FAUNA HAWAIIENSIS 



(2) Achatinellidae. In view of their interesting characters I have here dealt 

 with the distribution by genera. 



Species occurring in only one Island. 



The only forms of Achatinellidae found on more than one island are in the 

 genera Leptachatina and Auriculella ; in the former one species is said to be found 

 on Kauai and Oahu, and two on Maui and Oahu ; in the latter similar notes occur 

 with regard to Oahu and Maui, Molokai and Lanai, Maui and Molokai, and (doubt- 

 fully) Oahu and Hawaii. 



Further a single subfossil species of Carelia is recorded from Niihau ; and the 

 following are of uncertain habitat: Buliniella i, Partulina 3, Achatinellastrum i, 

 Ainastra 7, Leptachatina 6, and Ajiricnlclla 2. 



(3) The residue of the fauna.
