“…Echinoderes kozloffi Higgins, 1977 has been reported only from intertidal, diatom-covered rock and gravel sediment of San Juan Island, Washington (Higgins, 1977;Kozloff, 1972), but may occur subtidally as well. Although E. riedli Higgins, 1966 was reported first from intertidal muddy sand along the shores of the Red Sea at Al Ghardaqa, Egypt, I have collections of this same species from subtidal mud near Rovijn, Yugoslavia.…”
