Popis

Range: Although Trincomalee is the usual locality given, the actual range is not yet definitively known. According to local fishermen, its true distribution seems more towards the south than the Trincomalee area, in scattered places in deeper water than the type species. Civil war and vague indications usually given by fishermen make most information unreliable. Habitat: On sandy bottom at 30-40 m deep.

Description: Shell is solid, stocky, ventricose measuring between 60 and 80 mm long. Protoconch orange coloured of 2.25 whorls, slighty shorter than the type species. Spire is short. Teleoconch of four whorls, the body whorl being very swollen. Suture is deep and almost channeled forming a distinct subsutural ramp with sharp coronations which are the spiny projections of axial ribs at their adapical extremities. Sculpture of axial ribs on the spire larger and less numerous than on the type species, 16-17 on the penultimate whorl. Aperture is semilunar forming 0.70 of the total length. Outer lip and columella are similar to the type species. Pattern and colour are slighty paler than the one of type species, with a less prominent dorsal blotches. Animal: Not available for study.

Comparison: Shape, number of whorls and structure of the suture are sufficient for an easy identification when the features are typical.
To north of Yala, a newly discovered population of cloveriana s.s. bears many intermediate characteristics with a squat shape and a slight tendancy to have a spiny suture. The lack of field observations does not lead us to assert that this population represents the beginning of a variation towards cloveriana gabryae .
Remarks: L. cloveriana gabryae remains rare only because the northeastern part of Sri Lanka is still insecure due to civil unrest.
