218 ON BIRDS FROM THE CONGO 



pure Avhite , and the third and fourth show fully developed 

 cross-bars. Another has only the three first primaries bar- 

 red with white , and still another (9) has five quills — in- 

 cluding the first — extremely broadly barred with rufous , 

 so that I first held it for C. fossii.

 ■ Caprimulgus fervidus , Sharpe, Birds S. Afr. p. 86. 



An adult female (N° 288) from the Kasinga River, 

 30 March. 



This fine species can easily be distinguished from C. ru- 

 Jigena by its somewhat larger size , the extremely broad 

 golden brown collar round the neck, ditto lores, cheeks 

 and chin. The latter , however , is nearly black in two other 

 specimens we have in our collection. Moreover the narrow 

 terminal part of the second , third and fourth quill is 

 longer than in rufigena , and reaches up to about halfway 

 on the white or rusty-red cross-bars , while in rujigena 

 this narrow part does not reach as high as the latter. As 

 to this character C. fervidus agrees with the much darker 

 C. pectoralis , this latter , however , has the rusty collar not 

 as broad and the terminal part of the two outermost pairs 

 of tail-feathers white to a greater extent. 



Iris dark brown, bill and feet horny.
