Abstract
Some time since, in the summer of 1884, Mr. Jex, a collector of fossils employed by Mr. Robert Damon, F.G.S., of Weymouth, obtained from the Lower Carboniferous Shales of Eskdale, a new and most interesting form of Merostomatous Crustacean belonging to the genus Eurypterus. It has been secured for the Geological Department of the British Museum (Natural History), and I now propose to submit a brief description of this very interesting specimen.
