296 Allen, Kumlicn's Gull near Boston. [jilly 



The following shows nieasuremeuts of eggs: 



A set of five rather long eggs: 2.59 X 1.79, 2.69 X 158, 2.73 X 179, 

 2.60 X 1.80, 2.57 X 1.79. 



A set of five rather roimd eggs:— 2.56 X 1.93, 2.58 X 1.86, 2.51 X 1.89, 

 2.48 X 1.91, 2.50 X 1.90. 



A set of three extremely large eggs: 2.76 X 1.94, 2.75 X 1.91, 2.74 X 

 192. 



A set of three extremely small eggs: 2.45 X 1.82, 2.51 X 1.80, 2.52 X 

 1.72. 



A set of six typical eggs: 2.57 X 1.83, 2.61 X 1.77, 2.55 X 1.78, 2.56 X 

 1.79, 2.57 X 1.81, 2.58 X 1.80, 2.574 X 1.816. 



The average size, taken from ten sets, — namely: three sets of three 

 each; four sets of fom* each; two sets of five each; one set of six, is 2.574 X 

 1.816 inches. 



I endeavored this year to ascertain the exact length of time required 

 for incubation; also from hatching to flight; but found it impossible, 

 owing to the distance and time consiuned in reaching their breeding ground. 



These notes have been culled from data taken by my father and myself. 



Trusting that this may be of some little benefit to you, I remain, 

 Your most sincere friend, 



A. O. Treganza. 



LARVS KUMLIEXI AND OTHER NORTHERN GULLS 

 LN THE NEIGHBORHOOD OF BOSTON. 



BY FRAXCIS H. ALLEN. 



In reporting in 'The Auk' for April, 1905 (Vol. XXII, p. 205) 

 the taking of a Kiunlien's Gull at ]\[oon Island, Boston Harbor, 

 on February 22, 1905, I ventured, though the bird had not pre- 

 viously been recorded from Massachusetts,^ to say that its presence 

 here "was "probably in a sense normal rather than accidental, 

 being simply a southward extension of its usual winter range in a 

 season of unusual severity." The experience of the past winter 

 (1907-08) seems to indicate that Lams humUeni is indeed of nor- 

 mal occurrence on the ^lassachusetts Coast and not by any means 



Dr. Dwi^lit has since recorded an earlier speeinien, a vonntr female taken at 

 Plymouth, Mass., January 5, ISSS, and now in the Rothschild Museum at Tring, 

 England (Auk, Jan., 1906, XXIII, 41).
