Shell elongated-oval. depressed. Front slope long, convex, side slopes slightly convex, posterior slope concave. Apex compressed, with one whorl at the right side, placed at about 4/5 of the total length. Colour yellowish-white; sculpture consisting of about 44 radiating ribs, and a few intermediate ones at irregular intervals, and one or two very fine, radiating threads in each interstice, the whole shell is crossed by fine concentric ridges, forming on the ribs conspicuous compressed scales. Slit-fasciole rather large, elevated, forming a strong rib or keel on the front slope, with close-set, strong, curved lamellae. Margin crenulated by the ribs, raised at the sides, the shell resting on its ends; slit long. 2,75 mm., broad 0,6 mm., its margin slightly thickened, a strong groove runs towards the deeply pitted apex. Interior white, smooth, apparently cancellated, in consequence of the transparency of the shell. Long. 9,5 mm., lat. 6,5 mm., alt. 3 mm.

Resembling in shape Emarginula harmilensis Sturany (Exp. S. M. Schiff "Pola" in das Rothe Meer, Gastropoden) but differing in colour, that species being-variegated by spots, lines and points of a brownish to greenish colour, the apex is placed still nearer to the posterior end, and the ribs are not scaled, but only beaded.
