a few, again, the twosides are nearly equal. The shells of Tellina (PL2, Figs. 10,11) may be recognized by their roundedoutlines, the position of the beaks, and the minuteteeth by which the valves hinge. In the wedge-shells, which, though small, are conspicuous by theirbeautiful coloring, the shell is clearly wedge-shaped,with nearly direct outlines. One of the rarer shells of the coast, although ex-tending in its range from Maine to Florida, is thedelicate Pandora (PL 2, Fig. 9), which can be almostimmediately recognized by the fiatness of its beau-tifully-arched valves, and their pearly structure.Observe that one valve is considerably smaller thanthe other.

THE SHELL-FISH OF THE COAST. 45 OYSTERS, SCALLOPS, MUSCLES, AND ARKS. The oyster is so familiar to everybody that itscarcely needs description. Still, there are a num-ber of points connected with its structure and his-tory which may not be generally known, and mayconsequently be touched upon with advantage. Inthe first place, let it be said that there are two gen-erally recognized species or varieties on our coast,—one known as the Virginia oyster, of an elongatedform, and the other, deeply scalloped, the [Northernoyster (Ostrea borealis). But the shell of the oystervaries so greatly, depending for its form so muchupon the shape of the object upon which it immov-ably attaches itself in later life, that it becomes amatter of great difficulty to determine the properlimits of specific variation; and, indeed, as far asthe two forms above noted are concerned, it is verydoubtful if they do not in reality belong to a singlespecies. In both, as in nearly all oysters, the leftvalve is the la
