 valid record exists for this vicinity. Rye, N. Y. March 3, 1894 (Porter, Auk, 

 XII, 1895, P- 76; see also Dwight, Auk, XXIII, 1906, p. TiI- where a second speci- 

 men reported by Porter, and incorrectly recorded by Chapman as leucopterus, 

 is given as L. kuinliciii). 



Kumlien Gull (Lanis kninliciii). There are two records of this rare Gull 

 for this vicinity, one is based on an immature male shot March 8, 1898, at Rock- 

 away Beach, L. I. CBraislin, Ank, XVI, 1809, p. 150 and XXII, 1905, p. 168,
