Shell: Shell moderately small, more compact than Neverita duplicata; proportionately higher (see Fig. 4 D); light to medium grey, apex dark, area below suture often decorated with reddishbrown band; aperture ovate, large, less oblique than in N. duplicata; umbilical callus triangular, brownish, crossing umbilicus to connect to body whorl (Figs. 4 DF); umbilicus deep, centered by moderately small umbilical cord terminating in a funicle; deeply excavated, longitudinally striated umbilical canal anterior to umbilical cord, separated from wall of body whorl by distinct ridge or keel; umbilical channel often retains periostracum.
Distinctive characters to separate N. duplicata from N. delessertiana morphologically: ratio of height to width, shape of umbilical area; less consistently, shape of umbilical callus.
