Description.
Shell medium sized to moderately large, solid to moderately heavy. Body whorl conical to broadly conical, outline convex near shoulder, straight below. Shoulder broad, subangulate to angulate. Spire low to moderate height, sharply pointed, outline slightly concave. Aperture moderately narrow and with almost uniform width, outer lip sharp and straight. Body whorl with variously spaced, weak or incised or often punctuate spiral grooves on apical third.
Ground colour white. Body whorl with spiral rows of mostly bright orange rectangular spots or bars, often alternating with white markings. These colour markings usually fuse into spiral bands in each side of the centre. Shoulder and spire with radial markings matching bars on last whorl in size and colour. Base bluish-white. Aperture white, usually with pink tones. Periostracum orange, thin and smooth.
Distribution.
Bruguière (1792)
first reported
C. tessulatus
from the Malabar coast.
Dautzenberg (1937)
noted a specimen from Madras (at IRSN).
Röckel
et al.
(1995)
reported a specimen from Madras and another from
India
without locality data.
Kohn (1978)
reported museum deposited specimens collected from Tuticorin (at BMNH) and
Tranquebar
(at ZMUC).
The specimens described herein were collected by trawling in
5–20 m
from stations 4, 5 and 19 and at depths beyond
50 m
from other stations (
Table 6
). In Keelakarai, specimens were collected by diving in
5–8 m
on sand and coral rubble bottom.
Remarks.
Conus tessulatus
occurs generally at stations with the large fishing harbours. No depth data from Indian waters was available from the previous reports. However, in this study,
C. tessulatus
was mostly obtained at depths of
5–
50 m
.
