Range: Southern Red Sea (Jeddah area, Saudi Arabia, and Dahlak Is., Eritrea) and Gulf of Aqaba, N. Red Sea.

Description: Small to moderately small, light to moderately light. Last whorl ventricosely conical to conical; outline slightly convex; left side concave near base. Shoulder angulate to subangulate. Spire usually of moderate height, often slightly stepped; outline straight to slightly convex. Larval shell of 1.75-2 whorls, maximum diameter 0.8-0.9 mm. About first 2 postnuclear whorls tuberculate. Teleoconch sutural ramps flat, with 1 increasing to 3-4 strong spiral grooves. Last whorl with spiral ribbons on basal third or half, grading to ribs near base.

Ground colour pale pink. Last whorl with spirally aligned brown dots and wavy brown axial lines partially combined in tent-like flammules; lines fusing into 2-3 indistinct spiral bands or increasingly reduced. Larval whorls and first postnuclear sutural ramps white. Following sutural ramps with brown radial lines and streaks crossing outer margins. Aperture pale pink.

Periostracum pale brown, thin, translucent, smooth.

Animal uniformly light pink (Fainzilber & Mienis, 1986; Hamann, pers. comm., 1989).

Habitat and Habits: In 30-40 m, on coarse sand mixed with coral rubble near coral reefs. In the Jeddah area C. hamanni ranges deeper than in the Gulf of Aqaba.

Discussion: C. hamanni may resemble subadults of C. locumtenens, but the latter differs in its reticulate pattern, more angulate shoulder, rather concave spire outline, and the weaker spiral sculpture on the teleoconch sutural ramps.

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.
