Dear Harry,
For what it's worth, there's an image similar to the Rissoina tenuistriata on
http://shell.cable.nu/~seashell2392/Rissoidae1.htm
called R. inermis (Brazier, 1877). Is this a possible synonym?
David

>(1) Rissoina (Phosinella) tornatilis Gould, 1861. Matches lectotype
>(Johnson, 1964: 160; pl. 14, fig. 5; Higo, Callomon, and Goto 2001:
>G939). The species figured by Cernohorsky, Okutani, and by Chang and
>Wu is not the same.

>(3) Rissoina (Rissoina) tenuistriata Pease, 1868 See Cernohorsky

>of aperture and spire differ; holotype Johnson, 1964: 111; pl. 13, fig 7]
