Holotype and Type Locality— LACMIP 22341.1 , LACMIP Type 13644 (Figs. 5G–I), length 52.7 mm, width 40.0 mm, height 26.3 mm. LACMIP Locality 22341 [ex UCLA Locality 2341], Crescent Formation , southwest end of Discovery Bay, Jefferson County, southwestern Washington.

Occurrence— Middle lower Eocene (“Capay Stage”), southwest end of Discovery Bay , Jefferson County, south- western Washington .

Etymology— Originally named for Richard L. Squires ( CSUN, Geological Sciences, professor emeritus).

Description— Shell of medium to large size, constrict- ed on anterior end; maximum height near center of shell; maximum width slightly posterior of center; aperture wide, straight; dentition medium to coarse; labral (outer) lip with 24 teeth, columellar lip with 25 teeth; anterior terminal marginal callus (Groves 2011: p. 47).

Remarks— This species is known only from its ho- lotype, which has moderately good preservation. Postburial crushing damaged the anterior portion of the aperture and also dorso-basally distorted the holotype. Perrilliat et al. (2003: pl. 1, figs. 5, 6) figured a specimen identified as Bernaya (Bernaya) obesa ( Deshayes, 1866) [hypotype IHN 5459] but is outwardly more similar to B. squiresi . Unfortunately, poor preservation prevents a positive identification. A poorly preserved outer lip fragment ( LACMIP 41599.2), which could be B. squiresi , from the Crescent Formation, LACMIP Locality 41599 (ex CSUN Locality 1599), Middle Fork Satsop River, Dry Lakes quadrangle, Mason County, Washington is noted. B. squiresi represents the northernmost occurrence of the genus in Cenozoic strata and the only representative of the genus described from Washington.
