They are translucent, faintlyrosy-rayed when young, with a yellowish lustrous surface anda gentle curvature of the ventral margin when full grown.

The Chinesehave long used these sheets in lieu of glass for window panes.Specimens of the young shells may be obtained in curio stores.Soaking loosens the thin lamina? that compose them. 422 THE SHELL BOOK TLATE V111
