Contents |
[edit] Distribution
This subspecies is endemic to Fiordland in the South Island of New Zealand.
[edit] Habitat
This top snail is found at depths of between 7 and 15 m.
[edit] Shell description
The shell is larger, taller-spired, and of lighter build than the typical Micrelenchus caelatus subspecies, differing also in having a more pronounced peripheral angulation, and more numerous spiral cords, seven to nine on the penultimate, and these are flat-topped and smoothy, never granulose.
Coloration is variable; buff, with continuous or interrupted rose to purplish-brown spirals, and sometimes with radiate splashes of cream.
The shell height is up to 7 mm, and the width is up to 5.5 mm.
