The holotype of 'G.' baum- bergeri is a fully grown specimen (55 mm diameter) with a three- quarters whorl long probably complete body chamber and ap- proximated last few septa. The internal mold of the venter at 30 mm D is narrowly tabulate-carinate and was probably tricarinate on the shell. The simple septal suture is poorly preserved. The weak costation of the nucleus is fascicidate and somewhat irregidarly tuberculate; on the intermediate whorls, the costae withdraw from the umbilical seam and become obsolescent on the relatively small body chamber. The septal sutme drawn by Krvuzinga (p. 40) is probably 'simplified' due to corrosion. The holotype of 'G.' kiliani, also an internal mold, is still incomplete at a diameter of approxi-.
