Brewster on an apparently New Gull. 
[October 
we can at present only speculate, although there are some reasons 
for believing that it was the same with the bird which Kumlien 
found at Cumberland Sound. But in view of the uncertainty 
connected with this point it seems better to re-name the bird, 
which I do as follows : 
Lams kumlieni sp. hov. Lesser Glaucous-winged Gull. 
f Laroides ckalcopterus, Bruch, J. f. Orn., 1855, p. 22 (nec Licht.). 
f Larus chalcopterus, Lawr., B. N. A., 1858, p. 843; Coues, Proc. 
Philad. Acad., 1862, p, 295. 
Larus glaucescens , Kumlien, Contrib. to Nat. Hist. Arc. Am., pp. 98, 
99; Brewster, Bull. N. O. C., Vol. VIII, No. 2, p. 125; Merrill, loc. 
cit. 
Ch. sp. — Similis L. glaucescenti, sed minor ; inagis Candidas; pennis 
candidioribus ; colore atro in remigibus angustiore ac magis distincto a 
partibus candidioribus. 
$ , adult , breeding plumage (No. 76,225, Coll. Nat. Mus., Cumberland 
Sound, Arctic America, June 14, 1878. L. Kumlien). Bill short, stout, 
and comparatively straight, the convexity of the upper mandible slight 
and the angle of the lower mandible not strongly marked. First primary* 
longest. Tarsus about equal to middle toe and claw. Head, neck, tail, 
and entire under parts snowj-white ; mantle pale pearl-blue, much lighter 
than in argentatus and glaucescens , about as in leucopterus. Primaries 
* I am indebted to Mr. Ridgway for the drawing from which the accompanying 
illustration was made.
