 the yellow shoulder-patch is much less extensive and is not continued over the 

 scapulars. Iris dark brown ; bill dusky; feet brown. Total length ca. 5-0 inches; 

 wing 2-55 ; tail 1-95 ; tarsus 0-82.

 k. I. s ^. 60 miles N. of Fort Beni, 3500 ft., 16th Aug. [Nos. 1787, 1788. D. C] 

 Adult male. Iris dark brown or dark hazel; bill light grey or bluish-white; feet 

 dark brown or black. 



Adult female. Iris dark brown or dark hazel ; bill brown or horn-colour; feet brown 

 or light brown. 



The adult males shot in July, August, and September are in full breeding-plumage. 

 Three of the adult birds collected on the 8th and 9th of December have nearly 

 assumed their winter dress, while the fourth is still in the black breeding-plumage. 



The two females (Nos. 1577 and 2402) have the lesser wing-coverts conspicuously 

 margined with dark orange, forming a well-marked patch on the shoulder ; No. 1788 

 has the lesser wing-coverts rather inconspicuously margined with yellowish. All three 

 birds appear to be perfectly adult, and No. 1577 is marked "breeding" by Mr. D. 

 Carruthers. The pale-shouldered specimen (No. 1788) was one of a pair (of which 

 the male, No. 1787, is in perfect breeding-plumage) and is in worn plumage. Possibly 

 the orange shoulder-patch is not assumed till after the second moult. 



[Heuglin's Fan-tailed Whydah was seen throughout the journey from Victoria Nyanza 

 to the Congo Forest, but was not met with on Ruwenzori above an altitude ot 

 5000 ft.— jS. B. W.]
