«Description: Shell inequilateral, slightly produced posteriorly, weakly inflated; valves equally convex; right anterior ear deeply notched, sculptured with 6 to 7 strong radials, right posterior ear with 5 radials of moderate strength; left anterior ear with 5 weak radials, left posterior ear with 7 strong radials; disk with 21 to 24 narrow unilirate ribs and slightly narrower U-shaped or flat-bottomed interspaces, and with fine concentric lamellae.
Discussion: The simple unicarate ribs, the general shell outline, and the convexity of this species is similar to that of Chlamys (Aequipecten) nupera (Conrad) of the Jackson Group. It differs from the latter species in having interspaces that are U-shaped or flat-bottomed rather than V-shaped and in having a thinner shell. One specimen from locality 93 has fine intercalary ribs. Though the type and the better preserved specimens of this species are from the Byram Formation, it is most abundant in the Forest Hill Formation at locality 75a.
Type: Holotype 340434 USNM from the Byram Formation, locality 112c (Plate 11, figure 1).
Occurrence: Mississippi: Forest Hill Formation, locality 75a; Byram Formation localities 93, 112c.»
