Aclophora grandiosa ( Laseron, 1954 ) — Laseron 1958: 628 , fig. 177. Triphora grandiosa ( Laseron, 1954 ) — Kosuge 1965: 212 . Type locality. Australia , New South Wales , Woolgoolga . Type material. AMS C.103119, holotype . Distribution. Australia ( Laseron 1954 ; Laseron 1958 ; Kosuge 1965 ), Japan ( Kosuge 1965 ). Remarks. The genus Notosinister is of masculine gender, therefore the name should be Notosinister grandiosus . Marshall (1983) added that the type specimen is worn and lacks the early whorls and most of the last teleoconch whorl. Based on the available characters, he considered this name a junior synonym of Inella xystica Jousseaume, 1884 .
