Syrnola cf. subcinctella Nomura, 1936
Maximum size:
5 mm shell
length (mature
shell).
Identification:
This
species has a glossy white shell with a narrow,
spiral brown line
above the suture. Mature shells are decapitate while
juvenile shells
are attenuate. The animal varies from cream to dusky pink with white flecks.
Natural history:
The
shells of Syrnola cf. subcinctella are rare in beach drift but more
common in subtidal
sand samples to depths of at least 52 m (170 ft).
Live animals are
occasionally found in sand samples from Halimeda kanaloana
beds taken at
depths
of around 10-20 m (33-66 ft).
Distribution:
Maui,
French Frigate Shoals and Midway: probably widely distributed in the Indo-Pacific.
Taxonomic notes:
Syrnola subcinctella shells illustrated on-line are very similar to the Hawaiian material but include forms that are not decapitate.
