Thalotia conica, common name the conical top shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[1][3]
Description
The solid shell is imperforate and elevated conical. The length of the shell varies between 13 mm and 23 mm. It is pinkish or grayish white with a crimson apex and numerous close longitudinal dark reddish-brown stripes, often cut into tessellations by the spiral grooves of the surface. The spire is straightly conical. The apex is acute. The sutures are linear. The seven whorls are nearly planulate, the last one obtusely subangular at the periphery. The whorls of the spire are encircled by 5 or 6 more or less granose lirae, the body whorl with about 13 or 14. The wrinkles of increment are more or less prominent. The aperture is rhomboidal. The thick peristome is plicate within. The straight columella is denticulate, with a strong basal truncation. [4]
Distribution
This marine shell occurs off Southwest Australia to New South Wales and off Tasmania
