curving to the basal lip; basal lip with a large tooth-like incrassa- 
tion near to its junction with the columella. p 
Umbilical callus small, granulated. Operculum unknown. 
Major diameter, 4; minor diameter, 3:5; height, 2:5. 
Oue example found by Dr. Robert Pulleine in the rejecta- 
menta of the River Wakefield, at Balaklava, S.A. 
This species by its lirate ornament should fall in the group 
Perenna, Guppy, 1867, and on the other hand it has affinity 
with the Zucidella-like species by reason of its dentate peristome, 
a combination of characters which makes it unnecessary to insti- 
tute comparisons. As the genus in Australia belongs mainly to 
the North-East, though reaching South into the coastal tracts of 
the Northern parts of New South Wales, the question naturally 
arises, Is the present species indigenous? or is it an accidental 
importation? But whatever may be its origin, I believe it to be 
undescribed. It may be urged in explanation of its anomalous 
geographic position, that a more marked paradox is furnished by 
Stenopus rusticus, which is restricted to the North-East extremity 
of Queensland and to the coast-cliffs on the east side of St. 
Vincent Gulf in South Australia.
