On a New Species of Gammarus (G. Trigrinus) from Droitwich District

Abstract

The new species of Gammarus here described was first noted in 1931 by Prof. H. Munro Fox, to whom I am indebted for the opportunity of examining it. He found it in abundance in the Droitwich district, living in the brackish waters of the River Salwarpe near the town, in the Canal, and in Wyken Slough near Coventry.
