Original description: Shell, when viewed anteriorly or posteriorly, showing an elliptical to subangular cephalis without median constriction, and a nar-rower, open, distally tapering thorax. In side view, the shell is markedly compressed.
QTThe sagittal ring extends somewhat more than half the distance from the collar pores to the apex, and from its top arises an apical spine which is incorporated into the shell wall and then extends as a short thorn from the apical surface. Surface of lattice shell puckered at the level of the top of the sagittal ring. Primary and secondary lateral bars well developed.QTLattice shell robust, with pores of unequal size, subeircular on the cephalis and tending to be longitudinally elongated on the thorax. Vertical pore distinct. Termination of thorax uneven, with irregular lamellar teeth not markedly differentiated from the bars separating adjacent pores.
