Bulimus plicifer Blanford, 1865: 77. Type locality: Thayet Myo, Pegu. Pfeiffer 1868: 151. Hanley and Theobald 1874: 34, pl. 80, fig. 8.
Bulimina (Hapalus) plicifera — Pfeiffer and Clessin 1881: 300.
Buliminus (?) plicifer — Kobelt 1901: 688, 689, pl. 103, fig. 22.

Type specimens.
Syntypes NHMUK 1906.2. 2.235 (2 shells; Fig. 4 A) ex. Blanford collection from Thyetmyo, Pegu? Akouktoung.
Diagnosis.
Shell ovate conic; spire low; apex bluntly obtuse; subsequent whorls with prominent growth lines throughout. Suture shallow and whorls flattened. Aperture broadly ovate and somewhat pointed posteriorly; columella straight and expanded; parietal callus thin and with small parietal lamella. Umbilicus narrow.
Distribution.
This species is restricted to Myanmar and is known only from the type locality.
Remarks.
No new material of this species was found in this study, and only the available syntypes are examined here. The modern name of the type locality is Thayet District, Magway Region, central Myanmar [not in the Bago Region].
Among the four Curvella species from Myanmar, this species is similar to C. pusilla (Blanford, 1865) in shell shape. However, C. plicifera has a small parietal tooth, straight columella, and narrowly opened umbilicus, whereas C. pusilla possesses a smooth parietal wall (without tooth), slightly twisted columella plait, and closed umbilicus. Further confirmation from additional specimens is necessary to verify their distinctions.
