DlAPHOROPHYIA TONSA, sp. n. 



Adult female. Forehead and crown glossy black; lores and 

 ear-coverts greyish ; superciliary stripe white ; back, wing- 

 coverts, and the edges of the innermost secondaries light 

 chestnut ; outer edges of the remaining quills pale rufous- 

 white ; feathers of the rump grey tipped with white ; tail- 

 feathers black, with very narrow white margins. Chin white ; 

 throat and chest chestnut ; rest of the underparts pure 

 white ; under wing-coverts and axillaries white ; marginal 

 under wing-coverts grey edged with white. Eye-wattle 

 short and narrow, not reaching to the hinder angle of the 

 eye, or hiding the white superciliary feathers as it does in 

 D. castanea, Fraser. Feathers of the crown remarkably 

 short; in D. castanea they form something of a crest. Culmen 

 12 mm.; wing 55 ; tail 25. 



Hab. South Cameroon. 



Type in the British Museum. ? ad. No. 4039 (with ova 

 and oviduct somewhat enlarged). Bitye, River Ja, xi. 09. 



An immature female (No. 3275 ; Assobam, River Bumba, 

 Dec. 1908) is also doubtless of this species. It has a grey 

 head like that of D. castanea, but the same light chestnut 

 colour of the back and the same peculiarities of the eye- 

 wattle and feathers of the crown as in the adult bird just 

 described. Culmen 11 mm. ; length of wing 55. 



An adult male (No. 2970; collected at Bitye, March 1908) 

 is coloured as in the male of I), castanea ; it has the pecu- 

 liarities of the eye-wattle and the short crown-feathers of 

 JJ. tonsa, and may be the male of that species.
