Type specimen.

Syntype UMZC I. 102430 (1 shell; Fig. 5 E View Figure 5 after Preece et al. 2022: fig. 51 e) from Bengal.

Other material.

NHMUK (1 shell; Fig. 5 F View Figure 5 ) from Cherrapoonji (M 10604 / 2). NHMUK 20200349 (2 shells) from N. E. Bengal. NHMUK 20200350 (2 shells) M. 10695 / 2 from Khasi.

Diagnosis.

Shell oblong ovate and regularly attenuated; spire high conical; apex rounded; subsequent whorls with weak and irregularly spaced radial ridges, slightly stronger near suture, and fine radial groves present. Suture impressed and whorls slightly convex. Aperture ovate; columella strong, concave, and truncated.

Distribution.

This species is known from India and Rakhine State, Myanmar ( Godwin-Austen 1920).

Remarks.

The taxonomic history and clarification status of the type specimens have recently been published in Preece et al. (2022). Blanford (1865: 95) reported a small variety of Glessula crassilabris based on specimens from ‘ Arakan’ [Rakhine State] and ‘ Shan hills near Ava’ [Shan Hills near Innwa], and also suggested that the latter specimen lot were possibly distinct from G. crassilabris s. s., although they were closely related. The following year, Godwin-Austen (1920) introduced the Shan hills specimens as G. feddeni Godwin-Austen, 1920 , but the small variety from ‘ Arakan’ has never been made available.
