markings on the tertiaries, primary coverts, and bastard 
wing', with an imperfect sub-terminal bar on the tail, 
point it out as a young bird, most probably commencing 
its second spring. The rest of its plumage corresponds 
with that of L. zonorhynchus, except that it wants the 
extreme white tips of the quill feathers, which, on the 
third and following ones, are very conspicuous in L 
zonorhynchus. It differs, however, remarkably in its 
bill being shorter, though considerably stouter than 
that of our L. cams; and, like it, it is wax yellow, 
with a bright yellow rictus and point. Its tarsus is 
nearly one third shorter than that of L. zonorhynchus. 
Many may be disposed to consider this as merely a 
local variety of L. cams; and it might be urged, in 
support of this opinion, that there are considerable 
differences in the length and thickness ol the bills of 
individuals of the common and winter gulls killed on 
the English coasts, which are all usually referred to 
L. canus. We have judged it advisable, however, to 
call the attention of ornithologists to these American 
birds, by giving them specific names, leaving it to future 
observation to determine whether they ought to retain 
the rank of species, or be considered as mere varieties.
