A REVISED CENSUS of the TERRESTRIAL 

 MOLLUSCA of TASMANIA. 



By W. F. Petterd (Launceston) and C. Hedley, Conchologist. 

 (Plates lxxxii.-lxxxvii, and fig. 16.) 



This paper is confined to the rehabilitation of species. We 

 have endeavoured to supply illustrations of all Tasmanian land 

 shells hitherto unfigured, to simplify the tangled synonorny and 

 to arrange the species in genera and higher groups in harmony 

 with modern classification. 



Our work has been facilitated by the loan of the collection of 

 the Tasmanian Museum, for which we are indebted to the kind- 

 ness of the late Mr. Alexander Morton, the then Curator. 

 Examples of most of the species have been added to the Australian 

 Museum Collection.
