clade Euthyneura clade Panpulmonata clade Eupulmonata clade Stylommatophora clade Sigmurethra Helix pudibunda[1][2][3] Nitor pudibunda is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicarionidae.
Cox's description of the shell of a specimen of N. pudibunda, published in A Monograph of Australian Land Shells, 1868.
[1]α 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.
The smoothness, want of carina, pinkish colour, and callous columella are the chief points of distinction between this and H. Moretonensis and H. subrugata.βThe species is found in eastern Australia, most commonly along the coasts of Queensland and New South Wales, from Cooloola to Lismore.
