The black and went Dob- 
THE length from the bill to the rump is eleven | 
inches; the extent of wings twenty. ‘The bill 
is little more than an inch long; the crown of 
the head, and whole upper side of the body 
are dusky; the inner coverts, the ridge of the 
wing, and the middle quil feathers white ; the rest 
of the wing dusky; a bare skin of a fine red 
color joins the bill to the eye; the whole under- 
side from the breast to the rump is a silvery 
white ; on the thighs are a few black spots. In 
some the whole neck is ash-colored; probably 
they might have been young birds, or different 
in sex. Inhabits the fens of Lincolnshire.
