30 XE8T8 AND EOO8 OF 



Almost as large a species as the Glaucous Gull or Burgomaster. It breeds on the 



Pacific coast from Washington Territory northward. The nests are 



built on the shelving rocks of high cliffs. On the Aleutian Islands they 



are found among the tall grass on the highest parts of the islands, while others are 



built on projections of rocks. Sometimes there is little or no attempt at nest- 



making, the eggs being laid in a slight depression of (he ground. On Bering Sen and 



ands. on the Kaintschat kan coast, this species breeds all around the 



shores. Eggs have been found as early as the middle of .May. These are said to be 



of a more greenish tinge and the spots more numerous and better defined than in 



those of iiln nni.\. Size 2.88x2.03. According to Mr. Ball this is a very abundant 



species throughout the Aleutian chain, but more numerous in the eastern halt of 



the group. Young birds nearly fledged were secured at Kyska in July. He states 



bit of this and other species breeding on isolated rocks and small islands, 



is accounted for by the immunity thus gained from the ravages of foxes on the eggs 



OUDg. Uarely more than three eggs were found together, and were laid on al- 



any little depression of the ground, with little or no attempt at a lining.

This new species of Gull, first described by Mr. William Brewster,* is like 

 iiliiiii-rxiTiitt, but somewhat smaller. It is recorded as being quite common in the 

 upper Cumberland water, where it breeds, placing the nests on shelving roeks of 

 high cliffs. The eggs are said to be the same as those of ii
