We have followed Neumann in his recent monograph of 

 this group and have retained the name nilotica, though the 

 type species C. a. ansorgei is from Angola and only known 

 from one example. 



The fine series collected by Lynes and Lowe exactly match 

 the specimen collected by Emiii at Wadelai. 



The young birds, one from Mongalla and one from 

 Lake No, are ochraceous rather than ashy, especially below. 



The colour of the soft parts is as follows : Iris sieuna ; 

 upper mandible smoky brown, lower yellowish brown ; 

 legs sepia, sometimes with a greenish tinge ; mouth-lining 

 pale yellow. 



Measurements of the wings of five males, 72-78 mm. ; 

 of four females, 74-76 mm.
