SMITH : ATJSTEALIATT LAND-SHELLS. 87 



This species is well characterized by the peculiar dentiform thicken- 

 ing of the columella and the ridge which arises from it, and passes up 

 the very contracted umbilicus. It is about the same size and shape 

 as '■'Helix riistica^^ of Pfeiifer, found on the opposite side of Australia, 

 but differs in the umbilicus and columella.

 occur in the same locality and were both collected by Mr. G. Masters.
