Zemira
bodalla
Garrard, 1966
Description:
Shell with rounded whorls, with a deep channel at the suture.
No axial sculpture; entire shell with widely spaced spiral
grooves and a single deep groove at anterior of body whorl.
Outer lip smooth, with
a small spike at the termination of the deep groove on unbroken shells;
columella smooth, terminating in a broad siphonal notch.
Background colour white, with interrupted brown spiral bands on
the whole surface, these sometimes coalescing into axial flames. Umbilicus
absent or a narrow chink. Operculum
corneous, large, filling the aperture.
Size:
Up to 28 mm in length.
Distribution: Endemic to
Australia
; Swain Reefs,
Queensland
, to Danger Point (
Tweed
Heads), NSW.
Habitat:
Known from 146-350 metres. Uncommon.
Comparison:
This species is very similar to Z.
australis, differing by having stronger and more widely
spaced spiral grooves, the umbilicus being slightly open, and
showing a more intense colour pattern.
Z. australis occurs in
south-eastern
Australia
, as far north as Fraser
Island, Queensland, at depths down to 146 metres.
Z. bodalla occurs in southern Queensland, from Point Danger on the
NSW-Queensland border and northwards, at depths of 146-350 metres.
Hence their latitudinal ranges overlap a little, but they occur at
different depths.
