cassin, is synonymous with 

 M. luyens Hartlaub, but this is an error, for the type-speci- 

 men of the latter species is in the British Museum, and is a 

 perfectly distinct form, with no white lines of plumes above 

 and below the eye, and without wiiite edges to the primary 

 quills. For remarks on this matter, see Stone, Pr. Ac. Philad. 

 1889, p. 147 ; and Stone, ' Auk,' 1914, p. 255. 



M. c. cinerea is a rather smaller more northern and 

 western representative form of M. ccerulescens with a pro- 

 portionately shorter tail.
