Shell somewhat globose; axis 5 lines, diam. 4 lines. Spire exserted, short. Whorls inflated, rather square, sharply keeled round the inferior angle, minutely longitudinally striated. Colour dull olive, marked faintly with two or three broad bands of dark rufous-brown, which are very apparent in the aperture; columellar lip white, stained with a light dash of the same rufous-brown on the exterior margin. Hab. Streams in the Mahakeshwar Hills, Bombay Presidency. Mus. Cuming. }} In 1869, another English naturalist, William Thomas Blanford, moved this species to the newly created genus Cremnoconchus.[6] In the adult shell the last whorl is angulate below the suture and at the periphery.[6] The shell is imperforate, ovately conical, with the apex eroded.[6] The width of the shell is 5.5 mm.[6] The height of the shell is 8 mm.[6] ReferencesThis article incorporates public domain text from references[2][6] 1. ^Madhyastha A.
