BIRDS OF ETHIOPIA AND KENYA COLONY 



151 



typical race has the crown dull black, while in saturatior it is glossy 

 black. 



3. C. 8. donaldsoni: The Harrar area and eastern Gallaland. This 

 form has the upper back slaty bluish gray. 



4. C. s. intercedens : The highlands of south-central Kenya Col- 

 ony — Ukamba and Kikuyu to Mount Kenya and the Aberdare Moun- 

 tains. This form is similar to donaldsoni but has a slightly longer 

 wing according to Sclater. The specimens seen by me have wings 

 of 90 to 94 mm. I have seen no donaldsoni material. 



It is not generally known that this bird occurs on Mount Kili- 

 manjaro, but I have seen one undoubted example from there (U. S. 

 N. M. no. 118104, adult male collected by W. L. Abbott at 5,000 feet 

 on Mount Kilimanjaro). This bird was listed by Oberholser ^"^ as 

 Cossypha heuglin^ inteivnedia. It is the smallest example of inter- 

 cedens seen by me (wing 86 mm) and may be donaldsoni^ or else an 

 undescribed race, but more material is needed to decide the point. 



The measurements of the present series are shown in table 31. 



There is some variation in the width of the white superciliary 

 stripes. In one male tliese stripes are connected across the forehead, 

 while in the rest of the series there is no such frontal connection. The 

 birds are all in fairly fresh plumage.

Neumann " found this bird to occur at altitudes of from 2,500 

 to 3,100 meters. Pease ®^ met with it frequently in dense bushy 

 thickets and under "creeper-covered earth-banks." 



Erlanger ^^ found the east Ethiopian form donaldsoni nesting dur- 

 ing May in the region west of Harrar. He considers this form as a 

 race of subrufescens while Sclater, in turn, classes it as a form of 

 heuglini. 



Besides the specimens procured, Mearns saw this bird at the fol- 

 lowing places: Abaya Lakes, March 21-26, 4 birds; between the
