Chondropoma simplex Pfeiffer, 1852

Four specimens at NHMUK, unnumbered, seen by the author in 2004, and bearing Pfeiffer’s handwriting are probable syntypes; however, these specimens could not be found in 2016 (pers. comm., J. Ablett). The specimens were collected by Sallé in “St. Domingo.” Bartsch (1946) referred several specimens at NMNH to this species. Examination of the NHMUK and NMNH shells showed them to be members of Chondropoma and not of Parachondria .
