Type material. Entrance to Bull Harbor, Hope Island (N end Vancouver Island), Rupert District, British Columbia, Canada (50° 54.1' N, 127° 56.3' W), intertidal to 2 m, J.H. McLean & I. Cowan, 21 May 1963, holotype LACM 3401 (ex LACM 1963-29.19), 16.6 mm, lv, and 4 paratypes LACM 3402 (ex LACM 1963-29.19), lv. Other paratypes (from type locality): 1 lv IRSNB I.G33460/ MT.3575 and 1 lv MNHN-IM-2014-6477.
Distribution. British Columbia, Canada, Vancouver Island, and Port Dick, S. coast Kenai Peninsula and Prince of Wales Island, Alaska, intertidal to 37 m depth.

Description. Shell small for genus, up to 16.6 mm in length, length/width ratio 2.1—2.4. Shape lanceolate, broadly ovate, lightly built; subsutural ramp very narrow, tabulate, weakly concave. Color light brown with lighter colored axial lamellae, edge of aperture white, brown or light brown within. Spire high, with 1.5 protoconch whorls, up to 6 moderately broad, convex, shouldered, lamellate sculptured teleoconch whorls. Suture impressed, partially obscured by axial lamellae of following whorl. Protoconch small, whorls rounded,
smooth, maximum width 650 (im. Terminal lip shallow, almost straight. Axial sculpture of teleoconch whorls consisting of moderately high, thin, strong abaperturally curved lamellae, broader, higher at shoulder. First teleoconch whorl with 9—10 lamellae, second with 9—11, third to last whorl with 10-12 lamellae. Spiral sculpture absent except P1 producing somewhat more developed axial lamellae at shoulder. Aperture moderately small, broadly ovate; columellar lip narrow, smooth, rim adherent. Outer lip moderately broad, smooth within; siphonal canal short, broad, straight, very weakly recurved dorsally, broadly open ventrally, with low axial lamellae over entire length.

Remarks. This differs from B. pacificus by the smaller size, shorter siphonal canal, light brown coloration, and its crested axial lamellae that project at the shoulder. It differs from B. multicostatus (Eschscholtz, 1829) (Fig. 14H) in having a comparatively smaller shell with a higher spire, a shorter siphonal canal and more numerous axial lamellae on the last teleoconch whorl (10-12) compared to B. multicostatus (8-9).
Etymology. Named after Vancouver Island where the specimens were collected.
