125 



niches under honldcrs ami on tlie sides of the ciitTs. I t'ound no eggs, 

 although nlan^• nests \vere examined. 



10. Uria troile californica. Californi.\ Mukrk. — Nuinerons among 

 tiie ontlyinii; islands. Many nearly fiosh egt^s were secured on July 28. 



11. Rissa tridactyla pollicaris. Pacific Kittiwakk. — Common 

 about the inland bays and narrows; although many specimens were 

 taken, not only in immature plumage, but in full adult, none showed any 

 signs of breeding. 



12. Larus glaucescens. Glaucou.s-winged Gui,l. — The common 

 Gull of Sitka Bay, and the only one found breeding. The nests were 

 slight hollows in the ground among the tall grass on the higher parts of 

 the islands. These nest-hollows contained a slight lining of dry grasses. 

 Two or three eggs constituted a set. Fresh eggs were found from June 16 

 to August 4. 



13. Larus Philadelphia. Bonaparte's Gull. — One specimen, an 

 immature male, was brought in by my Indian July 21. It was shot out 

 in the open bay and was the only one seen. These small Gulls were very 

 numerous on some parts of the steamer passage from Killisnoo and 

 Juneau, south to Qiieen Charlotte Sound, August 25-27. 



14. Puffinus griseus. Dark-bodied Shearwater. — A female was 

 brought in by the Indian on July 15, and another, July 21. He reported 

 seeing several others. They were in the open baj'. As far as I am aware, 

 this is the first recorded instance for Alaska. 



15. Oceanodroma furcata. Fork -tailed Petrel. — Breeding in con- 

 siderable numbers on St. Lazaria Island, where on June 17, most of the 

 eggs were badly incubated, and several young were taken. (See 'Nidolo- 

 gist,' March, 1S97.) 



16. Oceanodroma leucorhoa. Leach's Petrel. — Breeding in im- 

 mense numbers on St. Lazaria Island, where the eggs were fresh on 



Measurements of O. leiccorhoa from St. Lazaria Island.
