Nigerian-Cameroon Highlands, 3 October, 1921. G. L. Bates 

 coll. 



Ohs. I sent these specimens to Dr. Streseraann at the Berlin 

 Museum, and have since heard from Professor Neumann, 

 who examined them, that they differ from the type- 

 specimens of A. alJiiventris Reich, in being far darker on the 

 underside and especially yellow on the belly. They most 

 resemble, he says, A. murinus subsp. from Lendu, Central 

 Africa, and slightly A. m. si(htilis Grote {cf. Grote, 0. M. 

 1920, p. 114). 



" Of very particular interest are the Francolins, specimens 

 of which, belonging to the species F. hicalcaratus, Mr. Bates 

 collected in the Banso mountains, 6000 ft., near Jang 

 (or Chang), 5000 ft., and again in the lower ground at 

 Yoko. The Banso Mountains are now included in Nigeria ; 

 Jang is a little to the south, just over the Cameroon 

 boundary ; while Yoko is much further to the east out of 

 the mountain-chain, and lies at an altitude of under 2000 ft. 

 The Francolins from the mountains certainly belong to an 

 nn described form, and at the special request of Mr. Bates 

 I propose to name them 



Francolinus hicalcaratus ogilvie-granti, subsp. nov. 



($ ad. Differs from typical F. h. hicalcaratus and the form 

 found in the Gold Coast and Nigeria in having the upper 

 parts, including the crown, very much darker, resembling 

 in this respect F. h. tlwrnei from Sierra Leone and Liberia. 

 The underparts, however, are quite distinct from F. h. hical- 

 caratus and F. h. tlwrnei., iis, instead of having cream-coloured 

 or white margins, those feathers (right down to the base) 

 are deep isabelline-buff, as well as the streaks and drops 

 within the black breast-markings. 



From F. h. adamauce described from Garua some 600 

 kilometres further north, this new form may be distinguished 

 by the heavy chestnut markings on the under surface and by 

 having the usual breast-markings of the hicalcaratus group, 

 which, according to Neumann, are absent in F. h. adamame.
