Though allowed a place in the New England list for 

 many years, upon more or less unsatisfactory evidence, 

 this species was with many others eliminated in 1875 by 

 Dr. Brewer, with the remark : " This, it is now generally 

 conceded, has no claim to be placed in the avi-fauna of 

 New England. Exxept as accidental in Greenland, it is 

 not even North American " (Pr. Bost. Soc, xvii, 1875, p. 

 453). But this statement is too sweeping. Dr. Brewer 

 himself has the pleasure of correcting it, in recording 

 the capture of a specimen on the Georges fishing banks^ 

 off the Massachusetts coast, in July, 1878 (Bull. Nutt. 

 Club, iii, 1878, p. 188). This specimen was brought into 

 Gloucester, and examined by Prof. Baird.
