GLAUCOUS GULL. 563 



borrowed his description from Latham : — " Ovum virescens, 

 ad apicem minorem elongatum, maculis 6-8 difFormibus 

 nigris." It is not worth while to trace it any farther. 

 Surely, in this matter, these people are mere compilers. 



Young. — The bill is horn-colour, or pale yellowish-grey ; 

 the upper mandible brownish-black beyond the nostrils ; the 

 lower beyond the angle. The feet are flesh-colour ; the claws 

 lightish-brown. The general colour of the plumage is pale 

 yellowish-grey, with a tinge of brown ; the head and neck 

 marked with longitudinal streaks of very pale greyish-brown ; 

 the upper surface in general marked with transverse irregular 

 bars of pale-brown, becoming larger and of a deeper tint on 

 the hind parts, each feather being whitish-grey at the base, 

 and in the rest of its extent with several alternate bars of 

 pale-brown and whitish-grey, tinged with yellow, the tip 

 yellow. On the tail the bars are partially substituted by 

 irregular spots. The lower surface is confusedly mottled 

 with very pale-brown, tinged with ash-grey and yellowish- 

 white ; the lower wing-coverts are very pale-grey, mottled 

 with very pale brownish-grey. The primary quills are gi'ey-

 the outer webs ; the secondaries distinctly mottled on both 

 webs, and toward the end irregularly banded, the inner like 

 the back.

 end ; the primaries are also pale ash-grey, white toward the
