Taranis mayi, from Verco (1909).

Belongs within: Raphitomidae.

Taranis is a genus of deep-water conoids with members lacking an operculum or radula (Bouchet & Waren 1980).

Characters (from Powell 1966): Shell very small, 2.5-6 mm, ovate-biconic, predominantly medially angulate and splrally keeled, usually crossed by lamellate axials, producing a fenestrate sculptural pattern. Protoconch paucispiral, of barely two whorls, papillate to slightly globose, superficially smooth, but with a microscopic sculpture of closely spaced stippled spiral lirae. Sinus shallow, its apex at the peripheral angle or major keel, and with unequal angles of approach, being steep and straight above, but protractively arcuate below. Pillar abruptly twisted at beginning of a short shallowly notched anterior canal. No colour pattern, white or translucent. Operculum absent.
