Diagnosis
ReferenceDiagnosis
L. G. Hertlein 1925Shell moderately arched, coarse and thick, slightly longer than high. Right valve ornamented by about 23 or 24 rounded to slightly flat-topped ribs, separated by narrower, round-bot- tomed interspaces, both the interspaces and ribs crossed by concentric incremental lines, and, in some cases, by rather strong lines of growth ; anterior ear with a large byssal notch, and sculpture consisting of about five or six radiating riblets, crossed by concentric incremental lines ; anterior and posterior margins of valves smooth except for concentric incremental lines ; ventral margin rounded ; posterior ear ornamented by about eight radiating riblets and by lines of growth, the posterior edge of the ear forming nearly a right angle with the hinge line. Left valve convex, higher at the umbo than the right valve, and ornamented by about 24 or 25 squarish, flat- topped, rounded ribs, separated by narrower, round-bottomed interspaces, the whole valve sculptured by concentric lines of growth ; ears slightly concave, ornamented by about six or seven radiating riblets. Altitude 90 mm., longitude 95 mm. ; diameter of right valve approximately 15 mm. ; apical angle of right valve approximately 114°.
