Description.
Shell medium sized, moderately solid. Body whorl conical; outline convex adapically; left side slightly concave near base. Shoulder angulate, weakly granulose. Spire of moderate height, outline concave. Body whorl with strong, with prominent widely spaced spiral ribs and ribbons, strongly granulose.
Ground colour white. Body whorl overlaid with yellowish brown irregular axial streaks and blotches arranged in two spiral bands. Early postnuclear sutural ramps white to pale brownish. Aperture white. Periostracum brown, thin and translucent.
Distribution.
Massilia (1993)
reported a specimen of
C. asiaticus
(as ‘
C. lovellreevei
’) from Madras.
The specimens described herein were collected from Vembar (
Table 6
) by trawling in
5–15 m
, mainly on the sandy bottoms.
Remarks.
Some specimens of
C. asiaticus
appear similar to
C. inscriptus
. However,
C. asiaticus
can be distinguished from the latter by the irregular yellowish brown axial streaks and blotches on its body whorl, while
C. inscriptus
has regular spirals of both brown dots and dashes or sometimes either dots or blotches.
Massilia (1993)
has reported a specimen of
C. lovellreevei
from the southeast coast of
India
. There have been no records in the literature on the distribution of
C. asiaticus
from
India
. The geographical range of
C. asiaticus
is given as "
Japan
to
Philippines
and
Vietnam
; Queensland" and for
C. lovelreevei
: "off Madras,
India
" (
Röckel
et al.
1995
). The specimen described above collected from Vembar has the characteristic features of
C. asiaticus
thus disproves the statement of
Röckel
et al.
(1995)
that 'because of their disjunct geographical ranges, the slight differences in shell morphology between
C. asiaticus
and
C. lovelreevei
justify seperation'. The specimen presently collected extends the distribution of
C. asiaticus
to southeast
India
.
