Adult male and female. Iris dark hazel or dark brown; bill dusky, bluish-grey, or 

 black; feet grey, dark grey, or dark blue. 



The above-mentioned series collected at Mokia is apparently similar to specimens 

 from Entebbe which have been described by Count Salvadori under the name A. roccatii. 



This is quite a distinct species, but perhaps most nearly allied to A. punctifrons 

 (Sundev.) from North-east Africa and to A. capensis (Gmel.) from S. Africa. 



It has the colour of the upperparts of a dark olive-green ; in A. punctifrons they 

 are yellowish-olive and in A. capensis brownish-olive: the underparts are pale 

 yellowish-white, intermediate in colour between the almost white-breasted A. puncti- 

 frons and the yellow-breasted A. capensis. From both these species it may be easily 

 distinguished by having the fore part of the forehead yellow, with no trace of black 

 tips to the feathers, and though some of these are more or less indistinctly tipped with 

 greyish, the forehead has a uniform yellow appearance. 



[A very few examples of Roccati's Penduline Titmouse were seen among the acacia- 

 trees on the plains around the south end of Ruwenzori. — B. B. W.]

Adult male and female. Iris dark brown (in one specimen olive-brown) ; bill black, 

 grey at the base of the lower mandible ; feet bluish, bluish-black, or dark grey. 



I have referred the above-mentioned specimens with some doubt to N. camerunensis 

 Neum., which was founded on a single female specimen from South Cameroon. The 

 females from Ruwenzori agree fairly well with the description of that bird, and there 

 is no reason geographically why they should not belong to the same species ; but before 

 this point can be definitely settled it will be necessary to compare adult male specimens 

 from the two localities. The males from S.E. Ruwenzori, on the whole, most nearly 

 resemble N. minor Sharpe, and, as in that species, the markings on the sides form a
