Agrees with a Natal specimen in the Bremen Museum. The white gular patch is 
more defined in the middle of the chin and throat, becoming on the latter broader. 
The white feathers on the rump have a narrow dark central line, more visible in 
the South-African specimen. In another specimen from Abyssinia, in the Bremen 
Museum, these dark central lines on the feathers of the rump are scarcely visible, and 
the white on the chin and throat is very extended, reaching on each side to the cheeks ; 
this specimen shows also a light supraocular stripe. I was inclined to take these 
differences as being of specific value; but having seen southern specimens in which 
the white on the throat is extended as widely, I can only see therein individual variety, 
and this especially as there are intermediate forms. A specimen from Dembea, in 
Von Heuglin’s collection, exhibits not the slightest difference from our Natal specimen. 
Dr. v. Heuglin, who compared it with southern ones in the Stuttgart Museum, believed 
it might be a new species, and named it previously C. gularis. It may therefore be 
considered, as a rule, that the Cypseli vary considerably in the peculiarities mentioned 
above.

Easily distinguished from the foregoing species by the tail being nearly straight; 
otherwise quite the same.
