==Description==
The length of the shell varies between 20 mm and 27 mm. The conical, elevated-trochiform shell is solid and imperforate. The first whorls are red, the following reddish-brown, more or less tinged with buff, and in places with olive-green, and sparsely maculate with whitish. The spiral ribs are more or less articulated minutely with whitish. The 8 to 9 whorls are flat or a trifle concave, and acutely carinated. The carina projects a trifle above the sutures. The upper surface of each whorl is encircled by 10 to 12 spiral lirae, only slightly elevated, and showing strong, regular oblique striae of increment in the interliral interstices. The base of the shell is flat, with about 10 concentric narrow lirae, that are strongly, regularly radiately striate. The rhomboidal aperture is very oblique, iridescent and sulcate within. The outer and basal lips are edged with green, and plicate-denticulate within. The green, curved columella ends in a strong tooth at its base. 〔 (Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia ) 〕
