94 audouin's gull. 



transverse black bands near the tip of both mandibles; 

 the naked circle round the eyes golden; the legs, 

 toes, and webs black. 



In their summer dress they have the head, nape, 

 and neck white, these parts, as well as the crop, 

 lightly shaded with rose. Beak blood red, always 

 carrymg, in a manner more or less decided, two 

 black transverse bands. 



The young of the year have generally a plumage 

 more or less tinged with many shades of ash and 

 brown; the mantle . brown, irregularly spotted with 

 clear brown and russet; and the tail more or less 

 spotted with black and brown. In their second moult 

 in autumn they assume some grey traces on the head 

 and neck; but after their second moult in spring the 

 plumage is perfect. 



My figure of this bird is taken, in the absence of 

 an authentic skin, from that of Mr. Gould. The egg 

 from Thienemann. 



The bird has been figured by Temminck and Laugier, 

 pi. col. 480, adult in spring plumage; Gould, B. of E., 

 pi. 438.
