Retusa sp. #2

Maximum size: 1.5 mm.
Identification:
The
shell
of this species has an involute apex plus fine axial ribs and
spiral striae. The animal is translucent cream.
Natural history:
Retusa sp. #2 is
known from only one animal found in a sand sample taken off Keehi
Lagoon, Oahu and two shells found in sand samples from depths of 10-20
m (33-66 ft) on Maui.
Distribution:
Maui and Oahu.
Taxonomic notes:
There
is
some question whether this is actually a Retusa (perhaps a juvenile
haminoeid, instead?). It was first recorded in Hawaii from a sand
sample collected at Black Rock,
Maui by CP (shells only).
