Type material examined. Myanmar • Syntypes. NHMUK 1903.7.1.2201 (2 shells; Fig. 16 C) from Moulmein, Tenasserim (figured in Godwin-Austen 1884: pl. 49, figs 7, 7 a); Godwin-Austen coll. Diagnosis. Shell tiny, dextral, pupate-fusiform, translucent, pale yellowish to whitish. Whorls ~ 6, slightly shouldered to rounded; spire ovate-conical; suture deep. Teleoconch with equally spaced, strong radial ribs throughout. Spiral striations thin and appearing throughout. Last three whorls nearly equal in width; penultimate whorl slightly less inflated than others. Aperture ovate; columellaris weak, not prominent. Peristome expanded; lip slightly thickened, multi-layered. Umbilicus closed. Distribution. This species was previously known only from its type locality in Mawlamyine, Mon State, Myanmar (Godwin-Austen 1886; Gude 1921). Remarks. The name edentula was first introduced by Godwin-Austen (1884) in ‘ Land and Freshwater Mollusca of India’; however, it was published without a description, definition, or indication, as only shell illustrations and the collection locality were provided. Accordingly, the name does not meet the criteria of availability under the ICZN (1999: Art. 12.2) and was therefore unavailable in Godwin-Austen (1884). Subsequently, in the same series, Godwin-Austen (1886) published a full description of the taxon under the same name, thereby rendering edentula an available name from that publication.
