This closeup of the aperture in a living individual shows the anus and papillae which could look like retracted gills inside the opening. The anterior end of the animal is to the left. In this view the mantle has been almost completely retracted from covering the shell.

-
Here is the same shell, dissected out of the animal. Anterior is to the left. There is not an obvious groove around the margin of this shell but there are a series of small concentric grooves, including on the margin. The anterior and posterior ends of this shell do not turn up but slope down less steeply than elsewhere on the shell.
