with an intense brown band around the columella, lip and col- 

 umella tinged with light purple. 



Hab. Bottom of Nuuanu Valley. 



This species in coloring is so like A. decora that Mr. Reeve gave 

 it the name of the "Allied Achatinella," He said, however, that 

 the spire is more acuminate, and the last whorl not so broad and 

 ventricose. I think without doubt it is the same as A. decora. 



lo. Achatinella albofasciata Smith.
