60 NORTH AMERICAN FAUNA. [no. 19. 



except the center of chest and abdomen. Head markings slate-black, 

 distinctly defined and numerous, the most characteristic being one 

 that covers the entire nasal region, a V on the pileum, a W on .the occi- 

 put, and a somewhat interrupted U on each side of the throat. On 

 the upperparts the markings become pale seal brown, and with lighter 

 tips render the lower neck, sides of breast, flanks, and anal region 

 grayish. Bill l)rownish black; tip of bill, tarsi, toes, and palmations 

 whitish; nails and edges of scutellfe of tarsi and toes hair brown. 



19. Larus Philadelphia. Bonaparte Gull 



I saw several small black-headed gulls, probably this species, in the 

 Inside Passage May 29. I took a Bonaparte gull at Caribou Crossing 

 on June 24 and saw several others. We saw one on Lake Marsh 

 July 1, a few young at St. George Island October 3, and found them 

 common at Unalaska October -i-S. 



20. Xema sabinii. Sabine Gull. 



Osgood found a dead bird of this species on the shores of Chilkat 

 Inlet June 1. The specimen, unfortunately, was not in a condition to 

 permit its preservation, but it was carefully identified at the time and 

 showed no apparent variance from the description and figure in 

 Ridgway's Manual. 



21. Sterna paradisaea. Arctic Tern. 



We saw a largo flock of terns in the Inside Passage May 39, and 

 two days later at Skagway saw a few more, securing two, which proved 

 to be of this species. ■ At Bennett, between June 15 and 20, we fre- 

 quently saw two or three, and 1 was informed that arctic terns bred on 

 a small lake near Log Cabin, British Columbia. We found a breed- 

 ing colony of about twenty on a small rocky island lying in the 

 entrance to Windy Arm, Lake Tagish, July 1. I found four single 

 eggs (three fresh and one well advanced in incubation), one set of two 

 (one fresh and the other at point of hatching), and also a young bird 

 which had just left the shell. There were no nests; the young bird 

 and eggs were in the short grass on the top of the island. Except a 

 single bird, seen at Lake Marsh and probably belonging to this colony, 

 we did not meet with terns again until August 27, when I found this 

 species common at the Aphoon mouth. A single tern with injured 

 primaries was seen frequentl}^ at St. Michael up to September 21. 

 The downy young differs from the description given in Baird, Brewer 

 and Ridgway's 'Water Birds,' in having the forehead plain dusky, the 

 chin whitish, the basal half of bill, tarsi, and toes salmon pink, and the 

 rest of })ill and nails black. 



22. Diomedea albatrus. Short-tailed Albatross. 



A dark-brown albatross, probably the young of D. albatrus^ joined 

 the Co7'win October 1, about 150 miles from St. Michael. It was soon
