Type locality. “ad Nauclai (lat. 25°15′, long 92°30′)”.

Material examined. Many shells ( NHMUK), Cherrapunji, Assam, coll. Godwin-Austen.

Remarks. Parietal callus reaches ca. half of penultimate whorl, smeared onto it. Basal swelling situated relatively close to peristome, slight, but clearly visible. Parietal lamella strong, outer portion rather straight or slightly curved in palatal direction, inner part curved towards columella. Palatal wall with a strong, sharp, elevated ridge that runs together with the parietal lamella. A small denticle is attached to the palatal ridge and situated on the basal part of the sinulus. Columellar lamella almost horizontal, deeply situated, sharp, its blade is visibly in oblique view to the aperture. An additional, blunt denticle is situated on the columellar peristome, near the columellar-parietal junction. Based on the aperture shape, the presence of a basal swelling, and the arrangement of the apertural barriers, this species is a member of the genus Sinoennea .
