Fig. 9

A Dorsal view of a specimen of Erymnaria sp. 1 under water, shows the diverging inner lines beyond the hinge line, which trace the septiform crura and (indistinctly) the outer lines which trace the crural supporting plates (NMSG-F-14502). For comparison see the analogous markers (B and C) in two specimens of Erymnaria polymorpha in Cooper (1959, tabl. 18B, figs. 34 and 25)
