p. n. insignis has the lesser upper wiug-coverts partially black like leucomelas, 

 but the outer edges of the lateral rectrices are narrowly white. 



139. Heliolais erythroptera erythroptera (Jard.) 



Drymoim e.rythrnplem Jardine, Contr. Oni. 1849, p. U'l (W, Africa). 



S ad., Zaria, 12. ix. 1912. 



Wing 53 mm. • 



140. Prinia mystacea subsp. ? 



1 ad. Kano, c? ad. Zaria, 13. ix. 1012. 



There appear to be some separable subspecies of P. mystacea, but I cannot, 

 at this moment, attempt to elucidate them.

 c? ad., Zaria, August. 



142. Thamnolaea coronata Rchw. 



Thamiiolaea coronata Reichenow, Orii. ilomtsher. 190:i, p. 157 ; Viig. A/i: iii. p. 703, Alias, pi. x.wi. 



fig. 2 (Tapong in Togolaad). 

 Thamnolaea claudi Alexander, Bull. B. 0. Club, xvi. p. l-'4 (1900— Pettia). 



One fine adult male, province of Zaria, no date I 



Some of the feathers of the crown of this freshly moulted bird have blackish 

 tips, which would soon wear off. The wings measure 110 5 mm. 



I am not aware that anything is known of this rare species, except the type 

 in the Berlin Museum, from the interior of Togoland, aud the specimens collected 

 by Boyd Alexander in Nigeria. " T. claudi " is the female, which has the crown 

 slate-grey, not white. 



143. Cossypha albicapilla giffardi Hart. 

 Cossypha giffardi Hartert, Bull. B. 0. Club x. p. .'') (Gambaga, collected by Capt. Giffard). 



One adult bird from Kaduna, on the Kadnna River, province of Zaria, 1912. 



Cossypha albicapilla omoeitsis Sharpe {Bull. P.O. Club xi. p. 28, 1900) is 

 closely allied to C. a. giffardi, but the back is darker blackish, the underside darker 

 rufous. The dusky markings on the outer tail-feathers, however, though somewhat 

 variable, are the same in both subspecies. The wings of C. a. omoensis are shorter. 

 Wings in C. a. giffardi : 137, 134, 126, 123-5; in C. a. omoensis: 119, 125, 116, 

 123, 126'5mm.; the males much larger than the females, but some specimens 

 apparently incorrectly sexed. 



144. Saxicola rubetra (L.) 



?, Zaria, 22. X. 1912. 



(? freshly moulted, without date, province of Zaria. 



The male is very pale and wonld appear to be S. ntbetra spatzi (Erl.), while 

 the female is darker and might pass as a S. r. rubetra ; but these forms 

 require further investigation.
