Range: S. Australia, W. Port Bay (Victoria) to Cape Leeuwin (W. Australia).
Description: Moderately small to medium-sized, moderately light to moderately solid. Last whorl ventricosely conical, outline moderately convex adapically and less so toward base. Shoulder usually carinate, rarely angulate. Spire of moderate height to high, often stepped; outline straight to slightly concave. Larval shell of 2-2.25 whorls, maximum diameter 1-1.2 mm. Postnuclear spire whorls carinate except for first 2-3 whorls. Teleoconch sutural ramps flat, with 2-3 increasing to 4-8 variably arranged spiral grooves, often weaker and with spiral striae in latest whorls. Last whorl smooth, except distinct spiral ribs on basal third, paired and grading to ribbons toward centre.

Ground colour white to pale pink. Last whorl with fusing pale violet-brown or orange-brown clouds concentrated on both sides of a subcentral spiral ground-colour band. Larval whorls white. Postnuclear sutural ramps with radial streaks matching last whorl pattern in colour. Aperture pink, violet, or orange-brown.
Periostracum light brown, thin, translucent, smooth.
Habitat and Habits: In 7-80 m; on sand substrate. Reported to feed on fishes (Coleman, 1975).
Discussion: C. clarus resembles C. cocceus and C. anemone. C. cocceus has a generally broader and often ovate last whorl (RD 0.60-0.71; PMD 0.71-0.85), convex spire outline, rounded to indistinct shoulder, and generally broader larval shell (1.2-1.5 mm). C. anemone mainly can be distinguished by its angulate to subangulate shoulder, its tuberculate first 2-8 postnuclear whorls, and its sculptured last whorl up to the shoulder.

This section contains verbatim reproductions of the accounts of 316 species of Conus from the Indo-Pacific region, from Manual of the Living Conidae, by Röckel, Korn and Kohn (1995). They are reproduced with the kind permission of the present publisher, Conchbooks.
All plates and figures referred to in the text are also in Röckel, Korn & Kohn, 1995. Manual of the Living Conidae Vol. 1: Indo-Pacific Region.
The range maps have been modified so that each species account has it own map, rather than one map that showed the ranges of several species in the original work. This was necessary because each species account is on a separate page on the website and not confined to the order of accounts in the book.
