Haplocochlias is a genus of sea snails, marine gastropod mollusks in the family Skeneidae.[1]

Description

The solid, subperforate shell has a turbinate shape. The aperture is rounded. The thick peristome is continuous and exteriorly varicose. The columella is not callous.[2]

The shell is small to minute (1–6 mm in height), turbiniform, with a closed to narrowly open umbilicus lined internally with spiral cordlets. The protoconch comprises about three-quarters of a whorl and is either smooth or bears fine spiral cordlets. The teleoconch has a rounded to slightly angular periphery, ornamented with numerous spiral cords and fine axial striae, with minute tubercles present in the interspaces. The aperture is prosocline, with a continuous peristome. The columella is sometimes reflected toward the umbilicus, broadening at its base, and in some species displaying a depressed area where it meets the umbilical cord. The outer lip may be either broad or delicate, and is crenulated or anteriorly expanded.[3]
