| Abstract |
Zafra ornata lives gregariously among barnacles, keel worms and other marine encrusting organisms (Fig. 1). Being minute, it tends to be overlooked by the casual observer. Its size ranges from slightly over 2 mm to about 4 mm, and can be misidentified as juveniles of the sympatric dotted dove-shell (Euplica scripta). The shell of Zafra ornata is beige with a white spiral band above the keel. This spiral band is quite distinctive when seen in the field at close range (Fig. 2). The last whorl of the shell is ornamented with random wavy brown lines (Fig. 3-5) which appears to be constant in this species (Pease, 1868). The original description and type figure of Pease (1868), as well as the type specimen of the species housed at The Academy of Natural Sciences (MolluscaBase, 2019) match the Singapore samples very well. |
