Description
Original description: on page 126, Living Olive Shells of the World
Oliva (Strephona) barbadensis Petuch & Sargent, new species
(Plate 20, Figures 19, 20, 21, 22)
Description: Shell of medium size for subgenus, heavy, thickened, fusiform in shape, body somewhat inflated, wider at midsection than at shoulder, spire elevated, protracted; color yellow to yellow-tan, overlaid with variable amounts of fine brown triangles in a netted pattern; some specimens with large zig-zag areas of bright yellow; body whorl with two bands of darker brown zig-zags; spire whorls with tan-colored callus; shoulder and edge of suture with pale blue patches, corresponding to sutural scalloping pattern; protoconch large; interior of aperture white; columellar area white with 18 to 25 thin plicae.
Holotype: Length 50 mm, width 21 mm, trawled from 200 meters depth off St. James, Barbados Island, by research vessel. USNM 841427.
Etymology: Named for Barbados Island, West Indies, the type locality.
Discussion: Oliva barbadensis is closest to O. drangai from Tobago, but differs in being a larger, more inflated species, and by having a much darker and more elaborate color pattern. This new species is one of the deepest-dwelling olives in the western Atlantic and is known only from deep water surrounding the Barbados seamount.
Size: Approximately 40 to 50 mm in length.
