MANY specimens of a small amphipod crustacean, Euthemisto compressa, Goes, have been forwarded to me by Mr. T. H. Nelson, of Redcar. On May 23 and 24 these were washed ashore in incredible numbers on the coast of Yorkshire, where they lay from Saltburn to Teesmouth—a distance of ten miles in drifts several inches deep. The pools were alive with the crustaceans, and to the east of Redcar a fisherman was seen raking them into heaps, and wheeling away barrow-loads to put on his garden as manure. In the sea hundreds at a time could be scooped up in one's hands.
