Whorls moderately low, height on teleoconch whorl 16 corresponding to approximately 45 % the width. Suture narrow, distinct, but not deep. Keel sharp, located at transition to base at abapical suture line. Base flat with short anterior canal. Last whorl on large specimens may increase dramatically in width, becoming more convex with the keel changing to a more central location on the whorl before disappearing just behind aperture. Aperture rounded subrectangular with smooth, slightly concave columella. Teleoconch strongly sculptured adapically, becoming smoother abapically with only weak spiral ribs on base of inflated final whorl. First whorl with five to six strong transverse ribs on a half whorl, crossed by two weaker spiral ribs, forming two weak tubercles on transverse ribs. A third, narrower adapical spiral rib is added on third whorl. Spiral ribs increase rapidly in number while becoming finer. Transverse ribs may increase slowly or faster in number abapically, while tubercles become more pronounced, arranged in up to four rows. Keel carrying narrow spiral rib, which may be slightly serrated due to densely spaced growth lines. Base with single primary spiral rib slightly adaxially of keel rib and succeeded by closely spaced, weaker secondary spirals. Growth lines closely and evenly spaced, nearly straight adapically of keel, weakly opisthocyrt.</paragraph>
