Original description

Partula mooreana was originally described by William Dell Hartman (1817–1899) in 1880. [2] Hartman's original text (the type description) reads as follows:

Partula Mooreana, Hartman.

Shell sinistral, ovate, elongate, thin, translucent, pale yellowish horn-color, apex darker; whorls 5, flatly convex, body whorl, with or without from one to three narrow, pale, brown revolving bands; surface smooth, with fine, oblique striations, which are decussated by crowded waved spiral striae; a narrow white line beneath the suture; aperture hearly half the length of the shell, lip white, moderately reflected, pillar tooth oval, prominent, situated nearest the superior angle, umbilicus open, moderately compressed.

Length 18 mill., diameter 9 mill.

Hab. — Vaianai Valley, Island of Moorea (Andrew Garrett, Esq.).

In one hundred and forty-six species and varieties of Partula represented in my collection, this shell possesses constant and well-marked specific characters. Mr. Garrett informs me that fifteen hundred specimens were all sinistral and dentate. The surface of the shell resembles P. spadicea and varieties from Moorea in possessing the thickly crowded waved spiral striae.

This species is arboreal, and is not uncommon on bushes, in

Vaianai Valley, the metropolis of P. vexillum Pse. = P. stenostoma Ph.

Gastropod shell Part of the body of a gastropod or snail

The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or the shell is reduced such that the body cannot be retracted within (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.
