Brewster 071 a?i 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 : 



Larus kumlieni sp. nov. Lesser Glaucous-winged Gull. 



^ Laroides ckalcopiei'us, Bruch, J. f. Orn., 1855, p. 22 (nee Licht.). 



P Larus ckalcopterus, 'L.KWS.., 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 Z.. ^/«?<ce5ce«^'/, sed minor ; inagis candidus ; 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 snowy-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.
