This shell is stated to occur on the coasts of Fo-kien and Quang-tung. Messrs. Gumming and Lovell Reeve (both since deceased), who have examined it, concur in referring it to Haliotis Junehris, a New Holland species, figured by. the latter gentlenjan in his beautiful Conchologia Iconica, sect. Haliotis, pi. xii., tig. 38. The shell of Haliotis is also much used for inlaying pfijner mdc/ii work, &c. The section of any pearly shell exhibits an immense succession of tine and smooth layers. If poli-shed or worn ever so little, these iaminfe will be cut through, and their edges will present a series of parallel lines. In the nacreous shell of Haliotis the layers are corrugated, so that a single layer might serve to give the pearly effect. In porcellanous shells the entire structure is composed of layers of cells, much metamorphosed, arranged in three distinct strata, the direction of each of which is different. When seen in section, each stratum is found to be composed of many vertical plates, arranged sometimes transversely, sometimes lengthwise, according to the ; Genus Stomatia. The shell of Stomatia resembles Haliotis, but has no perforations, merely a simple furrow; the surface is rough and spirall
