Belongs within: Rapaninae.

Nassa is a genus of marine gastropods found in the tropical Indo-Pacific, living under stones and coral in intertidal and shallow sublittoral waters. The western Pacific N. serta bears strongly beaded spiral ribs on the shell (Wilson & Gillett 1971).

Characters (from Wilson & Gillett 1971): Ovate, spire moderately high. Whorls rounded. Anterior canal broad, posterior canal not notched into lip but formed behind large opposing denticles on parietal wall and outer lip.
