A very common species, distributed throitghout all the Polynesian islands, and 
extends its range to the East Indies. They range from near high-water mark to over 
2000 feet above the level of the sea. 
For further remarks on this species, see my paper on the Cook’s Islands land shells, 
published in the Journal of the Academy of Natural Sciences of Philadelphia. 
Genus PARTULA, Ferussac. 
The genus Partula, so far as known, is restricted to the Pacific islands, ranging 
from the Marquesas throughout all the groups as far west as New Guinea ; but is not 
found in New Zealand, nor New Caledonia, nor Australia. North of the equator, 
they occur at the Caroline, Pelew and Marianne Islands, the latter being the northern 
limit of the genus. They are entirely absent from the Sandwich group, where they 
are represented by the closely allied genus Achatinella. Neither do they occur on any 
of the low coral islands. 
It is now a well-known fact that each group, with one exception, is inhabited by 
peculiar or endemic species. The solitary exception is P. hyalina, whicli has its 
metropolis in the Austral Islands; is also found on Mangaia, one of the Cook’s group, 
as well as at Tahiti. 
The Society Islands, which are inhabited by nearly one-balf of the known siiecics 
of Partula, may be regarded as the central point of distribution of the genus. Out 
of fifteen subgenera lately established hy Dr. Hartman, ten are found in the group, 
and, besides the type, which is peculiar, seven of his subgenenc types are found 
no\4ere else. It is also the only group possessing strictly ten-estrial or ground
