Description

Shell decollate and with the aperture imperfect, having evidently the general form of Eubela limacina, but with a slightly more differentiated canal; surface smooth, polished, with a distinct suture in front of which the fasciole appears as a narrow raised band, with an incised line in front of it and marking its edge; the only other sculpture consists of six or seven sharply incised lines on the canal near its anterior end; whorls and base full and rounded; incremental lines visible but faint; color yellowish white with about ten spiral bands of alternate whitish and reddish brown rectangles on the last whorl arranged like the squares on a checkerboard, except that, the white rectangles being longer than the brown ones and the latter being symmetrically arranged, the angles of the brown rectangles in one line do not generally connect with those of the lines in front and behind it; on the curve of the base the rec¬tangles are drawn somewhat lozenge-shaped. Long. of the last whorl, 3.75 mm; Lat. of same, 2.75 mm.
First description: Dall, 1889.
