Spectamen bellulus is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.[1]

Description

The height of the shell attains 6 mm, its diameter 8.5 mm. The rather thin, shining shell is umbilicated and has a conoidal shape. The six whorls are convex, depressed-canaliculate above, and terraced. The first whorl is whitish, the remainder whitish, beautifully ornamented with regular, equidistant, radiating, somewhat flexuous radiating rosy streaks. The shell is spirally delicately striate. The body whorl is carinated. The white base is radiately striate, somewhat convex. The aperture is subquadrate, and smooth inside. The lip is thin. The narrow columella is scarcely arcuate, forming an angle with the basal margin . The umbilical area is funnel-shaped, white, carinated, the carina subnodulose.[2]

Distribution

This marine species is endemic to Australia and occurs off New South Wales
