Prom D. a. nandensis. to wliicli it is most nearly allied, it 

 is distinguished by liaving the general colour of the upper- 

 parts (excepting the head) greyer, particularly on the 

 mantle, wings^and tail. The head and nape are darker blue, 

 and lack the grey wash of D. a. nandensis — moreover, 

 this colour extends further on to the mantle. The sides of 

 the body and flanks are strongly washed with French grey, 

 of a more intense colour than even in D. angoleiisis. This 

 cliaracter is practically absent in D, a. nandensis. In size 

 D. a. cameroonensis IS, decidedly smaller than D. a. nandensis, 

 the wing measuring 82 mm., as compared with 87-90 in 

 the East African form. Culmeu (exposed portion) 19 mm. ; 

 wing 82 ; tail 61 (from the base of the middle tail-feathers) ; 

 tarsus 21.

 Mountain, 11. v. 09. Boyd Alexander coll. 



Alexander also obtained a male and female on Cameroon 

 Mountain of a bird which has up till now been known from 

 the type only — a female in the British Museum Collection. 

 This is Nesocha7'is shelleyi Alexander, which was described 

 in the 'Bulletin of the British Ornithologists' Club,' xiii. 

 1903, p. 48 — Alexander having obtained it in Fernando Po. 

 This bird, which will be figured in the next ' Ibis/ is most 

 nearly allied to Nesocharis ansorgei, described from Toro 

 by Dr. Hartert, and figured in the Report of the Ruweuzori 

 Expedition. 



As the male is very diflferent from the female, I propose 

 to describe it as follows :^- 



Nesocharis shelleyi Alexander. 



Adult male. Entii-e head and upper part of the throat jet- 

 black ; a wide grey band on the nape dividing the black head 

 from the rest of the upperparts, which are golden-olive 

 becoming brighter on the rump. Upper tail-coverts, which 

 extend over two-thirds of the tail, golden-yellow ; tail black. 

 Primaries very dark brown margined on the outer web with 

 golden-olive ; under wing-coverts white. Lower part of the
