Acc. to Dall & Bartsch: Shell 2.3 x 1.1 mm, n + 6w (n.w. decollated); 3 spiral cords; white with 3 bands of dark brown, the first extends over the posterior row of tubercles, the second covers the cord at the periphery while the third extends over the anterior half of the base. Anterior half of the base marked by 10 raised spiral threads. 2 specimens Bermuda.

Shell elongate-ovate, white, with three bands of very dark brown. The first of these bands extends over the posterior row of tubercles on each whorl, the second covers the cord at the periphery, while the third extends over the anterior half of the base. Nuclear whorls decollated in the two specimens before us. Post-nuclear whorls marked with three spiral cords, of which the first is at the summit, the third at the suture, while the second is a little nearer to the first than to the third. In addition to these spiral cords, the whorls are marked with somewhat retractive axial ribs, which are about as strong as the spiral cords, the intersections of the two forming well developed tubercles, while the spaces inclosed between them are strongly im-pressed, rounded pits. The tubercles of the cord at the summit are well rounded; those of the median cord slope abruptly anteriorly and more gently posteriorly, while those of the third cord are trun¬cated posteriorly, sloping gently anteriorly. Sutures strongly impressed. Periphery of the last whorl marked by a spiral cord, which is less strong than those on the spire. Base moderately long, well rounded, the posterior half marked by the continuations of the axial ribs, which terminate somewhat abruptly at the insertion of the columella. These ribs render the peripheral spiral cord tuberculated, the tubercles being slightly truncated posteriorly, sloping gently anteriorly, where they disappear at the insertion of the columella. The insertion of the columella is marked by a moderately strongly impressed, spiral line. Anterior half of base marked by ten somewhat irregular, raised, spiral threads, which are about as wide as the spaces that separate them, the entire space being marked with exceedingly fine, raised, axial threads. Aperture irregularly rhomboid, decidedly channeled anteriorly, weakly channeled at the pos¬terior angle; outer lip thick, showing the external sculpture and color markings within; inner lip reflected over the base; parietal wall covered with a thick callus which joins the columella and the posterior angle of the aperture and renders the peritreme complete.
Two specimens of this species were sent by Mr. Haycock, which may be considered cotypes. One of these is in the Bermuda Museum, the other is Cat. No. 221G15, U.S.N.M. One of these has six post-nuclear whorls and measures: Length 2.3 mm., diameter 1.1 mm.
