tunately a sufficiently large series was not collected, but I 

 have no doubt that tiie ej;gs of this species vary to the same 

 extent as do tbose of other Weavers. The eggs taken 

 cannot be distinguished from similarly coloured eggs of 

 P. dimidiatus. At Jinja, these birds were breeding in 

 January. 



Localities. Kampala, Buziranjuvo, and Jinja, in Uganda. 



Ploceus (Sitagra) dimidiatus.

Nestlings 5. 



Tlie males in this series, from the north shore of Lake 

 Victoria, westward' to the lakes, are all dark birds. They 

 have the black of the head extending well over the nape 

 behind, and on to the crop below in the form of a triangular 

 patch. The mantle is dark olive-yellow with dark shaft- 

 streaks to the feathers, giving to it a streaky appearance. 

 The colour of the mantle is separated from the black of the 

 nape by a very narrow yellow band. The rump is light 

 olive-yellow ; the underside is very dark chestnut, not 

 quite as dark as in P.jacksoni,

This series, comprising birds in good plumage, collected 

 from one nesting-colony in one day, are all alike. They 

 present the following characters : — The black of the head 

 does not extend much beyond the posterior angle of 

 the eyes, is tinged with rufous at the edges, and does not 

 extend far on to the crop ; there is a wide light yellow band 

 separating the black of the head from the golden-olive of 

 the mantle ; the rump is bright yellow ; the breast and rest 

 of the underparts are cadmium-yellow with only a small 

 amount of rufous or chestnut shading on the crop ; in 

 two specimens this shading is almost absent, thus closely
