«PECTEN (LYROPECTEN) EULYRATUS, sp. nov. Plate 14, figure 28.
Shell small, subcircular, thin, compressed; auricles broad, unequal, byssal notch moderately large, with six teeth in the ctenolium; sculpture consisting of fifteen raised, somewhat squarish ribs on the upper valve; two or three radial threads in the interstices, and concentrically sculptured by very fine lines of growth; auricles with five or six radial striae; lower valve with sixteen squarish, elevated ribs, interstices a trifle smaller than the ribs; concentric sculpture of fine growth lines; auricles with about five rather broad radial riblets, finely squamose, crossed by lines of growth. Color dirty white, yellowish at the umbones and on the auricles, marked by zigzag lines and flecks of opaque, snowy white, and scattered fawn colored flecks; under valve obscurely but similarly marked. Alt. 20.5 mm., lat. 20.0 mm., diam. 5.0 mm., hinge line 15.0 mm. Taken from Biscayne Bay (Dade County), Florida, by Mr. W. A. Royce, who probably has done more intensive collecting in this rich field than any other collector. The type is in his cabinet. This shell may be distinguished from the allied Lyropecten antillarum Récluz by its greater number of narrower, higher ribs, and somewhat greater compression.» FREDERICK MERKLE BAYER, 1943
