I took over three hundred examples of this species, all obtained in a small 

 area of about one-half an acre, and nearly two miles inland, at Rarotonga. 

 Though carefully searched for, I failed to discover a single example in any other 

 part of the island. 



It is more elevately dome-shaped than the two preceding species, and the 

 whorls are more depressed, and only the first two or three whorls are ribbed. The 

 carination is smaller, smoother, and there is but one lamina on the parietal region. 



Libera, n. sp. 



This is undoubtedly the smallest species of the genus. Only five examples 

 were found in the low-land forests at Aitutaki, and are deposited in the Godeffroy 

 Museum, Hamburg.
