CLASSIFICATION. XV 



Systematic List of species and subspecies of Achatinellidcz. 



Numbers following the species refer to pages where they 

 are described. In Partulina, where there are several col- 

 lateral phyla, no linear arrangement can be made which will 

 show the affinities with Newcombia and Achatinella, and at 

 the same time preserve a logical sequence of groups and 

 species within the genus.
