Description.
Shell moderately large to large, moderately solid. Body whorl ventricosely conical, outline convex adapically and straight below. Shoulder angulate. Spire of moderate height, stepped, outline straight, apex pointed and sharp. Body whorl smooth. Outer lip thin and sharp. Periostracum thin and translucent.
Ground colour white to cream. Body whorl with narrow brown (cream to yellowish brown) spiral bands from base to shoulder. Overlying spiral rows of variously sized and shaped brown to dark brown markings fuse into variably prominent interrupted spiral bands, below shoulder and above centre. Spire whorls white to brown, early whorls white to pale brown. Post nuclear sutural ramps white or cream with brown radial streaks and blotches. Aperture pale pinkish; exterior pattern visible on the outer lip margin. Periostracum brown and translucent.
Distribution.
Nevill & Nevill (1874)
reported this species for the first time from the Andaman Islands.
Röckel
et al.
(1995)
recorded
one specimen
from Tuticorin and another from Bay of Bengal; the exact locality of the latter was not given.
The specimens described herein were collected from Keelakarai and Pamban (
Table 6
) by trawling in
40– 60 m
.
Remarks.
Conus pretiosus
is extremely rare and probably restricted to
Gulf
of Mannar. Fishermen of Pamban consider it a rare species and differentiate it from other cones by naming it as ‘Pamban vallapoo’.
