Description
editFor terms see gastropod shell
The 3–4 x 1.5–2 mm. shell has 5–7 convex whorls which are slightly more convex than those of Hydrobia acuta neglecta. Smaller shells with 5 whorls are slightly less slender than those of Hydrobia neglecta. The suture is deep. The aperture is rounded upside (or only slightly pointed) and attached to the last whorl. The lip is weakly developed. The shell is very finely striated and in colour translucent, glossy yellow-brown, usually hidden by a matt deposit.
Certain identification requires dissection. The penis has a pointed tip, not a blunt tip as in Hydrobia acuta neglecta.
