Abstract

Differences in shell shape, spiral sculpture and periostracum serve to distinguish Ovulatibuccinum Golikov & Sirenko, 1988 from Bathybuccinum Golikov & Sirenko, 1988, and the former is hereby elevated to the generic level. Bathybuccinum bicordatum Golikov & Sirenko 1988 and Ovulatibuccinum fimbriatum Golikov & Sirenko 1988 are recorded from off northeastern Honshu, hereby extending the range of these species to the south and into Japanese waters. Three species are described as new: Bathybuccinum higuchii n. sp. (northeastern Honshu, Japan), B. yadai n. sp. (East China Sea, southwestern Japan) and Ovulatibuccinum perlatum n. sp. (northeastern Japan to Russia), representing a remarkable range extending of the genus Bathybuccinum to the south.
