Range: New Caledonia.

Description: Small to medium-sized, light to moderately light. Last whorl conical; outline almost straight; right side may be slightly convex, left side slightly sigmoid. Shoulder carinate. Spire of moderate height; outline concave. Larval shell of about 3 whorls, maximum diameter 1.1-1.2 mm. About first 4 postnuclear whorls tuberculate, following whorls carinate. Teleoconch sutural ramps slightly concave, with closely-set, strong radial threads crossing obsolete spiral striae. Last whorl with wide, axially striate spiral grooves, narrower, weaker or obsolete adapically; 4 closely-set, punctate spiral grooves just below the shoulder.

Ground colour white to beige. Last whorl with about 6-8 broad, brown spiral lines on the ribbons between the basal spiral grooves; occasionally irregular brown blotches in the ground-colour zone. Larval whorls beige. Postnuclear sutural ramps with irregular brown radial blotches. Shoulder edge sometimes ornamented with brown spots.

Periostracum thin, translucent.

Habitat and Habits: In 300-560 m.

Discussion: C. boucheti differs strikingly from all other Indo-Pacific Conus species in its colour pattern of basal basal brown spiral lines on an otherwise uniformly beige last whorl.

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.
