It would seem, however, that the young of this species differ not 
a little, inter se, independent of any sexual differences, as the first 
Irish specimen (Belfast Bay, September, 1822), recorded and 
described by Thompson, exhibited the following features, not 
observable in either, or in one only, of the Norfolk birds, and not 
in that killed on the Thames. The sex does not seem to have been 
ascertained, 
(1) A narrow line of greyish hlaclc closely encircling the front 
and lower part of the eye.” “ Space immediately above the eye ” 
white, as in one only of the Yarmouth birds. 
(2) Back, wing-coverts, etc., “ blackish grey, tinged with 
yelloioisli hrown.” On the outer web of the sixth primary 
“a white spot of an oval shape appears,” as in Mr. Connop’s 
Yarmouth bird. 
(3) “ Under part of throat and upper part of the breast pale 
ash colour'’ In both Norfolk birds the under part of the throat, 
and passing downwards to the vent, hetween the grey patches that 
front the carpal joint on either side Avhen the wing is closed, is a 
pure unbroken white. 
The measurements of the two Norfolk birds are as follows, those 
of the female taken in the flesh, and the other when stuffed : —

The hind toe and claw are exceedingly small, and Thompson 
points out that it is “ placed so high that the point of the nail 
does not reach within one and a half line of the ground.” Tail- 
feathers twelve; the irides and bill in my bird were dark brown, the 
legs and feet a soiled flesh-colour.
