Type specimen.
Possible syntypes NHMUK 1906.2. 2.239 (7 shells; Fig. 15 A, B View Figure 15 ) ex. Blanford collection from Henzada, Pegu and Tongoop , Arakan .
Other material.
NHMUK 1888.12. 4.1229–31 (3 shells; Fig. 15 D, E View Figure 15 ) from Pegu. NHMUK 20230921 (5 shells) from Tongoop, Arakan (Fig. 15 C View Figure 15 ).
Diagnosis.
Shell slender, elongate turreted, and rapidly attenuated near apical whorls; apex rounded; subsequent whorls nearly smooth, fine growth lines, and with equally spaced ridges near suture. Suture impressed and whorls slightly convex. Aperture ovate; columella concave and truncated.
Distribution.
This species was reported from several places in Myanmar: Henzada [Hinthada City, Ayeyarwady Region], Thayet Myo [Thayet City, Thayet District, Magway Region], Pegu [Bago Region], and Tongoop, Arakan [Taungup Township, Thandwe District, Rakhine State] ( Nevill 1878; Gude 1914). It was also reported from Meghalaya State, India ( Ramakrishna et al. 2010).
Remarks.
The original description does not clearly state how many specimens were available to the author, although only one set of measurements was given. The NHMUK collection contains a lot of seven specimens from the Blanford collection with this species name. However, this is a mixed specimen lot of the same species as it consists of two collection localities, ‘ Henzada, Pegu’ and ‘ Tongoop, Arakan’, where only the latter was mentioned in the original description as the type locality. Therefore, this specimen lot NHMUK 1906.2. 2.239 is considered as possible syntypes, from which two specimens are illustrated herein.
