Winge on Birds at the Danish Lighthouses.— Mr. Herluf Winge’s 
fourteenth annual report on the migration of Danish birds is of special 
interest to students of American ornithology on account of the further 
records that it contains of the little known Petrel, Oceanodroma crypfto- 
leucura Ridgway, added to our fauna by Mr. Wm. Palmer in the last 
number of ‘The Auk.’ Two of these birds struck Danish lightships 
during the autumnal migration of 1896, one at Drogden, a few miles 
south of Copenhagen, on September 19, and another at Kobbergrunden, in 
the Kattegat, on October 11. After comparison of these specimens with 
the 16 skins of O. lewcorhoa in the Zodlogical Museum at Copenhagen 
Mr. Winge concludes that the characters of O. cryptoleucura are purely 
individual and that typical examples of the so-called species may be 
expected to occur among any of the colonies of Leach’s Petrel. It is 
extremely doubtful whether this view of the relationship of the bird to 
O. leucorhoa can be sustained, as the characters described by Mr. Ridgway 
and Mr Palmer can hardly be reconciled with any such hypothesis.
