Dole Plantation tree snail

The length of the shell attains 24.5 mm, its diameter 14 mm. (Original description) The shell is sinistral, minutely perforate, and somewhat solid, with an acuminately ovate-conical form and an acute apex. Its surface is shining and marked by delicate incremental striae; under a lens, it exhibits extremely close, minute, decussating spiral striae. The whorls of the protoconch are faintly cross-lined. The shell is white and is encircled below the periphery by a brownish-black band. At and above the periphery, it bears more or less numerous, delicate chestnut-coloured spiral lines, which become fainter on the middle whorls and obsolete above. There are 6½ convex whorls, narrowly margined above and separated by a deeply impressed suture. The body whorl is somewhat inflated, roundly angulate at the periphery, and flattened at the base. The aperture is oblique and roundly ovate, with a flattened basal margin. It is white internally and exhibits the brown markings of the exterior. The peristome is acute, angulate at the periphery, and slightly thickened internally; it is expanded, with narrowly reflexed basal and columellar margins. The columella terminates in a long, flexuous, white plait. When extended during locomotion, the animal is longer than its shell. The mantle is intensely black, with a broad yellow outer margin and a conspicuous orange spot at the centre of the margin. …
