Conch. VII., 1872, p. 20. 
This species has the apertural charactezs proper to Rissolina, 
and is, therefore, removed thereto from Schwartziella. 
The types of R. flexuosa and R. turricula are both from New 
South Wales. Tryon states the origin of the synonyms, p. 381, 
op. cit., as follows: —‘“‘ Gould’s description was made from an 
immature specimen; Angas subsequently described it as R. 
turricula, which being pre-occupied by Pease, the latter changed 
it to R. Angasi.” Reeve treats them as distinct species. 
The identification of South Australian examples with 2&. 
turricula was in the first instance due to Angas, from material 
forwarded by me. | 
Distribution —New South Wales (types). In South Australia 
it has the same range as F#. crassa. I have identified examples 
from West Australia, Victoria, and Tasmania (previously recorded 
by Tenison-Woods). |
