Figure 28 in A new species of Cribrarula (Gastropoda: Cypraeidae) from New South Wales, Australia

Figure 28. Holotype of C. gravida sp. nov. and its cast made of clear nail polish, used to protect the glossy exterior surface of the shell against the slightly etching buffer used during in situ digestion of the dried tissue in the shell (Moretzsohn and de Couet, in prep.). After the digestion is complete, the polish coat is peeled away, and if done carefully, a perfect cast of the shell can be obtained. Note that the polish removed the China ink used to write the catalog number on the shell labrum. The cast was also returned to the Australian Museum, and now is part of the lot AMS C. 91000.
