(B). 1 serrated spicules from above mouth, 2 barbed spicules and 3 long upright spicules from mid-dorsal region, 4 S-shaped and pointed ovate spicules from edge of mantle cavity, 5 spicules from beside pedal groove, 6 skeletal spicule. In (A), spicules from paratype (MV F83481) except upright spicule on right from another specimen from type locality. In (B), spicules from paratype (MV F83476) except upright spicule on right from another specimen from type locality. 100 jam in length, with a short, narrow base (spicule 5); spicules from opening of mantle cavity S-shaped and pointed ovals (spicules 4). Radula (2 specimens examined): With 21 to 22 rows, teeth 40 to 45 jam by 10 jam, with 4 to 6 denticles (Fig. 7H). Copulatory spicules (7 specimens examined): copulatory spicules paired, 2 per sac; one long, rodlike, distally tapered and curved, to 750 /urn long by 25 jam wide; the other nearly as long, the distal half flared into a hood with a thickened distal ridge, width 104 jam (Fig. 9A-D). Notes on anatomy: Large dorsal sinus present, extending far anteriorly. Midgut cecum paired anteriorly, becoming single at level of radula. Mantle cavity surrounded by sub- epithelial goblet cells. Reproductive system. As in E. mimus. Remarks. Morphological differences between E. bassen- sis, E. mimus, and E. sierra are discussed under Remarks for E. mimus. Eleutheromenia mimus sp. n.
