New faces included Michael Hollmann from Germany and Larry MaCurda from the Guam Shell Club who stated that their members are interested in exchanging with our Club. Carole Hertz introduced speaker Tom Demere of the San Diego Natural History Museum's Paleontology Department who spoke on Pliocene mollusks of San Diego and their relation to Recent mollusks of the area. Tom Demere' s presentation took us back to remote geological times some five million years ago when ocean covered much of what we know as present-day San Diego County. Sharing with his audience some outstanding local marine fossil specimens, Tom traced the evolutionary history of local sea life. His slide presentation explored underlying fossil beds and the sedimentary rocks of the Pliocene Age. In sensational detail, he explained the geologic time scale and the ages of fossil mollusks in San Diego. Following this highly informative program, Tom treated Club members to a close-up examination of marine fossils including a handsome colony of the Pliocene scallop, Pecten (Patinopecten) healeyi Arnold. After the refreshment break with cookies provided by Carole Hertz and Suzanne Mathews, Bill Romer announced final arrangements for the December 3rd Club Christmas party. President Romer read the slate of officers for 1989. Nominations were then closed and the new officers elected unanimously (see masthead). A mini-program by Carole Hertz followed and took us on an entertaining tour of the 1988 WSM (Western Society of Malacologists) meeting held at Sonoma State University in July. Holly Hansen was the winner of the shell drawing and Larry Buck concluded the meeting by giving special recognition to Tony D'Attilio and Carole Hertz for their superb work on their joint project, "An Illustrated Catalogue of the Family Typhidae Cossmann, 1903."

The delightful aroma of steaming filet of sole and succulent prime ribs of beef drifted in the glittering atmosphere of the San Diego Room. All of us thoroughly savored the well-deserved frivolity and opportunity to chat with old friends. The tranquil waterfront view was spiced up with a slide show of vacation and underwater adventures, including pictures of Europe, sharks, and sea lions in kelp beds. Club President Bill Romer, who'll be greatly missed, bid members an affectionate farewell since he will be stationed in Long Beach. Passing the gavel to President- elect Larry Buck, Bill Laid that Larry will "make a great president," and Larry promised "new and exciting ideas" for the coming year. Thanks were given for a job well done by the 1988 board and hearty applause was given to the officers for 1989. The evening ended with the traditional Christmas shell exchange, the evening's biggest event, which resulted in the usual "oohs and aahs" as everyone unwrapped the treasures. Wayne Reed Vol. XXI (1): 1989 THE FESTIVUS Page 3 BIOLOGICAL WARFARE AT THE SEATTLE AQUARIUM BY ROLAND C. ANDERSON The Seattle Aquarium, Pier 59, Waterfront Park, Seattle, Washington 98101 Marine biofouling is defined as the settling of marine organisms from seawater onto an underwater man-made surface and growing there to the detriment in some way of that surface. The marine organisms may settle out of the water column as larvae onto the surface, swim or crawl onto the surface, or be chronically present on the surface. The biofouling may be animals or plants. Barnacles that grow on the bottom of ships are a well-known example of marine biofouling. A large ship may have as much as 300 tons of fouling marine organisms on its hull. Such animals settle there when the ship is in port and are then able to withstand the wash of the water underneath the ship while it is under way. Fouling on a ship’s hull will reduce speed, increase fuel consumption by up to 50%, and cause greater wear and tear on the ship's engines. More than a billion dollars is spent annually to control fouling on ships. While not in the billion dollar class, the Seattle Aquarium expends considerable time, money, and effort to control marine biofouling in the Aquarium's tanks, largely a battle against a ubiquitous brown diatom ( Chaetoceros sp.) that grows on the inside surface of the glass tanks, which obscures viewing of the exhibit animals and is unsightly on tank walls and backdrops. In smaller aquarium tanks this brown diatom scum yields to typical aquarium cleaning devices such as sponge sticks, brushes and razor scrapers and in larger tanks mechanical scrubbing and chlorination are the primary methods, but chlorine may be harmful to marine mammals and must be neutralized after it is used. In addition, large marine mammals may be difficult to isolate while their tank is being chlorinated, as is the case with 600 pound fur seals. Until recently some mammal tanks were left uncleaned for long periods of time to avoid contamination and disturbance of the marine mammals. During this time period the mammal biologist noticed some clean patches on the otherwise scum-covered walls. On closer inspection these clean patches were found to be the result of the work of small limpets, which had come in as larvae and settled onto the tank walls. Further experimentation with large herbivores such as abalones, sea urchins and chitons proved that these herbivores would eat the problem diatom but were large enough that the seals were able to pull the animals off the walls and kill them, so the mammal biologist reverted to the limpets. Upon measuring the diatom cover cleared by each limpet (approximately the size of a hand) he determined that it would take approxi- mately 3,000 to 5,000 limpets to keep the walls of the tank clean, so a large effort to collect the limpets began. Both staff and volunteers contributed to this epidemic of "limpet fever" collecting on low tides in the Puget Sound area, on lunch breaks, field trips, and family outings, as well as official collecting trips. Limpets collected and placed on the tank walls were Tectura scutum _, T. persona j Lottia pelta} and Acmaea mitra. After a year the results of this experimental biocontrol of the diatom scum are impressive (see Figures 1-3). It was found that the tank needed to be drained at least three times a week to keep the limpets alive, since they are intertidal creatures and need a certain exposure time; this experience is also borne out in the limpet tank in my invertebrate area. Unfortunately, this summer a new fur seal pup was born, so the tank was not drained on schedule, and most of the limpets died. The walls again became diatom-covered, but the pup will soon be old enough to begin draining the tank on schedule, and "limpet fever' at the Aquarium will begin once more. Page 4 THE FESTIVUS Vol .

Highland Avenue, Redlands, California 92373 Offshore islands have always been particularly appealing to me, especially those that are far-removed from the mainland. Isolated islands usually have a high degree of endemism in their flora and fauna. I have had the pleasure of being able to collect on many of the offshore islands of the tropical eastern Pacific, but it was not until February of this year that I was able to go the the Galapagos Islands. After many months of planning and several months of attempting to get collectors' permits, 24 of us found ourselves in Guayaquil, Ecuador on February 13, 1988, where we reconnoitered at the airport for our flight to the Galapagos. We had come from nine states, Mexico City, and San Jose, Costa Rica. Most of us were old friends from previous dives together at Cocos Island, Costa Rica. Because of the size of our group, we had to charter two vessels to accommodate us. We divided so that the "shark divers" would be on one boat and the "shell divers" on the other. The shark divers were interested mainly in underwater photography; and, of course, it is ob- vious what the shell divers were interested in. The Ecuadorian National Park Service had issued permits for only three of us to collect shells: Dr. Michel Montoya of San Jose, Costa Rica; Kirstie Kaiser of Park City, Utah; and me. Arbitrarily, we appointed the other collectors as our "assistants." As "assistants'' there were Captain Gene Everson of Louisville, Kentucky; Wayne Harland and his wife of Pompano Beach, Florida; and my wife, Urshi. Shelling was both good and bad. The water was sometimes frigid. The boat we were on, although only two years old, was badly in need of extensive repairs; out captain should have been a street sweeper. Enough said. Our shells have not yet all been identified; but, as of now, we have been able to add almost 50 species previously unknown in the Galapagos. One of the highlights of our trip was the privilege of visiting Jacqueline and Andre DeRoy in their home off of Academy Bay on Santa Cruz Island. The DeRoys have been very important in the development of knowledge of the molluscan fauna of the Figure 1.

Following our week in the Galapagos, Kirstie and I, along with several of the "shark divers," boarded the Victoria off Karlstad at Baltra Island, bound for Cocos Island.

AND HAUSTELLUM (MOLLUSCA: GASTROPODA: MURICIDAE) By W.F. Ponder and E.H. Vokes. 1988. Records of the Australian Museum, Supplement 8, 160 pages, copiously illustrated Published by: E. J . Brill/Robert Brown & Assoc., Postbus 9000, 2300 PA Leiden, Netherland Price: $48.00 seamail The long awaited appearance of the important treatise on the popular "Venus Comb Murex" has been well worth the wait. The species covered are only those in the Indo-West Pacific (that is excluding the eastern Pacific and the Atlantic, east and west). The well illustrated book is for the collector as well as the serious student and professional taxonomist. The valid species in this work number 55 and are treated at length with good descriptions, diagnoses and biogeographical data since many of the species have wide distribution. The species are divided into two main groups under Murex s.s. and Haustellum s.s.. Under the parameters, or taxonomic scheme adopted by the authors, there are some surprising changes constituting the shifting of species previously known as Murex s.s to Haustellum and vice ver^a in some cases. Since protoconchs are indicative only of species values and the radulae have no clear cut distinction in this scheme, one is left with having to accept the authors' conclusions concerning the importance of the characters selected for their generic arrangement. The keys provided are helpful for those curating a collection of considerable size. The soft parts of a number of species were studied and both described and illustrated in addition to the well done enlarged drawings of the protoconchs. The relatively few fossil species known are taxonomically treated and some speculative conclusions are drawn concerning their phylogenetic ancestral origins. Ten new species-group taxa are named and the generic treatment is expanded to include a new subgenus in Murex s.s.. However, for Haustellum the few species with a long history of assignment to this genus are treated as Haustellum s.s.. The remaining species, transferred from Murex , are simply called Haustellum. It would seem that since a subgeneric taxon has been used for one group, the major portion of those species shifted from Murex to Haustellum might have a subgeneric placement or be referred to as Haustellum s.l. , that is Haustellum only in the broad sense. However, do not let this small observation keep you from enjoying this altogether excellent work on the "Venus Comb Murex." Anthony D'Attilio Vol .

SHASKY 834 West Highland Avenue, Redlands, California 92373 We are indebted to Dr. Yves Finet, who is now with the Geneva Natural History Museum, for his 1985 paper titled "Preliminary Faunal List of the Marine Mollusks of the Galapagos Islands." In this paper he lists 593 verified species of mollusks and 190 species of "doubtful occurrence." From February 13-20 of this past year, Dr. Michel Montoya, Kirstie Kaiser, and I were granted permission to collect in the Galapagos. We were assisted by Captain Gene Everson and Mr. Wayne Harland. This report includes two species that Finet has added since 1985 (Finet 1987a and 1987b), adds two species that were in Finet* s doubtful occurrence list, one species in the Los Angeles County Museum of Natural History, and species collected by Wayne Harland, Kirstie Kaiser, and me that were not included in Finet' s list. I also add one specimen on which there is some controversy. [See discussion under "Omission" for Murexiella vittata (Broderip, 1833).] All specimens are in my collection unless otherwise noted. Finet lists 154 species endemic to the Galapagos (19.4% from "shallow water" and 6.6% from "deep water") which is equal to 26 percent of his total listing. In this paper I list six of these species, from my collection, that have been taken from out- side of the Galapagos and I add 36 non-endemic species to Finet 's list which reduces the endemic element to 23 percent. The percentages will undoubtedly drop as more taxa from other collections are reported. Certainly, additional species will also be added at a later date, after Montoya, Kaiser, and Everson complete their identifications. I also have a number of species that still await classification. Our success in finding so many previously unreported species is primarily due to two factors. The first is that we found a number of these while diving at night. The second is that during all of my daytime dives, I was shaking rocks or dead coral into my collecting bag, which produces all of the microscopic species that are listed. In the following list the taxa are generally placed in the order in which they are found in Keen (1971) including the species numbers assigned by Keen where applicable. Those species that do not have a Keen number that are preceded by I-P, are Indo-Pacific faunal taxa. ADDITIONAL RECORDS (All Panamic faunal constituents unless otherwise noted.

XXI (2): 1989 THE FESTIVUS Page 13 ON THE OCCURRENCE OF CHARONIA TRITONIS (LINNAEUS) IN THE EASTERN PACIFIC (RANELLIDAE: CYF1ATI INAE) BY WILLIAM K. EMERSON Department of Invertebrates, American Museum of Natural History, Central Park West at 79th Street, New York, New York 10024 This paper records the third verified occurrence of a living specimen of the Indo-Pacific giant triton, Charonia tritonis (Linnaeus, 1758), in eastern Pacific waters. The previous records were based on single specimens from Isla del Coco (Cocos Island) reported by Shasky (1983:144) and Montoya (1983:8) and from Isla Fernandina (Narborough Island) in the Galapagos Islands cited by Shasky (1983:144) and Finet (1985:18). An additional live-collected specimen from the Galapagos Archipelago was recently called to my attention. It was collected by Gayle Robinson on December 12, 1981 while SCUBA diving in about 60 feet (18 meters) of water approximately 3 miles (5 km) east of Academy Bay, Isla Santa Cruz (Indefatigable Island). This mature specimen, which is approximately 12 inches (30.5 cm), was observed feeding on a specimen of the asteroid sea star, Nidorellia3 according to Gary Robinson {in litt. , October 21, 1988). The shell (see Figure 1) and operculum were deposited in the Museum of the Charles Darwin Research Station at Academy Bay in May 1985. As reported by Shasky (1983:144), the only other known living specimen of this triton from Galapagan waters was obtained by diving at a depth of 7 feet (2.1 meters) near Punta Mangle, Fernandina Island, where it was found crawling on boulders. The shell (see Figures 2-3) and operculum were purchased from a local collector by Mrs. Carmen Angermeyer, a resident of Academy Bay, in August 1965. This specimen was estimated by her to have been 12 inches (30.5 cm) in length before the apex was lost to breakage. The lone specimen of this triton known from Cocos Island was found by SCUBA diving in 125 feet (42 meters) near Wafer Bay, in June 1981 and was donated by the collector to the Costa Rica Museum (Montoya, 1983:8). This specimen was said to measure about 8 inches (20.3 cm) in length. Charonia tritonis is widely distributed in the vast Indo-west Pacific faunal province. Populations are known to occur in the Indian Ocean, westward from the coast of Africa, and extend into the Pacific Basin, northward to southern Japan and the Hawaiian Islands and southward to Australia and New Zealand and perhaps as far to the southwest as Pitcairn Island (Beu, 1970:208; 1986:57). Populations which occur in the western Pacific Ocean closest to Cocos Island and the Galapagos Islands are known from the Line Islands (Kay, 1971:275) and the Tuamotu Archipelago (Couturier, 1907:147; Salvat and Rives, 1980:306), as well as the Society Islands (Dautzenberg and Bouge, 1933:253; Salvat and Rives, 1980:306). Rehder (1968:30) does not cite this taxon from the Marquesas Islands in his brief list of the most common and striking species he collected there. At my request, M.G. Harasewych searched without success the Smithsonian Institution holdings for records from the Marquesas Islands and Pitcairn Island, where Dr. Rehder also made extensive collections. Dr. Rehder subsequently informed me that he did not encounter this triton in the Marquesas Islands or at Pitcairn Island (pers. comm., October 26, 1988). Many species of the subfamily Cymatiinae have extensive geographical ranges resulting from the presence of a long-lived, planktotrophic larval stage, which permits passive dispersal over great distances and across deep-water barriers. The infrequent sighting of this Indo-Pacific species in eastern Pacific waters suggests that viable populations of this taxon are rarely encountered or have yet to become temporally established on the oceanic islands off the West Americas. This triton is Page 14 THE FESTIVUS Vol . XXI (2): 1989 not known from Clipperton Island, which has a molluscan fauna about equally divided between elements of the Panamic and Indo-west Pacific provinces (Emerson, 1967). The presence of this triton in the Galapagos Islands may reflect teleplanic larvae that were transported westward from populations in the Line Islands by the submerged Cromwell Current (Equatorial Undercurrent), whereas its occurrence at Cocos Island may represent larval dispersal westward by the Equatorial Countercurrent from the same sources (see Scheltema, 1988 and Zinsmeister and Emerson, 1979 for a discussion of the distributional role of the oceanic current patterns). Only five other representatives of the Cymatiinae that occur widely in the western Pacific are known in eastern Pacific waters. These are: 1, Cymatium (Monoplex) pileare (Linnaeus, 1758) [as macrodon (Valenciennes, 1832) Beu and Kay, 1988:210], from Clipperton Island, Cocos Island, the Galapagos Islands, and on the mainland from Baja California, Mexico to Panama; 2, C. (M.) pavthenopeum (Von Salis, 1793) [as pavthenopeum keenae (Beu, 1970), Beu and Kay, 1988:213], from the Galapagos Islands and Baja California, Mexico to Peru; 3, C. (m. ) aquatile (Reeve, 1844), known in the eastern Pacific on the basis of a single badly eroded beach specimen from Cocos Island (American Museum of Natural History 107015), fide Beu and Kay (1988:200); 4, C. (M. ) nicobavieum (Roeding, 1798), from Clipperton Island and Cocos Island (Emerson, 1978; Shasky, 1984, 1985); 5, C. (Guttuvnium) muvicatum (Roeding, 1798), from the Galapagos Islands and the Golfo de Montijo, Panama (Emerson, 1983). Figures 1-3 Specimens of Chavonia tvitonis from the Galapagos Islands.

XXI (2): 1989 THE FESTIVUS Page 17 THE FAMILY OMALOGYRIDAE IN THE TROPICAL EASTERN PACIFIC BY DONALD R. SHASKY 834 W. Highland Avenue, Redlands, California 92373 The genus Omalogyva Jeffreys, 1867, in the family Omalogyridae, contains species found in northern Europe, the Mediterranean, West Africa, locations on our Atlantic coast, and at least one species in the Indo-Pacif ic . Omalogy-ra japonica (Habe, 1972) has been reported from Hawaii to Japan. In 1983, I found a single specimen of a curious, minute, brown shell from Cocos Island, Costa Rica, that was about 0.5-0. 7 mm in diameter. Unfortunately, this shell was lost as it was being photo- graphed . Later, I found six specimens of the same species at Guaymas, Sonora, Mexico, but all but one of these were crushed or lost. In 1986, a second spe- cimen was found at Cocos Island, Costa Rica, and this past February, Kirstie Kaiser and I found many additional specimens at various col- lecting stations in the Galapagos and Cocos Islands (Figure 1). It seems to be an undescribed species. ACKNOWLEDGMENTS My thanks go to Bertram Draper who photographed the two specimens and to David K. Mulliner who prepared the black and white print from Bert's slide. Figure 1.

Norbert' s array of dramatic slides included arctic dives, hitchhiking parasites on jellyfish, and ocean sunfish (also in their larval stages) in kelp forests. The skilled photographer also mentioned how, while filming a shark from above, looking down onto its darkly colored back, the animal will blend in with the dark water or reef below. He noted the opposite is true if your perspective is looking upward, since the underside of the shark is light colored. Members were also treated to photographic subjects which dwell at depths of 500 to 6,000 meters many witn long, protrusible jaws and long, slender needlelike teeth. Just before the break, Larry, anxious to find new ways of improving or adding to Club activities, circulated a questionaire and members checked off the kinds of activities they would like to see in the future. During the break, longer than in the past, members had the opportunity to circulate and view a fine assortment of shell specimens brought in by Club members. Ihe typhid shells will be the shells of the month for the February meeting. At the business portion of the meeting Larry announced the date for the Auction/ Potluck. It will be Saturday, April 15th and Larry called for donations to be brought to the next meeting. 6 The cookies were provided by Larry Buck and Carole Hertz and Linda La Grange was the winner of the door prize. Wayne Reed Vol. XXI (2) : 1989 THE FESTIVUS Page 19 IN MEMO R I AM BARBARA GOOD 1922-1988 We report with regret the passing on December 25th of Barbara Good, a friend and active member of the San Diego Shell Club for the past twenty-two years. Barbara was an avid collector who corresponded and exchanged with collectors world- wide and whose special interest was in minute molluscan species. She could often be seen on trips going carefully through the kelp holdfasts and the roots of the washed- in surf grass to find the tiny species embedded there. She was a participating member of the San Diego Shell Club (treasurer, 1963', contributor to The Festivus); the American Malacological Union-Pacific Division (secretary, 1965) and the Western Society of Malacologists and a willing worker in all of them. After receiving her Masters Degree at U.C. Berkeley in 1944, she met and married Frank Good. After the war they settled in San Diego where he practiced law and she was, for a time, a social worker. Barbara is survived by her son Rick, his wife Jane, and her three grandchildren. Our sympathy is extended to the family. CHARLENE NEEB -1988 Word has reached us that Charlene Neeb, a charter member of the San Diego Shell Club who was active in Club activities through the early 1970s, passed away some time in the latter part of 1988. In an early article in The Festivus (April 1972) Charlene reminisced about observing and collecting mollusks in San Diego in the 50s and 60s. In a quote from that article which follows, Charlene noted that at the beach near the pier in Del Mar (they had one then) in 1959, "The [Cypraea] spadicea were so thick we were picking them up and putting them in our skirts - we wore dresses then - to put them back so the kids couldn't get them. The kids were throwing them around." Charlene had been ill for many years. CLUB NEWS DUES ARE DUE If you have not already done so, it is time to renew your membership for 1989.

XXI (3) : 1989 BOOK NtWS THE AMBER FOREST: BEAUTY AND BIOLOGY OF CALIFORNIA'S SUBMARINE FORESTS By: Ronald H. McPeak, Dale A. Glantz, and Carole R. Shaw. 1988. Publisher: Watersport Publishing Inc., San Diego, California 144 pages, 125 plates. Price: $24.95 softbound, $35.95 hardbound At last, the long-awaited book on the kelp beds and their inhabitants has arrived. Aptly, the book by Club member Ronald H. McPeak and coauthors Dale A. Glantz and Carole R. Shaw is entitled THE AMBER FOREST: BEAUTY AND BIOLOGY OF CALIFORNIA'S SUBMARINE FORESTS. It contains 125 plates, mostly colored, within its 144 pages. This book is about the giant amber-colored seaweed, Maovocystis pyrifera. , commonly called giant kelp. Starting with an overview of the localities at which kelp forests occur the introduction continues with a brief discussion of the historical importance of kelp. Sections follow on the life cycle and growth of kelp and the ever-changing appearance of the forest as the plants are exposed to the forces of nature. The forest as a habitat is divided into sections on the holdfasts, the midwater fronds, and the surface canopy. Interspersed throughout the text are magnificent underwater color photographs of the forest and its inhabitants as well as surface photography of the kelp forests and the adjacent coastlines. The book is done in quality heavy, glossy stock and the photography alone is worth the price. Most of the photographs were taken by authors McPeak and Glantz, but there are also photographs by other well-known San Diego underwater photographers. The text concludes with chapters on the harvesting of the kelp forests, fishing and diving in the "forest," conservation, and education. The book is written for a wide audience and will be enjoyed by the layman whether as amateur scientist, diver or as an appreciator of the beauty of nature. The type is large and easy to read and the well-written text is easily understood with a wealth of information packed into the relatively small volume. The inhabitants of the Amber Forest and transients that pass through it range in size from microscopic bryozoans to gigantic mammals such as the gray whale. They include birds, fishes, mammals and invertebrates. They are beautifully captured in color photographs and it is difficult to pick favorites. This reviewer's personal choices are closeup shots of an otter, an elephant seal and a proliferating sea anemone ( Epiaotis prolifera) . I found only a few plates which detracted from the tone of the book. One was of a posed red abalone shell ( Haliotis rufesoens ) on a stretch of wet sand. The others were a series of three plates on the commercial products made from kelp, which I believe diminished rather than enhanced the overall image of this beautiful volume.

MYERS Department of Marine Invertebrates, San Diego Natural History Museum P.O. Box 1390, San Diego, California 92112 Between March and September, 1988, 30 immature specimens of Astraea turbaniaa (Dali, 1910:134-135) ranging in size from 53.4 to 85.7 mm were collected by John Myers using SCUBA at Pt. Loma, San Diego, California and Bird Rock, La Jolla, California from a depth of 25 meters (Figures 1-3). Two specimens have been deposited in the San Diego Natural History Museum (SDNHM 93366). This species is not usually found in coastal San Diego waters, and is more commonly found on offshore islands along the west coast of the Baja California peninsula, Mexico. Figures 1 and 2. Astraea turbaniaa (Dali, 1910). (1) Immature specimen showing double carinae. B.W. Myers collection. Specimen from Pt. Loma, San Diego, California. 66.o mm height/86.3 mm width. (2) Operculum of A. turbaniaa showing subcircular shape compared to the pointed oval shape of A. undosa. Also shows the ribs curving around the anterior end instead of terminating anteriorly as in A. undosa. Same specimen as Figure 1. Photos: D.K. Mulliner Page 23 THE FESTIVUS Vol . XXI (3) : 1989 McLean (1971) noted that A. turhanica differs from the more common A. undosa (Wood, 1828) in having two strong peripheral ridges rather than one and the lowermost ridge of the operculum is curved and nearly lacking spines while that of A. undosa is uncurved and spiny. A. undosa is found along the Pacific coast of North America from Pt. Conception to Asuncion Island, central Baja California (McLean, 1970). The A. turhanica specimens from Pt. Loma and Bird Rock were found in association with A. undosa on the same substrate and at the same depth. Stohler (1959) detailed the differences between A. undosa and A. rupicollina Stohler, 1959 (Figure 4) and A. petrothauma Berry, 1940 (Figure 5). McLean (1970) placed A. petrothauma and A. rupicollina into the synonymy of A. turhanica. Figure 3. A. turhanica 3 Holotype, USNM 111242.

Berry collection 7701 (now at Santa Barbara Museum of Natural History) . Synonym of A. turhanica. Lower Pleistocene "Hilltop Quarry," San Pedro, California. 49.3 mm height, 39.3 mm diameter. One other species in this complex, A. gradata Grant and Gale, 1931, appears closely related to A. turhanica. The holotype (SDNHM 286, Paleontology collection) (Figure 6) is from the Middle Pliocene, southeast of Pico Canyon, Los Angeles County. The operculum (paratype SDNHM 287, Paleontology collection) (Figure 7) was found separately and is from the Pliocene of Holser Canyon, north of Santa Clara Valley, Los Angeles County. The operculum differs from that of A. turhanica in possessing only two ribs, instead of three; the ribs are thicker and more robust, and there is a knob or thickening at the apex. A. turhanica appears to be highly variable in its height to width ratio of the shell and in the strength of the axial ribs. In some specimens the whorls are Vol. XXI (3) : 1989 THE FESTIVUS Page 24 tabulate. The double carinae often become less prominent as specimens reach maximum size. Several specimens in the Los Angeles County Museum of Natural History collection measure over 160 mm in height. The holotype of A. vupicollina (USNM 610331) (Figure 4) is recorded at 163 mm height. A paratype of A. vupieollina (SDNHM 10855) measures 141.5 mm height and 124.5 mm width. An operculum of A. petvothauma of 63. > mm (Figure 8) was obviously meant for a much larger shell and according to Berry indicates that at maturity the species greatly exceeds the size of the specimens he foi *^d (Figure 8). Figures 6-8. (6) A. gvadata Grant and Gale, 1931. Holotype SDNHM 286 Paleontology collection. Type locality Middle Pliocene between Pico Canyon and Fernando Pass, Los Angeles County. 65 mm diameter.

After Berry (1940) who noted that it was for a sheli of a much larger size than any he found. Twenty-two lots in the Los Angeles County Museum of Natural History collection establish A. tuvbaniea from Coronado del Medio, Los Coronados, Mexico (32°25.5'N) (LACM 71-98), and south at the following islands along the west coast of the Baja California peninsula: San Martin, San Geronimo, Guadalupe, San Benito, Cedros, Natividad, and on the mainland peninsula at Punta Rompiente, Cabo Thurloe and Punta de San Pablo (27o12'30"N) (LACM 71-178). The southernmost range of this species was established by Dali (1910) at Magdalena Bay, the type locality. The specimens recently collected at Pt . Loma and Bird Rock, California extend the known distribution of A. tuvbaniea north the short distance of approximately 50 kilometers, but the main- land record for this species is extended approximately 600 kilometers north. Little diving has been done along this stretch of the coast of Baja California and in the future, specimens of A. tuvbaniea may be found in new localities from Magdalena Bay to San Diego. The species has also been found in kitchen middens at Santa Barbara Island, Ventura County, California (LACM 45221) and as a fossil in the Lower Pleistocene, "Hilltop Quarry," San Pedro, Los Angeles County, California (Berry, 1940), type locality of A. petvothauma. This study was carried out at the San Diego Natural History Museum, and I wish to thank the Museum for the use of its molluscan collection and library as well as the use of equipment and facilities. 6 A- ACKNOWLEDGMENTS Page 25 THE FESTIVUS Vol. XXI (3) : 1989 I also wish to thank J.H. McLean of the Los Angeles County' Museum of Natural History for reviewing this paper and for the opportunity to study specimens of A. turbanica in the Museum collection. I further thank David K. Mulliner for taking the photographs of A. turbanioa and lastly John Myers for his important contribution to this paper — the discovery of A. turbanica along our coast at Pt. Loma and Bird Rock.

A NOTE ON THE DISTRIBUTION OF FAVARTIA R0SAF1IAE D ' ATT I LI 0 AND MYERS, 1985 ANTHONY D’ATTILIO 2415 29th Street, San Diego, California 92104 In examining the specimens of Favartia rosamiae D’Attilio and Myers, 1985, in the Don Pisor collection, I noted a specimen collected by Mr. Pisor at Vava'u, Tonga in June 1986. This indicates that this small species, known from 75 to 100 meters in the Philippine Islands and Okinawa, is most likely more widely distributed than previously thought from the description of the type material. Mr. Pisor has kindly donated this specimen to the Marine Invertebrate collection (SDNHM 93367) of the San Diego Natural History Museum. c Vol . XXI (3) : 1989 THE FESTIVUS Page 26 A TRIP TO PUERTO ESCONDIDO LARRY BUCK 2534 Via Pisa, Del Mar, California 92014 In December 1988, a group from San Diego including Margaret and Dave Mulliner, Nola Michel and I traveled to Puerto Escondido, Baja California Sur , Mexico for a two week shell collecting trip. We encountered a mixture of weather conditions, but the water for diving/collecting was consistently good. The water temperature was in the low seventies, underwater visibility was usually over 30 feet, and we found some unusually good shells. My ability to locate and identify bivalves by their siphons took a quantum leap on this trip. It progressed from blankly staring at the bottom and seeing nothing to, "Wow! I know what that is." Baja has an abundance of magnificent bivalves. I found a sizable number of Spondylus prineeps Broderip, 1833, to choose from. My best were clusters of two and three and a gnarly old, but beautiful, monster. I also found large beautiful Periglypta multioostata (Sowerby, 1835); Ventrieolaria isocardia (Verrill, 1870); Chlamys lowei (Hertlein, 1935); Pecten vogdesi Arnold, 1906 (uncommon as a result of overfishing by the Mexicans); Lyropeoten subnodosus (Sowerby, 1835) with six Chama venosa Reeve, 1847, attached to its dorsum; Semete yunonia (Verrill, 1870); Megapitaria aurantiaoa (Sowerby, 1831); Pinna rugosa Sowerby, 1835; Cardita orassioostata (Sowerby, 1825); Cardita megastropha (Gray-, 1825); several beautiful color variations of Papyridea aspersa (Sowerby, 1833) plus an incredibly large cluster of Ostrea fisheri Dali, 1914, with different shades of browns and purples. This last species is probably the most common large bivalve in this area of the Gulf and one of the most attractive when a good specimen is cleaned properly. Besides being lucky in finding lobsters and halibut, this trip also provided some of my more exciting gastropod finds including three Pterynotus pinniger (Broderip, 1833) (Figures 1 and 2) which was my main objective on this trip. I found Figures 1 and 2. Pterynotus pinniger (Broderip, 1833). Length; 63.2 mm (1) apertural view (2) dorsal view. Page 27 Vol. XXI (3) : 1989 - THE FESTIVUS several Muricanthus prinoeps (Broderjip, 1833 ) in clean condition; Xenophora robusta Verrill, 1870, dead but in good condition; several Oliva species including Oliva porphyria Linne, 1758; 0. spioata' Rod^ng., $’798; and several 0. keleontina Duclos, 1835. I also found Terebra omata G ray, 1834 (common on clean sand at 100 feet); a 360 mm perfect Fasciolaria prinoeps Sowerby, 1825 (my best to date); Cypraecassis coaratata (Sowerby, 1825); Cypraea annettae Dali, 1909; dead C. robertsi (Hidalgo, 1906) and C. oerpi^^^c^' Wiener, 1843, and a dozen species I still have not identified including cot^e*^Snd several "outrageous" bryozoan colonies with their hermit crab hosts. « C %:'• - .. ► As a result of finds, on this trip I have found several possible world record- size shells, the siz'es. of •'t^’hich I have submitted to The Lost Operculum Club and the "World Size Records" supplement of Wagner and Abbott's Standard Catalog of Shells . These include an enormous 267 mm Malea ringens (Swainson, 1822); a 100.4 mm Ventricolaria isooardia (Verrill, 1870) and a huge 181 mm Cymatium parthenopevm keenae (Beu, 1970). I've found about a dozen of this impressive species now and each one I find always seems to be larger tnan the last. (Dave Mulliner is planning an article on C. parthenopevm keenae for a future issue of The Festivus.) Hopefully, we will soon return to Puerto Escondido and I'll continue my education on bivalve siphons and see what else my luck brings. CLUB NEWS THE AUCTION/ POTLUCK The Club's annual Auction/Potluck will be held on April 15th. Wes Farmer has graciously offered his condominium Club House for this fun-filled event again this year. (A map will be included in the April issue of The Festivus.) Your quality specimen shells are much needed to make this auction a success.

Box 1192 Burlington, MA 01803) In 1980 Kay Vaught published her useful 93-page work, AN OUTLINE OF CLASSIFICATION OF LIVING SHELLED MARINE MOLLUSKS. Now this author has greatly expanded her original work in her new CLASSIFICATION which includes a systematic listing of the supraspecif ic names in all the living Mollusca — terrestrial, fresh- water and marine. This new book, a result of ten years of careful research, lists over 15,300 named taxa arranged in systematic order based on current information. A two-page addenda of taxa not included in the outline precedes the 44-page index to all the listed names and the major references consulted for each superfamily are located throughout the CLASSIFICATION in the sections to which they apply. The author has consulted widely with professional malacologists in preparing this work which will certainly become a necessary tool for the advanced amateur and the professional malacologist in curating their collections. While differences of opinion concerning some interpretations are to be expected in such an ambitious work, this reviewer agrees wholeheartedly with the following statement quoted from the Editorial Preface. "We can now thank an enthusiastic amateur malacologist for under- taking this useful and enormous compilation.... The field of malacology and the community of private mollusk collectors owe Kay Vaught a debt for her contribution and praises for her accomplishment." Carole M.

MYERS and ANTHONY D'ATTILIO Department of Marine Invertebrates, San Diego Natural History Museum, San Diego, California 92112 2415 29th Street San Diego, California 92104 Recently a well preserved specimen of HomaZocantha scorpiio (Linne, 1758) collected in tangle nets off Bohol Island, Cebu, Philippines at a depth of 75 to 100 m, with four digitations on the outer lip, was figured by Foster and Glass (1984), and subsequently borrowed for study. This unusual specimen prompted our re-examination of the species (Figure 1). Figure 1. Homalooantha scorpzo (Linne', 1758). Dorsal and ventral views of specimen from Bohol Island, Cebu, Philippines collected in tangle nets, 75 to 100 m. Coll, of R. Foster and C. Glass. 31.5 mm Photos: D. Mulliner Murex scorpzo was described by Linne in 1758:747 in the 10th edition of the Systema Naturae. His brief description, "M. testa quadrifariam frondosa, spira capitata, cauda truncata," was supplemented by references to three figures. The first figure he referred to was Rumphius (tab. 26, fig. D) . Rumphius published "D'Amboinche Rariteitkamer . . . " in 1705 and in "Thesaurus imaginum Piscium Testaceorum. . . " published in 1711, the plates from D’Amboinche Rariteitkamer were Page 31 THE FESTIVUS Vol . XX 1 ( 4 ) : 1989 reprinted with explanations (Boss, 1988). The San Diego Natural History Museum's copy of Rumphius* Thesaurus imaginum Piscium . . . is dated 1739. This figure anpears reversed as do most of the figures on that tablet. The specimen is lying on its side with the aperture face down. The shell is slender with an excavated spire, but it is not clear whether there are four or five digitations on the outer lip (Figure 2). The second figure reference was Gualtieri (1742:tab. 37, fig. M) (Figure 3). This figure has a large bulbous body whorl and a conical spire, unlike Homalocantha Scorpio. It has four palmate digitations on the outer lip. The third figure was from D'Argenville (1742: tab. 19, fig. D) . The San Diego Natural History Museum's copy is a later edition and H. Scorpio is figured on tab. 36, fig. G-3 (Figure 4). This figure has four digitations on the outer lip and a spire somewhat constricted and excavated . Figure 2. H. Scorpio , Figure 3. H. Scorpio, after after Rumphius (1711, Gualtieri (1742: tab. 37, fig. M) tab. 26, fig. D) Figure 4. H. Scorpio, after D'Argenville (1742, tab. 36, fig. G-3) In the 12th edition of the Systema Naturae (1767:1215), Linne added Seba (1734-65: tab. 77, figs. 13-16) as a reference (Figure 5). These figures are similar to D'Argenville with four digitations on the outer lip. Seba alone shows both an apertural and dorsal view of a specimen and we can count five varices. Two other specimens shown are dorsal views and both have four digitations on the lip. All the figure references supplied by Linne have four palmate digitations on the labial lip. The specimens referred to H. Scorpio by recent authors (Fair, 1976; Vol . XXI (4) : 1989 THE FESTIVUS Page 32 Radwin and D'Attilio, 1976; Springsteen and Leobrera, 1986) have five digitations on the outer lip. Radwin and D’Attilio (1976) state that specimens from old (19th century) collections have four rather than five digitations. Specimens of H. Scorpio borrowed from the American Museum of Natural History, all from old collections formed more than 100 years ago, have four digitations instead of five.

Constable collection Philippine Islands, ex R.L. Stuart collection In addition to the variability in the number of digitations, further study of specimens in the San Diego Natural History Museum and the Don Pisor collection as well as the many specimens borrowed from the American Museum of Natural History and the Academy of Natural Sciences of Philadelphia showed the spire to be moderately high and deeply excavated or low with only moderate excavation (Figures 6 and 7). Figure 6. H. Scorpio, ventral view of Figure 7. H. Scorpio, ventral view of specimen in the collection of D. Pisor. specimen in the collection of D. Pisor. Photo: D. Mulliner Photo: D. Mulliner The body whorl may be broad and robust or slender and delicate (Figures 8 and 9). The color can be black, brown or white. We could find no consistent differences to separate specimens with four digitations on the outer lip from those with five digitations or those with a high, excavated spire from those with a low moderately excavated spire. Perhaps this unusual specimen from Bohol Island, Cebu is a deep water form of the species. See the article on this specimen by A. D'Attilio in this issue. Page 33 THE FESTIVUS Vol .

Mulliner Radwin and D'Attilio (1976) placed Murex varicosus Sowerby (1834, pi. 65, fig. 49) in the synonymy of Homalocantha Scorpio 3 but Sowerby' s figure does not resemble H. Scorpio. Further, Murex varicosus Sowerby is a homonym of Brocchi (1814) and Renier (1804). Holten (1802) also used this taxon (Vokes, 1971). Fair (1976) placed M. Varicosus Sowerby in the synonymy of M. digitatus Sowerby, 1841 and that seems to be the correct placement; with the name M. varicosus preoccupied, M. digitatus would be the next available name. The placement of M. digitatus in the synonymy of Homalocantha Scorpio by Radwin and D'Attilio as well as their placement of Murex fauroti Jousseaume, 1888, is now considered in error. Fair (1976, fig. 252, 252a) illustrates the type of M fauroti and it appears distinct from Homalocantha Scorpio. ACKNOWLEDGMENTS We wish to thank the San Diego Natural History Museum for use of the scientific library as well as the molluscan collection and other facilities and equipment of the Department of Marine Invertebrates. We also wish to thank Robert Foster and Charles Glass of Santa Barbara, California for the loan of their unusual specimen of Homalocantha Scorpio. Donald Pisor of San Diego, California kindly lent several specimens of H. scorpio from his personal collection for this study. The American Museum of Natural History and the Academy of Natural Sciences of Philadelphia kindly lent us a number of specimens of H. Scorpio from their extensive collections. The photography in this paper was done by David K. Mulliner of San Diego for which we thank him. Vol . XXI (4): 1989 THE FESTIVUS Page 34 LITERATURE CITED D' ARGENVILLE, A.J. 1742.

XXI (4): 1989 ILLUSTRATIONS OF A DEEP WATER FORM OF HOMALOCANTHA SCORPIO (LINNE, 1758) ANTHONY D' ATT I L 10 2415 29th Street, San Diego, California 92104 A most unusually well-preserved specimen of Homalocantha Scorpio (Linne, 1758) was studied through the courtesy of Robert Foster of Santa Barbara, California. This 31.5 mm specimen with five whorls was collected south of Bohol Island, P.I. in tangle nets in approximately 75 to 100 meters and was illustrated by Foster and Glass (1984,12(4) :54, fig. 12). Further illustrations are provided herein by means of camera lucida drawings at 25 to 50 times enlargement through a "Wild" microscope. These enlarged drawings show the protoconch, details of the shell and the spinose formations. LITERATURE CITED FOSTER, R. and C. GLASS 1984. Homalocantha a pictorial addendum. 53-55, 20 figs.

Highland Avenue, Phoenix, Arizona 85018 Phenaoolepas puntarene (Morch, 1860) was reported from 183 meters (600 feet) off the northwestern end of Isla Smith (113°34,W; 29°6'N), Bahia de los Angeles, Gulf of California, Mexico by Skoglund (1988, fig. 9). Dr. James H. McLean of the Los Angeles County Museum of Natural History wrote to say that the figured shell resembled Iothia lindbergi McLean, 1985. The specimens were sent to him. Dr. McLean's work with the radulae confirmed his identification. This extends the known southern range of Iothia lindbergi from Isla Benito, off the outer coast of Baja California into the Gulf of California at Isla Smith. The names on figure 9 and in the text on page 114 (Skoglund, 1988) should be corrected from Phenaoolepas puntarene (Morch, 1860) to Iothia lindbergi McLean, 1985.

VOKES, 1988 In a recent paper, "Muricidae (Mollusca: Gastropoda) of the Esmeraldas Beds, Northwestern Ecuador" [Tulane Stud. Geol. Paleo. 21(l):l-50, July 20, 1988] Dr. E.H. Vokes described the species Murex ( ?Haustellum) ruthae [pp. 18-21, pi. 1, figs. 4,5; pi. 2, figs. 1,2] as the Gulf of California species long known as Murex elenensis Dali, 1909. According to Dr. Vokes, M. elenensis comes from Santa Elena Bay, Ecuador (type locality) to as far north as the Gulf of Nicoya. The northern form which "appears to be confined to the Gulf of California, usually in depths of 5 to 10 meters" is named M. ruthae in honor of the late Ruth Purdy, who had been a longtime member of the San Diego Shell Club. Dr. Vokes considers that M. ruthae 3 found in the Esmeraldas beds is "the ancestral form which has now retreated to the Gulf of California. " In her discussion, Dr. Vokes contrasts the two species with M. ruthae having a heavier larger shell with coarser sculpture and two, rarely three, intervarical nodes and longer, heavier, straighter spines which extend down the siphonal canal. M. elenensis has three to four intervarical nodes and the varices are more deeply excavated adaperturally . Dr. Vokes considers plate 11, figure 13 in Radwin and D'Attilio's 1976 "Murex Shells of the World" to be M. ruthae. Carole M. Hertz Vol .

Don't miss it!! FROM THE MINUTES - SAN DIEGO SHELL CLUB MEETING - FEBRUARY 16, 1989 The meeting was called to order at 7:35 P.M. by President Larry Buck. Following introductions, Ron McPeak presented the speakers for the evening, Ken and Marge Lindahl of The Golden Shell shop on Balboa Island who gave a fascinating slide show of their recent trip to Australia, New Zealand, Gauadalcanal and New Guinea. Following this, Tony D'Attilio gave a short but very interesting talk on the Typhidae. Ron McPeak announced that his new book, "The Amber Forest" was finally out. Following the refreshment break, Kim Hutsell described the new Club pin that will soon be available and his wife Linda, the Club historian, requested infor- mation and photos about the Club from 1980 to the present. Jules Hertz shared items of interest in the new books and periodicals that have been added to the Club library and Larry announced some important dates that are coming up: Club Auction on April 15th, shell bazaar at Larry's home on August 20th, and the Christmas party on December 2nd. Larry also circulated a list for possible hosts for a progressive dinner party contemplated for later this year.

Maria Goldstein brought the delicious cupcakes for the break and Ken Lindahl, our speaker, won the door prize. Rick Negus FROM THE MINUTES - SAND DIEGO SHELL CLUB MEETING - MARCH 16, 1989 Larry Buck welcomed members and guests including the Club's youngest and newest member, Dillon Valli born to Adrian and Sherry on February 8th. Bob Yin introduced our speaker of the evening, Ron McPeak, who shared his rich knowledge of the world beneath the kelp in his outstanding program, THE AMBER FOREST. based on.a book by Ron McPeak, Dale Giantz and Carole R. Shaw. Ron took us on a marvelous slide show voyage within the mysterious kelp forest. The visual experience revealed the fierce intensity of kelp growth which spreads its living carpet over great areas of our local ocean. Ron spoke about the forming of new kelp and mentioned that up to 175 species of animals have been recorded living in one kelp holdfast. There were breathtaking photographs of about 2000 pectens attached to a kelp stalk, and 200-300 meters of red and purple urchins grazing on the dense canopies! Ron has managed to catch on film the unbelievably lavish fruitfulness of marine life forms within the amber forest. His book was available to interested members during the coffee break. Ron's program was followed by Dave Mulliner's slides of the 1988 Christmas party. Thanks to Dave, the good memories returned and the slides will go into the Club library where members can check them our to show at home or to make duplicates. Jules Hertz shared some recent publications in the Club library and Carole Hertz reported that we have already recovered half the cost of the latest supplement. Linda Hutsell reported on the progress of the historian's books and members were invited to sign up for a shell photography seminar to be hosted by Dave Mulliner at his home at 1:00 PM on April 2nd. A field trip to San Felipe is planned for the April 5th low tides and another on field trip on Apri1 22nd to see Bod Foster's outstanding shell collection.

XXI (5): 1989 CLUB NEWS THE ANNUAL AUCTION/POTLUCK The annual Auction/Potluck on Saturday evening April 15th was a rip-roaring success. The clubhouse at Wes Farmer's condominium bulged with members and guests and the atmosphere was one of heightened excitement as members, armed with their auction lists, studied the specimen shells to be sold and the vast amount of silent auction material which filled the adjacent room of the clubhouse. Attendees were kept busy checking on silent auction items they hoped to win later that evening, while examining the voice auction specimens. The potluck dinner offerings preceding the main event were delicious — and bountiful and along with Dave’s punch and soft drinks, everyone was in a mellow mood — perfect for bidding. Soon after 8:00 P.M., auctioneers Carole Hertz and Larry Buck were facing the spirited group who had a most beautiful selection of shells on which to bid. And bid they did! The shells for auction had never been better and, in addition, a Tony D'Attilio drawing and several fine books were on the block. With just a short break mid-evening, the weary bidders were not finished their work until just after mid- night. It was great fun, very tasty, and the biggest profits yet. Our special thanks to Wes Farmer for hosting the Auction — the third Club party he has held in less than two years!

Box 1390, Los Angeles County Museum of Natural History San Diego, California 92112 900 Exposition Blvd., Los Angeles, California 90007 In our study of the family Vitrinellidae in the Gemmell collection from the San Felipe area, Baja California Norte, Mexico, we have come upon many interesting problems. None proved more puzzling than the five Gemmell specimens which we con- sidered conspecific with Cyclostremiscus nodosus of Pilsbry and Olsson, 1952, ( not C. nodosus Carpenter, 1857). Figure la-c illustrates one of these specimens. Figure la-c. Turbo fluotuosus Wood, 1828. Juvenile, 1.4 mm 'max. c!iam. Specimen in Gemmell collection we had identified as CycZostremiscus nodosus of Pilsbry & Olsson, 1952 ( non C. nodosus Carpenter, 1857). Pilsbry and Olsson, (1952) figured what they considered to be a second specimen of CyoZostremisous nodosus (Carpenter, 1857) found in the Carpenter collection in the Redpath Museum, McGill University, Montreal^ Canada (cat. no. 3977) (Figure 2). However, Carpenter (1857) stated that he had only one immature specimen from Mazatlan (Figure 3). It is our conclusion, based on examination of the original Figure 2. C. nodosus of Pilsbry & Olsson, 1952. Figure 3. C. nodosus (Carpenter, 1857). 1.3 mm max. diam. After Pilsbry & Olsson, 1952.

XXI (5): 1989 figures (Figures 2 and 3) and descriptions, that the two specimens are significantly different. Carpenter's specimen bears evenly spaced nodes on the upper keel, whereas the Pilsbry and Olsson specimen has only three large nodes on the final portion of the upper keel. The Gemmell specimens with a maximum diameter of 1.4 mm (Figure la-c) differ by only 0.1 mm from the Pilsbry and Olsson specimen which has a maximum diameter of 1.3 mm (Figure 2). The Gemmell specimen and the Pilsbry and Olsson specimen have 2 3/4 whorls, are widely umbilicate, and both show sculpture of prominent nodes on the final portion of the "body whorl." At this point we decided that the Pilsbry and Olsson specimen might need a new name and we began re-examining the Gemmell material with this in mind. On placing these specimens under the microscope at high magnification (25X) for another look, we observed that one 1.2 mm shell had several faint spots of color. This was a surprise, since vitrinellids are glassy to opaque-white. We now had to reconsider the placement of these five specimens. We considered as alternatives the archaeogastropod families Trochidae, Liotiidae and Turbinidae and it was in the Turbinidae that we found our answer. A Gemmell collection growth series of 29 specimens of Turbo fluotuosus Wood, 1828, from 1.5 to 2.4 mm maximum diameter was studied and revealed the progression from vitrinellif orm shape to that of Turbinidae (Figures 4-6). The juvenile Turbo fluotuosus shell becomes imperforate (Figure 6), the large nodes disappear, the flattened whorls give way to a rounded profile and color becomes more evident (Figure 5). The five Gemmell specimens thought to be vitrinellids are juvenile Turbo fluotuosus 3 which species has a discontinuous distribution from Cedros Island on the outer coast of Baja California through the Gulf and south to Banderas Bay and the Tres Marias Islands; and from La Plata Island, Ecuador to Paita, Peru (McLean in Keen. 1971).

Mulliner Vol . XXI (5): 1989 THE FESTIVUS Page 44 In basal view, the Gemmell specimens (Figure 1) do not agree with the Pilsbry and Olsson specimen (Figure 2) because "part of the penultimate whorl is exposed" in the Pilsbry and Olsson specimen but not in the Gemmell material (McLean, written comm.)* In the opinion of Dr. James H. McLean, of the Los Angeles County Museum of Natural History, the Pilsbry and Olsson specimen is a juvenile Astraea although both Astraea and Turbo "are initially bicarinate and flat spired." However, Dr. McLean notes that "in P & 0's figure, in basal view, part of the penultimate whorl is exposed and the peripheral projections of the uppermost cord are more acute." We confirmed this by examining a growth series of five specimens of juvenile Astraea undosa (Wood, 1828) in the B.W. Myers collection. The specimens, from 1.7 to 3.7 mm maximum diameter, Figure 6. Turbo fluctuosus 3 base of which exhibited the aforementioned largest specimen in Figure 5 (2.4 mm) showing features also showed an open umbilicus imperforate base. Photo: D. Mulliner until reaching a diameter of 3.0 mm (Figure 7a-d). Figure 7a-d. Astraea undosa (Wood, 1828).

Myers collection showing the flat spired bicarinate shell and enlarged projections. The basal view of this specimen in (c) shows the beginning of closure of the umbilicus. It is our conclusion that the Gemmell specimens under discussion are juvenile Turbo fluctuosus and that the supposed Carpenter specimen figured by Pilsbry and Olsson (1952) as Cyclostremlscus nodosus is not a vitrinellid but a turbinid, most likely an Astraea.

XXI(5): 1989 THE FEST1VUS Page 46 A FURTHER NOTE ON THE TAXONOMY OF MU REX PERMAESTUS HEDLEY, 1915, A JUNIOR SYNONYM OF MU REX CAPUCINUS LAMARCK, 1822 ANTHONY D'ATTILIO 2415 29th Street, San Diego, California 92104 In a previous paper (D'Attilio, 1988) I considered Murex permaestus Heciley, 1915, a junior synonym of Murex eapuoinus Lamarck, 1822, and concluded that on the basis of shell morphology and radula, the placement of this species remained in question. In a recent letter, Dr. Emily H. Vokes brought to my attention that a generic taxon had been proposed for Murex eapuoinus. The taxon is Rhizophorimurex Oyama, 1950, with Murex eapuoinus Lamarck, 1822, as type by original designation. Oyama (1950) and Vokes (written comm. January 1989) place M. eapuoinus in Rhizophorimurex as a subgenus of Chieoreus Montfort, 1810. However, the radular characters (D'Attilio, 1988, fig. 5) leave its placement in Chieoreus not entirely resolved. A lectotype for M. eapuoinus was selected by Cernohorsky (1971, fig. 1) from the Lamarckian Collection in the Geneva Museum (lectotype 1099/23) and this lectotype was referred by him to Murex torrefaetus Sowerby, 1841. After further examination of a photograph of the 124.7 mm lectotype of M. capucinus taken by Mr. Cernohorsky (and sent to me by Dr. Vokes who received it from Mr. Richard Petit) I agree with Dr. Vokes (written comm.) that Mr. Cernohorsky was mistaken in his identification and the shell is M. eapuoinus of authors. Although Rhizophorimurex was cited in Radwin and D'Attilio (1975), it was inadvertently omitted in Radwin and D'Attilio (1976). Perhaps the publication of this generic taxon in a geological journal accounts for its lack of common usage. ACKNOWLEDGMENTS I wish to thank Emily Vokes for making the photograph of the lectotype of M. eapuoinus available to me for study and for her always stimulating discussions on taxonomic matters. My appreciation also to Mr. Cernohorsky whose slide of the lectotype made the examination possible. I am grateful to William K. Emerson who made the Oyama reference available to me.

HERTZ Associate, Department of Malacology, Los Angeles County Museum of Natural History, 900 Exposition Blvd . , Los Angeles, California 90007 In April of this year, a group from the San Diego Shell Club visited San Felipe, Baja California Norte, Mexico for the low tides. On the morning of April 6th at a -5.4 foot low tide, an abundance of TuvvtteZta anaotov Berry, 1957 (Figure 1) were seen on the mud flats north of town. Specimens were seen in the wet mud from the mid to low tide zones, and one specimen in the mid-tide area was observed laying eggs (Figure 2). Figure 1.

Mulliner San Felipe is the type locality of T. anaotov and the species is restricted to the northern Gulf of California (Hertz, 1979). Joyce Gemmell, who had lived and collected in San Felipe for eleven years, said that she had never observed egg laying in the species and I had never seen more than a few specimens intertidally Page 51 THE FESTIVUS Vol . XXI (6): 1989 during any one low tide. In previous collecting at San Felipe, the Turritella species found was usually T. anaotor. However, DuShane and Brennan (1969) note dredging juvenile specimens of T. nodulosa King and Broderip, 1832, off Consag Rock (east by north of San Felipe Bay, offshore approximately 20 miles) and Hertz (1980) lists Turritella leuoostoma Valenciennes, 1832, in San Felipe [one live subadult taken by David Mulliner in 1966 and dead specimens collected by Joyce Gemmell (Figure 3)]. In 1982, Martin Schuler, of San Diego, collected another live juvenile (42.3 mm L) and two dead specimens, and early this year Larry Buck, of the San Diego Shell Club, told me had had taken live T. leuoostoma in San Felipe. Then on the morning of April 7th at a -5.2 foot low tide on the large sand flat just south of the marina, live Turvitella leuoostoma were commonly seen and I observed one specimen with eggs. Unfortunately there was no camera to record this, but to my naked eye, the eggs appeared just like those of T. anaotor. I saw no T. anaotor at this beach. In questionong Joyce Gemmell about the T. leuoostoma , she mentioned that the shrimpers often dropped mollusks from other areas when they cleaned their nets. It is her view that this species, most likely deposited by shrimpers originally, has taken hold in San Felipe. ACKNOWLEDGMENTS My thanks to David K. Mulliner who tromped through the mud flats to take the photograph of the T. anaotor laying eggs. Figure 3.

XXI (6): 1989 THE FESTIVUS Page 52 CHICHIMECA, EARLY SHELL TRADERS AND ARTISANS HELEN DUSHANE 15012 El Soneto, Whittier, California 90605 Few know that an enterprising group of aborigines in the northern part of the state of Chihuahua, Mexico were very early shell collectors. In 1960, Dr. Charles DiPeso, archaeologist and Director of the Amerind Foundation in Arizona, with mostly native labor, unearthed a ruin in northern Mexico which previously had been visited by Lieut. Frederick Schwatka in the latter part of the nineteenth century. It is from Schwatka (1893) we learn "...the town of Casas Grandes ... takes its name, meaning 'big houses' from the ancient ruins situated in its suburbs, and comprising the largest found in this part of Mexico..." He further states of the natives, "They were a wonderful and interesting people, one that would repay careful study, even from the little evidence of their existence that is left." Casas Grandes was an urban center of an Indian civilization that flourished between 700 A.D. and 1040 A.D.; the city covered 260 acres. Only one eighth of it was excavated by Dr. DiPeso and his staff of workers and yet shells in the millions were recovered. This is not only the largest deposit of artifact mollusks ever recovered, but being the nucleus, it forms the distribution center of all similar artifacts found in other excavations in the southwest. Therefore, we can say that the early Casas Grandes inhabitants, through their enterprise, established the largest distribution center for shell artifacts that has ever been known. There was a vast frontier market which absorbed their products. They established and protected a trail and communications route running roughly E-W over the Sierra Madre for a distance of some 400 km to the Gulf of California. Two large integral warehouses in the west arm of the high-rise apartment complex offered further proof of the importance of shell trade in the life of the Chichimeca, a name used by DiPeso for these people. Apparently a system of forced labor was utilized in the working of shells assembled by them. Workers were housed in cell-like rooms with low ceilings, each cell harboring a specialty. In one room, a worker, or workers, fashioned the huge Strombus galeatus into trumpets. In another cell, workers fashioned Conus of several species into tinklers for the dancers to wear around waist or ankles. The very small shells of Nassarius iodes and Nassarius moestus were made into strands of beads. The most cunning workers fashioned the shells of Spondylus prinoeps , reminiscent in color of the precious coral (Isis) found only in the Mediterranean Sea, into small nodular beads. Dr. DiPeso labored for three years at Casas Grandes, through a grant from the Mexican government, with the provision that for a limited time he might bring back all the artifacts found to the Amerind Foundation at Dragoon, Arizona. One could only gasp at the multitude of shells assembled here. Fortunately, I had the opportunity to work with them for a week, making species identification of the entire collection. Of the 3,909,096 shells recovered, 3,821,051 were worked. There were 14 wooden apple boxes of tinklers {Conus) ; 14 similar boxes of Nassarius, 3,437,203 of them; 41 Strombus trumpets, some inlayed with turquoise and mother-of-pearl, others incised with patterns, usually of frogs. Most of the shells, almost 4 million of them came from the west coast of Mexico. Page 53 THE FESTIVUS Vol. XXI (6): 1989 Chichimeca was a term applied by DiPeso to the aborigines of the area. Gran Chichimeca territory extended from the Pacific Ocean on the west, from the Tropic of Cancer on the south at about 23°27'N and to the north to 38°N latitude. The province runs southward through southern Arizona, down into the states of Sonora and Chihuahua. Caravans traveled from Chichimeca to Mesoamerica trading diverse objects such as furs, bone, medicinal plants, colored paints, salt, coastal shells, minerals and brilliantly colored birds (macaws). Shell accounted for 98.4% of the raw material used to manufacture ornaments. Shells, principally from the Gulf of California, were trafficked some 400 km or 300 air miles over the Sierra from the Sonoran coast. Volumes of unstrung shell jewelry ornaments were found in the form of beads, bead pendants, strand dividers, tinklers, all intended to be parts of larger ornamental compositions such as necklaces, bracelets, earrings. The artisans utilized some 70 species of marine mollusks and one land snail. Of the 70 species involved, all were intertidal species from the Gulf of California except for four species dealt with separately in this paper. The material is listed in DiPeso (1974, vol. 6). The degree of expertise varied considerably, from the simple perforated whole shell to that of exquisite tiny red crosses fashioned from the hinge of the bivalve, Chcana eohinata. Sometimes whole shell ornaments were dyed a blue-green, or sometimes used as shell inlay on a larger ornament. In shape, shell pendants were square, triangular, ovoid and circular. The shell craftsmen often removed not only the spire but also the columella of gastropods like Oliva and Conus. This operation made the mollusks ring when they touched one another in rhythm with a dancer's body and were sometimes dyed blue. They were attached in bunches to dance wands, as rows of fringe on dance skirts, or as noisemaking girdles, or as anklets. About 500 artifacts of shell were designed as arm bangles, wrist bracelets, and finger rings. The arm forms were modified by cutting away the center of a large bivalve, leaving an outer margin ring. Sometimes they incised the umbos in the likeness of animal faces or painted them blue or red, rarely they covered the entire outer surface with layers of a cloisonne-like design. Women sometimes wore as many as 26 arm bracelets on one arm. Surprisingly, among the many Panamic mollusks a piece of worked Haliotis fulgens (green abalone) , about 4 inches long and 1^ inches wide (use unknown) and a drilled pendant of Haliotis cvacherodii (black abalone), one inch long by l/16th of an inch wide, indicate there must have been some barter between the coastal Indians of the Calif ornias and those of Casas Grandes. This was indeed a surprise as abalone does not inhabit the Gulf of California, but it strengthened the growing feeling that these people were masters at trading mollusks. Proof is indicated here that trade went on between people of the mainland of Mexico and the outer coast of Baja California; proof that the aborigines of Baja California collected mollusks, not only for food, but for barter. Haliotis fulgens does not occur today in the waters of the Gulf of California. Nor does it occur as a fossil in the early kitchen middens of the Indians or in fossil deposits bordering the Gulf of California. Its range is in the Pacific coastal waters of central Oregon south to the central portion of Baja California. According to Ronald Ives (1961), "Paleontological studies show that the range of the abalone has been quite stable in pleistocene and recent times, despite known changes in sea levels, ocean currents, and ocean temperatures, particularly during the Ice Ages. The first Californians of whom we have records found the abalone in about the same places where we find them today. This is known to be true, for abalone shells and shell fragments are found in the oldest middens of the California coasts." About 300 years ago (circa 1687) Father Francisco Eusebio Kino, at the request of Philip IV, King of Spain, explored the land and established a chain of missions, which, like beads on a string, reached as far north as Tucson, Arizona. He brought religion, agriculture and domestic meat production to the land, but more importantly, he proved that Baja California is not an island. Known as "The Apostle to the Pimas," Vol. XXI (6) : 1989 THE FESTIVUS Page 54 Kino, early in his work, noted there was extensive trade of the green abalone shell {HaZiotis fuZgens) among the Indians. He saw that the aborigines used them as drinking cups and as other useful objects. In December 1684, while on the west coast of Baja California (west of the Mission of San Jose de Comondu at approximately 26°03'N; 112°17,W) as a cosmographer for the Antondo Expedition, he observed the Indians utilizing a certain shell of brilliant iridescent shades of blue-green. It was the abalone, HaZiotis fuZgens . When he questioned the Indians regarding their origin they gestured and drew maps in the sand indicating they had procured the shells in trade with other Indians a long walk to the north, then west over high mountains, a journey of 10 to 12 days on foot. Bit by bit for almost 15 years Father Kino gathered information until he thought he had enough evidence to confirm his conclusion that Alta and Baja California were a continuous land mass, with no water course separating them, and he so reported to Charles II, then King of Spain. Bolton (1948) reports, "This information was received dubiously by the throne." Actually it was many years before maps were changed to agree with Father Kino's conclusions. Today, our maps of the area differ little from the beautiful and precise map Father Kino drew and dated 1701, "Passo por Tierra a la California." Although Kino's interest in shells cannot be considered a hobby, or a profession, he collected as assiduously as any present-day conchologist . His work reflects the earliest historical record of shell collecting on the west coast. Yet it is a curious fact that only two shells have been named for him, one a land snail, HoZospZra kinonis 3 Baily and Baily, 1940 and the other the marine species Cevithiopsis kinoi Baker, Hanna and Strong, 1938. Historically, extraneous material is gathered that indicates the aborigines collected shells for food and personal adornment long before the European Caucasians arrived. The beaches of Baja California offered a rich and varied fauna for their use. We know Indians traveled surprisingly long distances to enable them to have a change of diet from forest and desert plants and animals, to shellfish and crustaceans A personal interview with Delfina Cuero, a Diegueno Indian (September 5, 1968) revealed that as a young girl she accompanied her family on foot, as her ancestors before her had done, on more or less regular summer trips from the vicinity of Tecate, Baja California Norte, to San Felipe Bay on the shores of the Gulf of California in order to obtain fish and clams to eat. She reported that two edible clams were common on the sand flats of San Felipe Bay and with an educated guess one can surmise from her description that they were Dosinia ponderosa and Chi-one oortezi . When more shellfish was taken than they could reasonably eat at the time, the Indians would clean, wash and cut the rest and spread them on the rocks to dry. A story told by this same Indian woman [from Shipek, 1968] is worth repeating here. "There was a story about the OZiveZZa shells; they were babies that fell from the stars. They used to say; 'When the dipper in the sky (the Big Dipper) gets too full, it is dumped out. Then these small shells fall all around near the ocean'." While it is thought that the majority of the shell artifacts came from the Guaymas, Sonora, Mexico area, two species obviously were collected much further south, in the vicinity of Nayarit, Mexico. Chama echinata Broderip, 1835, is a common bivalve on the beach rocks off the state of Nayarit. It can be taken much less commonly as far north as Mazatlan. Archaeological specimens of PersiauZa bandeva Coan and Roth, 1965 (a pint of them) were sent to Dr. A. Myra Keen for identification. The type locality for these is Banderas Bay, Nayarit and was the only locality where they had been taken alive. Through a strange coincidence. Dr. Keen was on a col- lecting ship anchored in Banderas Bay. One of the young, Mexican crewmen begged to be allowed to try SCUBA. With a small amount of air he descended to approximately 15 feet. From the substrate he snatched two handsful of the muddy substrate. Returning to the surface, he deposited the mud on the sorting table. From it Dr. Keen extracted small PevsiouZa she had never seen before and she took them back to Stanford. These proved to be the same species, undescribed, that had been sent her Page 55 THE FESTIVUS Vol. XXI (6) : 1989 from Casas Grandes. Subsequently, Coan and Roth described the species as Pevsicula bandera for the bay in which they had been found. The specific name "bandera" comes from the Spanish word meaning flag. The bay was so named by the Spaniards when they were welcomed by the Indians waving flags and greeting them at the shoreline of the bay. When excavations of one-eighth of the extensive city of Casas Grandes had been completed by DiPeso and his staff, the ceramics, bone, stone and shell material was brought to the Amerind Foundation located outside Dragoon, Arizona for further study and analysis. After the artifacts had been examined, measured, identified and tagged they were returned to Mexico and may be seen today in the National Museum in Mexico City. LITERATURE CITED BAILY, JOSHUA L.

CLUB NEWS THE SAN DIEGO SHELL CLUB MEETING — MAY 18, 1989 The May meeting was called to order by Jules Hertz, substituting for the vacationing President Larry Buck and Vice President Bob Yin. Guests and new members Stan and Mary Regula were presented. Jules then introduced Don Shasky, the evening's speaker whose presentation was "My Last Seven Years — at Cocos Island." Don's talk traced his seven trips to Cocos Island, Costa Rica with beautiful slides of the area and of many of the shells — endemic, Indo-Pacific and as yet undescribed — that he and his fellow collectors found there. The talk was informative, fun and greatly enjoyed by the overflow audience that came to hear him. Don also brought in a beautiful display of some of the Cocos Island shells he'd found. [An adaptation of Don's talk will appear in the August issue of The Festivus.] Carole Hertz brought in a birthday cake for Don when she learned that he was spending his birthday giving his talk to the Club. Both talk and cake were enjoyed by all. Following the refreshment break, with additional sweets provided by Rick Negus and Paula Barton, there was a short business meeting. Don Pisor discussed the arrangements for the COA meeting from June 19-24 and urged Club members to help and attend. Carole Hertz told of the plans for the Club's welcome party for COA on Monday evening June 19th and suggested Club members attend the function. (For details see page 57 .) The door prize was won by Stan Regula.

Dr. Chris Barnhart, whose program, "Desert Snails, Lunar Moths and Other Bits of Natural History" gave us a fascinating look into the world of terrestrial mollusks with their adaptations to the rigors of an arid environment. Chris' outstanding slide presentation and absorbing lecture gave Club members a clearer understanding of the complex evolutionary patterns of mollusks. Chris also discussed the filter feeders such as barnacles and special attention was given to the breathing of snails in their dormant states. After the coffee break, with refreshments provided by Margaret Mulliner and Wayne Reed, it was announced that the Club has membership forms thanks to the efforts of Kim Hutsell. Club T-shirts were sold during the break and will be available again at the July meeting. Sweatshirts with the Club logo will also be on sale. Larry Buck announced that Mike Johnson has been trying to get dive trips organized. A trip to San Miguel Island is on the horizon and other trips may include one to Puertecitos. The door prize was won by guest Janice DeMarco of Phoenix, Arizona.

Vol. XXI (7) : 1989 THE FESTIVUS Page 60 THE RANGE FOR MACRON AETHIOPS (REEVE, 1847) HELEN DUSHANE Research Associate, Los Angeles County Museum of Natural History, 900 Exposition Blvd. , Los Angeles, California 90007 Macron aethiops .(Reeve, 1847) has long been accepted as an endemic species within a small area of the outer coast of Baja California Sur, from Laguna San Jose (Guerrero Negro) south to approximately Bahia Magdalena (Figure 1). Below are collecting records of this species which show it to have a much longer range than previously thought. Playa San Ramon is a shallow embayment on the Pacific side of Baja California Norte, Mexico (30°45'N; 115°50,W). It is 105 miles south of Ensenada and reached by a short (2.8 miles) stretch of road off paved Mexico Highway #1. We stumbled on to it trying to locate fresh tomatoes grown in the rich, silty soil of the Santo Domingo River channel. Industrious Bajaneros have grown tomatoes there for a number of years. We asked if the road continued to the beach and the reply was, "Si, si muy buena playa, muy limpia." Planning originally to stay only long enough to purchase vegetables, we stayed three days during a period of low tides. The beach was smooth and wide with outcroppings of rocks here and there, and offshore a rocky sheet reef showed at extreme low tide. Our collecting during that time taught us that the San Ramo'n beach warranted several additional trips which we made throughout the years. Wading out to the sheet reef we found small, dwarf specimens of Macron aethiops (Figure 2) It is considered to be an endemic species of the Surian Province, a name proposed by Valentine (1966:203), and encompassing, according to him, an area of the southern shelf segment between about Punta Eugenia and Cabo San Lucas which is coincident with the west coast of Baja California Sur. This is a range extension of this species approximately 350 miles north of its northern boundary. Two of the nine specimens collected are at the Los Angeles County Museum of Natural History (LACM M-563) and seven specimens are at the American Museum of Natural History (AMNH 232094). Sizes of the seven specimens vary from a length of 34.2 mm, width 20.1 mm to a length of 13.5 mm and width of 8 mm. All specimens collected August 18, 1963 were dead taken and somewhat damaged. Since that long-ago trip we have returned many times to augment our shell collection with numerous fine specimens of other species. We have checked sources in two major institutions to find that this species is not endemic to the Surian Province. Within the Surian Province the following stations have been reported: Figure 1.

As Recent specimens, the Playa San Ramon collecting site is the farthest north along the Baja California coast that this species has been collected. As Pleistocene fossils. Grant and Gale (1931:649, pi. 28, fig. 8) reported this species California. One Pleistocene specimen (smooth form) from the San Pedro Sand, Gibson Road, San Pedro, California (length 49 mm, width 23 mm) was collected by Yvonne Albi in 1983. It is in the Albi collection. Thus, we see that the range for this species is far greater than has previously been reported. LITERATURE CITED GRANT, U.S., IV and HOYT RODNEY GALE 1931.

HERTZ Associate, Department of Malacology, Los Angeles County Museum of Natural History, 900 Exposition Blvd., Los Angeles, California 90007 In February 1988, Richard Cerutti of the Paleontology Department, San Diego Natural History Museum, brought me seven specimens of a terrestrial snail which neither of us had seen before (Figure 1). The specimens from 6.1 to 12.6 mm maximum diameter, were collected by him in Balboa Park, San Diego, California across from the west entrance of the San Diego Natural History Museum (near the snack bar). They were at the base of a paper plant ( Fatsia japonioa) . The specimens are now in the collection of the Marine Invertebrate Department of the San Diego Natural History Museum (SDNHM 93371). The specimens were sent to Dr. Barry Roth who kindly identified them as Oxychilus draparnaldi (Beck, 1837). The species, native to western Europe, was introduced in North America about 1850 or earlier (Bequaert and Miller, 1973) and is found in many parts of the United States. Pilsbry (1946) listed it from such diverse locations as: Boston, Mass.; Washington, D.C.; Charleston, S.C.; Chicago, 111.; Portland, Ore.; Seattle, Wash.; and San Francisco, Oakland and Balboa Park, San Diego, Calif. — this last collected by the late Dr. Joshua L. Baily. Pilsbry (1946) stated that the species "is said to be carnivorous by preference." That would be good news for the gardeners. Figure 1. Oxychilus drapamaldi (Beck, 1837).

CONVENTION - SAN DIEGO KIM HUTSELL 1154 12th Avenue, San Diego, California 92101 The 17th Annual Convention of the Conchologists of America has come and gone. Hosted by the San Diego Shell Club (and a first for San Diego) the week long convention was hailed as a resounding success by nearly all of the 197 registrants. So pleased were the COA board members with this year's convention that, even before it was over, there was talk of the COA returning to San Diego in the near future! During the convention, shell enthusiasts from all over the world not only got a chance to attend some outstanding programs on seashells and related subjects, but had ample opportunity to meet and talk with the speakers as well. Speakers included R. Tucker Abbott, Ruth Abramson, Eliezer Rios, Donald Shasky, Anthony D'Attilio, Richard Goldberg, Hugh Bradner , Olive Schoenberg, Don Pisor, Ron McPeak, Bob Schoening, Dave Leighton, Gary Rosenberg, David Mulliner, John Baker, and Barry Wilson, who came all the way from Australia and was our outstanding banquet speaker. Along with the annual COA Auction and the Dealers' Bourse, convention goers were treated to a Silent Auction and a Dollar Table where many bargains on specimen shells could be found. (Reportedly, this year's auction, to raise operating funds for COA, was one of the most successful ever). Participants also got a behind-the- scenes-look at Sea World and Scripps Aquarium, a San Diego Harbor Dinner Cruise, and the chance to do some shell collecting in Mexico. From the displays of local and worldwide shells to the underwater photos, from the club pin trading sessions to the press coverage by PM Magazine, there was always something going on, always something interesting to look at, and always someone interesting to talk with. Some people renewed old friendships and almost everyone made new ones. Much to the relief of the organizing committee, most of the planned activities came off without any major problems and only a few minor ones. Although the committee worked long and hard to assure the smooth operation of the convention, a word of thanks must go out to all those who volunteered to help with registration, club tables, making announcements, running errands, and just plain asking if there was anything they coud do. To try to summarize the week's events in one or two pages is nearly impossible. All that can really be said is that anyone who missed the 17th annual convention of the Conchologists of America missed the biggest, most important event to shell collectors that San Diego has ever seen! Page 64 THE FESTIVUS Vol. XXI (7 ) : 1989 A REPORT ON THE COMBINED ANNUAL MEETING OF THE AMERICAN MALACOLOGICAL UNION AND WESTERN SOCIETY OF MALACOLOGISTS JULES HERTZ 3883 Mt. Blackburn Avenue, San Diego, California 92111 The combined annual meeting of the American Malacological Union (AMU) and the Western Society of Malacologists (WSM) was held at the Davidson Conference Center, University of Southern California, Los Angeles, California from 25 to 30 June 1989 with some additional slide presentations at the Los Angeles County Museum of Natural History and some business sessions at the University Hilton, Los Angeles. In addition to four days of papers, there were many planned social events such as the Presidents’ Reception, a barbecue, auction and the traditional banquet. Three years of planning by AMU President, James H. McLean and WSM President, Hans Bertsch resulted in a truly outstanding joint meeting. The Presidents’ Reception in the main Foyer of the Natural History Museum on Sunday evening was an opportunity to renew old acquaintances and make new ones in a very beautiful setting. Drinks and desserts were provided. This and the specially designed logo by Sue Stephens, prominently displayed on the cover of the program and also on shirts for sale, set the tone for a very friendly and cooperative joint meeting. The first day featured a symposium. Biology of Pelagic Gastropods, as well as a concurrent afternoon session of contributed papers on Non-marine Mollusks. There were 13 papers presented in the symposium with most of the world’s workers on pelagic gastropods present. Authors were from the Federal Republic of Germany, Australia, France, Argentina, Canada, and the U.S. Support for this symposium came from the USC - Sea Grant Program and from the AMU Symposium Endowment Fund. The photography of these minute animals was superb and even seasoned biologists were appreciative. The second day's program included a symposium, Biology of Scaphopods, as well as contributed paper sessions on Fossil Mollusks and Opisthobranch Gastropods. Rarely does one get to hear a paper on scaphopods, and to have a symposium devoted to them is unusual. I particularly enjoyed the paper presented by Ronald L. Shimek on Resource Utilization in a Multi-Species Scaphopod Assemblage. On the third day there were two sessions of a symposium devoted to land mollusks in honor of Walter B. Miller. Here too, there were papers presented by an array of international workers. In the afternoon, there was a concurrent session featuring contributed papers on marine gastropods. The final day of presentations featured a concluding session on land mollusks and morning and afternoon sessions on marine bivalves, cephalopods and gastropods. In general, there were papers covering most of the molluscan phyla presented by workers from many countries. The papers I personally found most interesting were Gary Rosenberg's "Independent Evolution of Terrestriality in Truncatellid Gastropods in Caribbean Islands," Rudiger Bieler's "Sessile Slit-Shells — A first Look at Sitiquarta Anatomy and Biology (Cerithiodea:Siliquariidae)" and Richard S. Houbrick's "Anatomy, Reproductive Biology and Systematic Position of Fossavus ambiguus (Linne) (Fossaridae: Prosobranchia) . " On Thursday evening, June 29th, the traditional banquet was held at the Town and Gown Banquet Hall on the USC campus. After a fine meal we were treated to a presentation by Robert R. Hessler of Scripps Institution of Oceanography. He spoke on the most recent developments in the global exploration of deep-sea hydrothermal vents and showed slides of the hydrothermal vents of the Mariana Back Arc Basin visited in 1987 and compared this area to earlier trips to hydrothermal vents along Page 65 THE FESTIVUS Vol . XXI(7): 1989 the continental rift. This latest visit to a supposedly isolated thermal vent site found some of the same animals as previously seen in other sites, but it also pro- duced animals not previously found. The manner in which these new sites are populated still remains a mystery. There were many other social events during the week. But by far the highlight of the meeting was the auction. This was the most successful WSM auction ever, featuring the non-stop, humorous dialogue of auctioneer Hank Chaney and excellent donated material of shells, books, and art work. The proceeds were earmarked for student grants and all the attendees felt good about participating, having a good time — and sometimes overbidding. There were slide presentations of general interest on two of the evenings with refreshments provided by the Conchological Club of Southern California. A dealers’ bourse was held on the third and fourth days, providing opportunities to view and purchase shells, books, art work, and shell motif objects. The last day of the meeting was devoted to field trips, and one could choose to go dredging, diving, visit fossil sites or visit the Malacology and Invertebrate Sections of the Natural History Museum. Carole and I opted for the dredge trip and it was a very well run and successful trip. We joined approximately 25 others on the R/V Vantuna on a beautiful, rather calm day for about three hours of dredging and trawling. Two dredge hauls were taken in a rocky area at 14 fathoms and two otter trawls were taken in muddy areas, one at 50-60 fathoms and the other at 100 fathoms. Each haul was dumped in a large sorting box which was immediately surrounded by many of the participants on their hands and knees trying to separate the mollusks from the fishes, crabs, shrimp, etc. The mollusks were gathered and so was the sifted grunge and put into packets which were later distributed by a draw of numbers. Several excellent specimens were found including a large, live collected Megasurcula aarpenteriana (Gabb, 1865), a live Cancellavia erawfordiana (Dali, 1891), a dead Solemya panamensds Dali, 1908, and several Pecten ddegensds Dali, 1898. Next year, the AMU will be meeting at Wood’s Hole, Massachusetts and the WSM will be meeting at the University of Washington in Seattle. In 1991 there will again be a combined AMU/WSM meeting to be held at the University of California at Berkeley.

Although the photographs are approximately 3X3 inches, they are clear, sharp and the color is excellent. Most of the living specimens are pictured in their marine habitat. Reportedly thousands of species of invertebrates inhabit the Gulf. A. Myra Keen in her 1971 book "Tropical Seashells of Tropical West America" lists over 3,000 species of mollusks alone. The selection of the 283 species in this book covers nine phyla and effectively shows the diversity of invertebrate forms in the Sea of Cortez, one of the richest areas in the world for marine life. Alex Kerstitch is a Research Associate in Marine Science at the University of Arizona and coauthor of "Reef Fishes of the Sea of Cortez" as well as an award- winning photographer. Three major contributors authored sections of the book. Hans Bertsch, whose publications include "Hawaiian Nudibranchs , " Ronald H. McPeak, co- author of "The Amber Forest" and L. Yvonne Maluf whose many papers on echinoderms include a report on the classification of eastern Pacific echinoderms. The Forward for the book was written by Richard C. Brusca, Curator of the Department of Marine Invertebrates, San Diego Natural History Museum, whose own book on this area written in 1980, "Common Intertidal Invertebrates of the Gulf of California," is widely used by those interested in the fauna of the Gulf and was the result of intensive study for many years. Dr. Brusca focuses attention on ecology, conservation and the future of this important resource. A short introduction is followed by an explanation for using the book, mention of each phylum and a short glossary of technical terms. The references include only well-known books and papers. The text for each species is placed conveniently adjacent to the photograph and the binomial Latin name is given. It is customary to include the name of the author of each species in a scientific work but this is omitted here. The author plus the date the name was first published is a common practice by malacologists . The date is omitted also. The common English name is included and if none was known, a name was created. Not too creative, however, since Lepas ansi f era was simply called Goose barnacle and Chthalmalus anisopoma is distinguished only as Acorn barnacle. Murex tricoronis is called Longspine murex. In the genus Murex most of the more than 30 species have long spines. Often in the case of a species bearing the name of a person such as Epitoniim billeeanum _, named for Billee Brown, the person's name was disregarded and, thus, instead of Billee 's wentletrap this species was called Coral wentletrap. Another example is Bajaeolis bertschi named for Hans Bertsch; the common name given is Rainbow sea slug. Further, the author is bound to cause confusion with the use of the common name, Diomedes' triton, for Tritonia diomedea , a nudibranch. The English term triton has been a common name for more than 100 years and refers to the family Ranellidae (Cymatiidae) in the Mesogastropoda. The text contains a brief description and includes size, distribution, habitat and remarks. The latter two categories contain life history information gleaned from many sources as well as from the author's own experience and is a real contribution to our knowledge of this fauna. Although, for the most part, the book follows phylogenetic sequence, in the molluscan section, Strorribina maculosa , which is a columbellid was placed before the Naticidae which would make it a mesogastropod instead of following the Muricidae in the Order Neogastropoda. Harpa crenata and Fusinus dupetitthouajcsi should exchange Page 67 THE FESTIVUS Vol . XXI (7) : 1989 places for classification purposes. On page 63, number 143 is listed "Trapania n. sp. Yellowtip trapania." The use of "n. sp." is ill-advised since that designation is reserved for a description of a new species.. I thought the cover photograph of Jenneria pustulata was outstanding and equally impressive were Baseodiseus mexicanus 3 Muvex trioovonis 3 Chromodoris annulata 3 Cymothoa exigua3 GnathophyZZum panamense and ~Petvolisth.es mavginatus. Only MeZibe Zeonina and Thov aZgicoZa were too dark and Ptevopuvpura aentrifuga positioned in such a way as to be unidentifiable. This book is a valuable contribution to our knowledge of the marine invertebrates of the Gulf of California and I recommend it to all who dive or snorkel in the Sea of Cortez and those interested in the fauna of these waters. Barbara W. Myers NOTICES OF NEW PUBLICATIONS PELAGIC SNAILS The Biology of Holoplanktonic Gastropod Mollusks This new book by Carole M. Lalli and Ronald W.

NEW MEMBER Yvonne Albi, 7001 Vista Del Mar Lane, Playa Del Rey, CA 90293 Vol. XXI (8): 1989 THE FESTIVUS Page 70 PSEUDOMELATOMA GRIPPI (DALL, 1919) AT THE CORONADO ISLANDS KIM HUTSELL 1154 12th Avenue, San Diego, California 92101 After diving off the Coronado Islands for the last eight years, there are few shells from that area which I don't recognize immediately. However, this past January (1989) I happened across a shell I'd never seen before. Since it was only about a centimeter long, my first thought was that it was a juvenile form of some- thing else. . .Mi tra idaes perhaps, or Crassispira semiinflata. But it was in the wrong place. Those species like a silty, almost mucky substrate and this specimen was in a hole, under a rock, on a rocky bottom at about forty feet. It was frustrating. I didn't have a name... I didn't even have a genus for this animal. To make things worse, it was my last dive of the day and there wasn't enough air left in my tank to look for more. Back on board the boat, I turned the shell over and over. The animal was a grayish-brown, not white like Mitra idae and the sculpture was completely different from either Mitra idae or Crassispira It wasn't until Dave Mulliner gave a workshop on shell photography that I saw that this little shell was something different indeed. Dave set up the shell under his camera lens as part of his demonstration and I got my first really good look. Now I was sure... I had absolutely no idea what it was ! Carole and Jules Hertz seemed confident that it was a species of turrid but couldn't find a matching description and illustration in the literature they had. They brought photographs of the specimen to the recent AMU/WSM meeting in Los Angeles and James H. McLean, of the Los Angeles County Museum of Natural History (LACM) tentatively identified it as P sue dome latoma grippi (Dali, 1919) (Figures 1 and 2). Carole and Jules checked it with specimens in the LACM malacology collection and confirmed Dr. McLean's identification. The 16.7 mm long specimen 1. varies from that of the original description in that the "pale peripheral band" noted by Dali (1919) appears on the nodes only, becoming paler on the body whorl behind the aperture. Figures 1 and 2. Pseudomelatoma grippi (Dali, 1919). Length: 16.7 mm, Leg. K. Hutsell, January 1989. Collected diving off the Coronado Islands in about 40 ft. on rocky bottom. Photo: David K. Mulliner Page 71 THE FESTIVUS Vol . XXI (8): 1989 The specimen has a complete protoconch of -lh whorls (Figure 3) which is smooth, glassy and amber-colored. Dali described the species from San Diego and McLean (1978) published the range as San Pedro, California, to San Martin Island, Baja California Norte, Mexico. ACKNOWLEDGMENT I would like to thank Dave Mulliner for photographing the shell. LITERATURE CITED DALL, WILLIAM H. 1919.

XXI (8): 1989 THE FESTIVUS Page 72 m LAST SEVEN YEARS — AT COCOS ISLAND DONALD R. SHASKY 834 W. Highland Avenue, Redlands, California 92373 Cocos Island, Costa Rica is a tiny, remote spot on this planet that I never expected to visit. One might ask why anyone would want to go to such a place. First, because it is there. Few people had been there; and no scuba diving shell collectors, as far as I knew, had blown a tank of air in its waters. To set the scene: Cocos Island is 278 miles from any land; it is uninhabited except for three marine guards; it is only ten square miles and is of volcanic origin; its rainfall is 22 feet per year; there are 200 waterfalls; there is an abundance of game fish, including a very large shark population, especially crenulated hammerheads; and the water is beautiful and clear. It was not promising malacologically , judging from the number of species that had been reported from Cocos Island prior to my first visit there in 1983. Previous faunal lists included only 118 species, which included the cephalopods. Before I left my hope was to find three aces: Cypraea rashlezghana Melville, 1888; Morum veleroae Emerson, 1968; and Haliotis roberti McLean, 1970. C. rashle-ighana had been reported based on one beach specimen taken sometime during 1905-06. Cocos Island is the type locality of the other aces. During the late fall of 1982, the 84-foot motor schooner Victoria af Carlstad, which was built by the crew in their hometown of Carlstad, Sweden, began regular diving trips from its base in Puntarenas, Costa Rica to Cocos Island. It is a trip of from 40 to 50 hours, depending on wind and currents. Victoria is fully equipped for diving with a great crew captained by Leif Falgren. The dive master, Kevin Burke, was the only non-Swede. He is a wiry Irishman born in England whose home is now in Bermuda. The divers divide up, when our shelling group is there, into the shellers and the sharkers. The sharkers waste their time photographing sharks; while we, the treasure hunters, overturn everything turnable during the day, prowl the sand bottoms at night, set the tangle nets in the afternoon, and pull them in in the morning. If there is time, we dredge. To and from the island, we troll for game fish from before sunup to sundown. Thirty to fifty pound dorado are not uncommon. We occasionally hang a marlin or a sailfish, and as we get closer to Cocos, there can be huge schools of yellow-fin tuna and small schools of wahoo. Once at the island, there is an early morning (before breakfast) deep dive, an early afternoon dive, and an after dinner night dive. The tangle nets are dropped in 300 feet of water, usually off Chatham Bay. These are hauled in after one or two nights on the bottom. There are numerous islets and seamounts around the island, which provide various habitats in which to collect. Some of these dive sites can be very hazardous, especially the one we call Baja Alcycone named for Captain Cousteau's boat, whose crew found it about two and one-half years ago. It is 90 feet down to the top of this mount, with most of the shelling done from 100 to 125 feet. Currents can come up quickly. The skiffs anchor there, so we try not to lose sight of the anchor line. Lest I forget the shellers. Let me list the principals, all members of the San Diego Shell Club. Gene Everson 1 trip Kirstie Kaiser 5 trips Doug von Kriegelstein 4 trips Michel Montoya 7 trips Don Shasky 9 trips Page 73 THE FESTIVUS Vol . XXI (8) : 1989 Kevin, the dive master, holds the record for most dives at Cocos with about 1,700. I am number two with from 325 to 350. Kevin is also a sometime sheller. Because of all the sharks, he refused to dive at night until last year when he saw the good shells we were finding. Through the years, there have been many exciting finds. During my 1983 trip I found my first ace, Cypraea rashlieghana : or was it? When I returned home, I sent the shell, a beautiful, live-taken one from 60 feet, to Dr. Pat Burgess in Honolulu. He wrote that what I had was a new species that would be described in the Venus . It is C. alisonae Burgess, 1983 (Figure 1). All of us have found several of these, and we are sure that the 1905-06 beach specimen is not C. rashleighana but C. alisonae. In 1984, Gene Everson brought a tangle net. When stretched out, these nets are 6 feet wide and 100 feet long. At that time, we baited the net with chicken bones (a very messy job), weighted it heavily, and dropped it down to 300 feet. It was left overnight. The next morning when we pulled it up, it was mostly empty except for a beautiful, large, undescribed Murex. Gene and I each found a hermit crab specimen while diving. In 1986, I found another live one in my net. In 1987, Kirstie and Doug also had nets, and we found several more. All of the specimens collected through 1987 became part of the type lot for what is now known as Phyllonotus eversoni D'Attilio, Myers, and Shasky, 1987. In the nets and also in the dredge, there have been numerous specimens of a new Strombus (Lentigo) . This is in manuscript. In the last few years, we have stopped baiting the nets, with just as good results. Without the bait, there are lots fewer crabs to remove. From diving, dredging, and tangle-netting, we have about 40 undescribed species. Several of these have Indo-Pacific affinities. The list of Indo-Pacific faunal species that we have found at Cocos Island is long. A partial list includes: Figure 1. Cypraea alisonae Burgess, 1983.

Once I had unpacked at home, gone through the grunge, and talked with Kirstie, Doug, and Michel, it wasn't long before the next year's trip was on our calendars . This year we were still collecting Cypraea alisonae3 but the two other aces were somewhere buried in the deck, and I had resigned myself to failure. On the first haul of our tangle nets this year, an absolutely marvelous specimen of Morion veleroae (Figure 2) was waiting to be untangled. Now the problem was that I wasn't satisfied with a pair of aces. I still wanted "three of a kind." On the last haul, just before we started back to Puntarenas, my net came up with a tremendous snarl loaded with small pieces of a beautiful red-colored coral. I knew it would take hours to unsnarl the mess and to get the net clean. What seemed like a hopeless task, soon became a tedious joy when I found the first, which happened to be the largest of six, Haliotis roberti (Figure 3). Mission accomplished!!! Figure 2. Monon veleroae Emerson, 1968, Figure 3. Haliotis roberti McLean, 1970 - Page 75 THE FESTIVUS Vol . XXI (8): 1989 I must add that a few days earlier in a similar snarl, I had found a specimen of a species that had never been on my want list. It was attached to the same kind of coral as the HaZiotis robert'i. It was a 50 mm specimen of the curious chiton PZaciphoveZZa bZai-nv'ZZZi'i (Broderip, 1832). On Doug's last pull of his net was a single specimen of an undescribed species of TrZtonoharpa . Our accomplishments have been rewarding. We have increased the number of known species of mollusks from Cocos Island from 118 to about 500. Michel, Kirstie and I are in a continuing process of updating our species list. We hope to publish it soon. ACKNOWLEDGMENT I thank Dave Mulliner for making black and white prints from my color slides. Figure 4.

XXI (9) : 1989 CLUB NEWS FROM THE MINUTES - SAN DIEGO SHELL CLUB MEETING - AUGUST 17, 1989 President Larry Buck welcomed all members and guests to the August 17th meeting and invited new faces to make themselves known. Our speaker of the evening, Richard Herrmann, Club member, underwater photographer and marine biology diver took us on an incredible underwater marine biology photo excursion from the depths off the Channel Islands to undersea scapes off Santa Rosa and San Miguel Islands. Richard's superb presentation blended his talent as a narrator with his creative ability to document unique marine fauna on film. His camera captured everything from bright orange colonizing anemones off the Coronados to colorful hydrocorals seen during night dives. Of special interest were his photographs of local living shell species and a new unidentified jellyfish. Richard's presentation was a thrilling encounter with living mollusks and other marine life. Margaret Mulliner announced the sale of back issues of shell publications, magazines etc. to be held during the break and an announcement was made that San Diego Shell Club t-shirts will not be available again until at least April after the present stock is exhausted. Larry Buck told of a proposal by a private group to cultivate abalone off the Point Loma kelp beds. Members may wish to study the proposal to see how it may affect our marine environment and the collecting of abalone. The proposal is available to members and those concerned should send their comments to the Department of Fish and Game. The tasty cookies at the break were provided by Marge and Ken Lindall and the shell drawing was won by Wayne Reed.

Highland Avenue, Phoenix, Arizona 85018 The nomenclature for Panamic province chiton taxa has undergone many changes since Thorpe’s synopsis in SEA SHELLS OF TROPICAL WEST AMERICA (Keen, 1971). This paper consolidates information published since 1971 so that the references can be easily found and brings the list of species present in the province up to date. Systematic arrangement follows that of Van Belle (1983) as modified slightly by later authors. Species are listed alphabetically within a genus. All species in Keen (1971) are listed and shown with the "Keen number" in brackets after the name. Taxa which differ from those given in Keen (1971) are in bold type. Since the purpose of this paper is to report changes in the literature without being judgmental, synonyms are listed as published by each author, with the exception that those shown in Keen (1971) are not repeated. Where authors disagree, both versions are shown in date order. The Panamic province, as used by Keen (1971), lies between Magdalena Bay, Baja California Sur, Mexico (about 25°N) and Punta Aguja, Peru (6°S). Seventy-seven species and two subspecies of chitons are currently recognized as occurring in the province. Of the 56 chiton species names originally shown in Keen, only 34 retain species level. Nineteen of the twenty-two new species described since 1971 are considered valid. The remaining species are new to the Panamic province or earlier names not included by Keen. I would like to thank the many people who have contributed to this paper. Robert Koch of Phoenix, Arizona, and Col. George Hanselman of San Diego, California, read and corrected early drafts. Dr. Douglas J. Eernisse, Museum of Zoology and Department of Biology, University of Michigan, critically read the manuscript and offered many valuable suggestions. A very special thanks is due him. Dr. William G. Lyons of the Florida Department of Natural Resources, Bureau of Marine Research offered clarifications on some taxa. Carole and Jules Hertz of San Diego, California, encouraged the project and edited the final draft. Without them it would not have been completed.

Club members weren't about to miss this big event of the year. Earl Flores brought the charm of Mexico and the warmth of the Old West with his talented voice and guitar. Members enjoyed his live music as they dined on authentic Mexican dishes; everything from enchiladas to zesty South-of-the-Border style salads. We thank Toni and Larry for again hosting the September party and for the warm welcome into their home. Wayne Reed SAN DIEGO SHELL CLUB PINS For the first time the San Diego Shell Olub has a Club pin. The handsome pin has the Club's name and logo, the Festive Murex shell, Pteropurpura festiva.

HERTZ Associate, Department of Malacology, Los Angeles County Museum of Natural History, 900 Exposition Blvd. , Los Angeles, California 90007 Two more San Diego County land snails have been collected by Richard Cerutti of the Paleontology Department of the San Diego Natural History Museum. Plesarionta stearnsiana (Gabb, 1867) (Figure 1) was found living: on the ground beside Telegraph Canyon Road in Chula Vista, California, in January of last year. Richard Cerutti said they are "real common on the coastal mesas in Chula Vista." Figure 1. Plesarionta steavnsiana (Gabb, 1867). (SDNHM 93400 ). 19.3 mm max. diam. Leg. R. Cerutti, January 21, 1988. Location: Telegraph Canyon Road, Chula Vista, CA Photos : David K. Mulliner Helminthoglypta tudioulata (Binney, 1843) (Figure 2) was collected by Richard in numerous locations in the county: Bonita; Black Mountain Road, Mira Mesa; Stelzer County Park, Lakeside; and Oceanside. The figured specimen was found in Oceanside living under a log on the north side of the San Luis Rey River near Camp Pendleton. According to Dr. Barry Roth, who identified the two species, both "are natives and well-known from San Diego County." Page 95 THE FESTIVUS Vol . XXI (10): 1989 Figure 2. Helminthoglypta tudiculata (Binney, 1843). (SDNHM 93399). 25.2 mm max. diam. Leg. R. Cerutti, March 15, 1988. Location: north side of San Luis Rey River near Camp Pendleton, CA. Photos: David K. Mulliner ACKNOWLEDGMENTS Richard Cerutti brought the specimens of the two species to my attention, Barry Roth provided the identifications and David K. Mulliner took the photographs. CORRECTIONS: In Larry Buck’s March 1989 article, "A Trip to Puerto Escondido" [Festivus XXI (3) :26-27 ] a species listed from that area as Oliva kaleontina Duclos, 1835, is actually 0. spicata Roding, 1798, and the identification of a dead collected Cypraea robertsi (Hidalgo, 1906) is doubtful since the shell is very worn. In a June 1984 paper by Jules and Carole Hertz entitled "Collecting in La Paz" [Festivus XVI (6) : 66-70] the species listed as Corall'ioph'ila nux (Reeve, 1846) is actually Coralliophila parva (E.A. Smith, 1877). The authors of the two papers are indebted to Carol Skoglund for the correct identifications of the species. Page 96 THE FESTIVUS Vol . XXI (10): 1989 BOOK NEWS COMMON AND SCIENTIFIC NAMES OF AQUATIC INVERTEBRATES FROM THE UNITED STATES AND CANADA: MOLLUSKS. By: Turgeon, D.D., A.E. Bogan, E.V. Coan, W.K. Emerson, W.G. Lyons, W.L. Pratt, C.F.E. Roper, A. Scheltema, F.G. Thompson, and J.D. Williams 1988. American Fisheries Society Special Publication 16. vii + 277 pp. , 12 color pages. Price: $30 clothbound and $24 paperbound Within the past year students of malacology have benefitted by the publication of two taxonomic surveys which are essential additions to any reference library. The first of these is Kay Vaught's Classification of the Living Mollusca (reviewed in FESTIVUS 21(4) :29), a categorization of the entire phylum to the generic level. The second contribution is a compilation of the common and scientific names of the mollusks from the United States and Canada (excluding Hawaii). The result of a collaboration between the American Fisheries Society and the American Malacological Union, this is the first volume in a series on the North American invertebrate fauna, a similar volume on decapod crustaceans is due shortly. The many contributors to this work have attempted, by consensus, to standardize the use of common or vernacular names of mollusks, which are arranged according to their scientific counterparts in a phylogenetic checklist. The importance of establishing this systematic consistency is discussed by the authors who observe that "uniform vernacular names of mollusks are needed not only for commercial shellfish, but for amateur collectors and the industrial trade, for aquarium specimens, for the import or export trade of mollusks or molluscan products, for legal documents, for govermental listing or threatened and endangered species, for shell crafts and for popular or scientific writing." About 5,700 species are included in the survey. Technically, this work is very well organized with an alphabetical and phylogenetic family list as a preface, the main checklist of species, and a comprehensive index. As window dressing, a 12-page "Portfolio of Mollusk Diversity" follows the index. The checklist is useful not only for the common names provided but also for the author/date citations after the taxa, a feature lacking in some of the popular works used at present. Not all the species listed have common names, for some taxa are either poorly known, rarely encountered, or minuscule. This is an evolving document, subject to many future revisions. Readers are encouraged to respond with comments and to participate in the updating process. An updated edition is due in five years. This work did not intend to impose scientific names, but even the choice of some of the higher taxa (family or generic names) for phylogenetic purposes could be questioned. In any event, the potential of systematic disputes is a perfectly normal by-product of comprehensive surveys and does not detract from this work's value. On a lighter note, vernacular names are an interesting resource in their own right because they not only describe obvious aspects of an organism but reflect the social heritage of various regions in the country. The book is an entertaining source of molluscan trivia. While some of the names are the obvious ones we all learned initially, others are quite bizarre, especially when taken out of context (or out of region). Anthropomorphic names abound, like the "bull roarer cyphoma", "greedy dovesnail" or "rude barrel bubble". Names can make their subjects sound quite formidable, like the "clawed armhook squid" or "warty jumping-slug". Others can be mysteriously ambiguous. Ever hear of the "threehorn wartyback" or the "fat pocketbook" (Hint: they are in the same family as a "fatmucket", a "turgid blossom" or a "Texas pigtoe"). Imagine these in legal documents or the Congressional Record and one sees why taxonomy can even be fun. Henry W. Chaney Page 97 THE FESTIVUS Vol .

Vol. XXI (10) : 1989 THE FESTIVUS Page 98 SAN DIEGO SHELL CLUB MEMBERS DIVE SAN MIGUEL AND SANTA ROSA ISLANDS LARRY BUCK 2534 Via Pisa, Del Mar, California 92014 This past August a group of eleven members of the San Diego Shell Club traveled to the nutrient-rich waters of San Miguel and Santa Rosa Islands off the California coast for a fantastic dive trip. We left Santa Barbara in the wee hours of the morning on board the luxurious (by dive boat standards) dive boat "Conception" for a day and a half’s diving. On the first day there were four daytime dives starting at 9:00 A.M. and a fifth, a night dive, after digesting a beautifully prepared filet mignon feast. Our food on board was delicious and always available. The excellent service by skipper and crew made our diving comfortable despite the 56° F water temperature. We all made use of the two hot showers on deck between dives. We were unable to dive some of the deeper, more taxing areas due to our skipper’s apprehension over the ability of some of the other divers on board. I can't say I could question his judgment. On the second day we were able to dive off Santa Rosa Island just to the south of San Miguel, where the water temperature was 62° F. I was enthralled by the richness of the invertebrate life off San Miguel Island. The species’ colors and sizes were like the colder-water forms I'd seen north of San Miguel Island in central and northern California waters and south in Baja California in the isolated area from Punta Bonda to Santo Tomas. San Miguel is similar to these areas in that the currents bring an upwelling of colder water to shore. Some of the more noteworthy mollusks encountered during our dives were: Ceratostoma foZiata (Gmelin, 1790) (with the most beautiful specimens from San Miguel' waters); Pteropurpura macroptera (Deshayes, 1839); MaxueZZia santarosana (Dali, 1905); Ocenebra barbarensis (Gabb, 1865) (Figures 1 and 2); 0. foveolata (Hinds, 1844) (Figures 3 to 6); 0. beta (Dali, 1919); Cypraea spadicea Swainson, 1823; CaZZiostoma gZoriosum Dali, 1871, and C. Zigatum (Gould, 1849) on rocks; C. canaZicuZatum (Lightfoot, 1786) on kelp fronds (one specimen 34.8 mm, almost record size); along with very large (to 63.8 mm) Norrisia norrisi (Sowerby, 1838); very large Mitra idae Melvill, 1893; and the ever-present and very large Astraea gibberosa (Dillwyn, 1817); the large Cryptochiton stelleri (Middendorf f , 1847); Tegula regina (Stearns, 1892); very large and clean KeZZetia keZZetii (Forbes, 1852); RaZiotis rufescens Swainson, 1822, on which the Ocenebra species were found; Crassadoma gigantea (Gray, 1825); and the frilly bivalve Irus lamellifer (Conrad, 1837). Several small dead RaZiotis assimiZis Dali, 1878, were also found. However, I think their habitat is deeper than the area in which we were diving. Some Epitonium species were found but are not yet identified. Many of the Cypraea spadicea seen at north Santa Rosa Island showed signs of damage and had an almost white overglaze. And the large Astraea gibberosa found at San Miguel always had the spires eroded. One of our chief objectives was the gastronomical treat RaZiotis rufescens which were collected, much to our delight. I think it is important to stress that although we were able to take advantage of San Miguel's sizeable abalone population, it is in urgent need of protection from over-exploitation by sport and commercial divers. Soon the waters of San Miguel will be depleted of its abalone just as the rest of Southern California unless measures are taken to regulate the taking of abalone.

Remember to participate in the traditional shell gift exchange. Bring your gift- wrapped shell to place under the tree. On the outside place only general locale i.e. Caribbean, eastern Pacific. Numbers will be drawn and those bringing a shell gift will choose one from under the tree. Master of Ceremonies Ron McPeak will install the officers for 1990 and follow by introducing the slide program "What was new this year?" Bring about 6 to 8 pertinent slides and be a part of the show. The Christmas party is a time to welcome the season with your friends. Come and join the fun. Guests are welcome. For details and map see the last page of this issue. DUES ARE DUE This is the last issue of The Festivus for 1989 (no December issue) and time to announce that dues are due by January for the year 1990. The Club year has always been from January to December and with high printing and postage costs, the Club can no longer continue to send issues to any but paid-up members. Please send your dues to the Club address or pay to Margaret Mulliner, treasurer by the January meeting. FROM THE MINUTES - SAN DIEGO SHELL CLUB MEETING - October 19, 1989 Our October 19th meeting was outstanding with Dave Mulliner in the spotlight. His slide show lecture was on his travels throughout the Philippines. Dave's gift as a narrator made us feel as if we were right there, examining tropical fruits ashore or adjusting our face masks as we splashed beneath quiet lagoons to marvel at exotic and colorful marine fauna. And we got a close look at the magnificent shell collection of Victor Dan. Our second speaker, Jeremy Hutsell shared with us his shell collecting trip in Puget Sound and he brought some eye-catching specimens he'd gathered there. Jeremy's talk revealed some of the rewards of shell collecting in Washington's cold waters. A mini book auction followed the talks and three fine volumes for the conchologist ' s bookshelf went home with lucky Club members. After the refreshment break with cookies supplied by Ron McPeak and Kim and Don Avilez, Larry began the business meeting by announcing the slate of officers for 1990 as selected by the nominating committee. They are as follows: President: Kim Hutsell Recording Secretary: Wayne Reed Vice President: David Mulliner Corresponding Secretary: Rick Negus Treasurer: Margaret Mulliner Editor: Carole Hertz Nominations from the floor will be entertained at the November meeting prior to the election of officers. The new officers will then be installed at the Christmas party. The shell drawing was won by Margaret Mulliner.

But, since most diving activity takes place relatively close to shore, the marine life a mile or so offshore goes largely unobserved by divers. On July 4th of this year, Mike Johnson and I decided to make a dive at a depth of between 100 and 110 feet about a mile and a half straight out from Casa Cove to see what was there. I was surprised to find a rather large population of Astraea gibberosa (Dillwyn, 1817) and Pteropurpura vokesae Emerson, 1964. Most of these specimens, however, were either heavily encrusted or badly eroded and not worth collecting. It was quite a contrast to the clean, perfect specimens we had observed at the same depth six miles to the south off Point Loma. Just before our ascent, I spotted a large limpet-like animal clinging to the side of a rock. Uncertain of its identity, I collected the specimen and brought it to the surface for closer examination. With assistance from Carole and Jules Hertz, the specimen collected off La Jolla was identified as Scelidotoma bella (Gabb, 1865) (Figures 1 and 2). McLean (1966) Figures 1 and 2.

Mulliner Page 104 THE FESTIVUS Vol. XXI (11): 1983 proposed the genus Soelidotoma for the species formerly known as Emarginula bella Gabb. He illustrated a juvenile specimen (4.9 mm long.) from Carmel, California and the mature holotype (51 mm long.) of Sub emarg inula yatesi Dali, 1902, a synonym of Soelidotoma bella3 from Monterey, California. The specimen figured (Figures 1 and 2) is the first example of this rare species I have observed in eight years of diving along this coast. This immature shell measures 36.1 mm in length, 26.2 mm in width and approximately 12.8 mm in height. The shell of S. bella is solid, translucent-white and highly sculptured with strong, well-defined ribs radiating from the apex. Between the stronger ribs there are three smaller ribs, one moderately strong rib flanked by weaker ones. The apex is situated slightly posterior of the center and curls toward the posterior. From the apex to the anterior end, there is a single rib much stronger than all the rest. This shows up as a channel or groove on the interior of the shell becoming very pronounced at the margin. None of the other ribs show on the interior until they reach the edge of the shell, giving it a crenulated appearance. The rest of the inner surface is smooth except for the muscle scar, which is slightly depressed. The animal of Soelidotoma bella is a light, creamy yellow in color with black eyes on the end of the eyestalks and shows no other color or markings. This specimen extends the reported southern range of S. bella from San Pedro (Abbott, 1974) to La Jolla, California. In a note from Dr. James H. McLean, he mentioned that specimens from Punta Banda and Cabo San Martin, Baja California, Mexico, are in the Malacology Collection of the Los Angeles County Museum of Natural History. ACKNOWLEDGMENTS I would like to thank Carole and Jules Hertz for locating the literature on this species and also Dave Mulliner for photographing the shell. LITERATURE CITED ABBOTT, R. TUCKER 1974.

HERTZ** *2415 29th Street, San Diego, **Associate, Department of Malacology, Los Angeles California, 92104 County Museum of Natural History, 900 Exposition Blvd., Los Angeles, California 90007 Color photographs and information on three species of typhids were received by us in a letter from Mr. Peter Ryall of Austria. Two photographs of three shells which he labeled Pterotyphis sp. were of particular interest to us (Figures 1 and 2). They show three crabbed specimens of Pterotyphis pinnatus (Broderip, 1833) collected off the coast of West Africa: (a) the fragment, 5.9 mm from Sekondi Bay, Ghana, Feb. 12, 1988 (b) 11.1 mm, in 12 meters off Takoradi Harbour, Ghana, Jan. 17, 1986 (c) 7.0 mm in 15 meters off Busua Island, Ghana, Jan. 24, 1986. This extends the known distribution of this species across the entire Atlantic Ocean. Pterotyphis pinnatus 3 type of the genus, was originally described without a type locality. This species has previously been reported (as Pterotyphis fordi Pilsbry, 1943), living in shallow intertidal waters in the Bahamas.

HERTZ Associate, Department of Malacology, Los Angeles County Museum of Natural History, 900 Exposition Blvd., Los Angeles, California 90007 On October 15, 1989 on a -1.2 foot low tide, I found two specimens of Mitvella aurantiaoa (Dali, 1871) (Figures 1-3) living intertidally just above the lowest tide zone. They were on the underside of a large rock covered with worm tubes and overlaid with a tunicate (probably Didemnum) . The two animals were on the tunicate. This was the first time I had seen this species intertidally. It is usually found subtidally (McLean, 1978). The shell is pale yellow-brown covered by a crazy-quilt of spiral brown lines and just below the suture a row of white bars. The animal has a cream-colored proboscis girdled by two black rings and has rows of white dashes along its length. The tentacles are also cream colored with black rings and the black eyes are at the base where the flesh becomes dark brown to black along the top of the head. The foot is cream with dark brown markings above and random dots of blackish-brown on the base. The operculum is corneous and a light amber color. My appreciation to David Mulliner who kindly photographed the animals. LITERATURE CITED MCLEAN, JAMES H. .. . © 1978. Marine Shells of Southern California. Nat. Hist. Mus.
