 Zanzibar Province to Dar-es-Salaara. 



Colius leucotis, which is the north-eastern representative 

 of C. striatus, presents, like that species, two if not three sub- 

 specific phases, Avhich may enable the practised eyeto recognize 

 the districts from which they come, 



a. Larger : wing 3-8 to 4. Tail-feathers generally slightly broader. 



Neck and back generally more distinctly barred. 



1. C. leucotis ti/picus. N.E. Africa, extending 



southward to Kitui in Ukamba. 



b. Smaller : wing 3'85 to 3*76. Tail-feathers generally slightly 



narrower. Neck and back generally less distinctly barred. 



2. C. leucotis affinis. E. Africa ; Upper 



White Nile to Dar-es-Salaam. 



The small race h shows the strongest variation in two 

 specimens from Dar-es-Salaam ; in these the back is entirely 

 without signs of bars, the upper parts are slightly more 

 rufous, and the white on tlie throat and sides of the head 

 clearer and more strongly contrasted with the surrounding 

 brown of the plumage. 



These subspecies appear to run into each other. 



8. Colius leucocephalus.
