36 REPORT ON THE MIGRATION OF BIRDS. 
Flock of Guillemots hung about XIV. for a time, and a few 
more seen on 24th. Large numbers of Guillemots and Razor- 
bills, from 16th to 18th, at XX VII., when all left, and after a 
W. gale large numbers on 2d Dec. and again on 31st Dec. 
and seen occasionally till end of January. N.B—Black Guil- 
lemots, one seen at XX VII. on 27th Jan. 1886. We think it 
quite possible Black Guzllemots still breed on Isle of May, 
perhaps one pair.
