64 Mr. H. Suter on the Relation between the 



6ic. ('.Nautilus/ 1892, vi. p. 57). On looking through my 

 collection of Tasmanian land-shells I fortunately found many 

 specimens containing the dried-up animal, and these I decided 

 to sacrifice to enable me to examine the dentition. Moreover, 

 a short time ngo Mr. W. L. May kindly assisted me by for- 

 warding some living snails from Tasmania. 



In giving the classification of some of the Tasmanian 

 land-shells, I wish to point out that it is based on the den- 

 tition as well as on the shell-characters. The descriptions 

 and figures of the dentition of the species will be published 

 occasionally. The dentition of the following thirty-two 

 species was examined : —
