Description
Cox's description of the shell of a specimen of N. pudibunda, published in A Monograph of Australian Land Shells, 1868. "Shell perforated, depressly-turbinate, thin and transparent, very smooth, showing under the lens very faint curved lines, and traces of still fainter spiral lines, shining, pinkish or flesh coloured; spire broadly conical, rather acute; 6 whorls, flatly convex, last not descending in front, the periphery shewing nearly obsolete traces of a keel, below convex, glossy, generally opaquely milky-white about the umbilicus, which is minute and shallow; aperture diagonal, somewhat squarely-lunar, pearly within; peristome simple, acute, columellar margin very slightly triangularly dilated and reflected above. In old age, white and callous.

Diameter 0.65[1.651cm]; height 0.55[1.397cm] of an inch.

Habitat. Richmond River.— MacGillivray. Moreton Bay.— Masters.

The smoothness, want of carina, pinkish colour, and callous columella are the chief points of distinction between this and H. Moretonensis and H. subrugata."

Distribution
The species is found in eastern Australia, most commonly along the coasts of Queensland and New South Wales, from Cooloola to Lismore.
