Oliva barbadensis is a species of sea snail, a marine gastropod mollusk in the family Olividae, the olives.[2]

Description

Original 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.
Size: approximately 40 to 50 mm. in length.
Holotype: Length 50 mm, width 21 mm, trawled from 200 meters depth
off St. James, Barbados Island, by research vessel. USNM 841427.
Discussion: Oliva barbadensis is closest to Oliva drangai from Tobago,
but differs in being a larger, more inflated species, and by having a much darker and more elaborate color pattern."[3]

off the west coast of the island."[4]

This marine species occurs off French Guiana.

Etymology

"Named for Barbados Island, West Indies, the type locality."[5]

"This new species is one of the deepest-dwelling olives in the western Atlantic
