Some Cestodes from Japanese Selachians. Including Five New Species

Abstract

Several years ago I collected cestodes parasitic in Selachians found in Japanese waters. Most of them were mature and well preserved. The specimens are referable to ten species, of which five belong to known species and five are new to science. Since the published descriptions of the known species are not entirely in accord with my observations, and some of the species are not satisfactorily described anatomically, I shall re-describe the known forms briefly in the following pages.
