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."

Distribution
"Endemic to Barbados, where it is common at 100 to 160 meters depth,  off the west coast of the island."

This marine species occurs off French Guiana.

Etymology
"Named for Barbados Island, West Indies, the type locality."

Habitat
"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."This carnivorous, scavenging Olive responds readily to baited traps.
