their tips white, as is terminal portion of the secondaries ; lower 

 parts and tail feathers pure white. Length thirteen inches and a 

 half, wing eleven. 



A specimen of this elegant Gull was shot at Raynor South 

 in the month of July, 1837, and I am not aware that any other has 

 ever been observed in this vicinity. It is said to breed along the 

 coast of the Arctic seas, and in Newfoundland. "This interesting 

 species of Gull was discovered by Captain Edward Sabine. It was 

 first seen on the 25th of July, at its breeding station on some low 

 rocky islands, lying off the west coast of Greenland, associated in 

 considerable numbers with the Arctic Tern, the nests of both birds 

 being intermingled. It is analagous to the Tern, not only in its 

 forked tail and choice of breeding place, but also in the boldness 

 which it displays in the protection of its young."— Fauna Boreali

Specific Character. — Bill stout, compressed, gamboge yellow, with 

 a carmine patch toward the end of the lower mandible ; from the 

 frontlet feathers to the end two inches and a quarter, tarsi two and a 

 half. Adult with the plumage pure white, " excepting the back and 

 wings, which are grayish-blue ;" edges of wings, and the quills to- 

 ward the end white. Young, white, the upper parts slightly tinged 

 with pale yellow, lower parts with brown ; feet flesh color. Length 

 of young twenty-seven inches, wing seventeen and three quarters. 



This large and powerful Gull is chiefly confined to the northern 

 part of the hemisphere. The adult rarely visits the United States, 

 and then only in winter, and I am not aware that it has ever been 

 observed on Long Island ; and it is but seldom that the young oc- 

 curs with us. " It is notoriously greedy and voracious, preying not 

 only on small fish and birds, but on carrion of every kind. One
