Eucithara harpellina

The length of the shell attains 8 mm, its diameter 4 mm. The shell has an oval subfusiform shape, with a short turriculate and acuminate spire. The crystalline white shell is opaque and matt on the ribs, hyaline shining on the decurring cords. The whorls are tinted with a tan yellow colour, more or less interrupted at the interstices. The last brown bands are usually reduced to enlarged spots on the ridge of the ribs, and are sometimes accompanied by a fifth zone. In the dorsal part, the colouring of the strips becomes darker with a tendency to widen and produce on the penultimate rib a large brown spot. The shell Is decorated with longitudinal ribs, 10 on the body whorl. These are moderately thick and very high. They mark on the upper whorls a space equal to their thickness, which widens at the back of the body whorl. From the suture on, above which they rise, the less prominent ribs descend obliquely flexuously towards the siphonal canal, where they form a cluster of concentric arcs. Cords, somewhat high, narrow and pressed together, run transversely across the whole shell by crossing the ribs. These shiny cords alternate with translucent and matte intervals and offer a graceful effect. They appear under a lens as a very fine lattice, produced by the growth lines. The spire consists of 6 to 7 whorls, including 1½ whorls in the protoconch. …
