TABLE 4 in Bouchetaria (Gastropoda: Cypraeidae), a new genus for the Riddle cowry, B. aenigma (Lorenz 2002), from the deep waters of the Mozambique Channel

TABLE 4. Shell comparison of B.aenigma with phylogenetically closely related species (see Figure2). The conchologically dissimilar Ipsa childreni (J. E. GRAY 1825) (see Figure 6 h) is excluded. Nesiocypraea midwayensis not obtained for molecular analyses is included for morphological comparison with Nesiocypraea teramachii.
