«Shell thin, ashy white externally, internally semi-nacreous; rounded with a comparatively short straight hinge-line; attached valve unknown; upper valve indistinctly auriculate, rather flat, irregular toward the margin with a small pointed but not prominent apex, a little to the right of the middle of the hingeline; sculpture composed of somewhat irregular radiating costae, not bifurcating but increasing by intercalation toward the margin, where they are much crowded; these costae are formed by crowded overlapping rounded scales, like biscuit piled one over another, and showing sharp edges only where worn; there are about forty with a somewhat smaller number of intercalary ones; the concentric sculpture is composed of ill-defined lines of growth, and the whole surface is microscopically granulose; interior polished, silvery, reproducing the external rugulosities; muscular impressions in\isible; cartilage pit triangular, distinct, hinge-line smooth, margin nearly simple. Lon. of shell, 28.0; of hinge-line, 13.0; height of shell, 30.0 mm.
Station. 227, off St. Vincent, in 573 fms., fine sand and gray ooze; the bottom temperature 40°.5 Fahrenheit. This shell has an unmistakably abyssal facies and seems to belong to the genus Hinnites. It is named in honor of Prof. Charles B. Adams, of Amherst, to whom so much of our knowledge of the fauna of the West Indies and Panama is due, and who was among the first of American naturalists to recognize the variability of what we call species, and the close relations which exist in nature between forms admitted by naturalists to be of "specific" value, or, in other words, which have obtained a temporary equilibrium of characters which they transmit to their descendants.» WILLIAM HEALEY DALL, 1886

«Hinnites adamsi DaII, 1886, may turn out to be closely related to P. levii. It has been recorded only once, from St. Vincent, West Indies, at a depth of 1050 m. The morphology is unknown. Dijkstra (1989) proposed that Pecten fluctuatus Bavay, 1904, from the Andaman Sea (depth unknown), could be a third representative of Pseudohinnites. It is known only from the type specimen in the Zoological Survey of India, New Alipore, Calcutta. A recent examination ol this specimen by the first author shows it to be in very poor condition and, rather, a representative of Delectopecten.»

«Remarks. — The only other species in the genus Pseudohinnites is Pseudohinnites adamsi (Dall, 1886) from off St. Vincent (West Indies) at 1031 m (573 fms.), represented by one left valve only and described as Hinnites adamsi (Dall, 1886: 223, pi. 5 fig. 6). It is very close to Pseudohinnites levii. Another left valve was dredged by the Dana Expedition, south of the Virgin Islands (Dana sta. 1275, 17°41.5'N, 64°55'W, 550 m, 28.V. 1922), and is housed in the Zoological Museum, Copenhagen (ZMK). No right valves have yet been taken.»
