It will appear extraordinary, that this very common shell should have been unknown to Linnæus; and still more, that no other systematic writer should have noticed it, excepting Gmelin, by whom it is placed as a variety of S. gallus, although his S. raninus is obviously made from a bad figure in Knorr of this same shell. On referring to Mr. Dillwyn's account of S. gallus, I find all the references of Gmelin to this shell expunged; and a note at the head of the genus states, that S. raninus is undeserving of notice; thus every trace of the shell, in this work, is altogether lost.

The two lobes at the top of the outer lip form a strong and peculiar distinction of this species: the colour of the mouth is variable; though usually tinged with pink, it is often reddish, or red blended with yellow, and sometimes nearly white; within the upper part of the aperture, round the inner lip, are one or two strong plaits, with sulcated grooves on each side; and near the lobe at the base of the outer lip, the aperture has a few obsolete striæ: the nodules on the body whorl are triangular, and the two nearest the lip are, in general, very large: the channel (or base) is short, and turned up in an oblique direction.

Found, in great abundance, in various parts of the West India seas.
