a,b. S • Kaka, 25th Feb. & 8th March. Nos. 71 & 116. 



Iris black, with narrow scarlet border ; bill black ; legs 

 and feet bright pink. 



These males of the Black-winded Stilt, with the hinder 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'cous.

a. ? . Fd-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.

Limosa limosa (Linn.); Grant & Reid, p. 691. 

 Limosa belgica (Gmel.); Witherby, p. 277.

c. ? . Ed-Duem, 23rd May. No. 567. 



Irishcizel; bill flesh-coloured, dusky or blackish at the tip; 

 legs and feet black. 



Though these three Black-tailed Godwits are all marked 

 as females, I 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. 



181. TOTANUS CALIDRIS. 



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