Abstract

<p>Two new species of the genus Calagrassor Kantor et al., 2013 are described. Calagrassor analogus n. sp. is distributed in Japan, the East China Sea and Taiwan, and has been previously confused with Aulacofusus hiranoi (Shikama, 1962). Differences in protoconch morphology serve to distinguish C. analogus n. sp. from A. hiranoi and differences in sculpture serve to distinguish this new species from C. aldermenensis (Powell, 1971) and C. hayashii (Shikama, 1971). A second and hitherto unknown species is described from Japanese waters as Calagrassor hagai n. sp. Differences in spiral and axial sculpture serve to distinguish it from other known species in the genus.</p>
