    ORDER II. Bibalves. MYA._—TRovuGH-SHELL, oR GAPER. DESCRIPTION OF PLATE IV. Fig. 1. M. Arenaria. Fig. 3. M. Corrugata. Fig. 2, M. Pubescens. Fig. 4. M. Aurita. Shell bivalve, generally gaping at one end. THIS genus is placed by Linnzus the first on the list of Bivalves; the number of its species amounts to forty. The principal characteristic of the Mya consists in its gaping at one end: the next general distinguishing mark is, its having a single, broad, patulous tooth, pro- ceeding from beneath the beak. It is much wider and broader at one end than the other; and the broadest end has an excavation, which gives it the appearance of the bowl of a spoon. The form of the Mya varies exceedingly: some are oblong and truncated; others, again, are orbicular or round; and many are angularor eared. .
