A specimen retaining both valves : a riglit valve (from Hall). from posterior to the beak, to the post-inferior margin, where it causes a slight constriction in the margin; very fine con- centric strife, often crowded on the posterior portion of the sheU. Found in the lower Moscow shale, at Sections 4 and 5 ; in the Lower shale, down to and in the shale below the Trilobite beds, at Sections 5 to 8; and in the Strophalosia bed. on the Lake Shore (where it is very rare).
