Additional material. 30 additional specimens of G. obesum Y00, 1988 were recovered from the type locality and east of Glenbawn Dam (Locality 30) .

Remarks. The figllred specimens (PI. 6 figs 6, 9, 10) appear to be immature. The specimens (PI. 6 figs 4, 5) have straight whorl profiles with smaller pleural angle, coarser ornamentation and smaller umbilicus, which appears to be relatively mature. This species differs from Glabrocingulum ornatum (Dun & Benson) in having smaller and low-spired shell.
