Description "Large, robust. Elongate, sub-rectangular to sub-ovate. Anterior broadly rounded, asymmetrically so in LV extremity below mid-height. Posterior caudate, more so in RV. Both margins denticulate. Dorsal margin straight to gently convex. Reticulum well-developed. Muri somewhat irregularly distributed over valve surface; bold, sharp and of high relief with the exception of the posterior fifth where they "becomes low and subdued. Ventro-Iateral and dorsal ridge prominent, non-spinose. Bridge modified; muri raised and thickened, forming a prominent, circular mural structure enclosing the frontal muscle scar area. A weak and irregular median ridge extends posteriorly from this structure, disrupting the median loop and causing the adductor muscle scars to be enclosed within a similar, but larger, circular mural framework. Foveolate. Normal pore canals and inner lamella details as for genus; radial pore canals tending to be grouped in pairs. Hinge holamphidont, posterior terminal tooth of RV slightly arcuate and nonlobate." (Whatley, Downing, Kesler & Harlow, 1984: 281) [details]
Diagnosis “An elongate and caudate species of Bradleya with a bold reticulum; muri sharp and of high relief. Bridge modified into a prominent, circular mural structure completely enclosing the frontal muscle scar area. Weak median ridge disrupting the vertical median loop. Ridges lacking spines." (Whatley, Downing, Kesler & Harlow, 1984: 281) [details]
