19170 Collections of Birds from Cameroon. 87 



Dr. Reicheuow lias united Al. c. cinerea (= J/, ciiierascens 

 Shnrpe) with M. cofrufescens Hartl., but the former is easily 

 recognised by its proportionately shorter tail, and by otlier 

 differences. 



Wing : ^ 70-75 mm. ; ? 68-71 mm. 



Birds from N'JDalla Tando, in the northern part of the 

 Loando district of Angola, are somewhat intermediate, 

 having the tail relatively slightly longer than in typical 

 M. c. cinerea (tail, 2 ^ oG, 5^1 mm. and 2 ? 52, 51 mm., as 

 compared with J" 50-53 mm. and $ 48-51 mm.), but must 

 be referred to M. c. cinerea. 



Hab. I have examined specimens from the following 

 localities: — Gold Coast, southwards through Cameroon to 

 N'Dalla Tando, northern Angola ; eastwards to the Welle 

 River, Upper Congo, and Uganda (Entebbe and Mpumu). 



The two forms seem to meet in central Angohi. 



Another form closely allied to M, c. cinerea, if not iden- 

 tical with it, is Muscicapa modesta Hartlaub [Orn. W. Afr. 

 p. 96 (1857) Gaboon]. 



The bird described as M. modesta by Sharpe [Cat. Birds 

 B. M. iv. p. 156 (1879)] from the " River Danger, Gaboon. 

 Henry Ansell, Esq. [P.]/' is unquestionably an example, in 

 poor condition, of Fraseria cinerascens Hartlaub [c/. Sharpe, 

 Cat. Birds B. M. iii. p. 304. (1877)]. Part of the plumage 

 of this spetdmen is missing, but all the characters essential 

 for certain identification are still present. 



Dr. Reicheuow [Vog. Afr. ii. p. 453 (1903)] copied 

 Sharpe's description of his supposed M. modesta, but noted 

 that it differed from the original description given by 

 Hartlaub in important points. 



Sharpe subsequently identified a specimen of Alseonax 

 tessmanni Reicheuow with this species. 



Muscicapa lugens (Hartlaub). 



Butulis lucjens Hartlaub, P. Z. S. 18G0, p. 110 [Bembe,
