CIXNAMOPTERYX IN I ERSCAPULARIS 861 



latter, which Dr. Reichenow informs us is an immature bird of 

 the present species, came from Kingawanga (Stuhlmann), some 

 fifty miles north of the Albert Edward Nyanza, in about 

 0° 30' N. lat. by 29° 30' E. long. 



It is evident that in this species the sexes are similar 

 in plumage, and it is almost as certain that the adults are not 

 subject to any marked seasonal change of plumage, which is 

 also the case with llijphnnUirnis cucuUatus, for I have known of 

 two male cage-birds of that species which have retained the 

 bright coloured plumage during at least eight years, and one of 

 them I have still alive. 



Cinnamopteryx interscapularis. 



Ploceus interscapularis, Eeichen. Orn. Monatsb. 1893, p. 29 Bundcko ; 



id. Yog. Afr. iii. p. 53 (190i). 

 Malimbus interscapularis, Shelley, B. Afr. I. No. 490 (1896). 



Type. " Black, with the interscapular region yellow. Bill black ; feet 

 horny brown ; iris pale rufous. Total length 5'6 inches, culmen 0-76, 

 wing 3-24, tail 2-0, tarsus 0-76" (Keichenow). 



The Yellow-mantled Black-Weaver inhabits Central Africa. 



The type was discovered at Bundeko in about 1° N. lat. 

 29°50'E. long. 



This species is, I believe, known only by the type specimen, 

 and it appears to me possible that it may be a black-breasted 

 variety of G. tricolor, for the same collection contained an 

 immature specimen of the latter species (the type of Ploceus 

 ru/oniger) obtained at Kingawana, about half-way between 

 Bundeko and the Albert Edward Nyanza. 



Genus XIII. MELANOPTEBYX. 



Similar to Malimbus in structure, but is characterised by being black 

 with no bright colours. The plumage of the sexes is alike excepting in the 

 type species, in which the female is pale olive.
