Glaphyrites RUZHENCEV, 1936, p.484, type species: Gastrioceras modestum Boese, 1919, p.83; OD [= Ambiguites SMITH, 1938, type A. gargantuus, p.29; OD (subj.)].

A: Conch form globular to thick-discoidal, more or less involute, ventral side broadly rounded. Moderately evolute on inner whorls, but no extended ophioconic stage,later with moderately wide or narrow umbilicus.

B: Growth lines on young stages usually with ventral salient, at maturity with broad sinus. Umbilical shoulder of immature whorls may be slightly nodose, commonly with multiple spiral threads or simple transverse lamellae.

G: Ventral lobe fairly wide, height of median saddle about or exceeding half the height of entire ventral lobe. First lateral
saddle broadly rounded, adventitious lobe deep, relatively wide and bell-shaped. [Ambiguites has been based on one rather
large specimen with narrowly rounded, almost acute venter, which does not show form and sculpture of inner whorls;
the type species is probably conspecific with G. subdiscus (UNKLESBAY 1962)].
