Description. Shell slender, with canal longer than aperture. Shoulder strongly angulate, usually with upturned spines, but aspinose specimens known. Single upturned spine of terminal lip larger and more outwardly projecting than earlier formed spines. Length 15-20 mm.
Type Locality and Type Specimens. Santa Catalina Island, California, 40 fathoms. Lectotype (here designated) UCBP 10611 [syntypes were reported by Coan and Bogan, 1988:277]. Material Examined. Santa Maria Basin, Phase I, sta. 1,98 m (1 immature). Other material: 52 lots in the LACM collection.
Distribution. Monterey Bay, California (37°N), to Isla Cedros, Baja California (28°N). Ocenebra crispatissima: Isthmus Cove, Santa Catalina Island, California, 33 fathoms; holotype: CAS 064468.
Habitat Rocky bottoms, 10-100 m.
Remarks. The species concept is based on figures of Dall (1921), not of type material, which has not been illustrated. Ocenebra crispatissima Berry was based on an aspinose specimen. Although both Ocinebrina barbarensis and O. crispatissima were treated by Radwin and D'Attilio (1976:120) as synonyms of Ocinebrina foveolata (Hinds, 1844), Ocinebrina barbarensis is a well-differentiated species, having the longest canal of the northeastern Pacific species.
