Description

as Rictocyma mirabilis Dall, 1872
Shell small, subtrigonal, olivaceus, moderately thick. Umbones nearly erect, prominent, pointed : exterior covered with a thick olive-green epidermis lightly marked with concentric lines of growth. Interior livid translucent greenish, smooth. Hinge as in Astarte but more equilateral than in most species of that group. Anterior margin more produced than the posterior, while the contrary is the case in the majority of species of Astarte. Sculpture similar in both valves, consisting of eight or nine ridges, arranged in a generally concentric manner, but having a squarish fluctuation in the middle of the valve toward the umbo, one on each side of this toward the margin, and recurved more or less toward the anterior and posterior margins. These ridges are broken and non-continuous toward the sides and are rudely nodulous toward their extremities, which do not reach the anterior and posterior margins in most cases.
Alt. 0,12, lon. 0,16, Diam. 0,04 inch.
Habitat, North Harbor, Unga Island of the Shumagin group, in 8 fathoms, muddy bottom, one living specimen, September, 1865, Dall.
