holds good for the birds from Kerna, and Meru borna as well. Therefore I tliink that 

 Jackson's name of 1910 must be put as synonymous with Dearborn's of 1909. It ap- 

 pears also the best proceeding to regard A. carrulhersi as a geographic subspeeies of A. 

 poliocephala. 



Cossypha caffra iolaema Rchw. 



Rchw. 1H. ]i. 754. 



The first specimen of this bird was secured near Escarpment station in a thick growtlt 

 of tall herbs and bush through which it slipped with great agility, and sometimes raised 

 the tail in the air. Låter I had the opportunity of obtaining specimens at Fort Hall in 

 bush, and at Punda Melia in a thicket of papyrus. 



All my specimens are similar inter se but somewhat darker than a specimen from 

 Kilimanjaro, and have especially less white on the lower side than the latter. 



Cossypha subrufescens Boc.

In the forest near Meru borna and in the forest two hours north of the borna speci- 

 mens of this bird were secured. They are similar to specimens from Kilimanjaro, although 

 not quite so much washed with olive on the back as the latter. The middle tail feathers are 

 black, but the outer tail feathers have the greater part of the outer web blackish brown 

 in one specimen, and in the other there is a black margin över more than a third. In con- 

 sequence of this they cannot be counted to the subspeeies C. s. donaldsoni Sharpe to which 

 they, however, approach in some degree. This is especially the case with the specimen 

 from the forest north of Meru borna, the one with less blackish on the outer tail feather, 

 because it is decidedly smaller in size. Its length of wing is only 84 mm., and the length 

 of the tail is 74 mm. The corresponding figures for the other specimen are 99 and 92 

 mm. This difference is undoubtedly great, although its importance is lessened by the dif - 

 ference in sex, the smaller being a female. 



Erythropygia leucoptera (Rfjpp.).

In the thornbush north of Guaso Nyiri. Specimens were secured in several places, 

 at Njoro, and nearer the river as well above as below Chanler Falls. The specimens seen 

 kept usually near the ground flying from bush to bush. 



It appears to be member of the north-eastern fauna. 



Erythropygia hartlaubi Rchw. 



Rchw. III. p. 775. 



One specimen of this species was obtained in bush at the edge of the forest reserve 

 at the Limuru road not far from Nairobi.
