Holotype and Type Locality— LACMIP 41573.1 , LACMIP Type 13647 ( Figs. 7J–L View Figure 7 ), length 12.7 mm, width 8.2 mm, height 6.9 mm. LACMIP Locality 41573 (ex CSUN Locality 1573), Crescent Formation , Doty Hills , Lewis County, Washington. The type locality of this species occurs in the lower McIntosh Formation , northern Doty Hills , Lewis County , southwestern Washington, and not, as stated in Groves (2011: p. 50) as in the Crescent Formation. The lower McIntosh Formation is middle Eocene in age ( Squires and Goedert 1995).

Occurrence— Middle Eocene, “Transition Stage” to “Tejon Stage,” Lewis County, southwestern Washington .

Etymology— Originally named for colleague James L. (Jim) Goedert (Gig Harbor, Washington).

Description— Shell small and slightly inflated. Dorsum highly arched with maximum height slightly posterior of center; maximum width nearly centered. Spire covered. Aperture wide for size Denticulation coarse with smooth interstices; outer lip with 14 teeth, inner lip with 12 teeth. Anterior canal shallow. Posterior columella area moderately inflated. Anterior ridges prominent. Posterior ridges slightly reduced. Posterior canal deep. Basal marginal callus moderate on outer lip; base rounded (Groves, 2011: p, 50).
