Small, strongly biconvex, strongly transverse, with mucronate cardinal extremities, fold and sulcus narrow, noncostate and rounded, sulcus delimited by disproportionately large sulcus-bounding costae and fold by disproportionately deep and wide foldbounding interspaces, flanks with moderately numerous simple ribs that become smaller or indistinct laterally, growth lamellae becoming crowded and lamellose anteriorly, ventral interior with short, slender dental adminicula that follow margins of sulcus, dorsal interior with thick apical callus supporting cardinal process and long, platelike ridges that extend forward along inner crests of foldbounding grooves.
