Dendrocygna fulva (Gmelin). 



(^ juv. Vm Ruaba, Kordot'an, Dec. 1920. 



Fuligula fuligula (Linnseus). 



cJ ? . Singa, Jan. 1921. 



The male lias the iinderparts and parts of the tail stained 

 a deep riisty chestnut. I have never seen a duck stained to 

 such an extent. The new feathers which are appearing in 

 the tail and on the abdomen are normally coloured. 



Fuligula brunnea (Eyton). 



A live bird from Um Ruaba, Kordofan, obtained Dec. 

 1920. 



This example, Flower tells me, was quite a young bird ; he 

 saw it in the yard of an Arab's house with young specimens 

 of Dendrocygna. The owner, who did not distinguish this 

 bird as different from his other young ducks, stated that he 

 had obtained them all from the Um Ruaba " fulah/' where 

 many waterfowl breed. 



This seems to be a very great northern extension of the 

 range of this duck. 



1 use Eyton's name for this species as, owing to lack of 

 literature, I do not know if Neuwied's name erythroplithahna 

 is applicable as stated by Sharpe, ' Hand-list of Birds,' vol. i. 

 p. 223. 



Himantopus himantopus (Linna3us).

Charadrius alexandrinus alexandrinus (Linnseus). 



? . Sennar, Jan. 1921. 



This example has a wing of 111 mm., and is undoubtedly 

 of the typical form. Specimens from Egypt vary in wing 

 measurement : out of a large series, eight in the Giza 

 Museum are from 100 to 104 mm., but one of these was 

 breeding with long-winged birds. 



Charadrius duhius curonicus Gmelin.

Two of these are gettino- the black collar and frontal band 

 of summer plumage. It seems to be little understood that
