In Japanese waters the distribution of 13 species of Euchirella, namely, amoena, bella, bitumida, curticauda, galeata, maxima, messinensis indica, orientalis, pulchra, rostrata, tanseii, truncata, and venusta, have been known (MORI, 1937; TANAKA, 1957; OMORI, 1965; FURUHASHI, 1965; TANAKA and OMORI, 1969). In the present collection a total 13 species listed in Table I are obtained from the Izu region.
