NEW SPECIES OF MOLLUSCS FROM THE AMAKUSA MARINE BIOLOGICAL LABORATORY, REIHOKU-CHO, AMAKUSA, KUMAMOTO PREF., JAPAN

Abstract

During the biological survey of the sea around Tomioka Peninsula, Amakusa, we have collected more than 921 molluscan species as listed in Part. 1. Mollusca of the Fauna and Flora of the Sea around the Amakusa Marine Biological Laboratory edited by the writer and Mr. T. KIKUCHI in 1960, in which more than sixteen species are new to science. While some had been reported already in two other papers, most of them have never been described elsewhere. Therefore, the writer has given the descriptions for these species in the following lines.
