“ This highly elegant and delicate species was first described by us in the Catalogue of the Bligh Collection, at the sale of which a specimen produced five pounds. Latterly, however, the species has become more frequent: the figures are taken from a fine individual in our Museum, procured from China. The pure white of the surface is relieved by a slight iredescent or pearly gloss, similar to that on the scales of many fish: but which is probably concealed, in a state of nature, by a thick and soft epidermis, similar to that of Triton corrugatum, Lam. ”
