minatis : subtus castaneum, maculis infreqiientibus nigris. 



Long. tot. 8-6, alse 4-25, caudae 4<, tarsi 0-9. 

 This is a distinct species^ but unfortunately the collection 

 does not contain a male. It belongs to the same group as 

 E. schisticeps. 



18. Graucalus sublineatuSj Scl. P. Z. S. 1879, p. 448, 

 pi. xxxvi. 



The iris is light yellow and the feet black. 



19. Graucalus, sp. inc. $ . 



I believe the specimen sent, shot at the same time and place 

 as the preceding, and with a light yellow iris, will prove to be 

 the female of the above species (G. sublineatus) . It coincides 

 exactly in all its measurements, but instead of having the under 

 surface schistaceous, with faint narrow white wavy trans- 

 verse markings, the whole of the breast, abdomen, flanks, 

 and under tail-coverts are white, with black transverse bais, 

 equal in width to the white spaces. 



20. Graucalus monotonus, sp. nov. 



G. supr^ et subtus caeruleo-cinereus ; loris, remigibus pri- 

 mariis et secundariis nigris, his ad marginem cinereo 

 iavatis ; rectricibus mediis nigris cinereo adumbratis, la- 

 teralibus cinereo terminatis ; rostro et pedibus nigris. 

 Long. tot. 9' 75, alae 4*75, caudse 4"3, tarsi 1, rostri a 

 rictu 1"25. 

 This bird, Avhich Mr. Sharpe has not been able to identify 

 with any species known to him, in coloration most nearly 

 resembles G. casius (Licht.) from South Africa, but is darker 

 in colour, with a much longer and stronger bill and black 

 lores j and the wings and tail are jet-black, instead of brown- 

 black. 



21. Pachycephalus christophori, sp. nov. 



P. ^ supra omnino olivaceus ; rectricibus et remigibus fuscis, 



in pogonio externo olivaceo marginatis ; meuto et thorace 



flavis, torque nigro ; abdomine, crisso et subalaribus flavis. 



$ mari similis, torque absente. Long. tot. 5 "9, alai 3'3, 



caudse 2'5, tarsi 1. 



The iris brown, the feet ash-coloured. The young male is 



like the female, but with faint traces of the black collar.
