ON A NEW SPECIES OF LAMELLARIA (L. UTINOMII, N. SP.) FROM SHIRAHAMA, WAKAYAMA PREFECTURE, JAPAN (MOLL., GASTROPODA)

Abstract

In 1960 a Gastropod specimen was handed over to me for study by Prof. H. Utinomi, Director of the Seto Marine Biological Laboratory of the Kyoto University. The present report is the result of observation on this specimen. I wish to thank Prof. Utinomi for his kindness in giving me an opportunity to observe this specimen, in which peculiarity in the form of the radula was revealed. I am also grateful to Dr. T. Kuroda who kindly assisted me in studying the known species of this genus by his rich experience on the Molluscan fauna of Japan. I wish to thank Dr. G. M. Davis, of the Academy of Natural Sciences of Philadelphia, who kindly aided me in seeing the relevant literature.
