126 HAWAIIAN BIRDS. 



gray; wings sooty black; tail grayish; beneath sooty black. Length about 

 13.50 inches. 



Gygis alba (Sparrman). White Tern. 



Included by Mr. Dole in his list of 1869 and found by Palmer 

 breeding upon Laysan and Lisiansky Islands. Doubtless this tern 

 will be found to occur upon the Hawaiian group, at least upon 

 the northern members, as an occasional visitor. 



Description. — Adult. White, eye encircled narrowly with black. Bill 

 and feet black. Length about 13 inches. 



Larus barrovianus Ridgway. Point P>arrow Gull. 



Mr. Bryan reports (Key to the Birds of the Hawaiian Group) 

 two specimens of this gull as having been taken on the island of 

 Kauai by Mr. Francis Gay and a third as being in the Museum of 

 St. Louis College. Tbelatter was procured on the island of Maui 

 by Brother Matthias. These birds would seem to be accidental 

 strays from the Alaskan coast. 



Description. — Adult. Head, neck, tail and under parts white; mantle 

 pale pearl gray. 



In winter, head and neck streaked with brownish. Length about 25-28 

 inches. 



Larus glaucescens, Naum. Glaucous-winged Gull. 



This gull seems to be a rare and irregulaB visitor to the island 

 of Hawaii and probably also to the other islands, especially to 

 Oahu, Every year or two, one or more individuals are seen about 

 Hilo harbor, evidently having followed vessels down from San 

 Francisco. Apparently these wanderers never attempt to return, 

 but their final fate is unknown. 



According to Rothschild, Prof. Schauinsland obtained a spec- 

 imen of this species on Laysan. 



Description. — Adult. Mantle pearl gray; head and under parts white; 

 primaries with small white spots at the tips; in winter top of head and 

 hind neck streaked with dusky. Length about 25 inches. The young
