[Meeks & Manger, 1999, p.147: Glaphyritids that are planorbid through four whorls. Immature suture for diameters <10mm
with very low medial saddle and very short prongs. Ventral lobe parallel sided to divergent, combined with a moderately
wide lateral lobe that is either rounded or pointed. Mature forms with small to moderate umbilicus (U/D =.25-.40), and
many become progressively evolute, conch subglobose to subdiscoidal (W/D =.30-.70), with compressed to depressed
whorls (H/W =.50- >1.0). Mature suture typically goniatitic with moderate to low median saddle, asymmetrical to slightly
asymmetrical prongs, and attentuate, broad to narrow lateral lobe. Constrictions common. Growth lirae crenulate to
noncrenulate. Umbilical region can be ornamented with one or more revolving ridges produced by liral crenulations.
Mature whorl shoulders tend to be angular].
