INV 2014.101. 13.9 16.0 7.7 3.8 Remarks – This species probably belongs to the genus Cuneirhynchia on the basis of the planareas bordered by sharp ventral beak ridges; the slightly arched lateral commissures running close to the ventral beak ridges; the strongly deflected and nearly straight anterior commissure and the few (4 to 5), strong ribs, which appear only anteriorly. It stands close to C. palmata ( Oppel, 1861) , portrayed properly by OPPEL (1861, pl. XIII, fig. 2), UHLIG (1880, pl. V, fig. 4) and partly by GEYER (1889, pl. VI, figs 11, 13, 14), but differs from that by having fewer ribs (4-5, in contrast to 6-12 in C. palmata ) and by undulate anterior commissure in contrast to the sharp deflections of C. palmata . Therefore, this species is described here as a separate taxon and only the affinity indicated.
