). EMENDED DIAGNOSIS. — This fossil ziphiid genus differs from all the other known living and fossil ziphiids in: the mesorostral groove dorsally closed at the level of the antorbital noches by the joined medial margins of the premaxillary sac fossae, forming a prominent ridge posteriorly deviated on the left, and separating deeply concave anterior portions of the premaxillary sac fossae. It further differs from:
