Hesperiella Holzapfel, 1889 View in CoL

Australian Carboniferous species. Hesperiella elongata n.sp., from 'Rangari'; HesperieUa planorbis n.sp., from 'Marohn'; Hesperiella robertsi Yoo, 1988 , from 'Marohn'.

Remarks. The structure of the submerged protoconch of Hesperiella has been discussed by Knight (1941), Batten (1966) and Yoo (1988). It is almost certain that this genus has a hyperstrophically coiled dextral shell. Hesperiella has a narrow selenizone seen only in the final whorl. The slit is observed in the juvenile specimens (PI. 7 figs 10-12), although it is not obvious in the adult shells.
