Equivalve: Inequivalve, RV slightly more convex than LV. Equilateral: Subequilateral beaks at or just in front of the midline. Previous studies on the gonadal cycles of Mya arenaria have divided the developmental se­ quence into five morphologically distinct phases: inactive, active ripe, spawning, and spent (Ropes and Stickney 1965; Porter 1974). Since semantic problems arise withthis usage, several terms are redefined for use here. The term "indifferent" is Mya arenaria, t.s. of intestine and gonads prepared microscope slide.
