Appearance: Very spiny, to 3 mm in length (Figs. 7E, 11F); anterior width to mm, height mm or less; rounded anteriorly, somewhat truncated posteriorly; re- tracted mouth opening triangular; pedal pit a lateral slit (Fig. 7F); pedal groove covered by numerous long epidermal spicules; mantle cavity opening suhterminal. spicules in brushes on each side, copulatory spicules often protruded (Fig. 7G), dorsoterminal sense organ often externally visi- ble. Cuticle and epidermis: Cuticle 60 /*m (Fig. 8A spicules 3); skeletal spicules less than 200 long and to 8 /nm wide, hidden externally under thickly set, upright spicules; barbed spicules numer- ous, upright, in longitudinal bands on each side of mid- dorsal crest of crossed upright s
