From the other species of Eurypterus these two forms differ in their long, gradually tapering, terete body and the small size of the swimming legs. The variability in the size and position of the eyes is commented upon in the preliminary description. Note might also be taken of the confusing variabilit}^ in the outlines of the carapace. A survey of a great number of carapaces shows that the variability of features which in other species exhibit considerable stability, is for the most part due to the great convexity of the carapace of this species and the resulting various modi- fications under the ififluence of differing directions of compression. The accompanying text figures are inserted to illustrate this fact. In figure I the carapace has been vertically and gradually compressed so that the eyes are projected on the horizontal plane directly below their original position.
