Shell sinistral, elongate oval, white, bulb reduced, last whorl ascending, lamellar system reduced. Description. Shell sinistral, elongate oval, white to light yellowish; protoconch acute, granulated, consisting of 2 whorls; last whorl not constricted, bulb reduced, inconspicuous; teleoconch sculpture of widely spaced ribs, ribbing pattern slightly wider on the last two whorls; last whorl strongly ascending; aperture circular, in a central position, broadly adhered to the last whorl, peristomial rims connected; umbilicus closed, periomphalum narrow; lamellar system completely reduced; bulb lamella very weak. Operculum. Outer surface with concentric rings of lamellae, internal surface concave and smooth inside, OD = 0.52. Measurements. Lectotype godeffroyana (Fig. 74): H = 3.4; D = 1.84; PH = 1.36; PD = 1.29; W = 5.5. Figures 74-78.

Palaina godeffroyana resembles Palaina pomatiaeformis , which, however, differs by its larger and elongate shell, denser ribbing pattern, and the presence of a basal columellar denticle.
