scale bar is 4 mm
Like Isorophus and Curvitriordo, Carneyella has relatively long and curved ambulacra, one of which is curved clockwise. Carneyella is distinguished by the presence of a single series of ambulacral coverplates on either side of each ambulacra, rather than two as in Isorophus, or three as in Curvitriordo.
