Type locality.

"que dans les grottes formées dans l’intérieur des montagnes de marbre qui s’élèvent au milieu de la plaine oú est bâtie la ville de Turanne, en Cochinchine".

Material examined.

Annam, Touranne, leg. Frühstorfer, coll. Möllendorff, SMF 109290 (5 shells); Same data, NHMW 43182 (4 shells); Cochinchina, coll. V.W. MacAndrew, NHMUK.

Remarks.

Protoconch matte, without spiral lines; R1 fine, dense, rather regular ribs with weak spiral striation; R2 long, with dense, lamellae-like, elevated ribs, which are most elevated closer to the suture. Below the ribs, the microtunnels are visible as narrow light bands between the darker, thicker stripes (visible where there are weathered areas of the shell).

Habe (1965) reported " Dioryx gibbus (Reeve)" from "Kao Phlong, north or Sara Buri, Central Thailand", without publishing a picture. This almost certainly refers to a different species.
