Tadine, Mare, Loyalty Islands (CNHM 
109380) 
A single, slightly subadult specimen provides 
the first New Caledonian record for this Poly- 
nesian species. D. conula is widely distributed 
in the Society and Cook islands and has been 
reported from Rurutu in the Austral Islands.

Lacteoluna sp. 
River drift at sea coast a few miles from 
Bourail, New Caledonia ( ANSP 151005) 
Two worn specimens (ANSP 151005) are 
easily recognizable as thysanophorine. They may 
be the young of Lacteoluna selenina (Gould). 
As in the case of Varicella, this is the first Pa- 
cific record of a West Indian group. 
II. NONMARINE MOLLUSCA INTRODUCED INTO 
NEW CALEDONIA 
The New Caledonian land snail fauna contains 
a number of species that are obvious introduc- 
tions from other parts of the world, several 
species that were spread through the Pacific by 
primitive man, and a few disharmonic elements 
that, although not yet equated with foreign 
taxa, are probably human imports. Collecting in 
the islands was very extensive from 1850 to 
1880; thereafter only casual collections were 
made until 1911, when Sarasin and Roux as- 
sembled the materials reported on by Dautzen- 
berg (1923) and Grimpe and Hoffmann (1925). 
In 1928 T. D. A. Cockerell gathered the speci- 
mens listed in Solem (I960), and in 1958 
Borys Malkin collected the specimens reported 
on above. Each collection revealed new addi- 
tions to the introduced fauna, but the widely 
separated periods of collecting make informa- 
tion as to the time of arrival impossible to 
establish for the majority of the imports. Some 
records exist for introduction of ornamental 
and food plants ( Guillaumin, 1942), but no 
notice was taken of snails that might have been 
hidden in the soil-matted roots or sealed to the 
underside of a leaf. In nearly every case, all we 
can say is that a particular snail was established 
prior to a certain date. Despite the limited evi- 
dence as to time of introduction, the areas of 
origin of the introductions form a coherent 
pattern worth recording.
