Six New Species of the Order Septibranchia (Bivalvia) from the Northeastern Pacific Ocean

Abstract

Six new species of septibranch molluscs are described from the northeastern Pacific Ocean. Three species of Cuspidaria are proposed, assignable to Cuspidaria (s. str.), Rhinoclama and Luzonia. A fine large Cardiomya is assigned to a new subgenus, Labromysa. Poromya (s. str.) is recorded for the first time from the Northeastern Pacific, and a new species of the subgenus Dermatomya is described.
