Original description


Partula mooreana was originally described by William Dell Hartman (1817–1899) in 1880. 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.
