Identification. Test moderately high, with deep anterior notch. Apical disc posteriorly positioned. Anterior ambulacrum distinctively sunken, two-series of irregularly arranged, large pores, associated with tube feet; paired petals sunken, wide at internal fasciole, tapering distally. Periproct opening at truncated end, variable in shape. Internal fasciole conspicuously long, subanal fasciole shield-shaped, with four pore-pairs, pointed at end; anal fasciole extending along periproct, onto upper side, separated from subanal fasciole. Spines uniform. Live specimen brownish, denuded test white. Global maximum size. Maximum test length 90 mm . Global distribution. From northern Norway along European coasts into Mediterranean and Morocco , South Africa , Japan , New Zealand and southern Australia ; from littoral to 500 m ( Döderlein 1910 ; Schultz 2010 ). Remarks. Samples identified through current study extend previously known distribution northwards towards Sodwana Bay. Differs from E. capense in large shield shape internal fasciole and frontal notch.
