Point Barrow, congregating in thousands along the shore to feed 

 upon small Cielenterates and Crustaceans that were washed up on 

 the sands. When we again reached Point Barrow, September 8th, 

 these birds were in the height of their southern migration, and 

 bands composed of from fifty to one hundred individuals were con- 

 stantly passing, but this time paying little attention to the food that 

 was still abundant along the shore. Xema Gulls were not seen at 

 Herschel Island until August 28th. The absence of immature 

 birds was a striking fact; almost all of these Gulls that we observed 

 were adults. Two young, however, were shot at Point Barrow Sep- 

 tember 12th. Hab., Pacific coast of North America from Monterey, 

 California, N. to Point Barrow, east, New York, Great Lakes, 

 (casually to Bermudas and Peru). 



71. Sterna paradisaea. Arctic Tern. 



The first representative of this species was seen June 6th, longi- 

 tude 141° W., latitude 52° 37' N. The poor bird seemed to have 

 been battling with the storm for some time and to be completely 

 tired out ; it alighted in our rigging and remained with us all day. 

 By June 20th Terns were very common, and eight or ten could be 

 counted from the deck of the vessel at one time. Two specimens 

 were shot at Port Clarence, Alaska, July 8th. Terns were quite 

 abundant at Point Barrow August 12th and at Herschel Island 

 August 27th. Hab., circumpolar regions, south in winter to Cali- 

 fornia. Another species of Tern supposed to have been Sterna aleu- 

 tica was observed quite frequently in the Bering Sea. We were un- 

 able to obtain a specimen however. 



DIOMEDEIDJE. 



82. Diomedea albatrus. Short-tailed Albatross. 



The first Short-tailed Albatross was observed May 26th, about 

 eighteen miles off Cape Flattery. Two were seen June 1st in longi- 

 tude 134° 16' W., latitude 51° 6' N. ; the day following another was 

 observed. This completes the record of all seen during our entire 

 voyage. These birds, unlike the Black-footed Albatross, do not fol- 

 low after a vessel. Hab., North Pacific from California to Alaska. 



81. Diomedea nigripes. Black-footed Albatross. " Goonie." 



On May 27th, about one hundred miles northwest of Cape Flat- 

 tery, these birds of the open sea were first sighted. From that time 

 until June 21st they were always in evidence about our vessel. The 

 last " Goonie," however, deserted us when we came in sight of the
