CRENELLA BROWN, 1827

FIG. 12

A single small cast is questionably identified as the genus Crenella based on its shape, size, and radial scultpure indicitative of the genus. No extinct species of this genus have been reported from California and the oldest recorded fosssil occurrence of the modern species is from the Pliocene (Moore 1983). This specimen likely represents a new species but without better specimens it does not warrant naming at this time.
