Type material.

Lectotype HMT 229 a (Figs 5 C View Figure 5 , 12 C View Figure 12 ), designated herein ; 33 paralectotypes HMT 229 b, paralectotype USNM 472304 About USNM , nine paralectotypes MCZ 167034 About MCZ .

Type locality.

“ Tchen-K’eou ” [Chengkou, Chongqing City].

Brief description.

Shell dextral, with about 6 whorls. Protoconch smooth. Penultimate whorl slightly expanded, body whorls nearly as wide. Constriction at slightly right of parietal wall. No spiral striation visible. Teleoconch with thin, widely spaced, radial ribs, ca. 7 ribs per 0.5 mm on penultimate whorl, ca. 5 ribs per 0.5 mm on body whorl. Dorsal fold absent. Umbilicus closed. Double lip present. Columellar tooth present. One short horizontal palatalis just above columella. One vertical palatalis.

Remarks.

The lectotype is designated herein in accordance with Art. 74 of the Code ( ICZN 1999) for the stabilisation of the name. Johnson (1973) listed ‘ paratypes’ housed in USNM and MZC. Kobelt and Möllendorff (1898) assigned this species to the subgenus Sinica . For HMT specimens, 33 specimens moved to D. (S.) setchuanensis by Dr. C. - C. Hwang, one specimen has been separated by Dr. C. - C. Hwang as form A (Figs 5 D View Figure 5 , 12 D View Figure 12 ), another specimen as form B (Figs 5 E View Figure 5 , 12 E View Figure 12 ). Both forms alleged to be distinct from D. confusa .
