Description. Shells are up to 55 mm in length, dirty-yellow, greenish-gray, yellowish-brown, sometimes with rose shade; inflated, romboid-oval in plan, thin, smooth, without plication anteriorly. Beak is strongly curved and cut with small foramen, which is sloped to pedal valve (epithyrid foramen). Pedicle is thin, smooth, long. In brachial valve middle septum extends forward from the top of shell to 1/3 of the shell length.
Distribution. L. vancouveriensis is widely distributed in boreal zone of Pacific from the Navarin Cape along the Asian coast to Peter the Great Bay, Tsugaru Strait and Sagami Bay, and along American coast to San-Diego at the depths of 2–1600 m.
Ecological data . In the northern part of the Sea of Japan the species is usual and numerous at the depths of 52–142 m (up to 68 sp./m2) from Peter the Great Bay to the Tatar Strait. Off Peter the Great Bay at the depths of 700–1000 m the species forms oligomixed association with spots of highest density up to 3000 sp./m2 (Popov, 1975).
