B69D63D67CEB5C0CB006DBFFE6CFFF02.taxon	description	Description. Of average shell length for the genus (76 - 87 mm; Table 1); shell pyriform to ovately pyriform, humped, with highest point towards posterior; W / L = 59.4 %, H / L = 48.3 %, and H / W = 81.3 %. Shell formula [82 (59 - 48 - 81) 20: 17]. Anterior and posterior extremities extended; anterior extremity rounded, supported by broad, thickened, lateral flanges; anterior tips rounded, not pointed; posterior terminal curved to left with right posterior tip extending further; dorsum smooth. Single anterior tubercule evident as small, raised callus on left side only; anterior groove absent; base convex, broad, flattened anteriorly. Aperture widening anteriorly, narrowest at anterior end of posterior canal; apertural teeth coarse, evenly spaced, and well developed along whole length and on both sides of the aperture; columellar teeth extending onto base. Labral teeth (28 - 35) more numerous than columellar teeth (22 - 30). Shell margins rounded, smooth; spire umbilicate; protoconch large (4.8 + / - 0.4 mm diameter; n = 6), projecting and prominent, positioned to the left so that the penultimate body whorl has greater exposure on the right side of the spire (Fig. 2 A, B). Fossula narrow, smooth, and slightly concave.	en	Southgate, Paul C., Militz, Thane A.
