DESCRIPTION
Shell of small size for the genus,
8.1 mm
high,
5 mm
wide. Protoconch abraded of 1.8 whorls, with two spiral keels.Teleoconch of 4.5 turriculated whorls, spire high, conical, with flat sides. Aperture damaged, oval, siphonal canal long, open; twisted, imbricate fasciole, umbilical chink closed.Teleoconch spiral sculpture of 14 cordlets and two major cords, irregularly disposed; 6 cordlets and the adapical cord visible above the aperture. Axial sculpture of 8-10 broad orthocline ribs. Shell ground colour orange-pinkish.
REMARKS
I have been unable to identfy with certainty this shell. It is a partly broken juvenile which superficially resembles to
Coralliophila abnormis
(E. A. Smith, 1878)
and to juveniles of
C. fearnley
(Emerson & D’Attilio, 1965)
but differs in the stronger spiral and axial sculpture, and the wider protoconch at the base. Due to the lack of additional material I refrain from describing a new taxon. Th e shell is in relatively good condition, but its habitat (shallow or deep waters) cannot be defined.
