«Shell small, fragile, whitish, subcircular; convex (left) valve with small subequal ears finely concentrically lamellose; disk with extremely fine, close, radial threads with nearly equal interspaces; crossed by fine, concentric lamellae, with wider interspaces, more distant on the, beaks, closer toward the margin; interior glassy, the sculpture shining through; right valve similarly sculptured, except that the radial threads are obsolescent and the concentric lamellae more obvious; anterior ear longer with a wide byssal sulcus and fasciole, a single radial thread bordering the fasciole; margin of the disk flexible. Alt. 7.5; lat. 8.0; hinge line, 4.5; diam. 2.5 mm.
U. S. S. " Albatross," station 3392, Gulf of Panama, in 1270 fathoms, hard bottom, temperature, 36°.4 F. U. S. N. Mus. 122,869. A peculiar thing about the sculpture of this little shell is that, looked at in one light, only the radial, in another only the concentric sculpture is visible, and thus there is no effect of reticulation to speak of, yet there is little difference in the strength of the two kinds of sculpture.» WILLIAM HEALEY DALL, 1908

Remarks: Dall used the terms "white" or "whitish" in describing several species which are, like this, actually transparent. Unless the small deep-water shells of this famil)' are separated and washed, thorough study and accurate description are impossible. This species was previously recorded only from the type locality. Dr. Harald A. Rehder sent the author some unidentified Albatross material from the U.S. National Museum collection, and C. liriope was found to be present from station 2807, near the Galapagos Islands, in 812 fathoms.» GRAU, G. 1959.
