Shoulder subangulate to sharply angulate. Spire usually low; outline concave to convex. Larval shell of about 2 wide whorls. Teleoconch sutural ramps concave, with densely set, fine to pronounced axial threads crossing 3-4 major spiral grooves in later whorls; additional spiral threads on last ramps. Last whorl with closely spaced spiral threads from base to 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.
