Mr. Geo. B. Sennett states that he examined an adult mounted 

 specimen of this species at " Koshkonong Place," which was killed 

 late in October, 1882, on Lake Koshkonong, Wisconsin, by Rev. G. E. 

 Gordon (Auk, 1884, p. 98 ). The occurrence of a bird of this species 

 in Wisconsin is, of course, most extraordinary. Its true habitat is 

 the North Pacific ocean, from Vancouver Island northward.
