Agnesia de Koninck, 1883 View in CoL

Australian Carboniferous species. Agnesia reticulata n.sp., from Swains Gully.

Remarks. This is the first record of Agnesia in Australia. Agnesiaresembles Hesperiella in having a sinistrally coiled shell, with an inturned protoconch, and moderately wide umbilicus, but differs in having a reticulate ornamentation and the narrow, deep peculiar selenizone. The protoconch of Agnesia has not yet been observed, but because of the inward coiling, as seen in HesperieUa , it is assumed that Agnesia has a hyperstrophically coiled dextral shell.
