Material examined. Over fifty broken valves, up to 17 mm from EI (BK), plus the Hawaiian type specimen ( USNM) .

Diagnosis. Shell small (up to 17 mm in length), thin, very fragile, elongated oval. Anterior and posterior ends rounded; parallel dorsal and ventral margins. Exterior surface consisting of commarginal growth lines and fine radiating striae dorsally, while on the central and posterior portions of the valve they are stronger, incised oblique lines which divaricate to form triangles. Interior is translucent and the exterior sculpture can been seen through the valve. Hinge consists of two cardinal teeth in each valve. In the LV the anterior tooth is strong and hook-like, while the posterior is obscure and divergent. In the RV the anterior tooth is also strong and hook-like, but in the posterior it is divergent and erect. Color white.

Remarks. The Easter Island material conforms to the holotype of S. baldwini ( Figs. 42 H–I) originally described from the Hawaiian Islands, although the EI material is rather small compared to the Hawaiian maximum size of 27.5 mm.

Habitat. Dredged at 180–220 m in fine sand collected off the southwestern coast near Orongo , Easter Island. 27 o 11’58” S, 109 o 29’28” W .

Distribution. At present Solecurtus baldwini is only known from Easter Island and the Hawaiian Islands— E2.
