iho groy tints of tlio neck passing forwards and downwards in 
front of tho pinions, when closed (as shown in Gould’s plate), cover 
a more extended space, are darker and more distinctly barred, but 
in both the throat, breast in front and under parts, generally, are of 
a spotless white. 
Ihe feathers on tho back and wing-coverts have the terminal 
margins much brighter, and tho mottled appearance is therefore 
more striking. 
Ihe outer webs of tho primaries are a more pronounced black; 
ami tho sixth primary, as shown in the woodcut, has an oblong 
white patch on tho outer web besides the white tip ; the white of 
tho inner web jiassing round tho tip of the feather, where it joins on 
to a black spot having this oblong white patch just above it. I 
could find no trace of this peculiarity in tho corresponding feather 
ol my own specimen until submitted to a very powerful light, 
when it was just possible to detect a lighter tinge on tho web in 
the spot where tho white patch would come, but no one could 
detect this without purposely looking for it. 
Sixth primabt in the male from Yarmouth. 
1 lie tail-feathers have the black on tho anterior portion, like tho 
primaries, of a richer hue, and the white marginal lines are much 
more vivid. 
The description given by ^Ir. Harting * of the Thames 
specimen agrees very closely with my own, and though the sex was 
not ascertained, it was probably, I should say, a female. Like 
mine also, it had no “ white spot of an oval shape” on the outer 
web of the sixth primary.
