[Cabanis's Black Titmouse was met with throughout the acacia-country on the 

 plains around the south end of Ruwenzori. It was, comparatively speaking, a rare 

 species on the east side of the range, but on the west, in the Semliki Valley, it was 

 one of the commonest birds. — R. B. JF.]

Adult male and female. Iris brown or dark brown; bill black; feet blue-grey or 

 slate-grey (in one example, olive-green). 



A fine series of this Titmouse was collected on Ruwenzori. The species is apparently 

 peculiar to the range. On the loth of January Mr. Carruthers procured a male 

 (No. 1146), which he has marked "breeding." 



A quite young bird (No. 198) differs from the adult in having the feathers of the 

 occiput and nape brownish edged with black (instead of uniform black) ; the chin and 

 middle of the throat black ; the cheeks, sides of the head and throat, as well as the 

 chest, greyish-brown (in the adult all these parts are black). The rest of the under- 

 parts whitish-bufi", inclining to tawny on the flanks (instead of white) ; the black stripe 

 down the middle of the breast indicated by a few blackish feathers ; the light margins 

 of the quills and wing-coverts yellowish- white (instead of pure white). The outer pair 

 of tail-feathers are much shorter than the middle pair ; whereas in the adult they are 

 of nearly the same length. 



[The Grey-backed White-breasted Tit was found on Ruwenzori from the forest-line at 

 about 6500 feet up to an elevation of 11,000 feet, where it frequented the tree-heaths. 

 It was, however, but rarely seen as high as this, and only when it had ascended the 

 valleys. It is really a bird of the forest-zone, where it is not uncommon. — R. B. W.}
