Shell elevated, conical, with oval base and curved apex. Front slope convex, posterior slope concave, side slopes convex below, concave towards the apex, which is slightly bent towards the left and shows scarcely one spiral whorl on the right side. Colour yellowish. Sculpture consisting of numerous, radiating riblets, which are alternately stronger, the intermediate weaker ones don't reach the summit but end at about 2/3 of the height, they are surmounted by rounded-triangular or pear-shaped beads, the interstices are rather irregularly concentrically wrinkled; orifice oval, lying just before the apex, slightly narrower above, its length is about 1 mm., its breadth a little more than 0,5 mm. Interior white, smooth; septum large, nearly straight, only slightly curved, directed towards the front-side, apparently slightly incised in the centre (this is not certain, the margin not being quite intact): a thin slitcallus seems to exist. Long. 6 mm, lat. 5 mm, alt. 3,5 mm.

This interesting species will be easily distinguished by its beaded sculpture, I find in littérature only Puncturella agger Wats. (Challenger Gastrop. p. 40, PI. 4, fig. 6) which has a similar, but still different sculpture, and may be distinguished by its shape, slit, septum, etc.
