marking they remind us of the summer appearance 
of some of the Charadriadm or plovers. 
Specimens, in the summer dress, procured on the 
margins of some of the lochs in Sutherlandshire, 
present some difference, both in size and tint. They 
run, in total length, from six to six and a-half inches, 
the parts keeping a near proportion one to another. 
The whole upper plumage shows a much greater 
mixture of black, the rufous edges of the feathers 
being narrower, their colour deeper, and with less

marking on the throat and breast occupies a much 
greater part of the feather, and is more angular in 
form, and the hlack patch on the belly proportion-

the flanks. It might be curious to ascertain if this 
state prevailed among northern birds, and if there 
is much difference in their size.
