) bulbous, with pitted, irregular surface, not too prominent; transition visible as thin orthocline line. Teleoconch of circa 4 whorls, with well-marked, but not particularly deep suture. Outline concave between cords, but with an overall convex profile; region slightly below suture markedly concave; sculpture consisting of delicate but well-marked spiral cordlets crossed by axial threads, forming a delicate reticulate pattern; disposition of axial threads alternating between prosocline, orthocline and opisthocline between cords along the shells longitudinal axis, constituting an overall continuous sigmoid pattern; spiral sculpture becoming gradually weaker toward basal region of last whorl. Body whorl base sculptured by 1012 spiral cords, with axial threads also present between cords. Umbilical region smooth, edge rounded but thick and well-marked. Aperture quadrangular, height 1/2 shell height, with three labral sinuses: a deep, large (1/5 of whorl height) subsutural sinus; a small (1/6 of aperture height), very shallow sinus in medial region of outer lip; and a relatively large (nearly same size as subsutural) sinus on basal region of aperture, congruent with umbilical carina. Umbilicus narrow (diameter 1/7 of shell diameter), deep.
