Etymology— Originally named for Lindsey T. Groves (Natural History Museum of Los Angeles County, Mala- cology Department).
Description— Shell small (17 mm length), oval, high- est at mid-point of dorsum. Base flattened with promi- nent concavity near anterior end. Spire covered, spire area coincident with small pit. Aperture straight, except for bending leftward in posterior region. Denticulation strong, outer lip with 16 teeth, inner lip with 12 teeth, sculpture extending halfway to shell margin, and ribs slightly stronger on inner lip. Outer lip callus prominent and with dorsal ring circumscribing entire shell ( Squires and Demetrion 1992: p. 31).
Remarks— The two known specimens of Bernaya grovesi have good to excellent preservation.
