Aulopoma helicinum is a species of small land snail with an operculum, terrestrial pulmonate gastropod mollusc in the family Cyclophoridae.[1]
Distribution
It is endemic to Sri Lanka.[2]
Description
It is about 14mm in length.[3]
(Description in German by Kobelt) Height 6.5 mm; diameter 13 × 10 mm.
The shell is widely umbilicate, almost disc-shaped, thin, and striated, pale horn-colored with brown marbling and a band. The apex is styliform, bluish-brown. There are four rounded whorls; the body whorl descends anteriorly and is detached. The aperture is oblique and almost circular; the lip is continuous, straight, thin, and sharp. The operculum is more tightly coiled than in Aulopoma itieri, with convex whorls that are densely folded on the exterior.[4]
