New Records of New Caledonian Nonmarine Mollusks and 
an Analysis of the Introduced Mollusks 
Alan Solem 1 
/ 
The illustrated handbook of New Cale- 
donian nonmarine mollusks issued by Franc 
(1957) has been supplemented by an annotated 
check list (Solem, 1961). Additional records 
are given by Solem (I960), and material col- 
lected by Borys Malkin between July and Oc- 
tober 1958 is reported on here. A few notes on 
specimens from other sources are included, par- 
ticularly on two very puzzling shells omitted 
from Solem’s discussion (I960) to allow more 
critical examination. The location of cited ma- 
terials is indicated by the following symbols: 
ANSP (Academy of Natural Sciences, Philadel- 
phia), bpbm (Bernice P. Bishop Museum, Ho- 
nolulu), CNHM (Chicago Natural History Mu- 
seum). In each case the catalog number of the 
set is indicated to facilitate later efforts to con- 
sult the cited specimens. 
Many of the Loyalty Island records are new, 
but the most important data are the addition 
of six species to the New Caledonian fauna, all 
of them introduced from other areas. Elasmias 
apertum ( Pease ) , Lamellaxis micro, ( Orbigny ) , 
Opeas oparanum (Pfeiffer), Varicella sp., Dia- 
stole conula (Pease), and Lacteoluna sp. were 
not previously known from New Caledonia. 
I. RECORDS OF NONMARINE MOLLUSKS 
The following locality records were thought 
worthy of publishing. With minor alterations, 
the sequence of species follows Solem (1961). 
References to previous literature can be located 
in Solem ( 1961) and are not repeated here.
