Popis
Description. Relatively large, transparent, extremely flexed; whorls 15, body whorl slightly inflated; aperture long. Length 6-9.5 mm.
Type Locality and Type Specimens. Departure Bay, British Columbia. Holotype: USNM 207771. M clonal la grippi: Newport, Orange County, California; holotype: USNM 203665. Balcis titubans: Anacapa Island, California; holotype: SBMNH 34554. Material Examined. Santa Maria Basin, Phase I, sta. 4, 393 m (1). Other material: 53 lots in the LACM collection.
Distribution. Attu, Aleutian Islands, Alaska [LACM 86-312] (53°N), to Isla Cedros, Baja California [LACM 71-156] (28°N). Habitat One LACM record (LACM 151103) indicates association with a large holothurian Cucumaria sp. Most records in the LACM collection indicate a depth of 50 m or less. Common in the northern part of the distribution, where it may occur in the intertidal zone.
Remarks. This species has the most extreme curvature of the northeastern Pacific species, differing also from other species in its relatively broad final whorl. The synonymy given above is a based on my examination of type material.
