. Cassell's natural history. Animals; Animal behavior. NATURAL VERRDCOSA, WITH ITS ANIMAL. ovate, and tumid, the valves grooved or lamellate; the marf»ins of the shell finely crenulated ; the lunule is distinct, the hinge thick, with three teeth in each valve; line of the mantle has a short angular bend. One hundred and seventy-six species of this genus are found living, with a world-wide distribution, in the British Islands, North Sea, Mediterranean, Cape of Good Hope, iSrc. Tliey are found buried a few inches deep in sand at low water, and range to 100 fathoms; they are all edible. The North American Indians used to make coinage ("wampum") of the sea-worn fragments of V. mercenaria by perforating and stringing them on leather thongs. Long Island was called Seaivar hackee (or Shell Island) by the Moheyan Indians, who i-esorted to it to collect Seawan ("wampum shells"), from which they made their purple beads. V. mercenaria ranges from Cape Ann, Mass., to Delaware Bay; it is called the " round clam "â "; It sells from 37| to 62i cents the bushel. Genus Cytherea. The shell is like Venus, but the margins are smooth; the border of the mantle is plain, and the siphons are partly united. One hundred and thirteen species are living. Genus Artemis. At first sight Artemis looks like a Lucina, but the outline is almost circular, and it has a deep angular pallial fold ; the hinge is like CytJierea ; the foot is large and hatchet- shaped ; the siphons are united ; the margin of the mantle is plaited. Artemis ranges from northern to tropical seas, and from low water to 100 fathoms. One hundred species are known. Genus Lvcinopsis. The shell is less elegant in outline than in Artemis, and thinner ; the right valve has two diverging teeth, the left has three ; the mantle- fold is vei-y deep; the siphons are longer than the shell, and diverge from one another; their orifices are fringed. Ten species are living in North Am
