IrivS black, with narrow scarlet border; bill black; legs 
and feet bright pink. 
These males of the Black-winged Stilt, with the binder part 
of the crown, feathers surrounding the eye, and ear-coverts 
blackish grey, are apparently fully adult birds in winter 
plumage.

A nearly adult Avocet has the iris hazel, the bill black, 
the legs bluish grey, and the feet ochi'eous. 
179. NUMENIUS ARQUATA. 
Numenius arquata (Linn.); Sharpe, Cat. B. Brit. Mus.

a. ? . Ed-Duem, 21st May. No. 534. 
Iris hazel ; bill black, lighter at the base of the lower 
mandible ; legs and feet slaty blue. 
This female Curlew has an abnormally long bill, measuring 
6*8 inches. 
180. LiMOSA LIMOSA. 
Limosa limosa (Linn.); Grant & Reid, p. 691. 
Limosa belgica (Grmel.); Witherby, p. 277. 
a. $ . Khartum, 26th Jan. No. 23. 
b. ? . Fashoda, 31st March. No. 268. 
c. ? . Ed-Duem, 23rd May. No. 567. 
Iris hazel ; bill flesh-coloured, dusky or blackish at the tip ; 
legs and feet black. 
Though these three Black-tailed Godwits are all marked 
as females, 1 am inclined to think that specimens b and c may 
have been wrongly determined. In both of these the bill mea- 
sures about 3*8 inches, while in specimen a it measures 4*7.

Totanus calidris (Linn.) ; Witherby, p. 277 ; Grant &
