Type specimen.

Syntype NHMUK 1888.12. 4.1081 (1 shell; Fig. 12 F View Figure 12 ) ex. Theobald collection from Shan States, Burma.

Diagnosis.

Shell slender, elongate turreted and rapidly attenuated; apex obtuse; subsequent whorls coarse with dense growth lines throughout. Suture wide and shallow, and whorls slightly convex. Aperture elongate ovate and narrow; columella curved; peristome little acute.

Distribution.

This species is only known from the type locality.

Remarks.

No recent material of this species was collected in this survey, and the syntype is illustrated here for the first time. Gude (1914) recognised this species as belonging to the Prosopeas , but Naggs (1994) provisionally transferred this species to the Paropeas after comparing it with the type specimen.

Paropeas terebralis can be distinguished from P. swettenhami by its broader and more rounded embryonic whorls, deeper suture and slightly convex whorls, and coarse shell surface with dense growth lines. Whereas P. swettenhami possesses narrower and pointed embryonic whorls, shallower suture and flattened whorls, and shell surface with dense and fine radial striae.
