PARUS PALLIDIVENTRIS. 239 



The most northern known range for the species is Leopolds- 

 ville on the Congo, from whence it extends southward into 

 Benguela, where Anchieta discovered the type at Caconda and 

 informs us that it is called by the natives " Caxito," also 

 apparently " Quitiaguenene," as that name is the one inscribed 

 on the label of the specimen figured in Bocage's Orn. Angola, 

 which was presented to me after Mr. Keulemans had finished 

 his sketch. 



The pale race for which I propose the name of P. 

 masukuensis is possibly very local, as it is known only from 

 the Masuku mountains of North Nyasaland in about 10° S. lat. 

 It is represented in the British Museum by specimens labelled, 

 Nyika plateau, June, and Masuku range, July ; the latter 

 I make the type, as it is in very good condition. These two 

 specimens agree perfectly in colouring and measurements, and 

 are so nearly intermediate between typical P. rufiventris and 

 P. pallidiventris that I formerly referred them to the latter 

 species ; but in looking more closely into the matter I con- 

 sider they represent rather a pale race of P. rufiventris than 

 a dark form of P. pallidiventris.

Adult. Similar in size and very nearly so in colouring to P. masukuensis, 

 but differs in the paler rufous buff of the breast, and is intermediate in
