---|---|---|
L. G. Hertlein 1925 (Pecten (Plagioctenium) calli) | Shell small, inequivalve. Right valve slightly arched, orna- mented by about 16 or 17 rather high, narrow, rounded, radi- ating ribs separated by interspaces of about the same width as the ribs; anterior ear with a large byssal notch and sculpture consisting of about five radiating riblets crossed by concentric lines of growth; posterior ear sculptured by radiating riblets crossed by concentric lines of growth. Left valve slightly prolonged posteriorly, much more highly arched than right, and sloping rather abruptly from the umbos, sculptured by about 19 well developed, rather sharp, rounded, radiating ribs separated by interspaces about as wide as the ribs, ribs and in- terspaces crossed by fine concentric lines ; ears slightly concave, the anterior with a small notch and ornamentation consisting of five or six radiating riblets crossed by concentric lines of growth; posterior ear slightly prolonged at the hinge line, sculptured as right. Altitude 24 mm. ; longitude 24 mm. ; diameter of left valve approximately 7 mm. ; apical angle ap- proximately 90°. |
