The Committee are indebted to Professor Chr. Fr. Lütken, of the Universitetets Zoologiske Museum, Copenhagen, for a list of the birds killed against the lantern of the lighthouse of Stevns, on the projecting part of Zealand, marking the limit between the Baltic and the Grönsund Belt, in the autumn of 1882. Professor Lütken, in forwarding the list, remarked that his late lamented predecessor. Professor Reinhardt, made arrangements with a physician, Mr. Antander, residing at the small town of Storeheddinge, seven Danish miles south of Copenhagen, in the neighbourhood of Stevns Klint and the lighthouse of Stevns, for forwarding any birds found killed to the museum, with the following result:—

* Is often seen swarming around the lighthouse at the time of its migration—six or seven on this night flew against the panes without being killed, and two others were caught alive. About forty Redbreasts and Wheatears were caught on the same night, but set at liberty again in the morning. On clear moonlight nights nothing at all is caught or found.
† According to Mr. Antander were not sent to museum.
Mr. Gätke sends the following notes of an extraordinary migration of the Silver Gamma Moth, Plusia gamma, across Heligoland in August, 1882:—
On Aug. 13th, at 1 a.m. till 4, thousands on thousands passed the Heligoland lighthouse, travelling E. to W. From 11 p.m. on the 15th, till 3 a.m. on 16th, millions, like a snow-storm, all belonging to the same species, passed forward in the same direction. Again, on the 18th, from 11 p.m. till 3 a.m. on the 19th, thousands on thousands were observed under the same circumstances. Some scores caught for identification were all in most perfect plumage; no fading or abrasion.
