The holotypes of three species inquirendae siphonophores collected in Japanese waters and described by Tamiji Kawamura were re-examined. It is considered that Bathyphysa japonica is not a valid species because there are no characters that distinguish it from other Bathyphysa species; Athorybia longifolia is an incorrectly described specimen of A. rosacea; and Forskalia misakiensis is a wrongly described and badly preserved specimen, probably of F. edwardsi.
