Clionella subcontracta is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae.

[clarification needed] The dark yellowish-brown shell is elongate but has a narrow base.

The suboval aperture measures about ⅓ the total length of the shell.

A spiral striation or groove at the periphery, which also winds up the spire just above the suture, is usually more strongly marked than the rest.

This marine species occurs off Namaqualand to Port Alfred, South Africa.
