Of the Poached-egg Cowries there are several species, the most common is called by naturalists Ovulum ovum, Eig. 4, from ovum—an ^^g] the back of this shell is much elevated and rounded; it is smooth and white; the inside is orange brown. Some of the Poached-egg group are of a more slender and angular shape, as, for instance, that called the Gibbous, ' 0. Gibhosa;) the moon when more than half-full, is called gibbous, that is, rounded unequally, as this shell. Tew shells undergo greater changes, both of shape and colour, during the ])rocess of growth, than the Cowries, which are called in Prance Porcelaines, on account of their high i)olish and brilliant hues; a single species in different stages of development, might well be, and often is, taken for distinct shells. Much might be said about the Mollusks \ \^/ which inhabit them, but our present subject has ^^^ rather to do with their outer covering than their internal stnicture. The most rare and valuable, if not the most beautiful, of these Cowries, is the C. aurora, ov aurantium, Zklorning-dawn, or Orange Cowry, a jxrfect specimen of which has been sold for fifty guineas. There is a \Qry curious shell called the Common Weaver's Shuttle, {Oculum volva,) generally included in the Cyprea family; of this a represent- ation will be found on Plate YII, Fig. o.
