Abstract
An examination of a syntype of Cuspidaria cochinensis Preston, 1916, focusing on the characters of the hinge, supports the transfer of this species to the family Corbulidae. Recently collected material from the Cochin Backwater is used to describe the shell and anatomy of the adult form. The ctenidia are composed of two demibranchs, both flat and homorhabdic, this further confirming that this species is eulamellibranch and not septibranch. The most appropriate generic placing of this species is in Cuneocorbula; thus, it is the first recorded extant species of the genus.
