On the Classification of the Helicterimv. By Harper Pease. 



Helicter, Fer., was described in 1821, and has eight years 

 priority over Achatinella, Swains., 1828. Eleven subgenera have 

 been described by authors, which are retained as genera and two 

 new ones added. 388 species have been described, of which 166 

 are considered synonyms, leaving 222 species believed to be dis- 

 tinct. The species are entirely confined to the Sandwich Islands. 

 The new genera proposed are : 



Eburnella, type Ach. casta, Newcomb. 

 Perdicella, " " Alexandri, Newc. 



The diagnosis of each genus is given, with lists of species, re- 

 marks on distribution and synonymy.
