P. J. Lespérance and D. Desbiens 1995Encrinurines with subequal width: length glabellae and broader than long pygidia, variable tubercle size indices (6-15), significant genal spines, round middle hypostomal bodies with shallow rhynchos, 14-25 axial pygidial rings, 6-9 pleural ribs, and 1-3 congruent pleural ribs and axial rings.
D. K. Moss and S. R. Westrop 2014Librigena with precranidial lobe barely differentiated from anterior cephalic border, and with mostly granulose sculpture; anterior furrow obsolete (Fig. 6.8) or expressed only as reduction in density of sculpture (Fig. 6.5).
