Land and Freshwater Shells from Rotuma Island. 519 
LXIT.—On a Collection of Land and Freshwater Shells 
jrom Rotuma Island. By Epaar A. SMItH. 
In April 1896 the British Museum received from Mr. R. B. 
Leefe, H.M. Vice-Consul at the Tonga Islands, a series of 
land and freshwater shells which he collected during a visit 
to Rotuma. The collection contained one species of Partula, 
an Opeas, one Felicina, an Omphalotropis, and a Melania. 
Mr. J. Stanley Gardiner has kindly placed in my hands 
for examination the specimens which he obtained in this 
island, and which he believes to be a “ tolerably complete 
collection.” In addition to the species found by Mr. Leefe, 
his series includes one Lthytida, two species of Charopa, a 
Tornatellina, a Succinea, and a second species of Heltetna. 
Besides these land-shells, Mr. Gardiner also collected some 
Auriculide and Littorinide, some of which were obtained 
over a hundred feet above the sea. He paid ‘a good deal 
of attention to collecting these, searching the tops of several 
of the hills as well as the valleys,” and he thinks “the col- 
lection, though small, is fairly representative. ‘There is no 
indigenous forest left anywhere on the island.” 
Rotuma, or Rotumah, is situated about 300 miles N.N.W. 
of Fiji. As no Mollusca have hitherto been recorded from 
this locality, the following list may have some interest. 
The land Mollusca are similar in general characters to 
those occurring in the nearest groups of islands; and out of 
the ten species six appear to be peculiar to theisland. Some 
of these being obscure forms and difficult of determination 
may, however, eventually prove to be slight variations of 
already known species. 
None of the Auriculidee and Littorinide, which usually have 
a more extended range than terrestrial Pulmonates and 
Operculates, are restricted to Rotuma.
