: Shell depressed, white, with dark reddish-brown, scattered flammulations on the apical surface and shell base. Shell thin, opaque; periostracum adherent, matt. Apex barely raised, spire elevated, later whorls descending more rapidly. Apical and umbilical sutures impressed; whorls and periphery rounded. Transition between protoconch and teleoconch indistinct. Protoconch sculptured by very fine spiral and axial lirae, forming a reticulated pattern; spiral lirae fading on the transitional zone between protoconch and teleoconch. Axial lirae progressively transitioning into coarse ribs, with interspaces two to four times their width, comprising the primary sculpture of the teleoconch. Secondary sculpture of the teleoconch formed by crowded, wavy axial riblets, with interspaces approximately equal to their width, overlaying the primary sculpture. Umbilicus very narrow, deep. Peristome crescent-shaped; columellar lip reflected towards the shell axis, constricting the umbilicus in part. Palatal wall with four barriers and three traces, all recessed, extending approximately one-eighth whorl, with gradual anterior and posterior descension; all traces deeply recessed; first trace columellar in position, second and third traces infraperipheral and peripheral in position; barriers regularly spaced, similar in prominence, progressively transitioning from very shallowly recessed (first) to deeply recessed (fourth barrier); first barrier positioned at the confluence of basal and columellar lips; second and third barriers mid-basal in position; fourth barrier positioned at the confluence of basal and peripheral walls, as deeply recessed as traces. Parietal barriers five in number, not recessed within aperture, extending approximately one-quarter whorl, regularly spaced, with gradual anterior and somewhat abrupt posterior descension; barriers one to four similar in morphology; fifth barrier lower than the remainder. Other shell features that can be expressed numerically are shown in
