KAISER 1 Research Associate, Santa Barbara Museum of Natural History, 2559 Puesta del Sol Road, Santa Barbara, California 93105, USA E-mail: kirstie.kaiser@gmail.com Abstract: Scientific expeditions to fie Clipperton were undertaken in 1994, 1998, 2005 and 2007 to investigate community compositions both on and around this uninhabited coral atoll. These studies have allowed a reevaluation of the molluscan biodiversity of the most isolated oceanic island of the tropical eastern Pacific (TEP). Prior to this current work, the last complete study (Emerson, 1994) listed a total of 92 mollusk species at Clipperton. The known molluscan taxa are herein significantly increased 210%, for a total of 285 species. This is assuredly an underestimate, especially for species inhabiting deeper water which has yet to be adequately sampled. The majority of taxa are illustrated by photography and scanning electron microscopy. An inter-oceanic island biogeographic comparison and an annotated species list are included. Figure 1.

Introduction lie Clipperton (Figures 1 ,2) is considered one of the five groups of remote oceanic islands of the tropical eastern Pacific (TEP) which are of particular biogeographic interest. These islands pose questions relating to dispersal and endemism in comparison to the other island groups of the TEP and tropical west American mainland fauna.

Geiger. nature of insular biota relative to immigration and distributions, Newman (1996) gave a historical review and insight into oceanic islands. The five tropical eastern Pacific oceanic groups are: Islas Revillagigedo, Mexico (18°N); He Clipperton, French possession (10°N); Isla del Coco, Costa Rica (5°N); Isla de Malpelo, Colombia (3°N), and Islas Galapagos, Ecuador ((f) (Figure 2). They are all separated from the mainland by abyssal depths. Malpelo is closest at 435 km and Clipperton farthest at 1,280 km. The molluscan fauna has been intensely studied in the Galapagos (Finet, 1994; Kaiser, 1993, 1997). Kaiser & Bryce (200 1 ) published an extensive monograph on the mollusks of Isla de Malpelo. Two major papers have been published on the Islas Revillagigedo (Emerson, 1995; Reyes-Bonilla, 1999). A number of notable expeditions have visited Isla del Coco in the 1980s and 1990s, but only preliminary reports have appeared (Montoya, 1983; Shasky, 1983a, 1989a; Montoya & Kaiser, 1988; Chaney, 1992; Mulliner, 1993; Kaiser, 1998; J. Hertz & Kaiser, 1998a, b; Kaiser, 2001; Kaiser & C. M. Hertz, 2001). A French possession, Clipperton is characterized by its extreme isolation, small size, and most importantly, low habitat diversity. These physical parameters have contributed to its greatly impoverished molluscan fauna in comparison to other TEP oceanic islands. First discovered in 1711 as “Isla de la Pasion” (Skinner & Schmieder, 1996), the only atoll of the tropical eastern Pacific, which is much nearer to the American mainland than to the nearest Pacific islands to the west, has long intrigued biogeographers. Collections of marine fauna including fishes (Allen, 1995, Robertson & Allen, 1996; crustaceans (Poupin et al . , in press); corals (Glynn et al., 1996; Carricart-Ganivet & Reyes- Bonilla, 1999; Flot & Adjeroud, in press); echinoderms (Solis-Marin & Faguarda Figueras, in press) have revealed that both tropical eastern Pacific (Panamic Province) and substantial Indo-Pacific elements are represented. In that Clipperton is the easternmost atoll of the vast area known as the East Pacific Barrier and the westernmost island of the tropical eastern Pacific, the high percentage of Indo-Pacific fauna (33.5%) is due to two factors. Firstly, the atoll is unique in that it is situated in an overlap zone of the Pacific Ocean and. Vol. XXXIX: Supplement THE FESTIVUS Page 3 therefore, is the first land mass to be intermittently exposed to the North Equatorial Countercurrent from the west which brings source elements including planktotrophic larvae across the Barrier. The nearest atoll Pukapuka, in the Tuamotu Archipelago, is 4,280 km to the southwest and the closest island is Ua Huka of the Marquesas and is at a distance of 3,965 km. Secondly, low habitat diversity of the atoll, which is mainly prolific coral cover, makes suitable habitats for these planktonic links from the west. Those source elements from the east on the North Equatorial Current encounter a lack of the coarse intertidal and subtidal environments of the coastal diversity. Clipperton lacks the rocky shores, mud and sand bottoms, mangroves, and such food sources as marine algae and other plants that are necessary to establish a hold and maintain viable populations for many west American mainland (TEP) taxa. Physical Environment ile Clipperton located at the nexus of the Panamic Province (10°18'N and 109°13'W), is somewhat characteristic of Pacific atolls having volcanic foundations. Where the top of the highest peak of the submarine Clipperton Ridge, described by Menard & Fisher (1958), reaches the surface of the sea, an egg- shaped coral reef supports a narrow, low, uninterrupted land strip of limestone debris with a single cavernous mass of altered trachyte rising to approximately 20 m (Clipperton rock) on the southeastern border. Clipperton is a “near atoll,” since a true atoll has no volcanic outcroppings. The small ring is 11.8 km in circumference, with only 1 .7 square km of exposed land encircled by a healthy fringing coral reef (Figure 1). The lagoon, which makes up 85% of the atoll, is surrounded by a ribbon of land variable in width from 25 m to 320 m (pers. comm., John Munch, 2007). Beyond the wave- washed outer ring of the atoll are reef-flats lined by coral-sand beaches or cobble strands. From there, white ridges of unconsolidated limestone fragments (coral bits) reach a maximum elevation of four meters from where the land mass slopes down and encloses the sizeable (7.2 km square) central lagoon. The lagoon has sediment of fine organic debris and hordes of minute biting isopods ( Cirolana sp.) Poupin, pers. comm, 2007). Clipperton has a landing strip built in 1944 on the northwest side of the widest part of the atoll. The strip consists of coral pieces that are stained dark gray or black by microscopic algae and is not recommended for use today. The following eight habitats are represented at Clipperton and environs: (1) large deposits of storm-generated coral, with one extensive volcanic outcropping, bordering an intolerably low salinity lagoon (Figure 3), Figure 3. Aerial view taken from the south of Clipperton Rock located on the edge of the lagoon, 2005. Photo: C. Fresser. (2) a shallow, often tidally exposed reef front with low coral cover and abundant crustose coralline algae (Figure 4), Figure 4. Tidally exposed reef front on west side of Clipperton, 2005. Photo: C. Fresser. Page 4 THE FESTIVUS Vol. XXXIX: Supplement (5) a coral-dominant zone, in pristine condition, beginning at or slightly below the wave base (15-20 m) and descending precipitously down to 40 to 55 m (Figure 7), Figure 8. Antipatharia sp. on coralline sand and rubble slope, 60-70 m, 2007. Photo: J. Bozanic. (7) below 70 m the silty sand and rubble slope continues to decline to a maximum observed depth of 100 m with no black coral growth but with significant thermoclines (pers. comm., Jeff Bozanic, 2007), (8) in the north-northeast sector of Clipperton is a 60 m terrace that is 1,200 m off shore (Glynn et ai., 1996).

(6) a coralline sand and rubble slope starts at the end of the reef-building corals and goes to 60-70 m. It supports healthy colonies of black coral species (Figure 8), (3) a windw'ard spur and groove zone with low coral cover in 2 to 10 m depth consisting mainly of Pocillopora spp. (Figure 5), Figure 6.

(4) a gently sloping 20 meter terrace of reef building corals, mainly Porites lobata (Figure 6), Vol. XXXIX: Supplement THE FESTIVUS Page 5 was most likely closed off by severe storm alterations between 1839 and 1858 (Sachet, 1962b). According to Skaggs (1989), the southern entrance to the lagoon was closed before 1861. The greenish, murky lagoon is complete with dead coral reefs consisting of Pocillopora spp. and Porites spp. several meters in thickness indicating active reef growth in the recent past. At least three species of marine fishes and several plant species are thriving in the surface lagoon waters as of 2007. Beginning at 12 to 15 m the water quality changes from a plankton rich environment to water containing high concentrations of hydrogen sulfide. Below the density interface (18-34 m) can be found a layer of gelatinous organic material which is quick to make the visibility go to zero if disturbed (Figure 9). The low salinity of the present day lagoon is a result Figure 9. Jeff Bozanic, at 34 m, reaching into gelatinous layer of the Clipperton lagoon, 2007. Photo: J. Bozanic. of its isolation from the sea; only large storm waves wash into it, and there is dilution due to high rainfall during the summer and fall seasons. This stagnant body of water supports the common gallinule, the only non- seabird that breeds on Clipperton, and the abundant aquatic plants along some areas of the shore which help maintain the large land crab population (Figure 10). Figure 10. Clipperton’s large population of land crabs feeding on the lagoon plant life, 2005. Photo: S. Hourdez. Clipperton has a seasonably humid tropical climate. Very few data had ever been collected until the Jean- Fouis Etienne Expedition in 2004-2005. Rainfall is very high during the month of October and continues until December. Severe thunderstorms were noted in March, April (pers. obs., Kaiser, 2007), and May (Figure 1 1). Storms and occasional hurricanes come from the north and are known to devastate the island.

Page 6 THE FESTIVUS Vol. XXXIX: Supplement Though once completely barren, Clipperton now has large groves and isolated individual coco palms, presumably descendants of trees that were planted in the early 1900s by a Mexican garrison (Figure 12).

Malacological History of Clipperton Discovered in 1527 by the Spanish captain Saavedra Ceren, Clipperton has been claimed at one time or another by the United States, France, Mexico (Gonzalez Avelar, 1992) and England. The island has been called L’ile de Passion and several other names by mapmakers. The origin of Clipperton’s current name dates to 1705 when an English pirate, John Clipperton, went ashore. During the past century, the isolated, uninhabited coral atoll of Clipperton has been visited by several prominent expeditions. Here I mention those studies relating to the molluscan fauna, either in museum collections, published or in preparation. Sachet (1962c) indicated that the first mollusks reported from Clipperton were mentioned by John T. Arundel in 1897 in a San Francisco newspaper article. They were described as pearl oyster shells without specific names but most likely they were Pinctada mazatlanica (Hanley, 1856), which occurs at Clipperton (Plate 2, figures 6a, b). Sachet (1962b) also mentioned that a “group of shells” in the USNM were received in 1897 from a Mr. Arnheim, a ship chandler who obtained them from sailors. Possibly the first mollusks collected for scientific study were gathered by Washington Henry Ochsner, a member of the shore party on 10 August 1905 from the schooner Academy on a voyage of the California Academy of Sciences (CAS) to the Islas Galapagos (Slevin, 1931). In the few hours on Clipperton, eleven species were taken by Ochsner. Hertlein ( 1937) reported on them and figured six species. Dali (1910) mentioned three species of Conus from Clipperton. The specimens are located in the Recent mollusk collection of the National Museum of Natural History, Smithsonian Institution (USNM) and are from the 1897 Arnheim Collection and the CAS voyage of 1905 (pers. comm., P. Greenhall, 2006). Bartsch and Rehder (1939) reported on 12 species occurring at Clipperton. Five were described as new and had been collected on and among the rocks by W. F. Schmitt (USNM) in May 1938 while on the “Presidential Cruise” aboard the U.S.S. Houston. The U.S. Navy Electronics Faboratory “Shuttle Expedition” in May 1952 did only incidental scientific research, but it produced the first deep-water specimens from Clipperton. Hertlein and Emerson (1953) documented 31 previously recorded species, and added five records to the malacofauna including one new species. The new records were collected from the Expedition’s two dredge hauls from 183-367 m off Clipperton’s east slope. During the early 1950s, at the beginning of his career, William K. Emerson, now emeritus of the American Museum of Natural History in New York, took a special interest in the zoogeographic study of mollusks having Indo-Pacific faunal affinities and their migration to the tropical eastern Pacific. His first paper on the subject was co-authored with Hertlein when they were both working in the San Francisco Bay area (Hertlein & Emerson, 1953). Throughout Emerson’s distinguished career in malacology he continued to pursue answers to the questions of what, why and how mollusks came from the west across the great Pacific Ocean (Emerson, 1967, 1968, 1978, 1982, 1989, 1991, 1993; Zinsmeister & Emerson, 1979). According to Hertlein and Emerson (1957), on 12 December 1954 three members of the Scripps Institution of Oceanography (SIO) “Acapulco Trench Expedition” landed on the atoll from the research vessel Spencer F. Baird. In only a few hours they managed to collect 14 species of mollusks, including two new records, from beach drift and the intertidal zone. They reported no living marine invertebrates in the lagoon. During the second and third International Geophysical Years, Scripps Institution of Oceanography carried out a number of research cruises. The first expedition landed and stayed 20-26 October 1956 followed by another eight- week expedition in August - September 1958. American scientists participating in the Vol. XXXIX: Supplement THE FESTIVUS Page 7 1958 “Doldrums Expedition” aboard the research vessel Spencer F. Baird, focused mainly on sea and weather conditions. A number of biologists were left for two and a half weeks (7-26 August 1958) to study the flora and bird fauna of Clipperton. The year 1958 was a new era for scientific collecting because SCUBA was used for the first time at Clipperton. The maximum depth was 40 m and diving at all depths was seriously restricted by the necessity to use a shark cage for protection from the prolific shark population (Figure 13). Emerson (1993) recounted a harrowing tale from Carl L. Hubbs (SIO) (in litt. to Charles M. Breder, 14 March 1957) as follows: “The outer margin [of Clipperton] is so excessively full of sharks, the collectors are not very anxious to work there. The sharks were so numerous that they actually bit the oars of boats being rowed along the shore, and paid very little attention to shark repellent. In fact one of them came in and swallowed the bag of repellent that was used in a vain effort to get in collecting at a certain spot.” Figure 13. Silky shark off Clipperton, 1994. Photo: J. Black. Allison (1959), one of the “Doldrums Expedition” scientists, reported on the occurrence and habitat of five species of Conus found at the Island. Following that, Hertlein and Allison (1960a) listed 12 species of Cypraea that were primarily collected on the 1956 and 1958 Expeditions. A third contribution in the series by Hertlein and Allison (1960b) listed 34 species and included all other mollusk family representatives collected on the two Expeditions. A remarkable scientist on the “Doldrums Expedition” was Marie-Helen Sachet, a French botanist. Sachet was charged with making a comprehensive survey of life on the atoll and made significant contributions in studying the geology and the marine and terrestrial flora and fauna of Clipperton, including the most comprehensive list of mollusk species for that time (Sachet, 1960, 1962a-c, 1963). During the 19-day stay on the island, 58 pigs, which had been introduced at the end of the 19th century, were eradicated. Their thought was to give the marine bird populations (Figure 14), land crabs ( Gecarcinus planatus) (Figure 15), and other fauna a better chance of survival. Figure 14. Masked boobie pair with chick (Sulci dactylatrci) and persistent land crab. 2005. Photo: C. Fresser. Figure 15. Bright orange Gecarcinus planatus Stimpson, 1860, moving boobie egg to its lair, 2005. Photo: J.-M. Bompar. Eight years after its first visit, SIO’s R/V Spencer F. Baird, during the “Carrousel Expedition” of 1964, brought up mollusks during dredging operations around Clipperton. Hertlein & Allison (1966) reported on 35 species from the 92-meter dredge hauls, along with all other mollusks recognized in Clipperton collections that had not been previously inventoried. Unfortunately, the present repositories of the specimens are unknown. Still examining unidentified material collected on Page 8 THE FESTIVUS Vol. XXXIX: Supplement the 1958 Expedition, Hertlein and Allison (1968) described six new species, of which five are here considered valid. They also reviewed three previously described mollusks and discussed one unnamed species of the genus Omalogyra (Plate 36, figures 7a-c), which occurs at all of the TEP oceanic islands and remains without a specific name to this day. Beginning in 1966 and reaching completion in 1968, the French Centre de Recherches du Service de Sante des Armees (Research Center of the Health Service of the Armies) pursued the natural history of Clipperton on four “Mission Bougainville” Expeditions. From those Expeditions, Salvat and Ehrhardt (1970) listed 89 species of mollusks, noting their biogeographic affinities and commenting on ten of those more extensively. Salvat & Salvat (1972) brought the number to 90 by adding the bivalve Pinna rugosa Sowerby, 1835 (Plate 3, figure 6) to the list. In order to answer a number of urgent questions for the French government about developmental schemes for Clipperton, several preliminary expeditions were sent to Clipperton between 1975 and 1980. Jacques Cousteau, chief scientist Pierre-Marie Niaussat, plus 23 others aboard Calypso , lived on and studied the island for six weeks in 1980. The scientific team focused mainly on the brackish- water lagoon (diving to 40 m) and to a lesser degree, on the bird and the ubiquitous land crab populations which had flourished after the feral pigs had been exterminated in 1958. Several beach worn mollusks were collected by Spencer Luke (SIO), one of the Expedition scientists and remain in the Scripps Institution of Oceanography Collections. Other than sport and commercial fishermen (Figure 16) landing on Clipperton and some reporting their beach finds (Perrin, 1977; Schneider, 2004), Clipperton had a lull in visitors, especially from the scientific community, for the next 17 years. In 1992, under the auspices of the Santa Barbara Museum of Natural History, I initiated a scientific expedition co-organized with John D. Jackson (Appendix 4). We specifically designed the trip to explore the submarine environs of Clipperton with SCUBA, limited dredging and tangle net deployments. In April 1994, 22 members of the “Clipperton 1994 Expedition” departed San Diego, California. Five members of the 22 participants logged over 160 hours of diving for mollusks (Chaney, 1994; Appendix 4, figure 26). The research team examined virtually all parts of the island while living and diving from the M/V Royal Star. With renewed interest, and prior to the 1994 Clipperton Expedition, Emerson (1994) researched the Figure 16. Mexican commercial tuna seiner off Clipperton's west side during inclement weather. 2005. Photo: C. Fresser. museum collections and literature in order to compile the most comprehensive zoogeographic summary of Clipperton mollusks to that date. The inventory included 92 species composed of 70 gastropods and 22 bivalves. Following the “Clipperton 1994 Expedition,” Small (1994, 1995) and Beals (1995), participants of the mollusk team, did initial reports of our findings. Three years later, aboard the R/V El Puma , the “SURPACLIP-I” cruise organized by the Universidad Nacional Autonoma de Mexico made a short visit to the island from 23 to 25 November 1997 as part of their oceanographic expedition. Researchers Carricart- Ganivet and Reyes-Bonilla (1999) presented a complete study of the scleractinian corals, but the few mollusks collected on Clipperton were unfortunately lost in the mail en route from the Natural History Museum of Los Angeles County (pers. comm., H. Reyes-Bonilla, 2007). In 1998, Dr. D. Ross Robertson from the Smithsonian Tropical Research Institute, Panama (STRI), a participant in the 1994 Expedition, organized the “STRI Clipperton Expedition” taking the Institute’s research vessel, the R/V Urracd to Clipperton. Departing from Acapulco, Mexico (Appendix 4), while living aboard the R/V Urracd from 17 April to 10 May, I was one of eight scientists. We collected, using SCUBA and otter trawl, and carried out field observations mostly concentrating on the fish fauna. The French “Expedition Clipperton” organized by Jean- Louis Etienne, was by far the most serious effort to assess the molluscan fauna of Clipperton. The object- Vol. XXXIX: Supplement THE FESTIVUS Page 9 tive of this land-based Expedition from December 2004 to April 2005 was to explore and observe the land and marine flora and fauna and to study the lagoon and environment of the island (Charpy, L., [editor], in prep. Clipperton: environnement et biodiversite d’un microcosme oceanique). The participants and provisions were shuttled 1,230 km to and from Acapulco, Mexico to Clipperton by the motor schooner Rara Avis on a revolving schedule every three weeks (Appendix 4). Land-based accommodations were set up, and during the rotations, scientists lived and worked on and from land. The Island was temporarily transformed into a biological laboratory and Figure 17. Author working up material in temporary wet lab, 2005. Photo: S. Hourdez. offered excellent working facilities (Figures 17, 18). I participated in the 13 January through 1 February 2005 rotation researching and collecting marine and terrestrial mollusks with participants from the Museum national d’Histoire naturelle, Paris, and other French institutions. We were diving to depths of 55 m, utilizing airlift pumps which generated an unprecedented volume of material. Techniques including limited algal shakings and coral brushings supplemented the samples which were described by Bouchet et al. (2002) from their work in New Caledonia. The three lagoon dives and some intertidal collecting added additional mollusk records, over 33 in all. Two years later Alicia Hermosillo (opisthobranchs), Pedro Medina Rosas (corals) and I were part of the “Expedition lie Clipperton 2007" aboard the M/V Nautilus Explorer (Appendix 4), which included three extra diving days at the Islas Revillagigedo. Six days from 14 to 20 April 2007 were spent at Clipperton. Very little intertidal work was done because of high Figure 18. Port Jaouen (diving operations) in front of landing site, 2005. Photo: S. Hourdez. Figure 19. Pedro Medina Rosas. Alicia Hermosillo and the author on stern of the M/V Nautilus Explorer, 2007. Photo: R. Chavez Arce. breakers from the inclement weather which made landing both times on the island very hazardous. Among the three of us, a total of 18 dives with SCUBA were made in search of new mollusk records (Figure 19). A concerted effort was given to the opisthobranch fauna of the island which added four new records to the faunal list. For the first time at Clipperton, divers used Page 10 THE FESTIVUS Vol. XXXIX: Supplement rebreathers for collecting from 46-91 m (150-300 ft) off the fringing reef where a number of new records were discovered. I was not able to process the micro-material collected within a timely manner for inclusion in this manuscript, although most of the larger species records for 2007 are noted in Appendix 1. The complete opisthobranch data gathered by Alicia Hermosillo and others are included herein. An addendum is planned for the remainder of the mollusks in the near future. Materials and Methods In the course of the four expeditions, more than 133 stations were sampled on and around Clipperton between the high tide mark and 113 m depth. The most prolific amount of material was collected by using SCUBA (2 to 91m). Other methods included four productive dredge hauls from 109 to 113 m (1994 and 1998) and two successful deployments of tangle nets, one at 49 m (1994) and one at 63 m (1998). There was one productive benthic grab at 92 m (Figure 20) and many hours of intertidal sampling by hand around all sections of the island. A total of seven dives between 10 m and 38 m were done in the lagoon during the 2005 and the 2007 expeditions (Appendix 4, figure 26). Collecting methods used while diving included: hand picking with the naked eye; brushing and shaking dead coral and rubble into a canvas bag (Figure 21); Figure 21. The author using the canvas-bag method for collecting micro-mollusks. Photo: J. Bozanic. breaking hard corals for boring organisms (usually done inadvertently by the anchor chain) and suction sampling. The suction method was used exclusively in 2005. and the technique involved a two-meter long aspirator powered by a generator. The attached lift bag was then deployed to bring the samples to the surface. Special Figure 20.

Chavez Arce. attention was given to associations between mollusks and various invertebrates, particularly echinoderms and scleractinid and anthozoid corals. In all. approximately 350 man hours were spent searching for mollusks while on the four expeditions (Figure 26). Many hundreds more hours were spent in the laboratory sorting, cataloging and imaging the specimens. Field samples were processed fresh by sieving in seawater and fractioning to size classes down to 0.5 mm. Fractions over 5 mm were sorted and placed in 95% EtOH and later individually sorted, cataloged and preserved in 95% alcohol or dried with animal if live collected. The smallest samples (under 0.5 mm) were washed in fresh water and dried for later sorting with a dissecting microscope and then cataloged. The opisthobranchs (excluding the holoplanktonic families) were either photographed in situ or “tub shots” w'ere taken later. Most of the larger voucher specimens were photographed at the SBMNH with a Nikon D1X digital camera while the smaller specimens (<5 mm) were imaged there with the Zeiss EVO40XVP (SEM).

USNM, National Museum of Natural History, Smithsonian, Washington, D.C. WAM, Western Australian Museum, Perth, Western Australia Discussion Appendix 1 is a detailed inventory of the molluscan species found at Clipperton including the last four expeditions. The species were identified based on specimens in the Kirstie L. Kaiser reference collection and many museum collections, especially the Santa Barbara Museum of Natural History. Select specimens were sent out to specialists as indicated in the acknowledgments. Many specimens could not be identified with certainty to species-level. The micromollusks ( < 5 mm) were the most difficult group as most families are poorly known with the last revisions dating to the late 19lh and early 20Ih centuries. Juvenile specimens were also difficult to identify; in several instances, the species-specific characters only develop later in their ontogeny. The species are identified here to the most accurate taxonomic level possible. The Scissurellidae are illustrative of the problems of identification. A single species, Sinezona rimuloides Carpenter, 1865, had been known to occur at Clipperton since 1994 (Kaiser, unpublished data). It was identified as the only known species in the family from this region until Geiger (pers. comm., 2006) recognized two additional species; one he described as Scissurella kaiserae Geiger, 2006, and the other one is in the process of being described (Geiger, unpublished data). The Scissurellidae sp. 1 record in Appendix 1 is based on two broken specimens from the University of California, Berkeley Collection. The positive identification of the specimen is under study using scanning electron microscopy. A second taxonomic problem arose with Chama rubropicta Bartsch & Rehder, 1939. It had been synonymized under C. buddicinci C. B. Adams, 1852, by Keen (1971). Bernard (1976) identified two Chama species at Clipperton: Chama squamuligera Pilsbry & Lowe, 1932, and Chama buddiana (= C. rubropicta). Of the two species of Chama that are found at Page 12 THE FESTIVUS Vol. XXXIX: Supplement Clipperton, the species with red to orange coloration is distinct from both C. squamuligera and C. buddiana from the Golfo de California and the continental coast of west America. I consider these specimens from Clipperton to be Chama rubropictci and it is here reinstated as a valid species. The bivalve fauna is dominated by species that attach to hard substrata or are boring therein. There is a notable lack of infaunal bivalves which constitute the majority of species in most marine environments. The total of 36 bivalve species found at Clipperton are reflective of the particular substrata encountered. The two infaunal species in Lucinidae were recovered from the lagoon as empty shells; they are remains of species that thrived at a time when the lagoon was open to the ocean and fully marine as opposed to the brackish condition encountered today. Records of Rochefortinci sandwichensis (Smith, 1885) and Streptopinnci saccata (Linnaeus, 1758), in conjunction with Codakia punctata (Linnaeus, 1758) show a biogeographic connection with the Indo-Pacific islands. The majority of the 28 identified bivalve species are from the Panantic Province. The seven identified species of Vetigastropoda show mostly Panamic affinity with the exception of Diodora granifera (Pease, 1861) chiefly known from Hawaii. The most diverse group within Vetigastropoda is Trochoidea with approximately 3,000 species worldwide (Geiger & Thacker, unpublished data) though only five species have been recorded from Clipperton. Compared to the four species of Fissurellidae (606 worldw'ide: Geiger et al., in press) and four nominal taxa in Scissurellidae (170 worldwide; Geiger et al., in press) the low diversity of Trochoidea is remarkable. There seems to be an inverse proportional relationship between diversity and body size. The overall body-size sequence is from the smallest Scissurellidae to the intermediate- sized Fissurellidae to the rather large Trochoidea. Among Trochoidea the species found at Clipperton are rather small in size for the group. Only two species of Neritoidea have been collected at Clipperton (Neritidae, Plate 12, figures la-b; Phenacolepadidae, Plate 12, figures 2a-c). Species in this group occur mostly in the high intertidal and dysaerobic environments. The intertidal of Clipperton is essentially non-existent, with strong wave action hampering the colonization of the substratum by epifaunal species. This explains the low number of species in this low-diversity group. The Caenogastropoda, to the exclusion of Neogastropoda, comprise 1 14 species. Four intertidal Figure 21. Two Melanella dufresnei parasitizing a sea cucumber. This species of holothurian is the most common at Clipperton. 1994. Photo: R.B. Herrmann. species in Littorinidae have been encountered, half from the Indo-Pacific fauna, half from the Panamic fauna. A rich assembly of microshells were collected predominantly on the underside of rocks, and as empty shells. Species in the Epitoniidae (Plate 18) and Eulimidae (Plates 19, 20) are parasites on sea anemones and echinoderms, respectively (Plate 43, figure 6), (Figure 21). In most, the host-parasite relationship has not been documented, which makes identification more difficult. The species diversity of Eulimidae is surprisingly high. Infaunal species are rare, with two of the four Naticidae (Plate 23) only tentatively assigned to that family. The diversity of Cypraeidae (Plates 24, 25) is high, most likely owing to their long dispersal capability as teleoplanktic, planktotrophic veliger larvae. Most Clipperton Cypraeidae seem not to have established populations because their records stem from empty shells. Of the 51 caenogastropod species identified to species level (excluding the holoplanktonic families), 29 are members of the Indo-Pacific malacofauna, 21 are Panamic and 1 western Atlantic. Species in the Janthinidae, Atlantidae, Carinariidae and Pterotrachaeidae among the Caenogastropoda and Pteropoda (Cavoliniidae and Limacinidae) among the Opisthobranchia, have a holoplanktonic life style. They all have broad geographic distributions, hence their records do not assist in determining the faunal affinity of Clipperton. The 61 Neogastropoda represent the predator guild of the marine fauna. The Muricidae (Plates 28, 29) is the second most diverse faunal element and contributes some of the largest-shelled species collected. Coralliophilinae (Plates 30, 31) are specialized consumers of live coral tissue, and are particularly Vol. XXXIX: Supplement THE FESTIVUS Page 13 diverse at Clipperton. Infaunal neogastropods are rare at Clipperton such as the single deeper-water species of Nassariidae (Plate 33, figures la-b, 2). Of the 50 taxa identified to species level, 22 are from the Indo-Pacific faunal region, while the remaining 28 are known from the Panamic Province. The Heterostropha contain 20 taxa, of which six could be identified to species level; one of those belongs to the Indo-Pacific fauna, while the remaining five are Panamic. The diversity of Architectonicidae (Plate 37) seems high, while the Pyramidellidae (Plates 38, 39) show levels of diversity comparable to other TEP oceanic islands. The Opisthobranchia (sea slugs) are represented by 35 species. Of the 13 taxa identified to species level (excluding the circumtropical holoplanktonic families), ten are circumtropical or from the Indo-Pacific region, while three belong to the Panamic fauna. The mostly infaunal Cephalaspidea (Aglajidae) is represented with a single species, Navanax aenigmaticus (Bergh, 1894), which atypically, for the order, is an epifaunal species on hard substrata. The herbivores (Plakobranchidae, Aplysiidae) as well as spongivores (Umbraculidae, Chromodorididae, Discodorididae, Dendrodorididae) and species feeding on anthozoans (Aeolidiidae, Tergipedidae) are represented at ile Clipperton. Only two pulmonate land snails (Plate 41, figures 3, 4) have been recorded: Opeas oparanum (Pfeiffer, 1846) and Succinea atollica Hertlein & Allison, 1968, the latter described from lie Clipperton. At present, neither species can be found on the island, although both species were common in 1958. I suggest that, perhaps, the land snail populations were negatively affected by the feral pigs and later, to the point of extinction, by the millions of land crabs. Although land snails were reportedly abundant in 1958 (Sachet, 1962c), no subsequent expeditions have encountered them, either living or as empty shells. A single small chiton species described from Isla del Coco, Costa Rica, as Ischnochition victoria Ferreira, 1987, was occasionally encountered living on coralline algae at Clipperton (Plate 43, figures 7, 8). The Cephalopoda are particularly problematic. Octopus spp. and some Octopus spp. paralarvae were collected during the last four Expeditions. Museum holdings contain approximately three to six species, the identity of which can not be further ascertained because a critical review of the region’s cephalopod fauna is wanting (pers. comm., F. G. Hochberg, 2007). The taxa listed from Clipperton (Appendix 1) are predominantly small-bodied species. In some cases specimens collected at Clipperton are notably smaller compared to those collected at the other rocky TEP oceanic islands. For example, the muricid Tribulus planospira (Lamarck, 1822) usually grows to 60-70 mm, but at Clipperton a maximum size recorded for a mature specimen is 41 mm. The turrid Clathurella rigida (Hinds, 1843) usually grows to 8 mm but only attains a size of 4.7 mm at Clipperton. But some of the larger-bodied species, such as Cypraecassis tenuis (Wood, 1828) and C. coarctata (G.B. Sowerby I, 1825) are of comparable size to specimens found on the other TEP islands. In a single case, a world-record size specimen (60.9 mm) of Mauritia scurra (Gmelin, 1791) was collected at Clipperton (Kaiser, 1999). However, Clipperton specimens are generally smaller than those from other populations. In an odd error, Dali & Ochsner (1928) noted a “strictly Indo-Pacific” fauna on Mexico’s Isla Clarion of the Revillagigedo group, but this seems to have been a mistake for Clipperton, because the fauna of Clarion is mainly tropical eastern Pacific (Hertlein, 1937; Kaiser, pers. obs.). Conclusion The Clipperton molluscan fauna as presently known consists of 285 species, of which 182 are here reported for the first time. The majority of species forming new records are illustrated herein. In some cases, newly collected material of better specimens has permitted the identification of formally incertae sedis species and some previously misidentified. From the statistics derived in Appendices 1 and 3, the malacofauna of ile Clipperton, identified to species level, is: tropical eastern Pacific (Panamic) (37.7%); Indo-Pacific (33.5%); inter-island endemics (8.9%); circumtropical (16.2%); endemic (2.6%) and western Atlantic (1.0%). Species with long dispersal stages are more numerous, and the species composition strongly reflects the limited hard-substrate biomes available at lie Clipperton.

Vol. XXXIX: Supplement THE FESTIVUS Page 23 APPENDIX 1: AN ANNOTATED TAXONOMIC COMPILATION OF THE RECENT MOLLUSCAN FAUNA OF ILE 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 & Waren (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).

APPENDIX 3: A DOCUMENTED ZOOGEOGRAPHIC REVIEW OF THE MOLLUSCAN FAUNA OF ILE CLIPPERTON Appendix 3 categorizes the 191 identified Clipperton species into seven groups which define their zoogeographic affinities. The total number of identified taxa in each group is presented as a percentage of the 191 species: Eastern Pacific Species: 72 = 37.7% Indo-Pacific Emigrant Species at Clipperton Known to Occur on the Mainland (Oceanic Islands + Mainland): 23 = 12.0% Indo-Pacific Emigrant Species at Clipperton Known to Occur on the Oceanic Islands of the Tropical Eastern Pacific (Oceanic Islands only): 41=21.5% (Grand total for Indo-Pacific: 64 = 33.5%) Tropical Eastern Pacific Inter-Island Endemic Species: 17 = 8.9% Circumtropical Species that Occur at Clipperton: 31 = 16.2% Resident (Endemic) Species: 5 = 2.6% Western Atlantic Ocean Species Occurring in the Tropical Eastern Pacific: 2= 1.0% This review includes 43 new distribution records for the tropical eastern Pacific oceanic islands. The geographic entries are shown in bold and include: Islas Revillagigedo (24); Isladel Coco (14); Islade Malpelo (1); Islas Galapagos (3) and for mainland west America (1). The following taxa have been listed according to their faunal elements. The citations for geographic locality records following the species are believed to be the first record documented for each locality.
