The valves cannot be closed in the living state, and the cloak is ornamented with a vast number of filaments of different lengths, without tubercles ; and further within there is a broad fold which closes the gape of the shell, and even forms a protuberant veil. The foot is small, and the byssus inconsiderable. The LimiE swim rapidly, by flapping their valves. One species in the Mediterranean, of a pure white colour (Oslrea Lima, Linn.), is eaten. Pedum, IJrug.—The shell is similar to Lima, but the valves are unequal, and the most convex only has a deep sinus for the byssus. The animal also is very like that of Lima, but its cloak has only a single row of small slender tciitacula. Its byssus is larger. The one species known is from the Indian sea. Certain fossils may be placed here which have the hinge, ligament, and central muscle of the Ostreas, Pectines, and Limae, but are distinguished by some peculiarities of the shell. The Hiiinites, Defr., seem to be Oysters, or Clams, with small ears and adherent shells, irregular and very thick, especially the convex valve. Tliere is a fossa at the hinge for the ligament. (Four recent species of this genus have been described.) The PJagiosfo7nes, Sower., have the oblique shell of the Limse, flattened on one side, very minute ears, the valves more ventricose, striated, without scales, and the outlet of the byssus less.
