Pecten (Chlamys) liocymatus n. sp.
«Shell (right valve) small, oblique, moderately convex, with about 20 low rounded entire ribs with narrower shallow interspaces; the surface somewhat worn, is smooth except for concentric lines of growth which may originally have been more prominent; profile subcircular, the ears small, subequal, with a few radiating threads on the anterior ear; the byssal notch shallow; the interior partly grooved in harmony with the external ribs, the edges of the flat interspaces threaded; hinge line straight, in the right valve with a groove each side of the resilifer to receive a corresponding ridge from the opposite valve, these grooves are sharply cross-striated; height, 30; width of shell, 28; of hinge line, 16; diameter (of right valve), 5 mm. U. S. Nat. Mus. Cat. No. 62290.
Dredged by the U. S. Fish Commission steamer Albatross at station 2604, in 34 fathoms, sand, bottom temperature 79º F., 39 miles off Cape Hatteras, North Carolina; two right valves. These specimens, perhaps originally white, have been discolored by the action of the sea water. I have not been able to find any species recent or fossil which is at all closely related to this one». WILLIAM HEALEY DALL, 1925
