we take to be adults. About half of these have pure white 

 backs, and mainly come from the northern part of tne 

 country; the remainder have chestnut, or chestnut raixfed 

 with deep blue, backs, and mainly come from the southern 

 portion. These latter have a large amount of black in the 

 tail, generally all the feathers except the long central ones 

 being black ; but we take this to be a western characteristic, 

 and in no way connected with age. Two birds also from 

 Sennar have short red and white tails, and backs chestnut 

 sprinkled with white. They are probably almost typical 

 T. V. ferreti, which appears to adopt a white plumage direct 

 from the red short-tailed dress of the first year.

On examining the material in the British Museum, we 

 came to the following conclusions as regards the races : — 



1. Elminia longicauda longicauda Swains. Underside 

 darker, more bluish. 



Range. Senegal to North Nigeria. 



2. Elminia l. teresita Ant. Underside paler, white on 

 the belly. 



Range. Bahr el Ghazal to Cameroon and Uganda; also 

 to Mount Elgon. 



3. Elminia l. schwabischi Oustalet, N. Arch. Mus. 

 Paris (3) iv. 1892, p. 216 : Franceville, interior of Gaboon. 



Of this bird we know nothing beyond the description, 

 which does not appear to distinguish it from E. I. teresita. 



4. Elminia l. loand^, subsp. nov. 



There are in the Museum five very brightly coloured 

 examples of this group which appear to be quite distinct, and 

 we propose to name them as above.
