Clavus bilineatus

Clavus bilineatus is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

Description
The size of an adult shell varies between 12 mm and 24 mm. G.W. Tryon thought this species to be a synonym of Clavus pulchella (Reeve, 1845) (described as Drillia pulchella). He stated that the differences were only in the tuberculations being less sharp and the color not so bright, with a brownish tinge.

Distribution
This species occurs in the Indo-West Pacific, off the Philippines and Taiwan, and also off Papua New Guinea and Australia (Queensland).
