Abstract

Two extinct species of the genus Cerion Röding, 1798, found by first time in subfossil state for Holguin province are described. Both were found in lithologies that date from the Neogene to Quaternary period. The first species, Cerion alejandroi sp. nov., spotted in El Júcaro, Ramón de Antillas, is discussed comparatively with other extant species: Cerion geophilus, Cerion disforme disforme, Cerion milerae and Cerion proteus, showing as distinctive characters: imbrication in the whorls, a visible sutural cord and low and sharp ribs. The other new species, Cerion seguii, located in El Uno, Nicaro, is discussed in comparison with: Cerion pygmaeum, Cerion paredonis, Cerion portillonis and Cerion pretiosus. In this case exhibiting as diagnostic characters: a small and spherical shell, more numbers of whorls at the apical region, with the next to last, moderately more enlarged.
