This is largely due to the terete form of the body that apparently is without preabdominal expansion. A few specimens [pi. 22, fig. 8] indicate that there was a slight expansion, but it seems to have found its expression mostly in an increased vertical convexity of the body.

This convexity both of the dorsal and ventral sides producing the subcircular section of both preabdomen and post- abdomen, is shown by several specimens which are but slightly compressed. A species quite similar to our type in both form of body and size is E. pygmaeus Salter from the Downtonian (uppermost Ludlow) of Great Britain. Its carapace, however, seems to have been a little longer I II III IV V.
