Shell elongate-ovate, pale buff, with a brownish flush, marked by in- 

 terrupted spiral bands of pale brown whose elements are also arranged 

 in axial series. These bands are present on both spire and base. Nuclear 

 whorls 2, well rounded, forming a small apex, which is somewhat flat- 

 tened at the tip. Postnuclear whorls well rounded and marked by retrac- 

 tively curved, rather low, closely spaced axial ribs, of which 169 occur 

 on the last turn. These axial ribs are separated by mere impressed lines. 

 The spiral sculpture consists of low, rounded, rather broad cords, of 

 which 16 are present between the summit and the periphery. The junc- 

 tions of the axial ribs and the spiral cords form low, weak nodules. 

 Suture rendered conspicuous by the slightly tabulated shoulder. Periph- 

 ery well rounded. Base rather short, inflated, strongly rounded, openly 

 umbilicated and marked by the continuation of the axial ribs and 14 

 spiral cords, which equal those on the spire in strength. The umbilical 

 wall has also a feeble continuation of the axial ribs and 11 spiral threads, 

 which are much stronger here than on the spire. The last whorl is usu- 

 ally separated from the preceding turn by a mere slit; sometimes, how- 

 ever, it may be adnate. Aperture oval ; peristome double, the outer 

 moderately broadly flaringly expanded, a little narrower on the parietal 

 wall than on the rest, forming a moderately strong auricle at the pos- 

 terior angle, and marked by concentric lines of growth; the imier moder- 

 ately exserted and reflected. Operculum typically licinid.

 fore, is a topotype. It has 4.5 whorls remaining and measures : Height,
