Comitas

Comitas kamakurana, copyright Korina Sangiouloglou.


Belongs within: Conoidea.

Comitas is a genus of relatively large, tall-spired conoids with a sculpture of long fold-like axials and a leaf-shaped operculum (Powell 1966).

Characters (from Powell 1966): Shell moderately large to very large, up to 95 mm, elongate-fusiform, with tall spire and moderately long, straight to slightly flexed, unnotched anterior canal. Protoconch papillate, of two smooth whorls, carinate or subcarinate over last whorl. Adult sculpture of long fold-like axials, crossed by dense spiral lirae. Suture submargined by very weak fold at most. Sinus moderately deep, rather broadly U-shaped, on shoulder slope, but nearer to periphery than to suture. Operculum leaf-shaped, with terminal nucleus. Radula of "wishbone"-type, paired marginals but with distal limb detached.
