Its peculiar shape, which suggested the specific name, will readily distinguish it. 
The last whorl is more or less malleated or grooved, and frequently there may be seen 
transverse raised lines running parallel with the suture.

This species is very abundant in moist places in forests, both in Raiatea and Tahaa, 
A closely allied form occurs high up in the mountain ravines on Moorea. It is never 
found on foliage. 
Though Pfeiffer gives the habitat “ Tahiti,” there is not much, if any, doubt of its 
having been collected, by Cuming, at Raiatea. So common a species could scarcely 
have escaped the notice of that experienced collector. 
'fhe measurements, color and texture agree very nearly with Pfeiffer’s description. 
Like the jireceding species, which it closely resembles, it varies in the size of adults, 
longer or shorter .«pire, more or less strongly convex body-whorl, and in color from 
pale straw-yellow to whitish or corneous. The last whorl is sometimes slightly flattened 
beneath the suture, and frequently malleated. The strife are more developed than in 
pudorma. The Moorea specimens are more or less incrusted with dirt, and are mther 
darker-colored, the strife cofirser, and the aperture more regularly ovate.
