Vol. XXXIX: Supplement THE FESTIVUS Page 23
APPENDIX 1: AN ANNOTATED TAXONOMIC COMPILATION OF THE
RECENT MOLLUSCAN FAUNA OF ÎLE CLIPPERTON
Appendix 1 represents a total of at least 285 generally accepted records, including: 36 Bivalvia, 248 Gastropoda
(2 Pulmonata), 1 Polyplacophora, and an undetermined number of Cephalopoda. There are 42 species that are
considered either spurious, doubtful or have been synonymized and are listed in Appendix 2 (rejected records). A
review of the zoogeographic affinities of the taxa can be found in Appendix 3.
The following checklist consists of three columns. The first contains both the plate and figure number(s) for each
species illustrated. The second column is a comprehensive list of each taxon and author. The classification system has
been followed as outlined in Keen (1971), and updated by Skoglund (2001, 2002), Ponder & Warén (1988), Vaught
(1989), Meyer (2003), Abbott (1989) and Geiger & Thacker (unpublished data). The third column, Literature
Sources/Remarks, has as its first entry the initial published record, often with type number or collection number entry
for each species known to occur at Clipperton. Following in chronological order are Clipperton references that have
been cited for each taxon. References in bold denote that the authors cited have examined/collected the material.
References not in bold indicate that the cited records are from previous sources, either published or in collections. A
plus sign (+) after a collections number indicates that there are too many lot numbers to list. Photographic image
references and additional records with institution and private collection numbers are included.
Under Remarks the years noted are from one or more of the four expeditions (1994, 1998, 2005, 2007) during
which the species was collected. Condition when found is also noted: empty shell or live animal and if preserved in
95% EtOH (wet collection).
