Abstract

RECENT letters by Dr. Kemp and Mr. F. S. Russell1 and Mr. A. C. Stephen2 have directed attention to the occurrence of Atlantic organisms on the coasts of Great Britain and Ireland. It may be of interest to add another example to the list. While the Fishery Cruiser Muirchu of the Department of Lands and Fisheries was engaged in taking physical observations off the south-west coast of Ireland, fifty miles south-south-west of Fastnet Light, on August 9, 1932, considerable numbers of a large salp, 3–8 cm. long, were noticed drifting a few feet below the surface and some were captured. These proved to be the sexual stage of Cyclosalpa bakeri, Ritter. Several other specimens occurred in a tow-netting taken on the same station, and also in another taken seventy miles south-south-west of the Fastnet, suggesting that the shoal may have been twenty miles across. Cyclosalpa bakeri appears to be mainly a tropical species and I do not know of any previous record from British or Irish waters.
