Natica View in CoL (ss) sp. (an operculum)

( Fig. 10C, D View FIG )

MATERIAL EXAMINED. — Brazil, Espírito Santo: off Itaúnas , 18°59’S, 37°50’W, 295 m, MNHN, 1 operculum ( MD55 sta. DC75 ; coll. Bouchet, Leal & Métivier, 27.V.1987) GoogleMaps .

REMARKS

An operculum was collected (14.4 × 8.3 mm), and its analysis shown that it does not belong to anyone of the known species in Brazilian coast and neighborhood. It barely resembles the operculum of Natica ss, as that of N. vitellus (Linnaeus, 1758) , the type species of the genus, has an elaborated set of folds in outer edge ( Fig. 10C View FIG ), and is relative smooth in remaining regions. The erosion of its inner surface, which lacks the usual organic matrix that normally covers it ( Fig. 10D View FIG ), shows a certain degree of transportation or long time after death. The relative good preservation allows the deduction that the enigmatic species occurs in the region. Because of the obvious incompleteness of data, a formal description of the species is here considered premature.
