Type locality.

“Torúpútú Peak, 7000 feet".

Material examined.

Toruputu Peak, Dafla Hills, coll. Godwin-Austen, NHMUK 1903.7.1.2497 (lectotype: here designated, and 6 paralectotypes). The type sample contained two vials, one with two and the other with four shells. The one with four shells contained three larger shells and one which was conspicuously smaller. That smaller shell differs from the larger ones in terms of other shell characters, such as the spire height (lower than the others), the sculpture of R1 (smoother than the others), the strength of the swelling on R3 (less elevated than that of the others), and the lobes of the peristome (less conspicuous than those of the others). Therefore, one of the larger shells is selected here as lectotype to avoid further confusion.

Remarks.

Protoconch low, rather matte, no spiral lines visible; R1 irregularly, finely, densely ribbed, some spiral lines visible but these are probably part of the layer below the outermost one; R2 relatively short, smooth, only lighter, narrow and slightly thicker, darker stripes alternating.
