RECENT exhaustive investigations into the fauna of filtration plants, which are being conducted by the Water Examination Department of the Metropolitan Water Board, under the direction of Colonel C. H. H. Harold, have resulted in the discovery at the Lea Bridge Waterworks of Eucrangonyx gracilis S. I. Smith. This species has been recorded only from Canada and the United States. It was collected in October and November 1936 by Mr. A. C. Gardiner, from whom I obtained the following notes on its distribution in the filters and its appearance in life. Specimens were submitted for identification to Prof. A. Schellenberg, of Berlin, to whom my thanks are due.
