Left valve small, moderately inflated, suborbicular, subequilateral; radial sculpture consisting of 17 or 18 narrow, square ribs separated by deeply channeled interspaces slightly wider than ribs; concentric sculpture consisting of widely spaced lamellae overrriding radials except the umbo; auricles subequal, sculptured with 4 or 5 radial ribs overridden by concentric lamellae; right valve not known. Left valve: length 8 mm.; height 8 mm.; diameter 1.4 mm.; length of hinge 6 mm. C. mansfieldi is represented by few valves, probably none of wich is full grown.
