DISTRIBUTION. — Previously considered endemic to the
Galapagos Islands
(
Emerson & D’Attilio 1970
;
Keen 1971
). Range extension to
Austral Islands
in the Indo-Pacific ecoregion, one empty shell in
600-
900 m
.
REMARKS
The single shell collected is worn, partly broken and lacks the tip. It is however perfectly concordant with the type material. Th e
paratype
AMNH 155902 and one specimen in MO coll., have usable protoconchs of 2.5+ and 2.6 whorls, respectively, which allow inferring a planktotrophic development for this species.
