Epidirona flindersi: Fairly solid, acuminate, last whorl longer than the spire; colour: cream, blotched with light brown just below the sutures; sculpture of spiral lirae crossed by numerous, fine, axial plicae, which have each two small nodules arranged vertically, one at and one just below the suture; below the lower nodule is a narrow area in which the axial plicae are obsolete, there another nodule tops the longer plica of the whorls; plicae are somewhat cut by the axials but not sufficient to form distinct tuberculose sculpture; protoconch bulbous, of two smooth, turbinate whorls, set obliquely on the adult shell; adult whorls seven. Holotype, height 21 mm., diameter 8 mm.

Epidirona flindersi: The species is readily distinguished from others of the genus, the only one bearing the remotest resemblence is Epidirona striata Gray (= E. hedleyi Iredale), from New South Wales, which, however, has a coarser sculpture of a very different pattern.

Epidirona flindersi: South Australia. 80 miles west of Eucla, Great Australian Bight, 75 fathoms
