ADAMS. 1853 BY ANTHONY D'ATTILIO Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P,0. Box 1390, San Diego, California 92112 I recently requested of Ms. Kathie Way of the British Museum (N.H.) the type or typological material of the coralliophilid species, Murex pagodus A. Adams, 1853, commonly referred to as Latiaxis pagodus (A. Adams, 1853). Ms. Way graciously sent photographs of the holotype herein illustrated as Figures 1 and 2. Those photographs were a startling surprise. I realized that the holotype is a different species than the Latiaxis pagodus of authors illustrated in many works of this century. Figure 3, illustrated here from Kira (1962, pi. 26, fig. 13), shows a specimen of Latiaxis pagodus of authors, not of A. Adams. Fig. 1. Dorsal view of Fig* 2. Apertural view of holotype of Murex pagodus holotype of M. pagodus. A. Adams, 1853. BMNH Reg. No. 1982294 Fig. 3. Latiaxis pagodus of authors, reproduced from Kira (1962, pi. 26, fig. 13). In D'Attilio and Bertsch (1979) the numerous generic taxa in Coralllophilidae were reviewed. It was proposed in that paper that those species of Coralllophilidae having a fusoid form with a spinose shoulder keel (with or without similar keels on the body) be placed in Babelormrex Coen, 1922, type species O.D. Fusus habelis Requien, 1848. The popular usage of Latiaxis is based on a misconception. The true Latiaxis is a non-fusoid shell with an almost completely flattened spire with the final half of the body whorl detached. THere is a row of strongly recurved, short, broad spines at the shoulder keel and only extremely fine scabrous striae (almost microscopic) on the Vol. XV(1) 1983 THE FESTIVUS 3. body whorl. The type of Latiaxis is Latiaxis mawae (Griffith and Pldgeon, 1834). Figure 4, reproduced from D'Attilio and Bertsbh (1979) shows a specimen of Lattaxis mawae. Thus, Murex pagodas A. Adams, 1853, customarily referred to as a Latiaxi-S should be con- sidered a BahelomuTex. Recently a specimen of Bahetomuvex from the Bohol Straits, Cebu Island was donated to the San Diego Natural History Museum [SDNHM7950] . This specimen appears to be Babelomurex pagodas (A. Adams, 1853). It is illustrated here in Figures 5 and 6. Unless an existing name is available for Babetomurex pagodas of authors, not of A. Adams, a new name will be needed for the former. Fig. 4.

Kosuge' s figures of the holotype are reproduced here in Figures 7 and 8. A specimen figured by Habe (1964) as Latiaxis diadema (A. Adams, 1854) also bears comparison to this complex. It is figured here as Figure 9. Fig. 7. from Kosuge (1979, Fig. 8. from Kosuge (1979, pi. 2, fig. 9) pl. 2, fig. 10) Latiaxis ( Laevilatiaxis ) aristatus Kosuge, 1979 Fig. 9. Latiaxis diadema (A.

MYRA KEEN* 2241 Hanover Street, Palo Alto, California 94306 The proper setting for a discussion of the books Linnaeus might have used would be the rare book room of some library, where a selection of priceless old volumes could be laid out side by side, so that their texts and illustrations could be com- pared. Photographs of the books are a poor substitute, lacking color and texture and rarely being of the same size. Therefore, I will compromise by making the first part of this paper description — something about the lives and work of the men who, before Linnaeus, contributed most to malacology — the second part a commentary on those books available to me for photographing. Linnaeus stands as a human milepost in the history of zoology. By common consent, the tenth edition of his "Systema Naturae”, published in 1758, is taken as the starting point for our modern nomenclature. Probably all of us have wondered at some time how he accomplished so much. I remember, as a beginner, asking Mrs. Oldroyd about this. I said he must have had a tremendous store of knowledge, for 1 imagined that he had discovered all the species we credit to him as author. Of course this is a long way from the truth. He did make a few short expeditions, and he did acquire a large collection, but it was mostly of plants and animals brought or sent back to him by his students. His real contribution was twofold: the idea of a consistent two-name (binomial) naming system and a way of indexing, as it were, the literature of the past. The actual books that Linnaeus cited did not date back much over 200 years. There were 40 that he mentioned in his chapters on mollusks, and practically all of these had illustrations. The very earliest book of all — in fact the one in which the word 'mollusk’ was coined — Linnaeus did not mention, though no doubt he was well aware of the work of Aristotle, especially his "History of Animals." This was written around 340 B.C., when Aristotle lived on the Greek island of Lesbos. For 1800 years this work was largely forgotten, but during the Renaissance it was rediscovered. Men had begun, in this revival of learning, to look at the world with fresh eyes as early as the 13th century A.D., but the natural sciences were slow in getting under way, and the first books with pictures did not appear until the 1550s. Then there were three, almost simultaneously, by Belon, Rondelet , and Gesner. Pierre Belon was born in 1517 in France. He studied in Germany and while there talked with Martin Luther. His longest trip took him south through Europe to Turkey and Egypt. On the way back his boat was captured by pirates and his collections lost. However, he went to study with Rondelet (or Rondeletius) , a famous naturalist- physician. Putting his notes in order, he published a 450 page book, "De Aquatilibus , " in 1553. Dealing mainly with fishes of the Mediterranean, it did make one important contribution — Belon divided the animal kingdom into two great parts, those animals with blood and those without blood. These two divisions we still recognize but now we stress rather the skeleton: vertebrates and invertebrates. The woodcut text figures of this book are rather crude but recognizable. Gephalopods make up more than a third of the mollusks Belon mentioned. We cannot quibble, for Aristotle himself used the term ’mollusk' only for cephalopods and used other names for the bivalves and snails. *A paper given at the annual meeting of the Western Society of Malacologists , June 22, 1982. 6. THE FESTIVUS Vol. XV (1) 1983 We can wonder whether the names Aristotle used for shell genera had the same meaning for him that they do for us — Purpura^ Ealiotis, Nevita, Solen, Tellina. Belon had a broader concept of species than we do. His first gastropod figure he called "Patella or Lepas , " the second, "Patella maris rubra," and the third, "Patella major." We now recognize Patella as a genus of limpets and Lepas as a genus of barnacles. His first figure is of a true Patella, but the second is a chiton, the third a Haliotis. The real puzzle among Belon *s figures is one he called "Purpura," actually a Strombus pugilis from the Caribbean area. How could such a shell get to Europe only 60 years after the discovery of America? Is it possible that one of Columbus’ men carried it back? Rondelet (or Rondeletius) , with whom Belon had conferred, was a Huguenot physician who was born in France in 1507. His father had disinherited him when he went into medicine instead of the clergy, but he seems to have done well nevertheless. He jour- neyed as far as Rome at one time. Like Belon, Rondelet gave his attention mainly to fishes. His great work on the fish of the Mediterranean appeared in 1554. Comparing the names he used with those of Belon one realizes how little grasp these early workers had of relationships. The Ealiotis Belon called "Patella major" Rondelet called "Auris marina," which at least preserves the root meaning of Ealiotis, "sea ear." Like Belon, he used "Lepas" for both a limpet and a chiton. The name "Chama" he used for four different clams. In this book on fish he figured some 130 kinds of mollusks. Third among the early three men was Conrad Gesner, a celebrated name in zoology. He compiled much information and tried to Illustrate all of the known plants and animals. He was a Swiss Protestant. The molluscan section of his "Historla Animalium" was almost entirely taken over from Rondelet, but he rearranged his topics in alpha- betical order, to facilitate reference by the reader. There is a 50 year gap between these three and the next work, that of Aldrovandus, 1606, an Italian professor at the University of Bologna. He too was a compiler, but he made more effort to be critical of his sources, and he laid much stress on good figures . From 1675 onward, books were more elaborate and more numerous. Foremost, especially for its Influence on later authors, was the work of an Englishman, Martin Lister. His first great work, a Natural History of England, appeared in 1678, and his major work, the Hlstoria Conchyliorum (History of Shells) in 1685 to 1692. This was divided into what he called Books, Sections, and Headings, somewhat analogous to our modern Orders, Families, and Genera. There was no text, but on each of the more than 1,000 plates were engraved the names and brief descriptions. These were numbered consecutively. The engravings were exquisitely done by Lister's two daughters, Anna and Susanna, each of whom developed an individual style. Buonanni, an Italian, published a book in somewhat the fashion of the mediaeval schoolmen, in two editions, an Italian, 1681, and a Latin, 1684. The tedious and mediocre text is a series of essays on such topics as "Why is the operculum round?," "Why do some shells have color?," etc. The woodcut plates are rather skillfully done, and an amusing use of shells is shown in several plates, where they are arranged in designs, mostly human faces. A second truly great work of this period, surpassing even that of Lister in many ways, was by a German, George Rumphlus, who became a clerk for the Dutch East India Gompany on the spice island of Ambolna, at the age of 25. For 17 years he collected and studied the strange plants and animals of his new surroundings, gloating over them and trying to record them on paper. After tragic losses — the first his eye- sight, then his wife and daughter, who had been his helpers, in an earthquake; then, by fire, most of his original sketches. However, his employers began to help him, and artists made new drawings and two copies of the manuscript for the book. The first copy, sent to Holland, was lost at sea when pirates sank the ship, but the second copy, sent later, got through and created favorable comment in Amsterdam. Finally, in 1705, three years after Rumphlus had died, the work appeared in print. It Vol. XV(1) THE FESTIVUS 7. '''■fJP'" . immediately took rank as the most remarkable book of its time, with original descriptions of hundreds of new species, which even by today's standards would be regarded as of good quality. Rumphius was far and away ahead of his contemporaries and his predecessors on several counts — his descriptions were effective; his illus- trations were excellent; he had a feeling for sound classification; he had a first- hand knowledge of the forms, their habits, and practical uses; and, most important, an awareness that locality information is vital. Linnaeus was deeply indebted to Rumphius for this as well as for several other conventions, and he took over Rumphius' nomenclature with only slight changes. Twenty-three of the 40 works cited by Linnaeus were published after 1700. This was the era of exploration, and the amassing of shell collections not only became a pleasant way of enjoying scientific pursuits but also something of a status symbol. Three books of that period that contributed to human knowledge were by Gualtieri, by Klein, and by Adanson. Gualtieri 's handsome folio volume, an index of shells, published in Florence in 1742, emphasized the Mediterranean fauna. Klein attempted a new classification, but his illustrations were rather below standard. 1 would like to mention the work of Adanson, whose book on the natural history of Senegal, West Africa, appeared in 1757. Linnaeus, un- fortunately did not list it, perhaps did not even know of it. Had he seen and studied it, his classification would have been much improved. This brings us up, then, to the time of Linnaeus himself, that cardinal year 1758. No copies of the three earliest works he cited were available to me for photographing. The earliest exhibit I have is a plate from a little book dated 1616, by an Italian naturalist, Fabius Golumna (or Golonna) (Figure 1) . This was a two- fold treatise, one part on Purpura, the mollusks from which royal purple was derived, the other on other invertebrates, especially mollusks. Notice the names that are used. The shell at the upper left, which we would call a TrochuSj is labelled as "Turbo exoticus," and the limpet is called "Lepas,: a name we now apply to the goose barnacle. Figure 2 shows the title page of a second edition published in 1675. One feature of this edition is a tabular summary (Figure 3) that is a sort of crude classification. It is mostly in Latin, but occasional names are in Greek. Some of these, like the grandiloquent name for an ark shell — "polyleptoginglymus" — were taken over by later pre-linnean authors. Philip Garpenter had a caustic footnote about such practices. Notice that no real name is given to the bivalve at the right (now known as Cardium oostatum) unless "Bivalvia muricata" is so intended. A good example of what most museums of the time probably looked like is given in the frontispiece of the next book, by Ole Worm, 1655 (Figure 4). Specimens and curiosities of many kinds are distributed wherever there is space. Near the left wall is a chair made from a whale vertebra, and along the right wall are shelves with labelled boxes. Some boxes have stones, some metals, and one is "Gonchylia," shells. Fig. 1. Fabius Golumna, 1616. 8.

THE FESTIVUS Vol. XV(1) 1983 Contrast the exactness, however, of the Lister drawings with that shown in Figure 8, published the same year, 1685. It is from the book by Buonanni who was more of a philosopher than naturalist. Some of his plates show a touch of whimsy (Figure 9) , the use of shells in design. Buonanni' s second, more serious work (Figure 10) , the Museum Kircherianum, appeared in 1709. It still does not approach the quality of Lister. The figures, however, were of service to Linnaeus.

Vol. XV(1) 1983 THE FESTIVUS LL. Figure 11 is of the cover of Stanford's copy of Rumphius, sadly tattered but mute testi- mony to the heavy use this fine leather- covered volume must have received in the two and a half centuries since it was printed. We hesitated to have it rebound lest we lose some part of the broken spine. The frontispiece of the book (Figure 12) was done by Rumphius' son Paul — a portrait that poignantly reveals his father's blindness. A sample plate (Figure 13) shows the quality of illustration that Rumphius achieved, even under his handicaps and bad luck. The text gives a wealth of in- formation about each kind illustrated — locality, habitat, uses made by the native peoples, and some comparative notes on mor- phology. Commonplace as this would be today, such detail was not attempted by other natur- alists of that time. In his Index Testarum Conchyliorum (Index of Shells), 1742, Niccolo' Gualtleri, an Italian physician, set a high standard for artistic quality. Like some of his contemporaries, he began his folio work with an allegorical front- ispiece (Figure 14) . Only one versed in mediaeval mythology could get the significance of all this, but it makes a showy picture. The next figure (Figure 15) shows part of one plate and its accompanying explanation. Fig. 13. Rumphius, sample plate. Fig. 14. Gualtleri, 1742, frontispiece. u. THE FESTIVUS Vol. XV(1) 1983 The book is so large that not all of both pages can be gotten in and be legible in a reproduction. Notice the background shad- ing, which gives a sense of realism to the shells. The nomenclature of the caption is typically polynomial — major divisions by section and "genus,” each numbered. An apparently binomial name ("Concha pectinata") refers to the species, and there is a description of sorts. If two or more figures of similar forms occur on one plate, both may be cited by the same binomial and differen- tiated by the descriptive terms that follow. Notice a reference to an earlier figure, one by Rondeletius. Linnaeus was not then the first worker to use the earlier literature in this way. The first edition of Desallier d’ Argenville's work (Figure 16) also appeared in 1742, but it is not so fine as that of Gualtieri. The plates are mixed and crowded. Notice that under Murex he includes shells that we would place in at least six other genera. Naturalists had not yet begun to make fine discriminations. Jacob Klein, in 1753, attempted to bring order into malacology by introducing a new system (Figure 17). He has had somewhat of a following among a few European workers who feel that he should be credited with the new names he devised even though they appeared before the cardinal starting date of 1758. A sample section of his tabular analysis is given here (Figure 18). At first glance this looks binomial, but Fig. 16. Argenville, 1742, sample plate T r N T A M F.

His plates are of indifferent quality, with many reversed figures (Figure 19) . 1 would like to show you a plate or two from Adanson, also 1757, to show the contrast, but alas, Linnaeus did not cite the work and probably did not see it. Linnaeus did, however, cite one work that appeared in 1758, by Regenfuss, published in Copenhagen (Figure 20) . If the source from which 1 copied this figure was accurate, we might possible have the first use of color in portraying shells. But these figures may have been colored by some owner of the book and thus may not have been so done in the original printing. All color work at that time would have had to be hand applied. Linnaeus himself is shown in his later years (Figure 21) , when he was Carl von Linne, recipient of royal favors and the acclaim of the scientific world. The book that brought him this recognition is called "Systema Naturae per Regna tria Naturae...” (Natural System for the Three Kingdoms of Nature) . It is a small book, about the size of a modern Fig. 19. Klein, 1753, sample plate. Fig. 20. Regenfuss, 1758, [shown here in black and white] Fig. 21. Linnaeus, portrait. Vol. XV(1) 1983 14.

I adnata ttibiil..fa itifcrnc clanfa Fig. 22. Linnaeus, Systema Naturae, 1758, Classification, of Vermes novel, written entirely in Latin, with no illustrations. The introductory matter consists of some dedication pages and a tabular classification in which the Animal Kingdom is divided into six parts, four being ver- tebrate groups — mammals, birds, amphibians, and fish. The two invertebrate divisions are Insecta and Vermes — insects and worms. The Vermes (Figure 22) are comprised of five groups, and our present-day Mollusca are scattered among three of these, mainly in Testacea. His Intestina are mostly worm groups, but he did put the bivalve Tevedo here. Linnaeus' Mollusca are soft-bodied animals, again mostly worms, but one does note the slug Limax^ the nudibranchs Doris and Tethys^ and the cephalopod S'epia. Under Testacea there are four divisions — Multivalvia (chitons and barnacles); Bivalvia (pelecypods) , with 14 genera; Univalvia Spiralia (cephalopoda and most gastropods), another 14 genera; and three genera of non-spiral Univalvia {Patetta, Dentatiunij and the annelid Serpula) . This classification betrays a lack of experience with living marine invertebrates. It is obviously the work of a botanist who was trying to extend an ingenious system beyond the boundaries of a familiar area. Tf that were all there was to Linnaeus' work, we could dismiss it. However, the real heart of his system comes to light in the text that follows, not in the major classi- fication. After all, a classification is and should be subject to change with changing concepts. His great contribution is the codification of generic and specific names, so that one name applies to one organic kind and to no other. For example, under each genus we find a brief generic diagnosis describing the — shell. Then the species are listed by name and serial number, mkmi- hmn.ia ..m„„ - m u\n . n -i i \ . with a one or two line descrip- tion and a list of references. Take, for instance, Ustrea (Figure 23) . The animal is a Tethys [did he really ever look at one?] ; the shell bivalve, and the hinge edentulous. Then he lists several species that form a group, although he had not hit on the idea of subgenera. This first group is "Pectines auric- ulata," eared comb-ribbed shells — a distinct group that Muller 20 years later made a separate genus, Pecten. Linnaeus' first species is Ostrea maximus , which later was made the type of Pecten. The type of Ostrea was designated by the ICZN as 0. eduZis. h, /».:>/ I.lln /]■//., hiwilvi-^.' iiiv.iK is. fnliauriui.

The animal is, he says, a Limax [that shows how naive he was where animals are concerned] , the shell univalve, with con- volute coiling, the aperture effuse, the colu- mella smooth. The first species is C. marmoneus , which was later designated as type. For references he cites figures in Buonanni, Gualtieri, Rumphius, Argenville, which are all familiar names to you now, and he says the habitat is Asia, vjhich is reasonably correct. Linnaeus' signal contribution was, then, a flexible plan for classification that was based on an inflexible central principle of binomial nomenclature. This could cut through and unify the diverse attempts of his pre- decessors. It had the effect of revolution- izing the whole domain of natural history study. Editor's Note: David K. Mulliner, Festivus staff photographer is responsible for all the black and white prints made from Dr. Keen's slides. We are grateful for the hours of time he devoted to making the best possible prints. \ 1 KMI > i I .S I A( l .A. Nautilus. /.-/ /> , jt. li// /III-,/ HI n.ontibus nojlris (al~ .

THE FESTIVUS Vol. XV(1) 1983 FROM THE MINUTES SAN DIEGO SHELL CLUB MEETING - 19 NOVEMBER 1982 BY PAT SAGE Calling the meeting to order at 7:45 P.M., President Martin Schuler welcomed guests and new members. Vice President Bill Perrin introduced the evening's sub- stitute speaker, Twila Bratcher, pinch-hitting for the scheduled speaker who was called out of town on short notice. Twila 's slide presentation was titled, "Neptune's Art" and highlighted nature's nautical designs and colors. Operating on a short fuse, Twila is to be commended for an entertaining and interesting program. Dave Mulliner showed slides of September's "Out of this World" party, and several members gave briefings on recent shelling trips that were in some cases preempted by bad luck and bad weather. After the refreshment break, the December party was discussed at length; the October minutes were corrected and accepted; the slate of officers as presented by the Executive Board was approved and voted for unanimously. [The officers for 1983 are listed on the masthead of this issue. Editor] . The Library Committee reported that The Festivus has been hardback bound in two volumes. The shell drawing was won by Dave Mulliner and the meeting adjourned at 9:30 P.M. THE ANNUAL CHRISTMAS PARTY BY JOHN SAGE The Club's annual Christmas party was held in the Naval Station Officer's Club on December 11. Members found the new environs a pleasant change, and rounded out the evening dancing to a mellow band. June King contributed her talents again to the lovely table arrangements, and with cocktails, good food, good friends and great shell exchanges, the evening was a "f un-f or-all .

THE FESTIVUS Vol. XV(2) 1983 FROM THE MINUTES SAN DIEGO SHELL CLUB MEETING - 20 JANUARY 1983 BY JOHN SAGE Ringing in the new year's Club activities, President Pat Sage called the meeting to order at 7:45 P.M. New members and guests were welcomed and Bill Perrin intro- duced the evening's program, "The Joys of Working at Sea" presented by Club member, Hugh Bradner. Members were treated to a vicarious journey through parts of the Pacific on a scientific seismic study. In spite of certain hardships and inconven- iences, there were the residual rewards of beautiful places, people, and shells. ' On a sad note, Pat read a letter Informing the membership of the death of William E. Old, Jr. [See below]. After the refreshment break a motion was made and carried to accept the minutes from the November meeting. Wally Robertson reminded members that 1983 dues are now due, and Abbott and Dance's COMPENDIUM OF SEA SHELLS is available [See Review on p.28]. Marty Schuler, Publicity Chairman, has made arrangements for several public service announcem.ents pertaining to Club activities. The Bradners are again hosting the annual Club Auction/Potluck on April 30, 1983. It was noted that early donations would help expedite the preparations for this event. The Christmas tree and trimmings used for the 1981 Christmas party are missing. It was requested that all present at that party please check their storage spaces in search of . . . Dave Mulliner showed the 1982 Christmas party slides. Ms. Marge Lindall won the "lOU" shell drawing and the meeting was adjourned at 9:00 P.M. The Club received the sad news of the passing of William E. Old. Jr., of the American Museum of Natural History, on December 31, 1982. Dr. William K. Emerson writes that the Museum is establishing the William E. Old Malacology Fund as a mem- orial to him. Contributions to the fund will be used to support the Department's malacology program of which Bill Old was an important part for the past 22 years. S FOR YOUR INFORMATION | I The Club's annual Auction/Potluck will be held on Saturday, April 30 at the home | of Marge and Hugh Bradner. It is now time to begin donating shells to the Auction — our only fundraising event.

Box 1390, S.D., CA 92112 | KURTZEBORN, Nancy A. 3780 Ash Circle, Salt Lake City, Utah 84109 Vol. XV(2) 1983 THE FESTIVUS 19 COLLECTING IN MAZATLAN BY JULES HERTZ & CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In March of last year we took our first trip to Mazatlan in Sinaloa, Mexico. As with most of our vacations, we try to combine shell collecting with the other more usual tourist type activities. In this case we had our doubts about the collecting. From reports through the years about the rapid growth of the city and the changes in the natural shoreline as well as the invasion of visitors; we were not confident that collecting there would be at all productive. But, as with other inveterate collectors we believed that where there's water there's hope. We stayed at a lovely hotel, the Playa Mazatlan, one of the first fine tourist hotels right on the beach. Our rooom was simple, spacious and immaculate with a balcony facing the water and Punta Cameron. Punta Cameroli (shrimp point) is a rocky outcropping with turnable rocks and sandy places just a short walk on the beach from our hotel. We were drawn to it at every low tide as if by a magnet. Even when we collected elsewhere, we made a late low tide courtesy call at Punta Cameron. We found it the most interesting collecting spot — even if it was convenient. Though we investigated some other collecting areas, a few extremely disappointing only one other, Isla Venado, was fairly rich and great fun. Isla Venado is one of several very small islands close to the shore off Mazatlan. We tried Venado because the transportation to it seemed an adventure in itself. We wanted to ride "Super Pato (Super Duck), a World War II landing craft converted to a bright yellow amphibious Surrey with the Fringe on Top. For eighty pesos we, along with a bunch of local teen- agers and tots and other tourists, made the approximately 20 minute voyage to Isla Venado. We were at least as fascinated with this craft as the little children who crowded around the pilot and observed the mysterious machinery which allows this tank-like vehicle to swim. Super Pato makes the round trip to Isla Venado three times daily, allowing passengers to go over on an early trip and return on any later one. On the last return ride the gentle ol^mer/pilot searched the island for stragglers before leaving , Isla Venado' s rocky shore made for slippery collecting. We found some species there such as Toni-oia fovbesii Carpenter, 1857 and Conus gladiator Broderlp^ 1833 that we didn't see at the other locations. We found Mazatlan to be friendly, beautiful and very clean with many sights both historic and scenic; good restaurants, a balmy tropical climate and an ambience that invites us to return. The species we collected in Mazatlan are listed in Table 1 in taxonomic order according to Keen (1971). In most cases. Keen's figure numbers follow the specific entries. Where changes in taxanomic placement were made by Keen & Coan (1975), these are noted in parentheses following the original Keen number. An asterisk following a number in parentheses indicates its placement in McLean (1978). In addition to sources noted in the Literature Cited, comparative material in the San Diego Natural History Museum was studied. Col. George A. Hanselman Identified the chitons and Mr. David K. Mulliner identified the opisthobranchs . 20. THE FESTIVUS Vol. XV (2) 1983 Specimens were collected at four locations as shown on the map in Figure 1, and are listed in Table 1 as follows: 1. Punta Cameron, 2. Playa Bruja, 3. Isla Venado, and 4. Camino Real. The Table also notes whether the species were collected live (L) or dead (D) . Pertinent additional remarks are included. Although we spent only a week in Mazatlan, we were able to find a large number of species intertldally . It appears that the intertidal fauna is still diverse despite the rapid growth in population and tourism. One species collected defied our efforts in identification and is shown in Figures 2 and 3. A second, shown in Figures 4 and 5, was also troublesome. We are indebted to Helen DuShane for identifying the species as O'patia mexioana Dali, 1908. Two other species, shown in Figures 6-9, have been tentatively identified but require additional study for verification. We are indebted to Mr. David K. Mulliner, Festivus staff photographer, for the photo- graphs of these species. Figure 1. Detail map of collecting areas in Mazatlan. Figure 2. Apertural view of unknown Figure 3.

Vol. XV(2) 1983 THE FESTIVUS 27. UPDATE ON hOLLUSKS WITH INDO-PACIFIC FAUNAL AFFINITIES IN THE TROPICAL EASTERN PACIFIC^ BY DONALD R. SHASKY 229 Cajon Street, Redlands, California 92373 For a number of years Dr. William Emerson, of the American Museum of Natural History in New York, has been publishing on the overlap between the Indo-Pacific and Panamic molluscan faunas. His last paper on this topic, Mollusks with Indo-Pacific Faunal Affinities in the Eastern Pacific Ocean, was published in THE NAUTILUS in 1978 [92 (2) : 91-96] . In it he listed 41 species of prosobranch gastropods and 7 species of bivalves with Indo-Pacific faunal affinities. Of these, only 10 species, all gastro- pods, were found within the continental shelf of the Panamic Province. He also listed 5 additional species of gastropods that are clrcumtropical . The rest of the 41 species that he listed are found on islands outside of the continental shelf, namely, the Galapagos, Cocos, Clipperton, the Revillagigedo , and Guadalupe. Dr. Emerson listed the following 10 species within the continental shelf. (He did not include the opisthobranchs in his paper) . 1. Conus ebraeus Linnaeus 6. Mitra mitra (Linnaeus) 2. Conus tessutatus Born 7. Quoyuta madreporarum (Sowerby) 3. Cypraea teres Gmelin 8. Terebra affinis Gray 4. Eeliaous troahoides (Deshayes) 9. Terebra laevigata Gray 5. Miorodaphne triotiodes (Dali) 10. Titisoania timaoina (Bergh) The 5 circumtropical gastropods exclusive of opisthobranchs are: 1. Chei-Zea equestris (Linnaeus) 2. Crepidula aouteata (Gmelin) 3. Cymatium parthenopeum (von Sails) 4. Cymatium pileare (Linnaeus) 5. Eipponix antiquatus (Linnaeus) In 1979, Dr. Hans Bertsch, now of the University of Baja California in Ensenada, published a paper in THE NAUTILUS 93(2):57-61 titled Tropical Faunal Affinities of Opisthobranchs from the Panamic Province (Eastern Pacific) . In it he cites 4 species of opisthobranchs found both in the Panamic and Indd-Pacif ic , 11 species that are clrcumtropical, 8 that are Caribbean, and 4 are listed as miscellaneous. The 4 species found within the continental shelf are: 1. Dolabelta auriauZaria (Lightfoot) 3 2. Berghia major (Eliot) 4 The 11 circumtropical opisthobranchs are: 1. Lohiger souverhii Fischer 2. Aplysia dactylomela Rang 3. Aptysia juliana Quoy & Gaimard 4. Aptysia parvuta Morch 5. Dotabrifera dolabrifera (Rang) 6. Stytooheitus tongiaauda (Quoy & Gaimard) Poriopsis viridis Pease Spurilla alba (Risbec) 7. Berthellina aitrina (Ruooell & Luckart) 8. Phyltiroe bueephata "Peron & Lesueur” 9. Cephatopyge trematoides (Chung) 10. Fiona pinnata (Eschscholtz in Rathke) 11. Glauous attantious Forster *From a paper presented at the Western Society of Malacologists meeting — 1982. 28. THE FESTIVUS Vol. XV (2) 1983 The purpose of this paper is to review the Indo-Pacif ic species that have been reported within the Panamic continental shelf since Emerson’s and Bertsch's last papers appeared, and to add additional unreported species of my own. 1. Phitippia vadtata (Roding) was taken at Gorgona Island, Colombia, and re- ported by Robertson (1979) in VELIGER 22 (2) : 191-193 . 2. In the April 1982 issue of THE NAUTILUS 96(2):42-45, Bertsch and Bibbey record Phenaoovolva brevirostri-s (Schumacher) from Panama. 3. PseudooypTaea adamsori'i'i Sowerby has been taken on several occasions in the Galapagos, but I here record it from La Plata Island, Ecuador, within the Panamic continental shelf. 4. Bizetielta shaskyi Radwin and D'Attilio, 1972 was described from the West American mainland [Proc. Biol. Soc . Wash. 85 (28) : 323-52] . I have collected a single specimen on Moorea, French Polynesia. 5. I have collected a single specimen of a small turrid at Taboga Island, Panama, that Dr. Virginia Orr Maes has identified as Kermia maculosa (Pease), Dr. Maes told me that the Philadelphia Academy has this shell from the Red Sea to Madagascar, Japan, and the Cook Islands. I have collected it in North Queensland, Australia and at Moorea, French Polynesia. 6. In 1969, Hamatani [ Pubis. Seto. mar. biol. Lab 17:171-174] described Cyli-ndrobulla y^pon'ica^ a sacoglossan opisthobranch from Japan. In 1971 [Pubis. Seto. mar. biol. Lab 19:111-117], Hamatani described another Cylindvohulla, C. califomi-ca from the Gulf of California. This was from material collected by Allyn Smith. After finding two very puzzling little shells at La Plata Island, Ecuador, I took them, this past February, to Dr. Keen for identification. She pulled out the Hamatani papers. Following this, I wrote to Dr. Evaline Marcus in Brazil, who referred me to one of her papers published in 1976 [Marine Euthyneuran Gastropods from Brazil (3), Stud, on Neotropical Fauna & Environ. 11 (1-2) : 5-23] . In it, she synonymizes the Brazilian Ascobulla ulla (Marcus) and Ascobulla californioa (Hamatani) with Asoobulla gaponica (Hamatani). Hence, we can include Asoobulla japonioa (Hamatani) as a circumtropical species . I would now like to depart a moment from the topic of my paper to call to your attention two items from recent publications. The first is the establishment of the genus Xandavovula in the Panamic fauna. This genus has previously been known from only 5 species; 1 European and 4 western Pacific. Bertsch and Bibbey (1982), in THE NAUTILUS 96(2):42-45, described Xandavovula hammesi from Cebaco Island on the Pacific coast of Panama. Also of interest is an item that appeared in the April 1982 HAWAIIAN SHELL NEWS stating that a fine specimen of Valuta musiaa demarooi Olsson, 1965, a Caribbean species, has been found at Poneloya, West Nicaragua. This was reported by Fathers A1 and Julio Lopez of the University of Central America in Managua. In summary, the number of currently known Indo-Pacif ic gastropods found within the continental shelf of the tropical eastern Pacific is 15, and the circumtropical gastropod species is 6. I have reported an additional opisthobranch to the circum- tropical species for a known total of 12. In addition, I have cited one Caribbean gastropod reportedly taken on the West Nicaraguan mainland.

Box 1390, San Diego, California 92112 COMPENDIUM OF SEASHELLS By R. Tucker Abbott and S. Peter Dance 1982 E.P. Dutton, N.Y., 378 pages, 360 plates + bibliography and index, quarto size Price: $52.00 This finely illustrated work is an excellent identification manual, useful for new or longtime collectors. It is not directed to scientific workers in taxonomy. For this reason it should not be evaluated by standards used for taxonomic studies. The species selected for illustration in this volume are those most likely to be chosen by collectors because of their beauty of color, form^and size. Most of the specimens are arranged in inserts of 12 individual shells to a plate. Molluscan shells which are essentially colored in light or dark warm tones and colors in nature are here placed against suitable light or dark, cool, colored backgrounds. This scheme does achieve maximum clarification of form and color values. There are short notes below each figure giving both common and Latin names, average size, and a few words on habitat. The bibliography is adequate for the purpose of this book, and the short intro- ductory notes on classification, storage, and care of shells is similar to most such essays directed to aesthetically oriented collectors. The short errata slip includes most of the more obvious errors. On the debit side, generic placement of species is inconsistent^ following, at times, some serious research work and at others a broad, simplistic classification. A problem of such books as this is the misleading typological species concepts given by the illustration of the "gem quality" specimens selected. These specimens, usually selected for size, beauty of form, and color may be very different from the average specimen in any population. In nature, species often consist of highly variable individuals. One illustrated figure, whether of a type or a specimen se- lected at random, cannot reveal the extent of the diversification of the species. This diversity, which is a result of genetics, ecology and geography, is the bane of a systematist ' s efforts to understand a species. It also provides new aspects of nature for aesthetic appreciation. This book has much value for quick, easy identification of the of species illustrated, and especially in its use of full color. extensive number SAN DIEGO SMELL CLUB % C. HERTZ 3883 m.

HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 SEA SHELLS OF SOUTHERN AFRICA By Richard Kllburn & Elizabeth Rippey 1982 Macmillan South Africa Ltd. ISBN 0 86954 094 7 249 pages, 46 color plates, 230 text drawings Price: $49.95 This book is special — a "quality product" which will captivate the collector as well as provide valuable information for the student and research worker. This ambitious work treats the littoral zone (beach to 4 m. ) from the northern border of Namibia (Kunene R. ) to the northern border of Zululand, a most diverse area called southern Africa. Of the less than 1500 littoral molluscan species inhabiting this area (author's estimate), close to 600 are illustrated and discussed. Unfortunately, from the point of view of this reviewer, the minute species were omitted as well as "mostly scarce, obscure... or shell-less" species while "a selection of deep-water molluscs that are of particular interest to collectors..." is included. The illustrations by Elizabeth Rippey are an artistic treasure and in many ways are superior to photographs as tools of identification. For each species included there is at least one painting, usually two or more, which highlight the distinctive qualities of the species. For the gastropods there is usually a dorsal and ventral view, and color and/or sculptural variations illustrated. For the bivalves, too, color forms are shown, often with interior or hinge views. In addition, most bi- valves are reillustrated in the text with excellent black and white camera-lucida type drawings. Thirteen chiton species are included and shown both in color and in detail drawings. The text is arranged in taxonomic order (gastropods first here) with an intro- duction to each order preceding the discussion of the families within the group. The species are arranged by genera and a brief description and geographical range is given for each species followed by a section called "Notes " which varies from a sentence or two to several paragraphs. For me, this section, along with the family discussion, are the goodies in the toy box — spawhlhg notes (with drawings of egg capsules), habitat and rarity information, comparisons with closely related species, and Indications of taxonomic problems. Nomenclatural and taxonomic matters which require further elaboration appear in ' the Appendix I, Taxonomic Notes. For example. Dr. Kilburn suggests changes in some generic allocations and proposes a theory of hybridization between some species of Cypraeidae. It is not the purpose of this review to attempt to evaluate the merits of these and other theories presented. A chapter on the southern African region explains its marine provinces, ocean currents and their effects on the molluscan fauna. The four provinces are individ- ually analyzed and a full page color map facilitates understanding. A map on the inside cover details the coastline with its cities, rivers, and bays. Other sections include the almost obligatory What is a mollusc? and How to build .• a shell collection. Even here, Richard Kilburn has inserted information seldom seen Vol. XV(3) 1983 THE FESTIVUS 32 in popular books. ^ I applaud his Appendix II titled "Scientific names and the beginner" in which he explains the scientific system and advocates the use of scientific rather than common names, recognizing "that most [common names] that appear in popular books have been invented by the author!" The enjoyable chapter on pioneer shell collectors in southern Africa traces the expeditions and collectors from the 1600's and affords the reader glimpses of the early days in the area. In conclusion, this reviewer would have preferred more complete coverage of the littoral molluscan groups treated. As examples, only seven terebrid species are included out of that large group and the Pyramidellidae is scarcely touched with only five species shown. Also, as noted before, the book includes only a smattering of raicro-mollusks. This does not diminish the value of this work as a library addition whether or not the reader has collected or will ever collect shells from southern Africa. FROM THE MIiMUTES BY JOHN SAGE The February meeting was called to order at 7:45 P.M. New members and guests were v7elcomed. Vice President Ron McPeak introduced the evening's speaker. Dr. Richard Brusca, whose expertise on the natural history of Baja California was demonstrated with an outstanding slide and narrative presentation. After the refreshment break, a motion was carried to approve the January minutes. It was announced that Abbott and Dance's COMPENDIUM OF SEASHELLS is available at a reduced rate of $39.00 while supplies last and later at that price if ordered in lots of ten. The members voted to hold the iChristmas party at the Naval Station Officers' Club again this year. Peg Mulliner, Carole Hertz and Jayne Schmaltz volunteered for the April Potluck/ Auction telephone committee. Members were reminded and urged to bring their donations for this event to the March meeting or to contact a board member to arrange for pickup of their donations. Carole Hertz won the shell drawing and the meeting adjourned at 9:05 P.M. THE ANNUAL AUCTION/POTLUCK The Club's Annual Auction/Potluck, our most exciting social event (and ONLY fundraiser) will once again be held at the home of Marge and Hugh Bradner on April 30, 1983. (Map and details will be in the April issue) . The proceeds from the auction provide the major portion of the Club's operating funds: The Festivus depends on its success for its budget and it supports our dona- tions to scientific organizations and purchases for the Club library. We urge our members and friends, local and out-of-town, to donate quality shells (with as much data as possible) to the Auction. (Receipts will be provided, on request). Bring your shell donations to the March meeting or arrange with a Board member for its pickup. Donations may also be sent to the Club address. And come to the Auction, members and friends. It's fun!!

MYERS Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 ABSTRACT: The radula of Pteropurpura bequaerti (Clench & Perez Farfante, 1945) is figured and an amended description of the species is given. P. bequaerti is recognized as a cognate of the western North American species P. vokesae Emerson, 1964. The donation of a mature specimen of Pteropurpura bequaerti (Figure 1) to the San Diego Natural History Museum by Lyle Campbell of the University of South Carolina at Spartanburg, occasioned an examination of this species. P. bequaerti was described from a specimen dredged in 80 fathoms (146.4 m) off Delray, Palm Beach Co., Florida. Fig. 1. Dorsal and ventral views of P. bequaerti. SDNHM 81625. Vol. XV(3) 1983 THE FESTIVUS 34 The geographical distribution was given as extending from North Carolina south to the Florida Keys. The holotype, deposited in the Florida State Museum, is 25 mm in length with a broken canal and rounded vari- ces in profile (Figure 2). A study of the material at hand shows that the description of P. bequaerti may be amended as follows: Shell attaining 50 mm in length; protoconch of Ih smooth whorls (Figure 3) followed by 6 to 8 post- nuclear whorls; multiple varices appearing on first postnuclear whorl; shell becoming trivaricate on the fifth or sixth postnuclear whorl with a single strong node or several small wrinkles occurring between the varices; varices moderately recurved, becoming pointed along the margin; suture impressed. Aperture oval, slightly notched at opening of siphonal canal; inner and outer lips erect; outer lip sometimes with 4 to 5 denticles within the aperture. Siphonal canal moderately broad above, becoming tubelike distally, recurved and bent to right; two previous canals occurring on siphonal fasciole. Spiral sculpture of 5 primary cords including shoulder cord with small threadlike cords in interspaces. Entire shell often weakly scabrous. Operculum (Figure 4) is Ocenebrlnae. Color ranges from pure white to pale yellow ochre. The Ocenebrinae radula (Figure 5) is approxi- mately 13 mm in length and contains 350 rows of teeth. Notable features of the radula are the double end points on the rectangular base, the intermediate cusps appended to the laterals, and the presence of 2 to 4 denticles between each lateral cusp and endpoint.

Clench and Perez Farfante compared P. bequaerti to P. macropterus (Deshayes, 1839), but P. maaropterus is a distinctly different species with lobed varices. Emerson (1964a) clarified the taxonomic status of P. macropterus. A comparison of a number of specimens of P. bequaerti [Recent from North Carolina to the Dry Tortugas, Florida, (Figure 6) and Pleistocene fossils from Louisiana (15,000 YBP) (Figure 7)] with P. vok.esae Emerson, 1964 reveals few qualitative differences and demonstrates the close similarity in shell morphology of these two Fig. 6. Dorsal and ventral views of P. bequaerti, showing well developed recurved and pointed varices. AMNH 167186. cognate species. In the numerous examples of P. vokesae examined , denticles are lacking within the outer lip. Quantitative differences consist of the larger size of P. vokesae, its much more scabrous surface, and more strongly recurved flange. The flange terminates in strongly recurved longer points which are extensions of the spiral cords (Figure 8) . The known geographic distribution of P. vokesae is from Santa Rosa Island, California to San Bartolome Bay, Baja California, Mexico (McLean, 1978). The holotype (Figure 9) is in the United States National Museum y/160500 as Murex (Atipurpura) rhyssus Dali, 1919. P. vokesae Emerson, 1964 is a replacement name for M, rhyssus Dali, 1919, preoccupied by Murex (Pteronotus) rhysus Tate, 1888, a fossil from the Tertiary of Australia. Details of the checkered nomenclatural history of P. vokesae can be found in Emerson (1964b) . Voi XV(3) 1983 THE FESTIVUS 36. Fig. 7. Dorsal and ventral view of P. hequaerti.

Box 1390, San Diego, California 92112 In a recent issue of The Festivus [13(6) :73], I had occasion to comment on the poorly known species, Favartia sykesi- (Preston, 1904). A figure of F. sykesi in Ruth Fair’s THE MUREX BOOK published in 1976, was cited as the holotype. In order to further study this species and to illustrate it well, I borrowed a specimen from the Los Angeles County Museum of Natural History which was said to be a paratype of this species. This specimen was figured in The Festivus (ibid). A recent communication from Ms. Kathie Way of the British Museum of Natural History Mollusca Section, makes it apparent that a holotype was never chosen and that any other specimens of this species in the type lot remain as "probable syntypes." Ms. Way's letter, reproduced below, serves best to explain this situation. T4l*fTamt. Southkent, London TtlrpMvm: ot‘S^9 ^3*i BRITISH MUSEUM (NATURAL HISTORY) Cromwell Rood London. SW7 SBD Dr A.D'Attilio, Dept. Marine Invertebrates, Natural History Museum, Balboa Park, Sfui Diego, California 92112, USA. November 26th 1982 Dear Dr D'Attillo, Whilst filing the reply to my recent letter to you, I came across a note concerning something about which I meant to write to you some time ago. In The Festivus XIIl(6) :73,' 981 ,pl.1 , you figure a "paratype" of Favartia sykesi Preston. I feel I should point out that Preston did not designate a holotype at any point in his description, the B.M.(H.H.) specimen figured by Fair as the holotype is, in fact, the figured syntype (reg.no. 1 905.2,8.7)^ We also have two further probable sjmtypes ( reg.no.1 904.5.1 1 .1 1 -1 2) ; I am unable to prove that Preston had these specimens to hand when he desccibed M. sykesi . although they were presented to us by him in 1904. I was moat interested to learn of the presence of Preston syntypes in the Los Angeles County Museum; do you know if any catalogue of such material is available? Yours sincerely Ms Kathie Way Molluscs Section ’♦’dorsal & ventral views enclosed. Vol. XV(4) 1983 THE FESTIVUS 41 Preston described F. sykesi in the Journal of Malacology and figured the species. The specimen illustrated below in Figures 1 and 2 was graciously provided by Ms. Way. It is the same specimen figured by Preston and appears, also, to be the specimen figured by fair. Figure 1.

By 7:30, with gear and peso in hand, we were on our way. The first day of traveling was uneventful. If pushed, the trip to Bahia de Los Angeles takes 10 to 11 hours. We decided to take our time and make it a Ih day trek. The lead vehicle was manned by Dave Mulliner with Peggy as co-pilot. Behind him cruised another camper piloted by Barney Barnhart and Carol Elliott. Our Jeep Cherokee with Pat Sage, her son Mark and I took up the rear. After a stop to secure Dave's boat after a metal strut broke, we continued on until we arrived outside Catavina into what can only be described as a desert wonderland. Giant granite boulders piled on top of one another resembled majestic castles. Plant life abounded from small shrubs to the spidery Cholla and the mighty Cardon whose arms soared sky- ward to a height of 30 to 40 feet. After setting up camp for the night, time was spent exploring this beautiful area, rock climbing, and identifying flora. The sun rose brightly over the mountains the next morning and we were on the road by 7:00 A.M. We stopped briefly at the nearest gas station and toured the nearby El Presidente Hotel. It is truly a gorgeous place with tiled walkways, gardens with bubbling fountains and flowering plants adorning the patios. Several hours later, after stopping at the side of the road to gather firewood for the evening campfire, we drove to the top of the last ridge and Bahia de Los Angeles spread out before us. We marveled at the sight. Here was a deep blue bay extending out as far as the eyes can see. Islands of various sizes dot the waters of the bay. Cameras snapped to capture the scene. Then everyone scrambled back into their campers to get down to sea-level. We had arrived at the campsite by noon and set about organizing our camp. Soon it was slack tide and the water line only about 20 feet away. Mark and I decided to check out the immediate area for shell life. We slipped into our snorkeling gear and went in to a nice warm bay. Since the current was strong, we were restricted to a protected area with a sandy bottom and large stationary and turnable rocks. We had to swim out a little way to leave the cobbles along the shoreline. The molluscs here were very limited. One of the more interesting was the bivalve Chione tumens (Verrill, 1870). Peggy recognized it Immediately, not by the name but by the catalog number in Keen’s SEA SHELLS OF TROPICAL WEST AMERICA,— No. 444. For the rest of the trip this shell would be affectionately known as four-four-four. The only other shell we found there was Thais speaiosa (Valenciennes, 1832). After dinner, we christened the camp with the first campfire of the trip. To- gether we sat toasting marshmallows and sipping Kahlua while a gentle breeze drifted in from the desert. Monday, November 1 found everyone getting ready for the first dive of the trip. One of the Zodiacs which Dave had brought had to be inflated after Mark and I found the aluminum boat extremely unstable. We had taken it for a trial spin and almost wound up in the bay with the boat on top of us. The gear was loaded into the two boats. Dave, Carol. and Barney went into one, while Mark and I climbed into the Zodiac Dave sped out toward a reef situated between Smith and Guano Islands. Mark started the Sage's new outboard motor. About halfway between shore and the reef, it died. Mark tugged at it for about twenty minutes before deciding it was time to start rowing. About this time Dave headed back to see what the trouble was and towed us back to shore where we changed motors and once again headed out to the reef. This time we made it. Vol. XV(4) 1983 THE FESTIVUS 43 We anchored over a section of reef which was made up of vertical cliffs and branching canyons adorned with corals and sea fans. Fish swam in all directions and were curious about us. I saw a variety of angel fish and butterfly fish as well as the common puffer fish. After a few minutes I*d collected two Jenner'ia 'pustulata (Lightfoot, 1786), a variety of sulfur-colored sea fans and several species of nudibranchs for Dave to photograph. It was on this dive that we collected what we thought to be Conus emevsoni Hanna, 1963. We resisted any alternate identification for the shell such as the columbellid Parametaria maorostoma (Reeve, 1858) suggested by Peggy. We knew that the possibility of our shell being a cone and a range ex- tension was remote but we'd hoped. However, Peggy was right, after all. The rest of the day was spent admiring our catch, fishing from shore and chasing seagulls and pelicans away from the tackle box. After dinner we nestled down by the campfire with good friends, toasted marshmallows, and dixie cups of Kahlua. That night the wind blew strong and steadily. It would be our constant companion during the rest of our evenings and many of our days. Near gale force winds greeted us on the morning of November 3rd, converting the entire bay into a storm-tossed fury. The pop-up trailer that housed Pat, Mark and me shook and filled with wind like a parachute. It was decided thakPat and Mark would bunk with Dave and Peggy while I opted to make a windbreak of stones and camp out. But this would not be necessary. We were to meet the Bradners and Jayne Schmaltz that afternoon. However, they'd found our camp themselves and also discovered an abandoned fish factory — perfect shelter for protection against the elements. There was plenty of room for those of us who were going to sleep inside. Outside, the pop- up trailer was again erected on the leeward side of the building. Pat set up house- keeping inside the pop-up again. The evening was spent around a glowing campfire with marshmallows, Kahlua and singing to Mark's talented guitar strumming and picking. The wind had finally died down to a refreshing breeze. The next day the bay was still rough but some of us finally had the opportunity to go dredging for the deeper water shells. Finally, on the 5th of November, after four days of gale-force winds, we were able to go diving. We all piled into the aluminum and Zodiac boats and headed out to Calaveras Island, located just south of the reef we'd dived previously. Scores of sea lions were basking on the rocks with several large bulls majestically poised there. The water, after the storm, was slightly cooler but crystal clear. The bottom was a combination of sand and rocky rubble with algae and corals. Among our diving companions were the sea lions who were delightfully curious about us. Our second dive of the day was at the northern face of Smith Island, the largest island in the bay. Here, protected from the afternoon wind, the water was calm and the terrain totally different. Boulders were strewn over the bottom and piled on top of one another. Some were small, others as big as a living room. On this dive Mark found a beautiful Conus pr'tnoe'ps Linne, 1758. That night we had a fantastic fish dinner with what we had caught the previous day. After the familiar campfire, drowsiness came early. It had been a big day. The next day, still tired, we spent sunbathing, dredging, cleaning shells, being chased along the beach by a bull sea lion, and digging clams in the estuary for the evening meal. We had a gorgeous dive the next day. It was Jaynes first look at the reef and a nice revisit for the rest of us. This area was the only one in which we'd found Jenneria pustulata. We looked, too, for additional Cypraea annettae Dali, 19Q9 for Brad's radula studies. We managed to collect several of both species. That afternoon the wind picked up again and the night was a restless one as gusts blew from the south and into the "factory." The next morning was just as windy and it began to rain. Brad, Marge and Jayne decided to leave and the rest of us made preparations to leave the next day. Pat and Mark decideid to spend the last night in town and celebrate her birthday. The Mulliners graciously invited me to spend the last night with them in their camper. The next morning, just before leaving, I found two stranded sea snakes along the 44 THE FESTIVUS Vol. XV(4) 1983 pebbly shore. I put the snakes into a plastic container for transport to their final destination, the San Diego Natural History Museum. Finally, with everything stowed away, we said a sad goodbye to Bahik de Los Angeles. The trip had been an exciting and memorable one.

FROM THE MINUTES BY JOHN SAGE The March 17 meeting was called to order at 7:45 P.M. New members and guests were welcomed and Vice President Ron McPeak introduced the evening's speaker, Mr. Lester Knapp, who gave a slide presentation on "Travel in Tahiti". Of special interest were the beautiful shots of Tetiaroa and the conservation efforts of Mr. Marlon Brando, owner and "caretaker" of the island. Ron McPeak gave a mini-slide presentation of a special family member's yearning for the ocean to calm so there could be diving as usual. Following the refreshment break, the February minutes were approved. Members were reminded of the need for donations for the Auction/Potluck and a sign-up sheet for potluck contributions was circulated. Ron announced that the speaker for the May meeting would be Mr. Stan Strauss whose topic will be "Underwater Photography of the Red Sea and Truk Lagoon". Treasurer Wally Robertson reminded members that 1983 dues were due. Botanical Garden Foundation Representative, Marty Schuler was sent information on the upcoming annual plant sale to be held 28 and 29 May 1983. Donations will be accepted in Room 104, Casa del Prado until 6:00 P.M. on 27 May 1983. Contact Marty Schuler for further information. Members were urged to donate to this sale. Mike Anderson won the evening's door prize and the meeting was adjourned at 9:00 P.M. Vol. XV(4) 1983 THE FESTIVUS 45 FOLLOW-UP OH "COLLECTING IN FIAZATLAN" BY JULES HERTZ and CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In the February 1983 issue of THE FESTIVUS, the authors listed and pictured (Vol. XV(2):20, figs. 2,3) a species as unknown. We have recently received corres- pondence from Bertram C. Draper which indicates that this species is most likely Rissoella tumens (Carpenter, 1857). Originally, it was thought by the authors and Bert Draper that the species might be Rissoetla exootpa Bartsch, 1920. However, our specimen has an extra whorl and is considerably larger than the largest R. exaotpa which are approximately 3 mm in length. Through the kindness of Bert Draper we have been able to track down the pertinent literature on R. timens . Carpenter's original description given below lists the habitat as Mazatlan. Brann (1966, pi. 39) illustrated one specimen from Carpenter's Tablet 1719 (shown here as Figure 1). Carpenter's camera lucida figure is of a juvenile specimen. MAZATLAN UNIVALVES 363 421.

Bartsch (1920) also figured the type, but again this is not too helpful in identifying an adult specimen. Baker, Hanna, & Strong (1930) figured an adult specimen (see Figure 2) of 4.0 mm in length. This was a plesiotype. No. 4610 (CAS) from Cape San Lucas, Baja California, Mexico. They stated that an adult specimen has six whorls and measures; length 4.3 mm, diameter 2.9 mm. The specimen listed as unknown was remeasured and it was found that the originally reported measurements of 6.0 mm by 3.8 mm were in error. The corrected values are approximately 5.2 mm by 3.1 mm.

SHELL hORPHOLOGY. AND RADULA BY ANTHONY D'ATTILIO Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 A number of specimens of Homalooantha seaunda (Lamarck, 1822) (Figure 1), obtained by fishermen from the extreme southern tip of India were recently brought to my attention through the cour- tesy of Mr. Loyal J. Bibbey of Imperial Beach, California. These 14 or 15 specimens which compare favorably in shell characters with specimens of this species from western Australia suggest an Indian Ocean distribution. A number of specimens from Port Hedland and Broome, West Australia, were sent to me by Mrs. E.A. Seymour and other col- lectors from that area some years ago. According to information supplied by Mrs. Seymour, the specimens occurred intertidally at Port Hedland. All specimens, including living ones at this locality, were much encrusted with various calcareous marine growths which practically obscured the specimens except when the mollusks were moving. When cleaned of the incrustations, the color was found to be mostly shades of light to dark brown with occasional specimens entirely white. The specimens in the lot from India were mainly white, with some showing pale rust to light brown ^ mostly on the varices. A single specimen with immature outer lip (SDNHM 24134) has the locality noted as Ceylon. It is colored entirely medium brown. In MUREX SHELLS OF THE WORLD, Radwin & D'Attilio (1976, pi. 8, fig. 5), a specimen illustrated as H. seaunda which was said to be from New Caledonia is probably referable to the taxon E. lamberti (Poirier, 1883). See Figure 2. It appears that H. lambei't'L is a valid related species with a distribution in the south Pacific in the area of New Caledonia. Based on the specimens from India, an amended description of Homalocantha seaunda follows. Homaloaantha seaunda (Lamarck, 1822) (Figures 3a, 3b) Specimens are broad, low spired, with a protoconch of rounded smooth whorls (Figure 4). The teleoconch consists of 4 whorls; the suture is deeply impressed within an excavated area between the shoulder and the whorl above Fig. 1. H. seaunda, holotype, from Fair (1976) 255a Fig. 2.

Dorsal view of same specimen shown in Fig. 3a. Photos by David K. Mulliner and is interrupted by the varical flange crossing the shoulder. There are 5 varices per whorl including the apertural varix. Varical sculpture consists of one primary spine above the shoulder, 4 on the body whorl, and 2 on the canal. The primary spines are mostly terminally bifid; the margins of the spines fold over the ventral side and are firmly appressed with an open area between; intercalary shorter spines are present between the major ones; an additional pair of intercalary spines occurs between the body spines and those on the canal. The leading side of the varices has a draped-like lamellate surface; the receding or dorsal side and the intervarical areas are obsoletely scabrous. The aperture is ovate, nearly entire except at the entrance to the canal; the entire apertural margin is mostly erect. The canal is closed mostly centrally, is broad above, tapering tube-like, and terminally recurved. The siphonal fascicle retains the distal portions of 3 previous canals. Fig. 4. Protoconch of E. seounda Specimen from South India, at 2.5x 50 THE FESTIVUS Vol. XV(5) 1983 The radula shown here in Figure 5 is from a specimen from Broome, West Australia. To my knowledge, the radula of this species has not been previously illustrated. The thin, horny operculum (Figures 6a, 6b) displays a strong resemblance to that of Ocenebrinae species. Fig. 5. Radula of H. secunda Fig. 6a. Exterior of operculum of H. secunda Fig. 6b. Interior of same operculum shown in Fig. 6a Remarks on the systematic position of this genus within the Muricidae have been made by authors relative to its subfamilial placement. The closed canal and ocenebrinid operculum suggest the subfamily Ocenebrinae. The character of the rachidian plates of the radula demonstrates, among all species of this genus examined, a consistency in the possession of blunt, short c^ntrsvl and lateral cusps with the intermediate cusps poorly developed and appearing as appendages of the two lateral cusps. This radular configuration is not typical Muricinae nor is it Ocenebrinae. Until more is known, probably about soft part anatomy, the placement of this genus in the family Muricidae remains ambivalent. My appreciation to Mr. David K. Mulliner for the photographs of E. secunda. Literature Cited FAIR, RUTH H. 1976.

Vol. XV(5) 1983 THE FESTIVUS 51 ROUGH SEAS AND WAREl WATER AFFECT SOUTHERN CALIFORNIA KELP BEDS BY RON H. McPEAK Kslco, Division of Merck, Inc., 2145 East Belt Street San Diego, California 92113 Beds of giant kelp (Maaroaystis) are very important ecologically be- cause they provide habitat, substrate, and food for a variety of animals. The ecological importance of Maoroeysti-s was noted by Charles Darwin in 1834 when he wrote, "A great volume might be written, describing the in- habitants of one of these beds of sea- weed...! can only compare these great aquatic f orests . . . with the terrestrial ones in the intertropical regions, yet, if in any country a forest was des- troyed, I do not believe nearly so many species of animals would perish as would here, from the destruction of the kelp.” Maorocystis grows in beds in the nearshore waters of Southern California at depths ranging from 20 to 120 feet. The plants attach to the bottom by a holdfast, a complex of root-like structures which simply anchor the plant to the bottom. See Figure 1. Fronds (stems) originate at the base of the plant near the hold- fast and eventually grow to the sur- face to produce a "canopy.” See Figure 2. Gas-filled bladders float the fronds away from the bottom. Giant kelp plants are perennial, living for several years, while individual fronds live for only six months. Throughout the natural cycle of a kelp plant, mature fronds con- tinually develop, then die and break away, giving way to new fronds growing up from the bottom. Fig. 1. Holdfast of a Maorocystis plant, from Divers Log, Jan-Mar. 1983 Photo: Ron H. McPeak THE FESTIVUS Vol. XV(5) 1983 32 SURFACE CANOPY APICAL BLADE The frequency and intensity of storms can change the length of time a kelp forest persists. Severe storms quickly uproot plants or snap plants at the base causing the demise of entire MaoToeystis populations. This was the case this year. Huge swells pounded the California coastline from mid-January through early March 1983, destroying significant areas of kelp. Many thousands of plants were uprooted and cast on California beaches. Animals living in the intricate holdfast {Hiatelle avatiaa) or attached to fronds ( Norrisia norrisi^ Mitrella oarinataj Lacuna unifasciata) were also deposited on beaches. The full impact of recent storms on a Macrocystis forest was noted in a survey on April 28, 1983 by Kelco biologists off South Point Loma. A survey of the 40 foot station revealed almost no living Maorocystis in an area which supported a dense population of giant kelp in 1982. The plants had been uprooted or snapped at the base. (Under optimum conditions it will take a minimum of one year before kelp again becomes established and produces canopy) . Giant kelp beds off Southern California have been further affected by abnormally warm water, a warming condition sometimes referred to as an "El Nino." The name, in reference to the Christ Child, was first given to warm ocean conditions off Peru which developed during a Christmas season. When an "El Nino" occurs, there is a shift in the winds and a reduction in the flow of currents off Peru. The last major "El Nino" occurred along the coast of California during 1957 through 1959. Maorocystis canopies diminished significantly and many warm water or tropical species were observed along the California coast. Pelagic red crabs, Pteunonaodes ptanLpeSj were abundant as well as several species of tropical fishes. Sea surface temperatures in Southern California have been above normal since July 1982 and have increased dramatically during early 1983. They have averaged more than 3.5°F above normal from January through March. As recently as late April 1983, Kelco biologists observed triggerfish and pelagic red crabs off Point Loma. Above normal temperatures indicate low levels of nutrients and generally result in poor kelp growth. During the warm period since July 1982, fronds have grown slowly and produced little kelp canopy in Southern California. Grazing by sea urchins (Strongylocentrotus purpuratus^ S. franoisoanuSj and Lytechinus anamesus) is further diminishing the kelp resources already depleted by winter storms and the "El NinoV When kelp is abundant, urchins feed on drift Maorooystis and move very little. When the food supply is insufficient, the urchins move_ considerable distances and consume attached vegetation. See Figure 3. Researchers in Southern California kelp forests have identified more than 114 species of motile invertebrates living on fronds of MacvocystLs (Coyer, 1979), 175 species of invertebrates living in Macrooystis holdfasts (Ghelardi, 1971), HOLDFAST Fig. 2.

MYERS Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 SEASHELLS OF OMAN By Donald and Eloise Bosch, 1982 Longman Group Ltd, London and New York. 206 pp. 373 Photographs ISBN 0-582-78309-7 Price: $35.00. 1 The Sultanate of Oman, the area covered in this volume, comprises, according to the authors, a coastline of more than 1,000 miles. It is located on the west side of the Gulf of Oman which is an extension of the Arabian Sea. This husband and wife team spent 25 years collecting along this coast and their observations on the life history of the 373 species of mollusks treated in this illustrated guide add considerably to the book's value. During their stay in Oman, they discovered four species of mollusks new to science. These have been described elsewhere: Aoteon etoiseae Abbott, 1973; Cymatium (Ranulavia) hoschi Abbott & Lewis, 1970; Volvarina pergrandis Clover, 1974; and Conus bosohi Clover, 1972. The book is essentially a field guide, not a scientific treatise or taxonomic work and the nomenclature is not consistent. It contains the usual Introduction and chapters on classification, shell structure and growth, reproduction, cleaning shells, etc. There is a glossary, a good index, and a bibliography to general books on mollusks. It is printed on glossy paper, is well bound, and has a sturdy hardcover. The color photographs are excellent and show an artistic arrangement of the shells by the photographer rather than the usual placement with the center line of the shell vertical on the page. This positioning of the specimens often is advantageous in pointing out a particular shell characteristic. A few shells do appear fore- shortened and a little difficult to orient, while Stvomhus deoovus persi-ous appears sinistral. The format and artistic quality of the book are exceptional. Its usefulness as a reference for collectors in that area is enhanced by the locality and habitat data contained for each species. •< I i I f I ( k SEASHELLS OF THE ARABIAN GULF 'j By Kathleen Smythe, 1982 j George Allen & Unwin Ltd., London. 123 pp., 20 pis. ^ ISBN 0-04-594001-0 j Price: $25.00. | The Arabian Gulf, also known as the Persian Gulf, or just The Gulf, is an ex- f tension of the Gulf of Oman beyond the Strait of Hormuz, northwest to Kuwait. This | is the area covered by this pocket-sized publication. The book is not a companion » to the above reviewed work, SEASHELLS OF OMAN, but belongs to a continuing series f on the NATURAL HISTORY OF THE ARABIAN GULF. Four previous volumes have already been j published treating the mammals, inshore fishes, birds and wild flowers. I found the volume disappointing. The eight color plates and 12 black and white plates are of average to poor quality and many of the species listed are not illus- | trated at all. Although essentially a field guide, no localities are given for most i of the more than 300 species treated. One cannot assume they are all found through- Vol. XV(5) 1983 THE FESTIVUS 55 out the Gulf since the author clearly states in her Introduction that the fauna differs from locality to locality. The book is printed on glarefree paper and has a semi-hard cover. The Introduction contains some useful information regarding the history of collecting in the Gulf and information on the Gulf itself. It also contains the usual prelude to the Phylum Mollusca, brief instructions on collecting, cleaning, recording and storage of shells, etc. There is a short glossary, and index that lists only binomens, and a bibliography to general books on mollusks. It is my opinion that this volume has limited use as a field guide to collectors or as an identification tool, although it is the only recent general work for this area.

These distinctions can be subjective, and have resulted in many disagreements between "splitters” and "lumpers." In the genus Cypraea, for example, the Schilders (1938-39) divide the Cypraeideae into 4 subfamilies, 8 tribes, and 24 genera. Other taxonomists have split genera and species even further than the Schilders. Wagner and Abbott (1977), who are among the con- servative "lumpers" name 66 subgenera while recognizing 185 valid cowrie species in the approximately 1,100 names that they list. Kay (1960) attempted to reduce the taxonomic complexity of the genus Cypraea by grouping the cowries according to anatomical features, especially the radula. She found that the 51 species studied could be separated into 4 radula types, and thus showed convincingly that none of the existing systems of classification could be completely right. Although Kay now feels that the classes should be expanded to more than double the original 4 (Kay, pers. comm.), her 1960 paper is still the definitive work. The purposes of the present paper are to extend Kay's 1960 work by examining a large number of Cypraea species under the high resolution of the scanning electron microscope to determine whether her 4 radula types are distinct and all-inclusive, and to consider whether they form a possible basis for a new generic classification. The 4 radula types are shown in Figure 1 and Table I adapted from the sketches % — C. caput serpentis R2 — C. tessellata Figure 1.

Radula types adapted from Kay (1960). Uniformity within a type A great similarity among species in a type can be illustrated by C. sohi-lderorum (Figure 2), C. lynx (Figure 6) and C. vitellus (Figure 7) all of type 4. The correspondence between radulae in specimens from different collecting areas is often striking, as in C. lynx from Fanning Island (Figure 6) and from Tahiti (Figure 8), 1600 miles apart. In contrast, specimens of identical species collected in a single area can sometimes show significant differences. For example, two specimens of C. semiplota showed central teeth with 3 denticles (Figure 9) while one other specimen from the same collecting area at Fort Kamehameha, Oahu, H.I., had 5 denticles (Figure 10) . Radular teeth of a specimen of C. annae collected at Fort Kamehameha were indistinguishable from those of Figure 10) , lending support to the argument that C. annae and C. semiplota belong to the same species. In contrast, Bradner (1979) noted that the radulae of C. isabella and C. isabellconexioana show such consistent differences that the assignment to different species appears justifiable in spite of the very similar appearance of their shells. In some cases the species can be de- termined from a single specimen. An example was the radula (Figure 11) from a specimen whose shell had been "deflnitly identified" as a mature C. annulus from Tahiti. The radula is of the type of C. obvelata and not C. annulus (Figure 12). Further comparisons will be of interest in specimens from the Cook Islands, Jarvis Island and Fanning Island where the distribution of the two species are reported to overlap . 59 THE FESTIVUS Vol. XV(6) 1983 Fig. 2.

C. semiplota Vol. XV(6) THE FESTIVUS 62 Intergradations and exclusions Not all radulae can easily fit into Kay's 4 classes. An example is C. stolida ftuotuans (Figure 13) which has central and lateral teeth with some characteristics of types 3 and 4, but has distinctly different shaped marginal and submarginal teeth whose nearest counterpart is C, staphylaea type 1. The radula of C. asettus (Figure 14) is significantly different from all 4 classes. A cypraea specimen is occasionally found with an aberrant radula that is grossly different from the norm. An extreme example is shown in Figure 15, from a normal C. onyx melanesia specimen. This radula has two well developed extra denticles on each marginal tooth. These sturdy m.arglnals could be of significant value to an animal that is carnivorous, or that feeds on especially tough plants. Conclusion SEM studies of radulae can make valuable contributions to quantifying differences between Cypraea genera, and frequently can be an aid in resolving arguments about species differences. However intra-population differences can be large enough to Fig. 13. Cypraea stolida fluotuans (Eredale, 1935) Figure 14. Cypraea aseltus Linne, 1758 63 THE FESTIVUS Vol. XV(6) 1983 / prevent definite species identification from a single specimen. Conversely, however, if two radulae are indistin- guishable under SEM there is good cause to believe that they are of the same species . Although Kay's classification was an important step toward simplifying Cypraea taxonomy, she states (pers. comm.) that a better basis for classi- fication appears to reside in modern phylogenetic techniques of cladograms, etc. applied to statistically significant (large) samples. Ultimately, of course, each individual is genetically unique, so the decision must still be sub- jective regarding which genetic characteristics to select for the classification. In reviewing this paper. Professor Kay kindly communicated the text of her introduction to Dr. Burgess' forth- coming book on cowries. In it she dis- cusses pertinent characteristics of ten species complexes or subgenera. In distinguishing them she considers protoconch, shell shape and markings, mantle, foot, and genitalia in addition to optical and SEM appearance of radula. Fig. 15. Cypvaea onyx meZanes'la (Schilder, 193 She does not propose a comprehensive generic classification of the cowries.

HERTZ, JOYCE GEMMELL Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In working on the bivalves from the Gemmell collection from San Felipe, Baja California, Mexico, we checked the synonymy of Maooma (Psammacoma) elytrum Keen, 1958, a replacement name for Tellina elongata Hanley, 1844 [not' Tellina elongata Dillwyn, 1823 ex Solander MS] . In 1958, Keen described M. etytmm, ( holotypej CAS Paleo. Fype Coll. 10503) [now numbered CASIBP 032539] from SSW of Maldonado Pt., Mexico, and figured a hypotype (CAS 10504) [now numbered CASIBP 032540] from Monypenny Pt., Gulf of Fonseca, Nicaragua. See Figure 1. At that time Hanley's type material of Tellina elongata in the British Museum of Natural History (BM(NH)) was not available for loan. Fig. 1. Hypotype of Maooma elytnm We were fortunate enough to borrow the (CASIBP 032540) from Keen (1958, pi. 30) three syntypes of Tellina elongata Hanley from Solene Morris of the Bivalve Section, BM(NH) . These syntypes remain the type material for M. elytmm [ICZN 1961, Art. 72 (d) , p. 75] and we have chosen as lectotype T. elongata (BM(NH) 1874.12.11.354). See Figure 2 of the lectotype and a copy of the front and back of the label accompanying the lectotype specimen. Keen's type of M. elytvim from SSW of Maldonado Point (CASIBP 032539) which appears to match the figure in Keen(1971, fig. 562), and the lectotype of T. elongata (Figure 2) show no morpho- logical differences.

See Figure 5. She stated in her letter accompanying the loan, "...I am sending the specimen most likely represented by Hanley’s figure in the Thes. Conch. . That figure is reduced and misleading if you check the published measurements: (Proc. Zool. Soc., Lond. , (1844) : 144). The specimen is more clearly figured (again) by Sowerby (1867. Conch.

MYERS, JOYCE GEMMELL , CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In our continuing study of the bivalves in the Gemmell collection from San Felipe, we had difficulty in identifying three specimens of a tellin species (Figure 1). At the time, we couldn’t decide if they were TeZZina reoZusa Dali, 1900 or TeZZina brevirostris Deshayes, 1855. According to the distribution data in Keen (1971:221), T. brevirostris is found from El Salvador to Panama and T. reaZusa from San Ignacio Lagoon, Baja California to Panama. The Gemmell specimens were collected in San Felipe from Playa Alicia (approximately five miles south of San Felipe Point) and from the north side of San Felipe Point in May 1968. The valves were still attached. Figure 1.

XV(8) 1983 THE FESTIVUS 82 After looking at comparative material identified as both TelZina reolusa and Teltina brevirostris , we found it neces- sary to study the type material to better understand these two species. The syntypic lot of two specimens of T. brevirostris (BM(NH) 1957.7.15.3-4) was bor- rowed from the British Museum of Natural History [BM(NH)]. Both specimens appear identical with the exception of size. We are figuring the larger of the two and designate it as the lectotype. See Figure 2. The lectotype is 18mm in maximum length, 14mm in height (beak to ventral margin) and 6mm in diameter. Figure 3a is a camera lucida drawing of the interior and exterior of the left valve of the lectotype and Figure 3b is a profile view of this specimen. The paralectotype is 16mm L x 12mm H x 5mm D.

The ma- terial consisted of three vials. Two vials originally numbered USNM 105513 have been separated. One of the vials of three valves is now numbered USNM 66384 and the other (one valve) retains its original type number and says "fig’d typed [sic]'.' The third vial (one valve) is numbered USNM 108544. Dali (1900) did not choose a holotype in the strict sense of the word. Of the five valves in his type material, 2 are left valves, one 20mm L x 15mm H and one 18mm L x 13mm H. He figured a left valve (pi. 3, fig. 2) stating in the explanation of the plates that it was "Lon. 20 mm." This dimension does not conform to that in his original description in which he listed the type as 18mm L x 13mm H. by 6mm D. The vial with the original label stating it was the figured type (USNM 105513) measures 20mm L x 15mm H. No diameter measurement was taken since this would be approximate on one valve. The valve of this figured type has a hole near the beak and is shown here in Figure 4 with a copy of the original label. We have chosen this left valve as the lectotype. Figure 5 is a camera lucida drawing of the interior and exterior of this valve. The lectotype is from San Ignacio Lagoon, Baja California, Mexico. Fig. 4. Lectotype of TeVivna reotusa Dali, 1900.

Olsson (1961) named Merisaa margarita (Figure 6) from Panama. Keen (1971:221) placed this species in the synonymy of TeZZi-no. hvBV'tvoS'tv'ls . However, on the basis of Olsson' s description which states that U. margarita has "fine close-set concentric lamellae^' and the figure of the holotype shown above, we are placing the species in the synonymy of TeZZina reoZusa. Study material in the San Diego Natural History Museum (SDNHM) was examined. It included lots from Puerto Penasco in the northern Gulf of California to Bahxa Concepcion, Espiritu Santo, Mazatlan, Is. Tres Marias, Coastocomate, Tenacatita and Acapulco to La Union, Gulf of Fonseca, El Salvador. An additional 38 lots were borrowed from the Los Angeles County Museum of Natural History (LACM) . They ranged from Bahia Magdalena on the Pacific coast of Baja California to Cabo San Lucas (Muertos Bay) and up the east coast of Baja California (Espiritu Santo, Puerto Escondido, Bahia de Los Angeles, Bahfa Gonzaga, Puertecitos) to Puerto Penasco and south in the Gulf along the Mexican mainland at Guaymas, south to Central and South America (Guatemala, Costa Rica, Panama, Peru and the Galapagos). The lots were studied for sculptural differences and their geographic distri- bution. Our study of this comparative material and the types of both species revealed no differences interiorly between the two species. See Figures 3 and 5. The exterior differences were in the spacing between the concentric striae and in the degree of posterior flexure. In studying a large number of specimens, we noted that they intergraded between the extremes called T. reoZusa and T. brevirostris . Additionally, in lots where there was only a right or left valve, identification was made more difficult because the right and left valves differ in convexity and degree of flexure. After examining the study material and the types we still questioned if the differences in the spacing of the concentric striae and the degree of posterior flexure were enough to consider them two species. We had SEM's made to help clarify morpho- logical details. Figures 7 and 8 (at 13x) show the posterior area of the left valves of two specimens, one identified as T. reoZusa (SDNHM 22203) and the other as 85 THE FESTIVUS Vol. XV (8) 1983 T. brevirostris (SDNHM 22205). Figures 9 and 10 (at 52x) show the concentric sculp- ture of these two specimens just anterior to the flexure. Figures 11 and 12 (at 60x) show the concentric sculpture of these two specimens on the center of the valves. Fig. 7. SEM at 13x of posterior area of left valve of T. yyeoZusa, SDNHM 22203 Fig. 8.

SEM at 60x showing concentric sculpture in center of valve of T. breviTOstvis SDNHM 22205 Note the depressed area just in front of the flexure which ends in an inden- tation at the ventral margin for T. hvev'lvostvi.s (Figure 8) . Also the concentric ribs form an S-shape in this depression and the flexure is pronounced. T. veolusa (Figure 7) has no indentation at the ventral margin, the concentric ribs do not change shape, and the flexure is minimal. The concentric ribs of T. veolusa (Figure 11) are nearly twice as numerous as in T. hveui-vostvis (Figure 12) and there is a slight indication of radial lines between the concentrics of T, veolusa which is absent in T. bvevivostvis . For the present, we consider that there are two species that can be separated on the basis of concentric sculpture and the degree of flexure. Using these criteria for identification, we noted specimens of T. veolusa from the outer coast of Baja California at Magdalena Bay (one lot) and from San Felipe at the head of the Gulf of California (Gemmell specimens) sporadically through the Gulf and south to Guatemala. T. bvevbvostvis was identified from south of Puertecitos sporadically through the Gulf to the Galapagos Islands. Therefore, the geographic range of the two species appears to overlap. What we have seen may be two species living in approximately the same habitat, converging. In examining a large quantity of study material, we found specimens resembling the types of both species and we found lots in which we could not determine which species we had. If further work, including anatomical studies, should prove them one species, then Tellina veolusa Dali and Mevisoa mavgavita Olsson would be junior synonyms of Tellina bvevivostvis Deshay es.

Vol. XV (8) 1983 THE FESTIVUS 88 A NEAR CALAMITY BY BILLEE DILWORTH 6333 La Jolla Blvd. ^/171, La Jolla, CA 92037 For the past several years during my annual month on Maui, Hawaiian Islands, I have spent untold hours hunting for a Cypraea mauiensis Burgess, 1967. Hugh Bradner found one when we were diving together and I scoured the same area several times but the C. mawiensis eluded me. This past May, on the day before I was to leave Maui, I finally found my Cypvaea mauiensis . It was such a thrill. Since I was to be in Maui one more day, I put the cowry in alcohol but transported it dry. After I returned home, I thought soaking it in water for a couple of days would soften the animal's body enough to remove it. (Even the finest needle was too large to insert in the tiny aperture). Then the idea of blowing the animal out came to me. I gave one hard blow and some of the animal came out. I drew in another deep breath. I felt the shell start down my throat. In that split second I had the thought that some good Cypraea are taken from fish stomachs still in good condition. Would my mauiensis still be a shiny shell if it had to go through my digestive system? To my surprise and relief, the shell then came back up into my mouth! After finding my precious little shell and almost losing it again, it will hold a special place in my heart as well as in my shell cabinet. A CORRECTION TO "A NOTE ON MACOMA (PSAMMACOMA) ELYTRUM KEEN. 1958" BY BARBARA. W. MYERS, CAROLE M. HERTZ, JOYCE GEMMELL Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In the June 9, 1983 issue of The Festivus (XV(6) : 64-67) , the authors erred in their review of the taxonomy of Maooma (Psammaaoma) eZytmm Keen, 1958. We stated that the type material for TetZina eZongata Hanley, 1844 constituted the typological specimens of Maooma eZytrum Keen. This is not the case. TeZZina eZongata Hanley, 1844 is a primary homonym of T. eZongata Dlllwyn, 1823 and therefore must be permanently rejected (ICZN Article 59k). Instead of choosing a replacement name as we stated. Dr. Keen (1958) proposed a new species with tvne material deposited in the California Academy of Sciences. She placed Hanley’s species in synonymy thus negating the need for a new name to replace Hanley's preoccupied name. We wish to thank Drs. A. Myra Keen, Harold Yokes, William K. Emerson and Hans Bertsch for their comments and clarification of the problem. 89 THE FESTIVUS Vol. XV (8) 1983 CLUB NEWS FOR YOUR INFORMATION A NIGHT IN THE SOUTH PACIFIC The Club's Annual September party will be held on Saturday evening, September 17 at the home of Carole & Jules Hertz.

Vol. XV(8) 1983 THE FESTIVUS 90 FROM THE MINUTES SAN DIEGO SHELL CLUB MEETING - JULY 21, 1983 BY JOHN SAGE The July meeting came to order at 7:40 P.M. After new members and guests were welcomed, Ron McPeak introduced the evening's speaker, Jim ”Ace" Parnell whose presentation of "Diving Diego Garcia" was colored with extra tidbits of U.S. Navy life at sea, and was another photographic example of the exciting life in our seas. Our gratitude to Mr. Parnell. After the refreshment break, compliments of Rose D'Attilio and Marge Bradner, the June minutes were approved and Ron McPeak announced that the scheduled August speaker would be Richard Herrman. Because there had been a mixup. The Festivus had listed Mr. Herrman as the speaker in July. There was a lengthy discussion on the Botanical Gardens Foundations Fair to be held on September 18, 1983, in Balboa Park. Volunteers were requested to help in manning the Club display. The theme will be "Fauna and Flora of Baja California, Mexico," and volunteers may contact Marty Schuler. He will request indoor space to protect aquarium animals from the sun. There was also a discussion on the annual September party to be hosted by Carole and Jules Hertz. September 24th was selected as the date and the party theme will be Polynesian. [The date has been changed to September 17 by the Board because many members were unable to attend on the 24th. Ed.]. Carole announced that another shell was named for Dave Mulllner in the most recent issue of The Veliger in a paper by Leroy Poorman. Marty Schuler won the shell drawing.

AND OPERCULUM OF HOMALOCANTHA OXYACANTHA (BRODERIP. 1833) BY ANTHONY D'ATTILIO Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In December 1973, the late George E. Radwin with Mr. L.J. Bibbey collected specimens of Homaloaantha oxyaoantha while diving in 7-19 meters (approx. 20-60 feet) of water at Bahia Coastecomate , Jalisco, Mexico. This material, which was deposited in the San Diego Natural History Museum wet collection, contained three immature specimens (27-32 mm) which were free of encrustation. Since mature specimens of H. oxyaoantha are usually found entirely encrusted with limy marine organisms which obscure the microscopic sculpture and with the spires eroded or embedded with calcareous deposits, I took the opportunity to make a micro- scopic examination of the surface sculpture, protoconch, and operculum of these Immature specimens. One of the three specimens studied is shown in Figure 1. Its color is light ochre except for a whitish zone on the shoulder between the suture and the first row of spines. Figure 1. Apertural and dorsal views of immature specimen of E. oxyaoantha. Length: 30mm. , Maximum width: 27mm. Photo: D. Mulliner Vol. XV(9) 1983 THE FESTIVUS 93 The protoconch illustrated in Figure 2 consists of two and one half convex whorls. The character of any microsculpture could not be discerned since it had been somewhat abraded . The scabrous sculpture on the spines is shown in Figure 3. It appears like a long series of ruffles with the edges well elevated as in an accordion-pleated skirt. On the convex cords shown here, fine incised lines divide the ruffled sculpture. The unusual nature of the scabrous sculpture on the spines occurs in a somewhat simpler form over the entire shell. On the shell surface the transverse spiral cords have well developed erect scales and in the inter- spaces of the cords the scales continue as low, erect lamellae. The scales on the body are grooved as in the sculpture on the spines. The sculpture, so clearly expressed on these small specimens, is almost entirely lost through attrition; the result of the formation of foreign, calcareous deposits on more mature specimens. The operculum is subcircular with a lateral nucleus. Externally (Figure 4) the concentric sculpture consists of some well elevated lamellae, simple convex cords, and overlapping irregular and undulating layers of chitin especially on the surface near the nucleus. As in most purpurold operculae, there is a tendency to fold centrally on drying. Internally (Figure 5) the operculum is somewhat lustrous and divided centrally by a raised area which slopes down in both directions opposite the concentric sculpture (see arrow). My appreciation is extended to David K. Mulliner who took the photographs of H. oxyaaantha. Figure 2. Camera luclda drawing of the protoconch of H. oxyaeantha. SDNHM 81654 32X Figure 3.

MEXICO BY HELEN DUSHANE 15012 El Soneto Drive, Whittier, California 90605 Indian shell middens abound along the shores of Baja California, both on the Pacific Ocean and Gulf of California sides. One of the most extensive ones is along the Bahia de la Concepcion at approximately 26°43'N, 111°54’W, at a place called strangely, El Requeson. Why the Spanish, who are usually so apt with place names, chose to relate this area with cottage cheese is a puzzle. There seems to be no record of what the Cochim'i Indians called it in their language. El Requeso^n is a small sand spit connecting with a rocky bluff in Bahia Concepcion, Gulf of Galifornia, Mexico (Figure 1). Extending south, for at least twelve miles, on the west side of Bahia Concepcion, there is a continuous shell midden. At some places the shell debris reaches a depth of approximately eight or nine feet. Represented are specimens obtained from mangrove roots, rocky shorelines, cobble and sand beaches. Characteristic are the following pelecypods (bivalves). [Numbers pre- ceding the name of the shell refer to Keen (1971)] . KllO - GZycymeris gigantea (Reeve, 1843) K156 - Tinna rugosa Sowerby, 1835 K157 - Atrina maura (Sowerby, 1835) K162 - Pinatada mazatlanioa (Hanley, 1856) K174 - Ostrea patmuta Carpenter, 1857 K181 - Peaten vogdesi Arnold, 1906 K182 - Argopecten airaularis (Sowerby, 1835) K202 - Lyropeoten subnodosus (Sowerby, 1835) K210 - Spondylus oaleifev Carpenter, 1857 K244 - Cardita megastropha (Gray, 1825) K348 - Chama frondosa Broderip, 1835 K349 - Chama mexioana Garpenter, 1857 K363 - Traohyoardium panamense (Sowerby, 1833) K380 - Periglypta muttiaostata (Sowerby, 1835) K425 - Megapitaria squalida (Sowerby, 1835) K440 - Chione ealifoimiensis (Broderip, 1835) K616 - Tagelus calif ornianus (Gonrad, 1847) K630 - Semele flavesoens (Gould, 1851) In addition a few gastropods were observed. They were definitely in the minority. K607 - Strombus gracitior Sowerby, 1825 K608 - Strombus granulatus Swainson, 1822 K609 - Strombus galeatus Swainson, 1823 The above listing is not a comprehensive one of the mollusks taken by the Indians for food purposes, but shows only what was observed during a very limited time. There is no indication from the number of half shells on shore that this was ever a pearl fishery. Nor is there any indication that the natives had offshore fisheries, nor did they dive at great depths. The few tools scattered about are sharp edged , XV(9) 1983 THE FESTIVUS Q5 96 THE FESTIVUS Vol. XV(9) 1983 flakes of stone, broken from cobbles at hand; a few have been worked to create a better cutting edge. Indications are of a seasonal occupation with no fire rings or sooty earth present. Because this area lacks water for long periods of time, it is believed that the natives came from the foothills for a few days of low tides on forays to eat fresh shellfish and to dry the remaining harvest on the rocks. The dried fish were taken back to the rancher ias at the foot of the Sierra de la Gigantea. (Although in February 1975, rain fell for one full week at this locality, a man born and raised nearby told us that from 1966 to February 1970, no rain had fallen.) In subsequent years the same pattern of precipitation, or lack of it, seems to have occurred. Occas- ionally, during the fall months of hurricanes (Chubascos) off the Pacific coast a strong storm will cross the Sierra and deluge the area, but this is a rare happening. The absence of Olivaj OHveZZctj and other small shells used for adornment indicates that this was a food gathering enterprise rather than one that resulted in the making of ornaments. The steep, rocky bluff connecting with the sand spit, which at high tide is isolated and known as Isla Requeson, is completely covered at the top with valves of Spondylus aaleifer which are easily pried loose at low tide. Apparently, at one time, this was an important food source for the aborigines. Reference Cited KEEN, A. MYRA 1971. Sea Shells of Tropical West America, 2nd Edition.

Box 1390, San Diego, California 92112 THE lUCN INVERTEBRATE RED DATA BOOK Compiled by: Susan M. Wells, Robert M. Pyle and N. Mark Collins 1983. lUCN, Gland^ Switzerland Prepared with the financial assistance of The World Wildlife Fund and The United Nations Environment Programme ISBN No. 2-88032-602-X Price: $22.70. This is the latest in a series of Red Data Books (RDBs) published by the lUCN [International Union for Conservation of Nature and Natural Resources] one of whose principal functions is to "...collect data on threatened species and habitats in order to promote appropriate conservation action." Previous RDBs dealt with mammals, amphi- bians and reptiles. This one treats invertebrates; terrestrial, fresh water and marine including Protozoa, Cnidaria, Mollusca, Arthropoda, Bryozoa, and Echinodermata among the over 14 groups treated. It is the first of a series which will deal with inverte- brates and is not meant to be complete for any group included. Vol. XV(9) 1983 THE FESTIVUS 97 A fine Introduction discusses invertebrates generally, their characteristics, and the threats to their survival. The importance of invertebrates in the ecological pro- cesses is examined with information on past and current conservation efforts and suggestions for future measures. Following a list of status categories for the taxa, i.e. (E) endangered, (V) vulnerable, there is a compilation in systematic order listing all the threatened invertebrates included in this volume. Each group discussed has been researched. Besides an ample bibliography for the general information on each inverte- brate group, separate and adequate reference lists are included for each species treated within the larger group. The Mollusca is divided in three groups; terrestrial, fresh water, and marine. These three sections were compiled by Susan M. Wells. The six page general information section on the marine mollusks includes headings on Scientific Interest and Potential Value and Threats to Survival. Items on commercial value of the species are included in the Introduction. A point made under 'Conservation* deals with mariculture as a possible answer to over-exploitation and the increasing need for food. It advised (p. 74) "Considerable care needs to be taken in the establishment of aquacultural enterprises. Marine monocultures are subject to the same problems of increased risk of disease as are terrestrial monocultures, they may affect detrimentally the natural fauna in surrounding areas and in the case of mussels, can cause fouling problems..." The threatened marine mollusks listed are: Stvombus gigas Linne, 1758 Charonia tvitonis Linne, 1758 Doridelta batava (Kerbert, 1886) Trldacnidae species Hippopus hippopus (Linne, 1758) H ^ .poroetlanus Rosewater, 1982 Tridaona oroaea (Lamarck, 1819) T. derasa (Roding, 1798) T. gigas (Linne, 1758) T. maxima (Roding, 1798) T. squamosa Lamarck, 1819 CT (commercially threatened) R (rare) K (insufficiently known) I (indeterminate) refers to taxa either E, V, or R but where there is not enough information to determine which of the three is appropriate. I K V (vulnerable) V K I Each of the mollusks, or related group of mollusks, listed above is treated at some length. A description, population, distribution and habitat data with behavioural information, is given as known. Under a subtitle of Scientific Interest and Potential Value is found information on the strength of the species and its use in the particular localities throughout its range. Several pages deal with conservation methods, effec- tive and otherwise, which have been taken and proposals for the future. For Charonia tritonis , for example, the population density is unknown but it is rare where found. In a study of 81 reefs on the Great Barrier Reef, only 24 specimens were found. Out of 133 sites on 92 reefs in Indonesia, only two specimens were noted. No in-depth ecological studies had been done and attempts to rear the species in cap- tivity were not successful. Some comments were made concerning the Triton's role as destroyer of the Crown of Thorns starfish Aoanthaster ptanai. They note that C. tvitonis appears too uncommon to exert much control over the A. ptanoi populations. Additionally, seastars attacked by C. tritonis "have been found to survive," Still, very low populations of C. tritonis seem to correspond to infestations of the Crown of Thorns. Overcollection (such as that in Guam) has resulted in depletion of C. tritonis. It is also mentioned, though without substantiating data, that toxic residues from pesticides found in the tissues of C. tritonis may act to reduce the populations. They note that while this species is rare it is not certain that it is a "threatened" species since it is widely distributed and its larvae are long lived with "considerable dispersal abilities." Some countries have already protected the Triton's Trumpet. Its collection and export is banned in Fiji, the Seychelles and Queensland, Australia. Further protective measures are advocated and better enforcement of existing regulations. 98 THE FESTIVUS Vol. XV(9) 1983 I thoroughly enjoyed this book which, by its title, gave all indications of being dry, dull, and "educational." While it is not designed for every home bookshelf, it makes for some fascinating reading. Besides the small segment from the section on Mollusca (38 pages on marine mollusks) touched on here, some of the other groups were most absorbing since much of the general information was new to me. In the Cnidarians, for example, it states that the jellyfish Aequorea aequorea has a bioluminescent protein which "glows in the presence of calcium or strontium and is sensitive enough to enable detection of minute fluctuations in calcium concentrations in biological fluids." This book is certainly recommended reading, and might be considered as part of the library of those who work with or are interested in the interaction of these organisms and their environments. FROM THE MINUTES SAN DIEGO SHELL CLUB MEETING - AUGUST 11, 1983 Vice President Ron McPeak called the meeting to order. Richard Herrman, a Club member and Diving Instructor for New England Divers in San Diego, was our guest speaker. He shared with us some of his experiences as a diving instructor in the Caribbean, particularly in the Bahamas and on the Island of Guadeloupe. One of the highlights of his stay on Guadeloupe was collecting alive Pterynotus phyltopterus (Lamarck, 1822). Members also enjoyed the display of shells he had collected in the Caribbean. Following the refreshments (with delicious cookies provided by Billee Dilworth and Marilyn Perrin) there was a brief business meeting. The Minutes for July were accepted with no corrections. Our meeting for September will be the autumn party with the theme, "A Night in the South Pacific." It will be held at the home of Carole and Jules Hertz on September 17, beginning at 6 P.M. [See map for details.] The October program will be given by Bill and Marilyn Perrin who spent several weeks on St. Helena Island in the South Atlantic, historically famous as Napoleon’s place of exile from 1815-1832. Billee Dilworth gave a brief report on the WSM/AMU meeting in Seattle. Announcement was made that member David J. Myers, a graduate student in Marine Biology at Cal. State. Fullerton, and son of Barbara and John Myers, was the recipient of the WSM scholarship award for 1983 and also had received a scholarship award from the Hawaiian Malacological Society. The shell drawing was won by Frank King.

THE FESTIVUS Vol. XV(IO) 1983 RECENT SPECIES OF THE GENUS PTEROCHELUS (EiURICIDAE: MURICINAE) BY ANTHONY D'ATTILIO and BARBARA W. MYERS Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 SUBFAMILY: Muricinae Rafinesque, 1815 Genus: Ptevochetus Jousseaume, 1880 Type species: Murex acanthopterus Lamarck, 1816 by original designation The genus Pterochelus is directly related to Pterynotus Swainson, 1833 in its trivaricate shape, open siphonal canal, radula, and operculum. Murex acanthopterus Lamarck, 1816, the type of Pterochelus is shown in Figure 1. Figure 1. Murex acanthopterus Lamarck, 1816 from Bruguiere’s Encyclopedie methodique part 23, p. 417, fig. 2a and 2b by Lamarck Pterochelus is separable from Pterynotus by the morphology of the strong, open shoulder spine. The open portion of the spine is a channel centered on the ventral side which, for a period of the shell's growth, flows directly into the aperture. At maturity, the connection between the spine channel and the aperture is sealed off by the apertural lip forming a trough whose perimeter seals off the aperture from the open spine. Seee Figures 2 and 3. Attached to this shoulder spine, both anteriorly and posteriorly, is a wrinkled flange reaching from the suture to the canal termination. This can be seen in Figure 1. Figure 4 is a radula drawing of Pterochelus acanthopterus Lamarck, typical of the groups Pterynotus and Pterochelus. The species assigned to this genus are all characterized by this spine form and are entirely distinct from all species placed in Pterynotus (D'Attilio & Myers 1983). Radwin and D'Attilio (1976) retained Pterochelus as a full genus not as a subgenus of Pterynotus . Vol. XV(IO) 1983 THE FESTIVUS 101 Fig. 2.

Note: Typhis angasi Crosse, 1863, placed in Prototyphis Ponder, 1972 as type species, sometimes has been assigned to Pteroahelus by authors. However, in spite of some of the shell similarities to other Australian species of Pteroahelus ^ Prototyphis angasi has the distinctive traits of the typhine tube characteristic of Typhinae (D'Attilio 1982).

MYERS, CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In examining juvenile tellinid specimens in the Gemmell collection, it was necessary to compare typological material of several species. The holotype of TelZina ooani Keen, 1971 was borrowed, and while it was at the Museum it was pV\otographed and camera lucida drawings were made. The study of this type material made it possible to separate specimens of T. aoan'i ^ adult and juvenile, from other tellinid species in the Gemmell collection. Tetlina coani was described by Keen (1971). It is shown here together with a copy of its museum label in Figures la and Lb. The holotype measures 6 . 5mmL x 3.7mmH. The species is distinguished by its small size and the pink rays running obliquely from the beak to the ventral margin. The camera lucida drawing of the exterior of the right valve of the holotype shows the raised lirae over the entire exterior surface of the shell. See Figure 2.

The pallial line and sinus were only partially visible in the holotype. These features are shown in a camera lucida drawing of the left valve of a Gemmell specimen (G-453) in Figure 4. The dentition in this species is shown in Figure 5. The dentition consists of two cardinals, one bifid in each valve. The posterior cardinal bifid in the right valve and the anterior cardinal bifid in the left valve. The right valve has a large lateral anteriorly and a faint posterior depression (late ral) ; the left valve has no laterals. Fig. 2.

Vol. XV(IO) 1983 THE FESTIVUS 105 "A NIGHT IN THE SOUTH PACIFIC" By MARILYN PERRIN Because of the party on September 17, 1983, there was no regular meeting this month. The theme of the party was "A night in the South Pacific," and it was held at the home of Carole and Jules Hertz in their lush and beautifully landscaped back- yard. With the wealth of exotic plants and South Pacific decorations, one had the feeling of actually being on an island. We had an excellent turnout: there were approximately 55 people present. Everyone came in costume, and Dave Mulliner served his famous Island Punch. The dinner was absolutely delicious and included Chicken South Pacific^ rice, Puu Puus , fruit salad, and wonderful desserts. The dinner was followed by entertainment by some of the Club members. Twila Bratcher performed a hula to "Keep your Eyes on the Hands," Marty Schuler showed us how to "tinikle", Ruth Hertz sang some South Pacific folk songs, and Marily Perrin performed a hula to "Hukilau." Also, Marilyn gave a short course on Tahitian dancing to those members who were willing and brave enough to participate after a very large dinner. The company was delightful, the setting and food great, the weather perfect, and, needless to say, the party was a tremendous success! FOR YOUR INFORMATION ANNUAL CHRISTMAS PARTY The Club's annual Christmas Party will be held on Saturday evening, 10 December 1983 at the Mariner Officers' Club. Details will be in the November issue of The Festivus. Mark your calendars and plan to attend.

Highland, Phoenix, Arizona 85018 In May 1980, Paul and I were dredging at Bahia de Los Angeles, Baja California Norte, Mexico. We camped at La Gringa and made many hauls between Smith Island and the shore. Our equipment consists of a 14 ft. aluminum boat and a 25 hp. motor. We use 3/8 in. nylon line and an 18 in. wide dredge designed and built by Paul. We can dredge well at 100 m. with this outfit by adding extra chain at the dredge to keep it down and by using more line than we would for a shallower depth. We use nylon line because it sinks instead of floating and is a lot easier on the hands. It does stretch, so the more line out the less "feel" for what is happening at the bottom. The water gets deeper (182 m. ) at the north end of the Smith Island channel (113032'W; 29°6'N). We could get the dredge down only by using 1200 ft. of line and bringing the boat to a complete stop to allow the dredge to settle to the bottom. Because of the stretch in the line, there is almost no "feel” at this depth. We don't know if we were actually dredging or if, and this seems most likely, we were just getting a single grab as the dredge left the bottom. In any event, bringing all that line back into the boat was well worth the effort. Each time the dredge broke the surface it looked almost empty. A scattering of small, round, blackened pebbles barely covered the bottom. In each load there was at least one very special shell, some of which turned out to be undescribed and will be the subject of a further report. Two of the Muricidae are of special "" interest; Pteropurpura maoroptera (Deshayes, 1839) and Murexiella mildredae Poorman, 1980. Pteropurpura maoroptera (Figure 1) is known from Monterey, California to Todos Santos Bay on the outer coast of Baja California (Radwin & D'Attilio 1976). Our live, 37 mm specimen taken at 182 m. extends the range into the Gulf of California. Murexiella mildredae (Figure 2) is known only from the type area off Tetas de Cabras, Sonora, Mexico in 100 m. (Poorman 1980). Our live taken, 23 mm. specimen extends the range across the Gulf and to 182 m. In October 1981 we were dredging farther south. We camped at Puerto Escondido, Baja California Sur, Mexico and used the same boat and equipment. Danzante Island lies just off Puerto Escondido. At the south end of the island (25°45'N; llloi5’W) in 30 to 45 m. of water, the bottom consists of many broken shells and some gravelly rocks. At this location we took a dead specimen of Nipponotrophon galapaganus (Emerson & D'Attilio, 1970). Fig. 1. Pteropurpura maoroptera (Deshayes, 1839) Photo: Mulliner Vol. XV(ll), 1983 THE FESTIVUS 108 (Figures 3-4). The species is known only from a very few specimens taken at Santa Cruz and Hood Islands, Galapagos Islands, Ecuador in 150 to 200 m. Our 38 mm specimen extends the range into the Gulf of California. I would like to thank David Mulliner and Paul Skoglund for the photos and Donald Shasky for allowing me to check the identity of Nipponotrophon galapaganus with his paratype.

Highland Avenue, Redlands, California 92373 Adapted from a paper presented at the annual meeting of the Western Society of Malacologists — 1983 This paper is Part II of a paper I presented last year at the Western Society of Malacologists meeting in Redlands, California [see Festivus 15(2) :27-28] . I had not expected that there would be a second part — at least not so soon. In that paper I reviewed the literature that appeared since Dr. William K. Emerson's paper with a similar title in Volume 92 of the Nautilus dated April 1978 and Dr. Hans Bertsch's nudibranch paper in the same journal in Volume 93 in 1979. In my paper, I cited additional species that I had collected at La Plata Island, Ecuador and Taboga Island, Panama. I also reviewed a paper by Robert Robertson and one by Hans Bertsch and L.J. Bibbey. Dr. Michel Montoya, presently of Managua, Nicaragua, has a paper in press titled "Los Moluscos Marinos de la Isla del Coco, Costa Rica. Lista Anotada de Especies." (The Marine Mollusks of Cocos Island, Costa Rica. An Annotated List of Species) Dr. Montoya, a native Peruvian, is an agronomist with the Inter-American Institute for Cooperation on Agriculture. His paper is a complete literature review. He re- ports 16 species of bivalves, 89 gastropods, 4 chitons, and 9 cephalopods. No scaphopods or nudibranchs have been reported from the island. This is a total of only 118 species. This past April, I was privileged to be able to spend 6^ days SCUBA diving around Cocos Island. As far as I can determine, I was the first diver-malacologlst to explore these waters — in other words, virgin territory. In June of this year Dr. Montoya also dove there. (I worked the hard bottom and he the soft bottom.) This paper cites new Indo-Pacific records from Cocos Island which has been virtually undiscovered by malacologists. It is located approximately 300 miles south by southwest of Puntarenas, Costa Rica and is the largest uninhabited Island in the world. It is about 20 square miles. Its annual rainfall is 22 feet (7000 mm). It has 200 waterfalls and a number of bays and inlets. In April the water temperature at all depths was 85° F. My diving was done from the 82 foot motor-schooner, Victoria, built in Sweden and manned by a Swedish crew. It takes up to eight divers from Puntarenas to Cocos Island. The accomodations are adequate and the food is excellent. The following seven species have not been previously recorded in the Eastern Pacific . 1. Viriola ahhotti (Baker & Spicer, 1935) This was described from Samoa and subsequently reported living in Hawaii by Dr. E. Alison Kay. 2. Soalenostoma subulata (Broderip, 1832) According to Dr. Anders Waren of Sweden, this species has 18 synonyms. Up until now this had been found in all tropical seas with the exception of the Eastern Pacific. Vol. XV(ll) 1983 THE FESTIVUS 110 3. Cypraea talpa Linnaeus, 1758 Altogether 1 found 5 living specimens of this and Captain Richard Callaway (of Balboa, Panama) who was with me, found 2 more. 4. Cypvaea n. sp. This species is in press in the Venus . It is being described by Dr. Burgess who tells me that this is found from Australia through the central Pacific. He has examined this shell and confirmed its identity. Captain Callaway also collected one specimen. 5. Charonia tritonis (Linnaeus, 1758) This unique specimen was found living at 120 ft. 6. Favartia gavrettii (Pease, 1869) Up until now, this has been known only from the Hawaiian Islands. I have had an unidentified Favartia in my collection for some time from La Cruz de la Huantecoxtle, which is approximately 30 miles north of Puerto Vallarta, Mexico, which also proves to be this species. 7. Persicula pulohella (Kiener, 1834) This was a single dead specimen. The following four species have been found on other offshore islands, but not previously at Cocos Island. 1. Bursa granularis (Roding, 1798) This has been reported from Clipperton Island. The largest specimen I collected measures 72 ram. 2. Cypraea oaputserpentis Linnaeus, 1758 This has also been reported from Clipperton Island. 3. Fseudooypraea adamsonii (Sowerby, 1832) This has been known from the Galapagos, and I reported collecting one specimen at La Plata Island, Ecuador last year. 4. Coralliophila neritoides (Lamarck, 1816) This is known from the Galapagos and Clipperton Island. It is abundant on stony coral heads. A pertinent reference seems to have been previously overlooked by those of us who are Interested in the crossover between the tropical Eastern Pacific and the Indo- Pacific provinces. While working on something else, I chanced to review a paper by Couturier in Volume 55 of the Journal de Conchyllologie published in 1907. Couturier’s paper, "Etude sur les mollusques gastropodes recueillis par M.L.G. Seurat dans les archipels de Tahiti, Paumotu et Gambier," is a discussion of a large collection of mollusks collected by Seurat in French Polynesia. In it he lists the Panamic Rissoina saatariformis C.B. Adams, 1852 as having been found on the island of Rikitea. In the same paper. Couturier also described a variety of Rissoina zettneri (DeFolin, 1867), another Panamic species, which he called Rissoina zettneri var. tuamotensis. 1 have a number of species from Cocos Island as yet not Identified. Several of these are new species one of which is a specimen of a Rissoina that is unlike any of the known Eastern Pacific species. It is very close to an unidentified species that I collected in Tahiti this past January but they are not conspeclfic. Though the scleriform shape is much the same in both species, the Tahitian one has rather strong axial threads not found in the species from Cocos Island. I also collected an olive that I had not seen before. In summary. Dr. Montoya and I are adding 7 additional Indo-Paclfic species to the ever enlarging list of Indo-Pacific mollusks that are found in the tropical West American fauna. We are, at present, preparing an update of his Cocos Island check- list that will increase the known species by at least 100. It may be of Interest to you that Dr. Montoya and I will be returning to Cocos Island next .Ifarch for 21 days. During that time we will have the best low tides of the year which will give us an opportunity that we did not have previously. I expect, that from this proposed trip, there will be a Part III under this title next year. Ill THE FESTIVUS Vol. XV(ll)' 1983 THE GENUS PTERQPURPURA JOUSSEAUI^E. 1880 (ElURICIDAE: OCENEBRINAE) BY ANTHONY D'ATTILIO and BARBARA W. MYERS Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 ‘ FAMILY: Muricldae Raflnesque, 1815 SUBFAMILY: Ocenebrlnae Cossmann, 1903 GENUS: Pteropurpura Jousseaume, 1880 Type, Murex maavopterus Deshayes, 1839 by original designation The genus Pteropuvpura is assigned to th subfamily Ocenebrlnae based on the structure of the radula, the purpuroid operculum, and the sealed siphonal canal open only at its termination. The method of canal closure in the Ocenebrlnae is figured in Myers & D'Attilio (1981) and D’Attilio (1973). The type of the genus, Pteropurpura macroptera (Deshayes, 1839) has a fusiform trivaricate shell with the varices developed into flanges. The aperture is very weakly dentate and the siphonal canal is moderately long, sealed, and bent to the right. The surface of the shell is smooth to scabrous (Figure 1). Emerson (1964) clarified the nomenclatural and taxonomic problems of Murex maaropterus and photographed the holotype. The radula of P. maovoptera is Ocenebrlnae in overall appearance and is figured in Radwin & D’Attilio (1976). The operculum of P. macroptera is purpuroid, oval and thin. See Figure 2. Examination of a juvenile specimen from the B. Myers collection showed the protoconch to have 2i^ smooth convex whorls. The first Ih, to 2 postnuclear whorls have two nodulose cords. There is no sign of varical formation until the third postnuclear whorl. See Figure 3. Superficially Pteropurpura resembles Pterynotus Swainson, 1833 which also has a trivaricate shell with the varices developed into wing-like flanges. Pterynotus, however, has a Murlcinae radula and operculum and the siphonal canal is open along its length. Fig. 1.

After introductions of new members and guests, Ron presented the evening's speaker, member Bill Perrin. Bill, a specialist in dolphins, and his wife, Marilyn had spent a working vacation on the island of St. Helena in the South Atlantic. Bill gave an informative and most enjoyable program on the island with comments on the fauna, flora and people of the island, as well as showing slides of rare shells from St. Helena and South Africa (where they also stopped enroute) . A display of shells and artifacts from St. Helena were also on display. Bill's dry humor and discerning camera eye made this an outstanding program. The business meeting followed the refreshment break. Arrangements for the annual Christmas dinner party were discussed. It will again be held at the Mariners Club and will be on December 10 (For details and map, see last page of this issue. Ed.). Checks for $12.00 to cover dinner and gratuity must be received by Treasurer Wally Robertson by December 5, 1983. The Board, acting in its capacity as nominating committee, presented the following slate of officers for 1984. President: Recording Secretary: Vice President: Richard Herrman Treasurer: Martin Schuler Corres. Secretary: Marilyn Perrin Additional nominations will be entertained at the November meeting at which time the members will elect the officers for 1984. The shell drawing for October had to be postponed until November because the Club locker could not be opened. Those who signed the attendance sheet for the October meeting will be eligible. IN MEMORIAM We report, with sadness, the passing on October 2, 1983 of Morris Levine of Jamaica, New York, a member of both the New York and San Diego Shell Clubs. Morris and Anita wintered here in San Diego and regularly attended our meetings. Our deepest sympathy is extended to Anita. Morris was a longtime collector and has bequeathed his shell collection to the San Diego Natural History Museum. THE FESTIVUS DOES NOT PUBLISH A DECEMBER ISSUE. THE ANNUAL CLUB CHRISTMAS PARTY — DECEMBER 10, 1983 The Club Christinas party will be held at the Mariner Officers’ Club, 32nd St. Naval Station in the Destroyer Room. The festivities begin at 6:00 P.M. with no host cocktails. Dinner will be at 7:00 P.M. The menu is as follows: Dinner salad, Roast Prime Ribs of Beef, Baked potato. Green beans almondine. Rolls, Coffee or Tea. The Club will provide complimentary dinner wine. Following dinner and the traditional Club shell gift exchange, there will be dancing to the "mellow" music of a band in the main room. The cost for the evening is $12.00 per person. Deadline for reservations is Monday, December 5. Checks should be made payable to The San Diego Shell Club, Inc., and given to Treasurer Wally Robertson or sent to the Club address (front page). Remember to participate in the traditional shell gift exchange. Bring your gift wrapped shell to place under the tree. Place data and name inside the package only. On the outside place only general locale i.e. Pacific, Caribbean etc. Numbers will be drawn and those bringing a shell gift will choose one from under the tree. It will be a great party, as usual.

STILLMAN BERRY IN HIS "LEAFLETS IN MALACOLOGY" BY CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 INTRODUCTION In November of 1946, S. Stillman Berry began the private publication of his LEAFLETS IN MALACOLOGY which he instituted to facilitate the "publication and dissemination. .. of new mollusks of special Interest under study" primarily by him. LEAFLETS IN MALACOLOGY continued for twenty- three years concluding with Volume 1, Number 26 in December 1969. During these years. Dr. Berry described 99 marine molluscan species, renamed one species, and named 19 new genera in the "LEAFLETS." However, only two of the species were figured and few of the types have been illus- trated since. It is the purpose of this paper to figure all of the types of the species named by Dr. Berry in the "LEAFLETS," with the exception of the eight species of Octopus. This project would not have been possible without the efforts of Leroy and Forrest Poorman who saw the need to Illustrate Dr. Berry's type specimens and had photo- graphed all but two for the species described in the "LEAFLETS" (excluding Octopus species). Most of the photography was done between July and December of 1971. In Leroy Doorman's words, "...Many of the types were photographed at Stanford [University] through the courtesy of Dr. Myra Keen. Fifty-nine specimens were photographed in one day. These specimens have since been placed in CAS [California Academy of Sciences]', ...we spent much time at Berry's home photographing. He gave us oral permission to use the slides in any way we wished. He said that they should be published but that the cost was too high, even for him... We went through the special chest in which he kept his types when we were photographing there." The types of Cirsotrema pentedesmium and Pedicutaria ( calif omica'l phase or form?) ovutiformis were photographed by David K. Mulliner. He also gave of his time and talent in preparing the black and white prints from Leroy Doorman's original color slides . DISCUSSION In determining the scope of this paper, I decided that the inclusion of the known repositories of the Berry typological material would be of value. In this, the Poorman slides were again of considerable help since, for example, the slides of holotypes which had already been deposited at Stanford University were so noted. The catalogues of molluscan type specimens by Richards & Old 1969, Smith 1978, Sphon 1966, Sphon 1971, and Wilson & Kennedy 1967 were then consulted for further information on the location of Berry type material. Further, in the "LEAFLETS" 1(14) :75 (July 19, 1957), Dr Berry wrote, "Holotypes of all the new forms, except as otherwise noted are Intended to be deposited in the type-collection of the Page 2 THE FESTIVUS Vol . XV : Supplement Department of Paleontology, Stanford University. Paratypes are in the author's collection, although they will be shared as far as the material permits with the U.S. National Museum, San Diego Museum of Natural History, Los Angeles County Museum and perhaps some other collections." From this beginning, a search was made to confirm the repositories of much of the type material and to locate additional Berry type material for species named in the "LEAFLETS." Dr. Berry frequently specified the intended recipients (museums) of the type material of the species he described. Using this information, inquiries were sent to those museums. Each institution was asked to check its collections for the type material in question. They were asked for the quantity of material for each species and their museum catalog numbers. The author personally checked the type collections of the San Diego Natural History Museum, Los Angeles County Museum of Natural History, Santa Barbara Museum of Natural History, and the California Academy of Sciences. In reviewing the repositories for the Berry type material, it was learned that Dr. Berry sometimes deposited parts of a single type specimen in more than one collection. For the holotype of Stenoplax isoglypta, as an example. Dr. Berry (p.73) deposited one plate in the National Museum of Natural History (USNM 612205, sixth plate), one plate in Stanford University (SU 8649) (designated a paratype in earlier literature) , and retained the remaining plates in his collection (Redlands 19160) . Further requests for information concerning other type material for species described in the "LEAFLETS" were also sent to the museums. In this regard, I received a reply from the Tromsa Museum to my request for information on a paratype of Barbatia rostae which Dr. Berry had intended to deposit there. Dr. Wim Vader, Curator, kindly sent photographs of their specimen and its accompanying label. yFiile the photographs indicate the specimen to be BcLPbcL't'io. TOS'tcL& , I have listed their specimen as "possible paratype" since proof of its status as a paratype is lacking. The information in this paper on the cephalopod type material referred to in the "LEAFLETS" was obtained through the efforts of Dr. F.G. Hochberg of the Department of Invertebrate Zoology, Santa Barbara Museum of Natural History, who with Dr. Clyde Roper of the Department of Invertebrate Zoology, National Museum of Natural History, began organizing Dr. Berry's cephalopod type collection during August 1983. This type material was then sent to the National Museum of Natural History , Smithsonian Institution to be accessioned in their type collection (Hochberg, pers. comm). Mr. Mike Sweeney of the Department of Invertebrate Zoology of that institution provided me with their catalogue numbers for these specimens. While all the material had been preserved as a wet collection, some had dried and one lot of 21 paratypes of Ootopus fitohi has still not responded to museum^ efforts to reconstitute the specimens. This lot has not yet been catalogued (Mike Sweeney, pers. comm). Curiously, there are 31 paratypes of this species in the collections of the USNM and CAS and only 27 listed in the "LEAFLETS." The location "Redlands" with the Berry collection number is listed for species noted by Dr. Berry for which I was unable to locate any repository. Table^^I is a summary of the cephalopod species described by Dr. Berry in the LEAFLETS. For the species listed below, the author was unable to locate the repository (les) of the holotypes. Based on Dr. Berry's quoted statement above, I assumed that the holotypes of these species would have been deposited at Stanford University. Since the Berry material deposited at Stanford University is now on permanent loan at the California Academy of Sciences, Jules Hertz and I searched their collections for this material in December 1983. None of those listed below was located.^ They may still be in the Berry collection at Redlands though not so noted in the LEAFLETS. I Vol. XV: Supplement THE FESTIVUS Page 3 have listed them as ”?Redlands (no number given)." They are listed below in the order of their appearance in the "LEAFLETS."

Each entry is listed with its original orthography; an [H] or [P] next to the name indicates that the specimen figured is a holotype or paratype. The date, volume, and page number(s) of the original description appear beneath the species name followed by the dimensions of the holo- type and the type locality. The measurements of all but three species {Nomaeopetta rnyvaBj Muricanthus aatl'idinus j and Pleuroliria artia) are those given by Dr. Berry in the "LEAFLETS." The length dimension of the holotypes of the other three species, not given by Dr. Berry, are those of the author. The repositories of the holotype and paratypes of each species are also listed, when known. Paratype material in private collections is not considered here since its ready availability for study by workers in the field cannot be assured. In the case of the type material which was donated to Stanford University (SU) and is now on permanent loan at the California Academy of Sciences; the Stanford University (SU) number appears first with the six-digit California Academy of Sciences (CAS) number appearing in brackets. In cases in which the specimen was deposited in the CAS prior to their current numbering system, the original CAS number appears first with the new six-digit number in brackets. Other holotypes are in the Berry collection at this time and are listed in the following pages as "Redlands" with the numbers assigned to them by Dr. Berry for his private collection. A brief synonymy is included for the species, when applicable. A chronological listing of titles by Dr. Berry in the "LEAFLETS” is on Page 41, and is followed by a bibliography and an index to the Berry species.

Foremost of these are Leroy and Forrest Poorman who made their slides and note cards available as well as giving me background information for the project. The black and white prints and the original photographs of two of the type specimens were done by David K. Mulliner, to whom I record my special thanks. My gratitude is extended to the following people who were kind enough to look for Berry type species in their respective institutions and provide me with catalogue numbers for those in their collections: Kenneth Boss and Carey Westermann (MCZ) , William K. Emerson (AMNH) , Joseph Rosewater (USNM) , Paul Scott (SBMNH) , Robert Van Syoc (CAS) , Solene Morris (BMNH) , and Wim Vader (TM) . I thank Eric Hochberg (SBMNH) who looked for the Octopus types at Dr. Berry’s home and who sent me detailed information on what he found. My thanks also to Mike Sweeney (USNM) who was good enough to give me their catalogue numbers by phone when I belatedly realized I had neglected to request them. Barry Roth, Helen DuShane, Eugene Coan, and A. Myra Keen were kind enough to help in locating the type of Ctrsotrema pentedesmtum for which I am grateful, and James H. McLean and Gale Sphon graciously made the LACM collections available to me to check type species. Barry Roth and Robert Van Syoc also gave generously of their time during my visit to the CAS to confirm types in their collection and secure their new catalogue numbers. My appreciation goes to Anthony D'Attillo and George Hanselman who advised me on the muricid and chiton species respectively, and to my daughter, Suzanne Hertz, who designed and prepared the cover page. I am indebted to James H. McLean for his encouragement and for his review of the paper. To Myra Keen who also reviewed the paper, offering helpful suggestions on the material deposited at Stanford University and on fine points in the text, I offer my sincere appreciation. More than anyone, my gratitude goes to Jules Hertz; he not only encouraged me in the project but assumed the roles of critic and proofreader. Without the help of these many people, this project could not have been under- taken and I am grateful to them for their assistance; however any errors in the paper are the responsibility of the author.

GILLINGHAM | Kelco, Division of Merck, Inc., 2145 East Belt Street | San Diego, California 92113 | My diving partner and I had finished loading our gear into my father's Cessna 180 float plane. We would soon be diving for the world's largest burrowing bivalve the Geoduck Clam, Fanopea generos^ (Gould, 1850), sometimes misspell Panope generosa. The Geoduck, which ranges from Baja California to Alaska, is abundant in Puget Sound and British Columbia's inne waters. Our destination was the west shore of Hood Canal, across from the village of Seabeck in Puget Sound (Figure 1) . After a short flight from American Lake, just south of Tacoma, we settled the float plan down on the quiet waters of the Hood Canal. It took us only a short time to prepare our diving gear and slip into the calm water We concentrated our search for th Geoduck along the gently sloping sandy bottom at depths of 15 to 3 feet. The sandy bottom was punc- tuated by many paired holes of Geoducks (Figure 2) . They were everywhere. We began to dig and discovere- how this clam received its name. Geoduck (Gooey-duck) is derived from the Nisqually Indian word, queduc, which means "dig deep." The clams live permanently buried in the soft substrate at an average burrow depth of 20 inches in the Hood Canal (Anderson 1971). Older individuals are generally at least 30 inches below the sur- face (Kozloff 1974). Adult Geoducks are unable to actively burrow to escape predators, like divers. The clams do give the Impression of burrowing when siphons are withdrawn deeper into the burrow. After persistent digging, we finally reached the bottom of the burrow. The clams Figure 2 Siphons of Panopea generosa in the sandy substrate. I Vol. XVI (1) 1984 THE FESTIVUS Page 3 Figure 1. Water ways of Puget Sound, Washington. Page 4 THE FESTIVUS Vol. XVI (1) 1984 we captured were about average in size, approximately two pounds. Geoducks as large as 13 pounds have been collected, and are believed to live to be more than 100 years old. Shaul and Goodwin (1982) confirmed that the age of Geoducks could be estimated by counting annual internal growth rings. They determined a mean age of 28 years for an undisturbed population of these clams at Port Gamble, Washington. Geoduck siphons are much too large to be retracted into the shell (Figure 3) but are easily retracted into the burrow. i 6 6 6 6 6 6 Figure 3. This photograph shows the enormous size of the Geoduck, The body is much too large to be fully retracted into its shell. (Photo from "Washington State Shellfish" Washington State Dept, of Fisheries) Siphons are frequently extended up to or above the substrate surface while the clams filter-feed on plankton (Figure 4). When clams are feeding with extended siphons, they are easily observed by divers. Goodwin (1977) found older clams with siphons three inches across. Siphons may also be completely withdrawn below the surface and the siphon holes filled with sand, mud, or detritus, leaving no trace of the Geoduck. The number of siphons "showing" varies from season to season. Goodwin (1977) found that only 5% of the Geoduck population was observed in study plots during January while 59.8% were observed in May. Fortu- nately we had planned our Geoduck hunting trip during May, when the population was easily observed. Geoducks were once thought to live only in the low inter- tidal zone where, during the twenty or so extremely low tides each year, they were dug by hand. In 1960, navy divers working in the Hood Canal located huge numbers of Geoduck necks pro- truding from the bottom. Geoducks have been found to depths of 350 feet (pers. comm. D. Jameson, Wash. Dept. Nat'l Resources). In 1967, the Washington State Department of Fisheries began inventories of potential commercial Geoduck resources in Puget Sound. These surveys were limited to shallow water (18-60 feet) areas having a high- probability of dense clam populations. Over 34,000 acres of Geoduck beds have been Identified including major and commercial beds totalling 19,545 acres with 280 million pounds of clams. Currently 8,378 acres with 165 million pounds Figure 4. Drawing shows relationship of siphon and neck to shell of Geoduck when extended for feeding. Vol. XVI (1) 1984 THE FESTIVUS Page 5 of Geoducks have been classified as commercial. The Washington State legislature made the Geoduck clam a commercial species in 1969 and a commercial fishery began in 1970 with the landing of 400,000 pounds of clams. Landings peaked in 1977 when 8.6 million pounds were harvested commercially (Shaul and Goodwin 1982). Geoduck harvest is co-managed by the Department of Fisheries (WDF) and the Department of Natural Resources (DNR) . The fishery is managed to allow maximum harvest without harming the population. The DNR makes available approximately five million pounds of Geoducks annually. This is considered the maximum sustainable yield (MSY). The MSY for Geoducks in Puget Sound is estimated at 1.5 to 3.0 percent of the harvestable stock annually. Reharvest does not occur until the Geoduck abundance in the bed has recovered to commercial densities. Studies by the WDF Indicate that recruitment of new clams is the major factor limiting the productive potential of the population. Geoducks are broadcast spawners, releasing eggs and sperm in the water where fertilization occurs. The larvae drift with the currents for four to five weeks and then settle on the soft substrate. The small clams burrow into the substrate to depths of one foot within the first year. Although the Geoducks grow rapidly and reach harvestable size of about 1.5 pounds in four to ten years, it could take decades to replace a population. Harvesting from waters less than 18 feet and from areas less than 200 yards from shore is prohibited to insure an Inshore spawning population. The WDF and DNR are attempting to grow Geoducks to a more substantial size under hatchery conditions for future planting in Geoduck beds. Artificial planting could benefit the industry by increasing the maximum sustainable yield and reducing the rotation time of commercial beds. Artificial planting could also benefit recreational clamming by restocking depleted intertidal areas. After spending a beautiful afternoon on the quiet shores of Hood Canal, it was now time to depart. After another short flight home, we enjoyed a delicious meal of the sweet meat from the Geoduck clam. LITERATURE CITED ANDERSON, A.M. , JR. 1971.

Box 1390, San Diego, California 92112 Great quantities of Phytlonotus erythrostoma (Swainson, 1831), numbering in the thousands and fished for human food consumption^ are obtained at Bahia Concepcion, Baja California. The empty shells are then sold as curiosities or specimens for shell collectors. Figure 1 illustrates a typical specimen of P. erythrostoma. An ususual specimen of P. erythrostoma from Bahia Concepcion was brought to my attention by L.J. Bibbey of Imperial Beach, California and Denis Brand of Van Nuys, California. Although normal in sculpture and form for the species, the pink aperture shows a rich, red-brown blotch over the posterior parietal region with three prom- inent brownish spots within the outer lip. See Figure 2. The apertural coloring of this specimen of P. erythrostoma is the same as that of P. regius (Swainson, 1821) See Figure 3. The biological explanation for the aberrant coloring in P. erythrostoma is not clear. Figure 1. Phytlonotus erythrostoma Figure 2. P. erythrostoma from Bahia SDNHM 23006 Concepcio^n, Baja California L.J. Bibbey collection Vol. XVI (1) 1984 THE FESTIVUS Page 7 The aperture and parietal inductura of P. erythrostoma varies from deep rose to pale pink to white with occasional specimens having an exterior sculpture of a row of knobby axial ridges between the frondose varices. The exterior sculpture of P. reg-ius differs from P. erythrostoma in having no axial ridges between the frondose varices. It may be added here that P. margaritensis (Abbott, 1958), from the southern Caribbean, normally has various tones of yellow ochre or more rarely pink in the aperture. widespread P. pomum (Gmelin, 1791), of which P. margaritensis is at times considered a variety, generally has three varices with strong axial ridges mid- way between the varices. The apertural coloring of P. regius also occurs occasionally in specimens of P. margaritensis. The specimen of P. margaritensis shown here in Figure 4 has the P. regius coloring and 5 varices. This specimen, from Porlamar, Venezuela, was donated to the San Diego Natural History Museum by John Q. Burch of Los Angeles. This same specimen was illustrated in MUREX SHELLS OF THE WORLD by Radwin and D’Attilio (1976) on plate 16, figure 6. Figure 3. Phyllonotus regius SDNHM 81700 Figure 4.

THE ANNUAL CLUB CHRISTMAS PARTY BY I'lARY Me PEAK Halls were decked with poinsettias when the Club met for the Christmas party at the Destroyer Room of the Mariners Club. The m.ood was as festive as outgoing president, Pat Sage's dark red and gold Thai silk dress. After a delicious dinner of prime rib, baked potato, green beans, and salad, we were entertained by Master of Ceremonies, Frank King. Frank said he couldn't remember jokes, but he had us laughing without them. Everyone participating seemed pleased with the gift exchange. John and Pat Sage presented exotic gifts to the outgoing board; and the incoming board, headed by new president, Jules Hertz, was welcomed with applause. 'Many thanks' to all who made the Christmas party such a success. The food was good, the table decorations beautiful (thanks to June King), and the company was excellent .

Page 11 THE FESTIVUS Vol. XVI (2) 1984 VAVA'U '83 A TRIP TO THE SOUTH PACIFIC KINGDOM OF TONGA BY DAVID K. MULLINER, MARGARET MULLINER, HUGH BPADNER, MARGE BRADNER, MIKE ANDERSON, JAYNE ANDERSON c/o 5283 Vicki Drive, San Diego, California 92109 After a year of planning by Hugh Bradner , in May 1983 eight of us left for two weeks together in Vava’u in the kingdom of Tonga. The group consisted of Margaret and Dave Mulliner, Jayne and Mike Anderson, Jane and George Robison, and Marge and Hugh Bradner. The Bradner s had gone ahead to make final arrangements for the trip. Four days later the rest of us arrived, late at night in Pago Pago, American Samoa. After going through customs, out contact lady, Manino met us. She had taxis arranged to take us to our hotel and told us, "There has been a slight problem, I will tell you about it at breakfast." At breakfast we learned that all of our plane reservations had been cancelled by the computers out of Hawaii. Fortunately, through the efforts of SPYC (South Pacific Yacht Charters) and Manino, our reservations were reinstated the next day and we were off. The first sight of Vava’u reminded us of the Tongan legend — "One of the Gods threw his net into the sea and dredged up many islands which he scattered over this section of the ocean and the result was the archipelago of Vava’u." Our first view was breathtaking. Islands, reefs, inlets, bays^ and fringing barrier reef clustered in a small area in the southwest Pacific covering no more than a fraction of a degree in latitude and a fraction of a degree in longitude. Tonga, South Pacific’s paradise kingdon, is remote from the normal tourist traf- fic. It is an archipelago south of the equator and west of the International Date- line. The explorer. Captain Cook, called them the "Friendly Islands," a phrase still synonymous with Tonga. Archaeologists claim Tonga has been inhabited since the 5th century B.C. The Islands have never been colonized and their present monarchy goes back over a thousand years. Tonga consists of three main coral and volcanic Island groups, one of which is Vava’u. It is a place of brilliant colors, white coral sand beaches, lush green coconut plantations, blue shallow lagoons and deep water drop-offs. Of the 169 islands only 36 are inhabited. The people are Polynesians whose economy is based on agriculture and fishing. Much of the success of our trip we owe to our good friend and guide, David McLean David came to Tonga with the Peace Corps to teach school. He stayed on and in time married a beautiful Tongan lady named Hainite. Tongan families live from the land and sea and David and his family are not an exception. We are all grateful to them for sharing the native Tongan customs in their beautiful land. David made all the arrangements for the boats and the use of a small tropical island. He showed us some of his favorite collecting areas and special reefs, known only to him. He even left his own skiff for us to use when he wasn’t there. With David’s direction our group was introduced to moments that are unforgettable. Our landing in Vava’u was on a dirt airstrip in the middle of a coconut plan- tation. Our lodgings were small cottages overlooking the beautiful Bay of Refuge. The plans were to snorkel, reef collect on low tides and SCUBA on deep drop-offs, coral reefs and on an old shipwreck. We also planned to camp for several days on an uninhabited island on the outer edge of the Vava’u archipelago. Vol. XVI'(2) 1984 THE FESTIVUS Page 12 Early the next morning we split up into two parties; one group going to a coral reef that stretches between two islands and encloses a lagoon, and the other going by car to a channel on the other side of Neiafu, capital city of Vava'u, for a snorkeling trip. For the first group, it was an hour’s ride in the small skiff to the reef. On the ocean side of the reef, sandy patches separated the many coral heads. Snorkeling along the reef, we collected shells in the sand and around the corals. Our finds included: Terehra dimidiata { Llnne , 1758), T. af finis Gray, 1834, Thalotia subangulata ^ease, 186]J, and Vasum turbineZtus Linne, 1758. On the reef, at low tide, we turned rocks and coral rubble. There were very few live corals because this reef is used by the local gill net fisher- men who break up and roll over any large corals that might damage their nets. Most of our shell finds were cones, cowries^ and some bivalves. We collected on the reef un- til the rising tide drove us inshore. Our finds included: Conus ebumeus Hwass, 1792, C. impevialis Linne, 1758, C. miles Linne, 1758, Cypraea oauriea Linne’, 1758, C. Humphrey sii Gray, 1825, C. isabella Linne', 1758 and, nearby, a melanistic C. mapp*a Linne", 1758 (Figure 1). During this time, the se- cond group was snorkeling in the channel on the other side of Neiafu. The current there is swift except at slack tide. ^ Figure 1. A melanistic Cypraea mappa. Many species of shells were found there in the sand and under dead corals. The best find of the day was a nudibranch, a Bornella, the species still undetermined. One of the highlights of the trip took place the next day when Jayne and Mike ex- changed wedding vows in a quiet amphitheatre framed by tall fern draped trees and shaded by fragrant frangipani. In the background sailboats rocked gently in Port of Refuge harbor and in the distance stood Mt . Talau (Figure 2). In typical Tongan fashion the wedding breakfast was held in a thatched roof, tapa decorated fale surrounded by an abun- dance of tropical foliage. Late that afternoon yachtsmen and tourists from several countries gathered for the Feast. We drank toasts of Kava from polished coconut shells and coconut milk laced with rum from , ^ ^ , Figure 2. Mike and Jayne Anderson large unhusked, fresh coconuts. The feast was cooked in an underground oven called an 'umu. ' We watched them remove the warm sand cover and layers of banana leaves until the top layer of food was exposed; steaming papaya with coconut cream in coconut shells, small tied packets of taro leaves containing fresh fish or chicken or Helaby’s lorned beef and finally Page 13 THE FESTIVUS Vol. XVI(2) 1984 the pig. All of this food plus lobster, fresh fruit, octopus, breadfruit, taro, and raw fish was artistically arranged on six foot trays of woven palm fronds. Our party had the place of honor at a table with benches and the rest of the guests sat on woven mats on the ground. There was music, singing, and dancing. We spent our days exploring and learning about the islands (Figure 3). Swallows Cave, at the edge of the the sea near Toula, was both forboding and beautiful. Erosion created the sealevel cave out of the high cliffs of coral and volcanic rock. We rowed into the cave, a jet black, huge hole in the side of a rock cliff with hundreds of swallows darting in every direction. Once the birds settled, a still- ness filled the immense, dark, cavernous space. The water in- side the cave is 40 feet deep; the roof is 30 feet high and filled with swallows' nests. Looking out to sea we could see the corals growing on the reef along the sunlit entrance. We also climbed Mt. Talou. According to reports, a well- Figure 3. A channel in the Vava'u archipelago, trimmed path would take us to the top of the highest point in Vava'u. However, we climbed and stumbled and cut our way through the thick jungle. It was worth it when we witnessed a panoramic view of the entire archipelago as it faded into the open sea. We were fortunate in being able to participate in welcoming the king to Neiafu and share the annual Red Cross banquet with the Queen. Natives provided bread- fruit, octopus, pork, fruit, and other native foods. Immense quantities of food were beautifully served. As soon as the dancing started, and met with the Queen's approval, the place went wild. We withdrew early with stuffed bellies and aching feet. We were up early for our camp- ing trip to a small uninhabited Island called Nuku. We checked our gear and supplies and stowed them aboard the Hine Moana (Goddess of the Deep Sea) . The Hine Moana (Figure 4), a 27 foot wooden launch owned by the Catholic church, is used on Sundays to carry ^oat, the Hine Moana. prxests to remote villages. David had made arrangements to charter this boat. By the time the six of us, David, the Captain and two crew members boarded^ the ship was quite low in the water and we chugged out of the Port of Refuge harbor. Vol. XVI'(2) 1984 THE FESTIVUS Page 14 Our excitement mounted when a small white island appeared on the horizon. Many different shades of blue water surrounded this palm- dotted Island. The beauty was almost impossible to believe. The first member of our group to set foot on the un- inhabited island was met by a Cypraea mappa Linne', 1758 curiously stranded in the pure white sand. While the crew members set up camp (Figure 5), by building a palm thatched shelter and digging a pit for cooking, the rest of us dis- persed to the reef or the sea. The snorkeling and diving were superb. A gentle sloping Figure 5. Our campsite on Nuku. bottom to 30 feet, gave way to small coral heads, slipper corals and two to three foot long Tridaona gigas Linne, 1758. A nearby cliff dropped radically to 100 feet where beautiful huge coral heads could be seen in the distance. The reef walkers, snorkelers, and divers displayed their finds which included: Hatioti-s ovina Gmelln, 1791, E. vavia Linne, 1758, Troahus triaatenatus Reeve, 1861, Conus arenatus Hwass, 1792, Cypraea aameola Linne", 1758 and Clavus aanioularis (Rodlng, 1798) (Figure 6). Native handcrafts such as tapa (bark cloth) , basketry and wood carving have changed little since the ancient days of the Kingdom. The soft sounds of wood against wood can still be heard in the villages as the paper mulberry (hiapo) stem is pounded into tapa cloth that serves as blankets, wall coverings, and ceremonial clothing. Traditional Tongan crafts are utilitarian articles of every day life and not presently made for export or tourism. The best way to acquire a marvelous basket, fan or ta'avala (a decorative girdle worn by both men and women as a sign of respect) is to smile, purchase, or trade for it. There are, t?- c. however, on the tiny island of Vava'u a igure . CZavus oanZouZar'is (Roding, 1798) small, quality gift store in the Paradise International Hotel and a Co-op store Page 15 THE FESTIVUS Vol. *XVI(2) 1984 infrequently open in Neiafu. An abundance of crafts can be discovered at the town market on Cruise Ship days or by attending local village feasts. The main island of Tonga, Tongatapu, has an excellent Cultural Center dedicated to the preservation of Tongan heritage. Demonstrations of tapa making, herbal medi- cine, basketry, and ceremonial rituals can be seen at the Center, and it is an excel- lent opportunity to learn about the Tongan way of life. Some nice wood carvings can also be found in Vava’u. Walking sticks, figures, masks, turtles and crabs are the most common. There are two master black coral carvers on the island, Leonati, who specializes in black coral whales and tiki gods and David McLean who creates Intricate necklaces and fish inlaid with abalone, ivory and shells. Port Maurelle, a small peaceful inlet bordered with palm trees that reflect on the crystal blue water, occupied both the novice and advanced snorkelers. We spent hours searching out the numerous terebra tracks and wondering about the existence of the three to four foot sea cucumbers that inhabit the area. The shallow water coral heads housed millions of brightly colored fish: clownfish, angelfish, and lionfish of various shapes and sizes. Among the shells collected here were: Murex brunneus Link, 1807, Cypraea Umaoina Lamarck, 1810, Conus marmoreus Linne', 1758, Terebra babyZonia Lamarck, 1822, OZiva oaeruZea Roding, 1798, Spondytus duaalis Roding, 1798, and Fimbria fimbriata (Linne, 1758). Our cliff dive off Swallows Cave was a favorite. The coral encrusted cliff drop- ped straight down to a depth of 80 feet. From the surface, a skin diver could easily see those exploring with SCUBA on the bottom. As we descended we saw many varieties of tropical fish along the cliff face and ledges and gorgonians (sea fans), coralsj and sponges on these ledges. One hundred feet above, the boat seemed suspended in sunlight . A second deep water dive was made in the inner harbor of the Bay of Refuge. A copra ship sank there 50 years ago when a fire continued to burn in her hold. The ship is upright on the bottom at 130 feet. We descended a buoy line to the top of the mast at 45 feet. Then we followed the coral, sponge and bivalve encrusted mast to the yardarm at 75 feet. The deck of the ship lay at 90 feet. We inspected the mast for gastropods, especially for Cypraea that might be at the base of the corals. We found only the bivalve Ostrea aristagatti Linne, 1758. The deck and railings were covered with a fine silt that became dense fog with the slightest disturbance of the water.^ W'e did not find any shells on the deck and it was with relief that we surfaced from this eerie graveyard of the deep. On the southern edge of the Vava’u group. Euakafa Island is surrounded by shal- low coral reefs that extend for several miles. The dam- age from Hurricane Isaac in 1982 was evident in the shal- low reef area. Here all of the coral heads were broken and dead. The hurricane rolled many of them down the slope. Only an occasional coral heiAd survived (Figure 7) and those were in slightly deeper water. Figure 7. Underwater view of hurricane damage at Euakafa Island. Vol. XVI(2) 1984 THE FESTIVUS Vol. XVI (2) 1984 As we descended the slope, live corals became more numerous until at 4J feet beauti- ful coral colonies were everywhere. Our shell finds here included: Cymati-um piteare (Linne', 1758) (Figure 8), Conus pulicarius Hwass, 1792, Terehra /e Z tna (Dillwyn, 1817/^, and Stromhus dentatus Linne", 1758 (Figure 9). A nearby reef produced many miters. In five to fifteen feet of water the follow- ing were found: Mitra Qovonata Lamarck, 1811, M.fZoridula (Sowerby, 1874), M. vuttuosa Reeve, 1845, . M. tuguhris Swainson, 1821, Yexittum paoifioum (Reeve, 1845)^ and Ptevyg-ia crenulata (Gmelin, 1791). Reef walking was also productive. Conus textile Linne, 1758, Mitra mitra Linne", 1758, Terebra maoulata Linne, 1758 as well as many cowries, rock shells and bivalves were found. Figure 8. Cymatium pileare (linne, 1758) Figure 9. Strombus dentatus Linne", 1758 Hurricane Isaac struck Vava’u with winds of more than 100 mph. , driving nearly all boats in the very well protected Neiafu Harbor onto shore near the upper end of the bay and severely damaging buildings throughout the archipelago. Hurricanes are even more devastating to undersea life than that on land because the immense waves generated by the storm can scour the bottom to more than 100 feet depth. The surging water can tear apart sturdy coral heads, tumble rocks as big as houses and completely destroy beautiful collecting areas for five years or more. We were interested in appraising the underwater damage resulting from the hurri- cane the previous year. We were very surprised. There were, indeed, regions that had been denuded ... scoured barren rock slab where a year earlier there had been live coral; many fish and mollusks and turnable rocks covered with multicolored sponge... but adjacent large regions seemed unaffected. In one area, everything except one large fragile looking coral head had been torn apart and left dead (Figure 7). David McLean remarked that his favorite cowrie bed had survived the hurricane only to be devastated by a Tongan family who moved every rock and collected every visible mollusk there during a week of low tides. Page 17 THE FESTIVUS Vol.- XVI (2) 1984 Another favorite cowrie area on an exposed reef flat was completely unaffected by the great storm. The sheer wall at Swallows Cave was not damaged and the sandy bottom at Port Maurelle seemed undisturbed. We observed that the hurricane did remarkably little damage to the undersea life of Vava'u. Having reached this conclusion we reexamined the nautical and bathy- metric charts of the region to see if they might explain the phenomena and perhaps aid in predicting effects of hurricanes elsewhere. We noted that the outer reef surrounding the archipelago might be an effective barrier for long period storm waves; while the many islands rising from the relatively deep lagoon might break up most of the surges that came across the outer reef from very large waves. The archi- pelago is so small that storm winds cannot regenerate large waves in the lagoon. The hydrodynamics and geography are so complex that we are unable to predict regions of low damage accurately, but our observations on Vava'u seem to follow from the above- mentioned considerations. On our last night in Vava'u, David McLean, in the style of Polynesian legends, touched and surprised us by giving each of us our own fish names and we left Tonga with our memories, crafts, and shells.

The tidal measurements, in this calendar prepared by the University of Arizona, are for Puerto Pehasco and are given in Mountain Standard Time. To correct for San Felipe, subtract one hour from listed times (San Felipe is on Pacific Standard Time). For Bahia de Los Angeles, add 15-30 minutes to calendar predictions (the amplitude at Bahia de Los Angeles is about one-half of calendar measurements). Tides at Santa Rosalia and Guaymas cannot be estimated using this calendar. [Interpretation of tide calendar curves is approximate].

Vol. XVI (2) 1984 THE FESTIVUS Page 20 EXAMINATION OF GARI HELENAE OLSSON, 1961 AND REDISCRIPTION OF THE HINGE/LIGAMENT BY BARBARA W. MYERS, JOYCE GEMMELL, CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In our continuing study of the bivalves from the Gemmell collection from San Felipe, Baja California, Mexico, we had difficulty identifying specimens in the genus Gari- (Family Psammobiidae) . It was necessary to borrow the type material for Gart- helenae Olsson, 1961, G. panamensis Olsson, 1961, and G. vegutav'is (Carpenter, 1864); three related species which resemble each other superficially. While the spe- cimens from the Gemmell collection appeared similar to these three species, the struc- ture of the hinge/ligament was different than was indicated in the descriptions of the aforementioned species. Examination of the type material of the three species revealed a hinge/ ligament in Gavi- helenae quite different from that of both G. panamensis and G. regutaris . The hinge of G. helenae contains a chondrophore and resilium, features lacking in G. panamensis and G. regularis. The Gemmell specimens show the chondrophore and resilium and, after study, we determined that the specimens in the Gemmell collection are G. helenae. The type of Gari helenae, from the Academy of Natural Sciences of Philadelphia (ANSP 282395), is a pair measuring 52 x 27.3 mm from the Pearl Islands, Panama (Figures 1 & 2) . Fig. 1.

The Gemmell specimens (Lot #G453A) , 83 valves (38 left valves, 45 right valves) from 3 mm to 6 mm in length were found to be Tetlina hihevna. They were collected intertidally at Playa Alicia, 40 km (approximately 25 miles) south of San Felipe, Baja California Norte, Mexico at a -1.8 m (-6 ft) low tide on March 28, 1975. The type of Tellina amianta Dali, 1900, a pair, was borrowed from the National Museum of Natural History, Smithsonian Institution (USNM #108560). It is shown here in Figures 11 and 12. The measurements are 12.5 mmL x 6.2 mmW x 3.5 mmD. The original description is reproduced below. TELLINA (MOERELLA) AMIANTA new species. (Plate III, fig. 12.)

The left valve of the type of T. amianta is shown in Figure 13 in camera lucida drawings. The species has a rather straight ventral margin with a straight, pointed posterior slope. The concentric sculpture of T. amianta, under magnification (Figure 14) appears as raised cords that sometimes become raised lamellae at the posterior slope.

Vol. XVI(3) 1984 The type locality of this species was given as Cape Tepoca near the head of the Gulf of California. Bernard (1983:42) lists the distribution as 2°S (Ecuador) to 31°N (San Felipe) including the Galapagos Islands. Gemmell specimens of T. amianta (hot G452S) were taken from seastar stomachs off Punta San Felipe (Gemmell, Hertz, Myers 1980) . Lot G452 of 23 valves (8 left valves and 15 right valves from 6 mm to 8.5 mm in length was was taken intertidally at Fig- 15. Camera lucida drawings (reduced) of the Playa Alicia, south of San dentition in Teltina ami-anta. Felipe, Baja California Norte, and was also found to be Tetlina amianta. The differences in the dentition between T. hibeima and T. amianta are negligible and not a useful character for Identification. The two species overlap geographi- cally throughout most of their range. When juvenile, the two species are so nearly alike that it is difficult to distinguish one from the other. The adults of T. hibevna and T. amianta show differences in external sculpture under magnification; the sculpture of T. hibema appearing as flattened layers and that of T. amianta as raised cords sometimes becoming raised lamellae at the posterior slope. See Figures 6 and 14. The ventral margin of T. amianta is rather straight while the ventral margin of T. hibema is widely curved. See Figures 13 and 5. In T. hibema the posterior margin is highly flexuous (Figure 2) and the posterior slope in T. amianta is straight (Figure 11).

Box 1390, San Diego, California 92112 During the January low tides, Jules Hertz and I observed an abundance of Bulla gouldiana Pilsbry, 1893 both in Mission Bay, San Diego and on the open coast near Cardiff, California. On January 17, on a -1.8 ft. low tide at 3:05 P.M., at Sea Cliff Roadside Beach in Cardiff, hundreds of small (^ 17 mm) Bulla gouldiana were seen tracking and emerging from the packed sand at the water's edge and moving about on the large boulders in the shallow water. The following day, January 18, we went to Ventura Cove and Crown Point, two areas in Mission Bay, San Diego. At these locations, during a -2.0 ft. low tide, it was almost impossible to walk in the low tide area without stepping on B. gouldiana of all sizes as they were emerging from the muddy sand. Both these areas have large quantities of the eel grass, Zostera. It seemed that every blade of the grass was overburdened with the orange-bodied "bubbles." Also observed at these two locales in Mission Bay were quantities of large Navanax inermis (Cooper, 1862). Egg masses of N. inermis were also noted. Marcus (1961) in Opisthobranch Mollusks from California, Veliger 3 (Supplement), cites C.E. and Nettie MacCinitie observing N. inermis feeding on Bulla and Haminoea as well as on small members of their own species. Vol. XVI(3) 1984 THE FESTIVUS Page 35 AIM IMPORTANT NEW CHITON PUBLICATION BY GEORGE HANSELMAN Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P,0. Box 1390, San Diego, California 92112 A recent chiton publication, "The Systematic Classification of the Chitons (Mollusca: Polyplacophora) , " by Richard A. Van Belle, has been issued by the Societe Beige de Malacologie of Brussels, Belgium, as their Informations, Serie 11, No. 1-3, April 1983, editor R. Duchamps, Avenue Mozart, 52, 1190 Bruxelles, Belgium. It is a well-printed paper-covered volume of 179 pages, including 13 plates. The publication is essentially in three parts. The Introduction notes that establishment of major taxonomic elements down through the generic level is con- sidered best determined by analysis of the structure of the articulamentum, or inner portion, with all other characters limited to a secondary or supplementary role. Inasmuch as the intent of the paper is to cover Fossil as well as Recent species, this seems reasonable; in practically all instances of the recovery of fossil chiton remains a portion of the articulamentum is all that is left. As to Recent species, the idea of relegating the far more obvious and complex external characters to a secondary function appears somewhat drastic; however considering the sad condition of most "mummified" museum specimens, whose dessicated remains furnish the basic source material for most studies, this reasoning may still be deemed valid. The second and especially valuable portion is an historical tabulation of major chiton papers, from Linnaeus, 1758, up to date. It is highly informative to have all these summaries side by side and be able easily to review and compare the continuing steps in the development of taxonomic structure. Part three is a suggested systematization of currently known chiton groups. Fossil and Recent, down through the Genus level. Each major level is annotated with author, date and vehicle of publication, pertinent synonymy, the original description and where pertinent a brief additional comment. For Genus and Subgenus the preceding information is given, plus the type species, its author and date, and its principal synonymy. The thirteen black-and-white plates present generally adequate ink or photo depictions of 106 type species. As a result the paper is an invaluable refer- ence source. It should also be noted that this paper was recently preceded by "Catalogue of the Living Chitons," by Kaas and Van Belle, 1980, a comprehensive listing of Recent species citing original nomenclature, author, date and vehicle of original publi- cation, type locality, current nomenclature, and principal synonymy needless to say in itself another valuable reference tool. Additionally, a further series of papers is in process by co-authors Kaas and Van Belle, to comprise together a "Monograph of Living Chitons." It therefore ap- pears that a competent replacement for Pilsbry's master chiton study (Volumes XIV and XV, 1892 and 1893, of the justly famous and now unobtainable Tryon "Manual of Conchology") may finally be forthcoming. Certainly the two papers noted here plus the upcoming monograph will be MUST items on the list of any serious student of the Polyplacophora. Page 36 THE FESTIVUS Vol. XVI(3) 1984 SUMMARY OF LAWS AND REGULATIONS RELATING TO SHELL COLLECTING IN SOUTHERN CALIFORNIA AND MEXICO (as of Feb. 198A) COMPILED BY BILL PERRIN 2947 Luna Avenue, San Diego, California 92117 CALIFORNIA You must have a sportfishing license ($8.50) to collect (fish for) anything anywhere in California. There is a general prohibition on the taking of marine inver- tebrates within a zone extending from high tide mark (mean higher high tide) to 1000 feet seaward of the low tide mark (mean lower low) with the following exceptions: A. In State parks, beaches, recreation areas, underwater parks and reserves and in National parks, monuments and seashores, you may take abalones, clams (all species), rock scallops, crabs (and whatever they're living in), lobsters, ghost shrimp and sea urchins . B. In other areas, except where prohibited in marine refuges or other special marine reserves (for example, the La Jolla Marine Reserve, where not even dead shells may be collected), one may take the above-listed plus limpets (all species), moon snails, turban snails {Tegula spp.), mussels, octopus, and squid, shrimp, sand dollars and worms. ALL OTHER SPECIES ARE PROTECTED within the 1000 ft zone (e.g. cowries, cones, murexes, mud snails, wavy tops, speckled scallops, etc.). Beyond the 1000 ft limit, any invertebrates (except speckled scallops) can be collected, but the bag limits and size limits (listed below) must be observed. Invertebrates can be taken only by hand (shovels can be used for clams) or by hook and line. You must have a measuring device with you when you are collecting some- thing that has a size limit. Dredging is Illegal in all areas, except under a scien- tific collecting permit. Any collecting under a scientific permit ($5-10/year) must be for the sponsoring institution (museum, university, etc.) and must be reviewed for po- tential environmental impact (by the local office of Cal. Fish & Game) and approved in advance by the Marine Patrol Inspector in Long Beach. Within National parks, monuments, etc., approved scientific collecting may be done with a Federal permit obtained from the Superintendent (no State permit is required). However, the conditions and limitations on such collecting are currently being streng- thened . BAG AND SIZE LIMITS Abalones {Ealiotis spp.) - limit 4 in combination, in season Red {E. rufesoens) - 1 inches Green ^E. fulgens) ^ pink {E. corrugata) and white (E. sorenseni) - 6 inches Black {E. araaherodii) and others - 4 inches Clams : Gapers {Tresus nuttaltii) - limit 10 Washington {Saxidomus nuttallii) - limit 10 Geoduck (Panopaea generosa) - limit 3 Littleneck (Protothaoa spp.), soft-shell (Mya arenaria) , chiones (Chione spp.), northern quahogs (Meroenaria meraenaria) 3 and cockles {Tvaohyaardiim quadragenariiMTis Laevioavdiim elatum & Clinocardiim nuttallii) - limit 50 in combination, size limit 1.5 inches Pismo {Tivela stultorum) - limit 10; 5 inches Razor (Solen spp., Siliqua patula & Tagelus oalifomianus) - limit 20 Other clams - limit 35; no size limit Mussels (Mytilus spp. - limit 25 lbs Rock scallops (Einnites giganteus) -limit 10 Vol. XVI(3) 1984 THE FESTIVUS Page 37 Squid - no limit Moon snails iPo'i'Lnioes spp. ) - limit 5 Other mollusks - limit 35 Crabs : Dungeness (Cancer magister) - limit 10 Rock crabs (other Cancer spp.) - limit 35; 4 inches Hermit crabs - limit 35 Bay shrimp - limit 5 lbs. Ghost shrimp and blue mud shrimp - limit 50 Spiny lobsters - limit 7; 3.25 inches (carapace); in season Other invertebrates - limit 35 MEXICO Shell collecting per se is prohibited in Mexico except under a scientific permit, which can be obtained from the Mexican Department of Fisheries (Departamento de Pesca) . With a Mexican fishing license ($14 per visit, under current interpretation), the fol- lowing can be taken for immediate human consumption: clams, other than pismos (bag limit 20/day) ; other mollusks, other than oysters and abalones (limit 20/day except 10/day for scallops); crustaceans, other than lobsters and shrimps (limit 10/day). Abalones, pismo clams, oysters, shrimp and lobsters may not be taken under any circumstances. Use of nets, traps or dredges is prohibited. No fishing (including invertebrates) is allowed in ecological reserves. These include Laguna Ojo de Liebre (Scammon’s Lagoon) and Laguna San Ignacio. Fossils may not be collected in Mexico. The laws of both California and Mexico prohibit the sale or trade of anything taken with a sportfishing license. IF IN DOUBT, CHECK IT OUT! John Duffy Calif. Dept.

After the Introduction of guests, Richard Herrmann introduced the guest speaker for the evening. Viola Perrault’s program, ”5 Fathoms Down" Included scuba diving in the waters off the Maidive Islands. The information and underwater photographs of this remote area were very interesting. A most informative mini-program was presented by Bill Perrin on the laws and regulations relating to shell collecting in Southern California and Mexico. Bill supplied a handout sheet summarizing these regulations. (See this issue). The minutes of the January meeting were approved as printed in the February Festivus . June and Bob King have offered to hold the April 7th potluck/auction at their home. Shell donations for the auction can be given to any Board member or taken to Wally Robertson at London Associates, 1137 Prospect St., La Jolla; Richard Herrmann at New England Divers; Marine Invertebrate Department of the San Diego Natural History Museum. Everyone attending the auction is asked to bring a food dish for the potluck supper. Sign up as soon as possible. Our President attended the Feb. 9th meeting of the Botanical Foundation as re- quested by the Foundation. The new Balboa Park Plan proposed by the City would re- locate the Botanical Garden Foundation and its participating Clubs to the old Naval Hospital and take over the use of the Casa Del Prado. Further meetings are planned to protest this relocation. The delicious refreshments were donated by Harriet King and Billee Dilworth. FOR YOUR INFORMATION The 17th Annual Meeting of the Western Society of Malacologists will be held at the University of California at Santa Cruz on 16-19 August 1984. Emphasis of this year's meeting will be on the Natural History of Marine Mollusks of the Eastern Pacific Ocean. In addition to the regular program of contributed papers, several symposia are planned plus slide shows, exhibits, shell and book auction, and field trips. For further information contact Dr. F.G. Hochberg, Secretary, Department of Invertebrate Zoology, Santa Barbara Museum of Natural History, 2559 Puesta del Sol Road, Santa Barbara, GA 93105.

HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 At about 3:00 P.M. on January 1 of this year, Jules and I took a walk on the beach at Crown Point in Mission Bay, San Diego to celebrate the New Year and the -1.2 foot low tide. We had slogged through the low tide mud from one end of "Ski Beach" to the other and were turning around for the return stroll on the higher and drier packed sand when I spotted something shell- like on an isolated patch of eel grass (Zostera) in the high mid- tide zone. I was astounded to find a Simnia on the sand in the Bay ! We thought it was dead but put it in a vial with water to keep it from breaking as it rolled around in the bucket. It wasn't until Figure 1. Simnia barbarensis (Dali, 1892) in we reached home that we observed studio aquarium setup. Photo: Mulliner the "dead" shell moving with its animal fully extended. Figures 1 and 2 are pictures of the live animal taken in a studio setup on preserved gorgonian by David K. Mulliner. The animal lived for over three weeks in a two quart cas- serole dish with the water changed daily. The animal of this Simnia is striking. The color of the animal varies from a creamy white to pale rosy- beige on parts of the head and foot with the mantle and edges of the foot having the ground color of rosy beige peppered with randomly placed and irregu- larly shaped black spots. On color slides of the animal, also taken by Dave Mulliner, bright white papillae can be seen Figure 2. Same animal as shown in Figure 1. Photo: Mulliner Vol. XV(4) 1984 THE FESTIVUS Page 42 among the black spots. These papillae were not visible to me whan I studied the live animal under a hand lens. The upper portion of the posterior of the foot shows a V-pattern in which the color grades from orange to orange-black. The color of the head changes from cream at the base, to beige, to brown, and then to black at the outer edge near the mouth. The antennae are white-tipped, centrally orange and dark rust and white at the base. The eye stalk is white with a large black eye. Figures 3 and 4 of the dorsal and apertural aspects of the shell were taken after the animal was preserved. The translucent shell, which measures 28 mm in length, has a pinkish cast exteriorly with orange pointed terminals. The glossy dorsum is smooth except for growth lines and rows of fine transverse striae which are re- stricted to both ends. The dorsum is inflated with the columella (fossula area) convexly curved. There is hardly the appearance of a funiculum. The outer lip edge is edentate, slightly thickened and white. Figure 3. Dorsal view of shell of Sirmia havharensis . Loyal J. Bibbey suggested the Identification of this species as S'tmri'ia barbarensi-s (Dali, 1892), an identification with which I concur. Figure 5 is the type of S. barbarensis from Dali (1892). It was originally named as a "variety" of Ovuta (Sirmia) deflexa Sowerby, which Dali said was a southern form of S. barbarensis. The type was named from a single specimen "one inch in length, found in San Pedro Bay, by Miss Monks." Cate (1973) stated that the Monks collection was "now presumed to have been broken up and scattered and the type lost (Elsie Chace, Los Angeles).'' In the same paper Cate chose a neotype (CAS 32437) which is shown here (from Cate) in Figure 6. The neotype measures 31.8 mm in length. Cate gives the "distributions" of this species as "73-125 m, San Pedro Bay; 91 m, off Avalon, Santa Catalina Island; Santa Barbara; Morro Bay (?), California." Figure 4. Apertural view of specimen shown in Figure 3. Photos: Mulliner Page 43 THE FESTIVUS Vol. XV (4) 1984 S'imri'ia barbarensi-s is usually found in deep water on the open coast. Two other specimens of this species in our collection (previously misidentif led) were trawled in 100 fathoms off La Jolla, California. Two lots in the San Diego Natural History Museum collections are labeled S. barbarensis. Lot SDNHM 57426 contains 5 juvenile specimens from San Pedro. The specimens are extremely worn. 1 could only note determining characters on one specimen. Lot SDNHM 56512 is one specimen trawled in 50-55 fathoms off the mouth of Monterey Bay. Since Sirmia feed on gorgonians, they are not usually found intertidally , and to find a live one beached in Mission Bay is a most unusual occurrence — and a mystery! U. S. NATIONAL MUSEUM Figure 5.

Yokes 1983 Mesoamerican Ecology Institute Monograph 1, Middle American Research Institute, Tulane University, New Orleans Publication 54. 182 pp. , 50 pis. Price: $21.50. This is an illustrated checklist of 769 species found in the shallow waters off the Yucatan Peninsula. This systematic list of species follows Abbott's AMERICAN SEASHELLS (1974) to which the authors refer you for further information. Each of the 769 species is illustrated in 50 black and white plates. The illustrations are clearly defined and will be useful for identification. Often a holotype or lectotype of a species is shown. Plates 23-31 and Plate 48 are devoted to micromollusca; those often ignored or overlooked groups in other works. The Yucatan Peninsula projects from mainland Mexico into the waters of the Gulf of Mexico partially inclosing the Gulf at its opening into the Garibbean Sea. The north and west coasts of the peninsula, therefore, are bordered by the Gulf; the east coast by the Garibbean. The coastal perimeter of the peninsula was divided into seven areas and each area was subdivided into an unequal number of collecting sites. Four areas were located on the Gulf side, one area at the transition zone (between the Gulf and the Caribbean), one area in the Caribbean and one area that included offshore sites in both the Gulf and the Caribbean. There was no indication to what depth the collecting was made or if it was strictly intertidal, though there was a note that much of the material was beach collected. Appendix 1 lists frequency of occurrence of each species according to area, but no Information was given for species according to sites within areas. This study was begun by Dr. E. Wyllys Andrews and was continued after his untimely death by the Drs. Yokes. It represents years of field work since the Yucatan coast, by my quick estimate, covers well over 500 miles and many of the sites were remote and accessible only by boat. This work should prove to be very useful for workers interested in the Gulf of Mexico and Garibbean molluscan fauna. Our Club library has purchased this publication and we expect it will be avail- able for circulation in July. Page 45 THE FESTIVUS Vol. XV(4) 1984 A COLLECTING TRIP TO BAHIA SAN LUIS G0NZA6A. BAJA CALIFORNIA NORTE. MEXICO BY DAVID K. MULLINER and GALE G. SPHON Department of Marine Invertebrates, San Diego Natural History Museum, P.O. Box 1390, San Diego, CA 92112 The lowest tides of the year in the Gulf of California were during the week of February 12-18, 1984. Gale Sphon and Dave Mulliner headed south along Mexico's Highway 1 to El Crucero, south of Laguna Chapala, and took the dirt road 47 miles northeast to Bahia San Luis Gonzaga (Gonzaga Bay). There is one five mile long sand filled arroyo that gets softer as you travel down the arroyo. It is best not to attempt this road in a camper. A better and graded road starts north of Laguna Chapala and goes to Gonzaga Bay. It is 40 miles to the Bay and can be driven in any vehicle that has high clearance. This is the road we returned on. Between Punta Final and Punta Willard in the northern Gulf of California, lies a crescent- shaped bay. See map in Figure 1. Isla Willard lies just offshore and at the northern end of a long sand spit. At low tide you can walk to the island. The collecting areas are a large mud flat to the north of Willard Island in Willard Bay and a sand flat to the south in Gonzaga Bay. There are turnable rocks on Isla Willard both to the north and south of the sand spit. Collecting was done on all six low tides. The evening tides were the lowest and only on the last two was it necessary to carry a lantern. Twenty-seven species of gastropods and bivalves were collected: only four of these were abundant. Six species of chitons were found and Department of Malacology, Los Angeles County Museum of Natural History 900 Exposition Boulevard, Los Angeles, CA 90007 area. This map is not to scale. Vol. XV (4) 1984 THE FESTIVUS Page 46 only five species of nudibranchs. See list below. We also dredged and this material was taken by Gale Sphon to the Los Angeles County Museum of Natural History for study. However, a superficial appraisal study of this material showed no mollusks. We compared our list of 38 species collected with the checklist for Bahia Willard published by DuShane and Sphon (1967) in which they reported 310 species of mollusks. (They did not include nudibranchs). We could see no apparent reason for the scarcity of mollusks in this area. There is very little collecting being done by natives or tourists. The one small fishing village and tourist cabins (mostly "fly-in" people) could not possibly pollute this large bay which is eight miles long from Punta Final at the southern end to Punta Willard at the north. The occurrence of the "El Nino" is the only reason we could think of for the poor collecting. The water was about 8^ F warmer than one would expect for this time of year (Robinson 1973). The scarcity of algae, even sargassum, which is usually abundant in this area, indicates very little, if any, upwelling; the lack of which is one of the effects of the El Nino.

MYERS Extensive coral gardens, colorful exotic fish, deadly sea snakes and the ever fearsome shark were all displayed in the marvelous slide show of Phil and Heidrun Faulconer. The program was so well edited it made you feel you were there swimming in the warm clear waters of the Great Barrier Reef and the Coral Sea. The mini-lecture this month was "Cones" given by Martin Schuler. Marty prepared an explanatory handout for those attending and discussed shell characters used for identification as well as giving a detailed explanation of the venom process. The business meeting started with an acknowledgment of the donation of the Morris Levine Library. Most of the books had been catalogued into our Club library and were on display ready for circulation. Nola Michel made a motion, seconded by Bill Perrin to accept the minutes of the February meeting as they appeared in The Festlvus. President Jules Hertz attended the Botanical Garden Foundation meeting March 8th. The Foundation is circulating a petition to protest the removal of the occupants of the Casa Del Prado and the closure of the vehicular access of Village Place. (The existence of the Casa Del Prado is due, in large part, to the efforts of the Botanical Garden Foundation). A copy of the petition was available for members' signatures. David Mulliner showed pictures taken at the Christmas Party. The Auction was discussed. Everyone was reminded to donate specimen shells. If you haven't paid your dues by March 31st, your name will not appear on the membership roster. The cookies for this meeting were donated by Rose and Anthony D'Attllio and Heidrun and Phil Faulconer. THE ANNUAL AUCTION/POTLUCK The Club's Auction, graciously hosted by June and Bob King, was a riproaring success. Members and their guests bulged the walls of the Kings' beautiful home. There was Dave's marvelous brew served on the patio, all sorts of special foods pre- pared for the potluck dinner, and the comaraderie of friends getting together. Jules Hertz announced the start of the auction at about 8 P.M. and members were enthusiastically responsive to the three auctioneers j Carole Hertz, Marty Schuler, and Dave Mulliner. Bidding was spirited, the shells for auction- choice, and the evening a social and financial success. Our gratitude to our hosts and to those who worked to make the occasion successful — the preparers, the donors, and the bidders. ■ >(0! i,i '5^' *'■■ ■ 'i I "" J ' **' % "4 , .J'^ ' t- f :r^~>^j\!i ' yi'’ '■■ .V ■ '/ 'f l^v I-:.; i y'v ';' , U;. y'fe •c,: ■'{ ■•■.■■'■’if) \-ma^. •• 'S'A ■ ■ mv(# Siltn 44^'^ 'V' ivJti , ' ■ .f. 4^i iiff :?v' ' ■ , y''; ■■" H < . f:fi: ',.

HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 Among recent donations to the San Diego Natural History Museum, from Mr. Donald Pisor of San Diego, were two "live collected" specimens of Tripterotyphis towei coZeman-i (Ponder, 1972). See Figures 1 and 2. These, with other examples of this species which were shown to us, were collected "from under rock slabs at low tide, entrance to Point Broome." They were collected there by Kerry and Barry Sharpe and were brought from West Australia by Mr. Pisor. Tripterotyphis lowei oolemani. Fig* 2. apertural view. SDNHM 82096 Length: 10.5 mm. Donor: D.

SDNHM 23178 Length: 14.75 mm, Max. width: 9.25 mm Locality: Isla Tres Mujeres, Mexico Tripterotyphis lowei oolemani is barely distinguishable on shell characters from the eastern Pacific T. lowei lowei (Figures 3 & 4), a conclusion also reached by Ponder (1972). In his comments on the discovery of T. lowei oolemani at Queensland, he stated, "...If it were not for the fact that lowei is a Central west American species, the Queens- land form would hardly be worthy of separation." Figure 5 from Ponder 1972 illustrates Pterotyphis (Tripterotyphis) lowei oolemani from Tryon Island, Southern Queensland, Australia. We believe that the specimens from Broome (Figures 1 & 2) are nonspecific with T. lowei oolemani and extend the distribution of this subspecies from Queensland to the Indian Ocean. Anatomical studies may help to determine whether T. lowei oolemani is a valid subspecies or if T. lowei is a wide-ranging species. Examples of nominal subspecies of the Panamic T. lowei are found not only in the Queensland and Broome areas, but from Norfolk Island (Figure 6), The following list cites the localities from which T. lowei and its nominal subspecies have been collected.

ADAMS. 1852) BIVALVIA: TELLINIDAE BY JOYCE GEMMELL, BARBARA W. MYERS, CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 ABSTRACT Our study revealed that Maaoma siliqua (C.B, Adams, 1852) differs significantly from M. panamensis Dali, 1900 and M. panamensis speatri Hertlein and Strong, 1949 and that Thraaia aarmea Mo’rch, 1860 is a junior synonym of M. siliqua. We had in- sufficient study material to determine if M. panamensis speatri is a valid subspecies or a synonym of M. panamensis. In attempting to identify specimens of Maaoma sitiqua (C.B. Adams, 1852) in the Gemmell collection from San Felipe, Baja California, Mexico, we found con- flicting information in the literature. Keen (1971:229) considered M. panamensis Dali, 1900 and Thraaia aamea Morch, 1860 synonyms of M. sitiqua. Hertlein and Strong (1949) named M, panamensis speatri considering it a subspecies of Dali's M, panamensis. Keen (1971) considered it a subspecies of M. siliqua. In examining the Gemmell specimens and Museum specimens, we found that we had more than one species. Typological material was then borrowed. Type material of Maaoma panamensis Dali, 1900, M. panamensis speatri Hertlein and Strong, 1949, M. sitiqua (G.B. Adams, 1852), and Thraaia aarnea Morch, 1860 were examined. Maaoma sitiqua (G.B.

[Upper two figures = M. sitiqua, lower figure = M. panamensiS' Dalll The holotype of M. sitiqua (MGZ 186301), a pair, 21mm x 12mm from Panama is a glossy white, very thin, convex shell with minute concentric striae. Figures 1 and 2 are photographs of the type of M. sitiqua. It is truncate and gaping posteriorly with a strong posterior flexure. The beaks are at the posterior one-third of the shell. The concentric striae change direction on the angulate posterior of the shell. The pallial sinus is large and confluent for most of its length with the pallial line. In the right valve, the blade-like posterior cardinal tooth is broken and the anterior cardinal is peg-like. There are no laterals. Figure 3 is a camera lucida drawing of the dentition of the holotype of M. sitiqua. The cross hatching in the view of the right valve indicates that the teeth are broken and only the bases of both teeth are visible. The original description of M. sitiqua follows.

Lot G-445 containing four pair and 18 valves from 12 mm to 18 mm in length, are nonspecific with M. siliqua. They were collected in drift in the San Felipe Bay area. Figure 4, a Gemmell specimen, illustrates the posterior flexure in M. siHqua. Of the Gemmell specimens, 12 valves have the teeth unbroken. Four pair were closed and we were unable to study the teeth. Based on the study of the type material and the specimens in the Gemmell collection, we find that the dentition in this species is unusual. The heavy peg-like cardinals are anterior in both valves. The posterior cardinals in both valves are smaller and thinner. There are no laterals. A specimen of M. siliqua in the San Diego Natural History Museum collection (SDNHM 18918) shown here in Figure 5, further illustrates the dentition in this species with the large peg-like cardinal anterior in both valves. Examination of the holotype of Thraaia oavnea Mdrch, 1860, a Maooma, re- veals a very worn, moderately convex left valve with a hole in it (Figures 6 and l). All indications of interior and exterior sculpture have been eroded. The translucent sienna color as though it had from the substrate. This valve shows a prominent posterior angulation and truncation. Morch described the valve as "pellucens carnea vel sordide rosea." Only the anterior peg-like cardinal is visible.

Camera lucida drawing of dentition of panamensis speatri. Left valve (holotype), ght valve (paratype) The shell here described as a new subspe- cies is similar to that of Macoma panamensis, but it is higher in proportion to the length and so far as known it is generally restricted to a more northern range. Some young speci- mens are very similar to Dali’s species and perhaps additional specimens may show the form here described as new to be without significance, but the greater height, irides- cent color and generally more northern dis- tribution appear, at the present time, to be sufficient reasons for separating it as a dis- tinct subspecies. mViic now <;iibsner.ies is very similar to Macoma panamensis canaJis Olsson,'''' de- scribed from the Miocene Gatun beds of Panama, which also is higher in proportion to the length as compared to M. panamensis. The shell of the present subspecies is higher and a little less elongate than Olsson’s sub- species. Furthermore adult shells are mod- erately thick whereas those of Olsson’s sub- species were described as very thin and fragile. Page 60 THE FESTIVUS Vol. XVI(5): 1984 Fig. 13.

Mulliner Vol. XVI (5): 1984 THE FESTIVUS Page 61 It is our conclusion that Maaoma siliqua differs significantly from both M. panamensis and M. pancmensis speotri and Thvaaia oamea is a synonym of M. sitiqua. M. siliqua is a much smaller, more convex and fragile shell than M. panamensis. M. sitiqua has a pronounced posterior truncation while M. panamensis has the posterior end attenuated. In M. sitiqua the large cardinal in each valve is situated anteriorly. The posterior cardinal in each valve is small and thin. There are no laterals. In the holotype of M. panamensis (a left valve) there is a bifid anterior cardinal and a broken blade-like posterior cardinal and no laterals. We were unable to determine the dentition in the right valve. M. panamensis speotri hss a larger, heavier and somewhat more inflated shell than M. sitiqua with a more rounded posterior truncation. In M. panamensis spectri the large cardinal is anterior in the left valve and posterior in the right valve. There is a small, thin cardinal posteriorly in the left valve and anteriorly in the right valve. There are no laterals. This dentition differs significantly from M. sitiqua which consistently shows the large cardinal anteriorly in both valves. We studied one lot of M. sitiqua in the San Diego Natural History Museum col- lection (SDNHM 18918) of six specimens from San Felipe, Baja California collected by H.N. Lowe in 1935 from ten fathoms, and one lot from the Santa Barbara Museum of Natural History (SMBNH 16436) from San Felipe collected by Faye B. Howard in April 1957. Other lots in both museums labelled M. sitiqua were found to be M. panamensis spectri. We found no material that conformed to the description of M. panamensis. Our study material was insufficient to determine if M. panamensis spectri is a valid subspecies or a synonym of M. panamensis. Much more study material would have to be examined before we could comment on the distribution of M. sitiqua.

"The Western Society of Malacologists is about to embark on an experiment that will add a new dimension to the Society in particular, and to the entire field of malacological research in general. This experiment, for want of a better name, will be referred to as PROJECT DATA LOG. The purpose of this project will be to act as a clearing house for the input and compilation of information on selected topics in malacology. Topics may be as varied as malacology is itself, and will consist of a clearly defined area of malacological interest that is suitable for development of a contributory data base. The Society will act as the depository of collected data with the intent of publishing such compilations in its Annual Report, or as individual Occasional Papers. The purpose of Project Data Log is to elicit types of malacologi- cal data that are unlikely ever to be published by themselves in any other form, but which together will provide a significant resource for malacological research. 'Suitable topics for compilation in Project Data Log are endless, and could, for example, consist of geographic range extensions, new ecological and bathymetric re- cords, bibliographic compilations, and so on. A single topic will be selected every year, to be chosen by the incoming President or by Society members at its Annual Meeting. A committee of several malacologists appointed by the President will take responsibility for gathering, reviewing and confirming data records, compiling pre- liminary lists for Society and/or external review, and final editing and preparation of copy for publication. "Following informal discussions with several Society members, the first Data Log project was chosen to be a compilation of spawning records of West American gastropods associated with egg masses, or actually in the process of depositing egg capsules. Because of the rarity of these observations, we usually make special note of them and photograph the scene as well. However, most of these records remain unpublished and unavailable as a source of malacological data. Project Data Log will attempt to correct this gap in our knowledge of gastropod spawning records. Special data sheets for the submission of desired information are being prepared and soon will be avail- able. ..." IN NEMORIAh S.

FARMER 11061 Lea Terrace Drive, Santee, California 92071 On a trip to Baja California^ I stop- ped by San Quint in late in the day of December 23, 1983. Due west of Pedregal, a cinder cone, by the beach at San Quintin Bay, I found a stone fire ring in which were shells of edible species of mollusks. There were abalone shells, oyster shells, and pismo clams. One of the valves of the oyster shells found at this site still had a piece of adductor muscle attached to it. The impressive oysters were extra large. One valve is 11 inches long and 4 inches wide and another 9 inches long and 5 inches wide (Figure 1) . One has purple lines exteriorly. These oyster shells belong to the genus Crassostrea Sacco, 1887. They are large-sized oysters with the internal margins smooth and the adductor scars usually purple (Olsson 1961) . I looked at the collection in the San Diego Natural History Museum's Marine Invertebrate Department and the species Crassostrea gigas appears near to the identity of the specimens I found. For a figure of C. gigas ^ see Rice 1971:74. A check of the literature revealed two introduced species of Crassostrea in California; C. gigas (Thunberg, 1793) and C. virginioa (Gmelln, 1791) (Hertlein 1959). Hertlein (1951) named Ostrea Figure 1. Crassostrea valves found at Qorteziensis^ a Crassostrea , from Kino San Quintin Bay. Bay. However, no Crassostrea have been reported from the locality in San Quintin Bay^ though mariculture is evident there. The valves found at San Quintin Bay have been donated to the San Diego Natural History Museum. Literature Cited HERTLEIN, LEO GEORGE 1951.

HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 During the spring low tides in March of this year, we spent five days in La Paz, Baja California, Mexico relaxing and collecting on the afternoon low tides. We had not been to La Paz since 1970 when we'd vacationed there with our family. We found that the city had grown considerably — but gracefully. Though there are more restau- rants, hotels and "curio" shops. La Paz is still not a tourist town. This major port city manages to retain an atmosphere of serenity; it is still friendly, very clean, and lovely. We stayed again at the Los Arcos hotel which has undergone a sharp change from a quaint Mexican hotel to a three story cement structure. Though it has lost much of its charm in the transformation, it is still comfortable, convenient, and clean. We would stay there again. We spent some time on the commercial pier watching the relaunching of large mar- ker buoys and the unloading (and scrubdown) of the shrimp boats. Young boys dashed on the boats during the cleanup and salvaged small crabs (some Planipes pZeuvonoodes) and other small bait items. We noticed one boy with a Cassis centiquadrata (Valenciennes, 1832) and a large seastar recently snatched from the deck of a shrimp boat. Most amazing was watching the boys fish with nylon line and sparkplug weight through holes in the pier. The fishing was terrific. They'd hardly get the lines down before they were pulling up fish five or six inches long. The dumping of the fishing trash from the boats probably attracts the fish to this area. By careful examination of the parking area on the pier we were able to obtain small mollusks attached to pieces of nylon or dead seaweed. Some of these, like small Nassarius tiarula (Kiener, 1841)^ were still alive. The shrimp were taken from the boats in large baskets filled with crushed ice and loaded directly into small commercial trucks. It was amazing to us to see local workers sample large raw shrimp, eating them directly from the shell. We did most of our collecting at two beaches just north of the city. One col- lecting site was the beach area, both sandy and rocky, adjacent to the rather new El Presidente hotel about two to three miles from town. Another was Playa Tesoro, approximately five miles north of the city, a lovely sandy beach with palapas bounded by rocky areas. Recent reports on collecting in the Gulf of California at such sites as Guaymas, Bahia San Luis Gonzaga, and Escondido Bay indicated sharp reductions in intertidal and deep water species, possibly as a result of 'El Nino.' Our collecting was limited to the intertidal region and compared favorably to our 1970 collecting at La Paz. We did not find the live Strombus^ Coniyi.s, Cypraea^ and Terebra species that Roland Taylor (1970) had found on the beaches north of La Paz in January 1970, nor had we when we collected in March 1970. Some of the species like Strombus graailior Sowerby, 1825 and S. granulatus Swainson, 1822 apparently are found intertidally in large quantities for brief periods and then disappear from the intertidal zone. In March of this year our collecting was limited to the following sites: 1. Beaches in central La Paz from Los Arcos hotel to northern end of business district, 3/16/84, 3/19/84 2. Beach at El Presidente hotel, approximately 3 miles north of La Paz business district, 3/17/84 3. Playa El Tesoro, approximately 5 miles north of La Paz business district, 3/18/84 4. Commercial fishing pier in center of town, 3/20/84 Page 67 THE FESTIVUS Vol. XVI(6) 1984 Even at very low tides, the beaches in the central portion of the city, both north and south of the commercial pier, remain very narrow. In some areas, large boulders are exposed. Some live mollusks were found there, but most of the shells we saw in this area were single valves of clams or crabbed and weather-beaten gastropods. It is possible that deep-water species might occasionally be found in this area as a result of the wash- ings from the nets of the commercial shrimp boats . As we walked north of town, the beaches became wider and were occasionally separated by outcroppings of rocks. We spent some time turning these seemingly barren rocks, and in the gravelly sand beneath we found many black sea cucumbers approximately one inch in diameter and six inches long. Attached to these animals, we found a number of minute species such as: Rissoi-na otandestina (C.B. Adams, 1852), Caeoim alathvatim Carpenter, 1857, and Odostomia sp. (see Figure 1). As we travelled further north to the El Presidente hotel and to Playa Tesoro, the beaches became sandier and were bounded by Fig. 1. Odostomia sp. found on a sea cucumber. Length: approx. 2 mm. rocky areas. In these latter areas there was a var- iety and abundance of species on the undersides of rocks . We had difficulty Identifying some of the smal- ler gastropods. Figure 2 is a beautiful pyramidellid which most closely resembles Pyramidetta auricoma Dali, 1889. However, it doesn't have the yellowish white color and fine golden-yellow spiral lines of P. auriooma. Since our specimen was dead collected, it is possible that these features could have been eliminated by wear. Figures 3 to 6 are photographs of the apertural and dorsal views of two different Oliv&t'La species which we were unsuccessful in identifying. For a list of the species collected, see Table 1.

MULLINER 5283 Vickie Drive, San Diego, California 92109 In the spring of this year, a group of us spent our Easter vacation camping, diving, and fishing in Escondido Bay. (See Figure 1). The stark rugged mountains in this area framed the back of our camp (Figure 2). Brilliant sunrises appeared over the Gulf of California; and Dan- zante Island (one of six vol- canic and sedimentary islands) rose out of the sea within sight. Many underwater reefs lie near or between the islands and some of them come to within 30 feet of the surface and drop, on their outer sides, to 1000 feet or more. Our group had been camping here for almost a week when, on Thursday morning, we decided to take Ken and Marge Lindahl on a dive off a special reef we knew. Bob and Dimitri Yin went in the Zodiac and Marge, Ken, and I in the aluminum boat . When we dropped the anchor it went to 60 feet instead of stopping on the reef at 30 feet I dove down the anchor line to find out where the reef really was . The anchor lay in sand near the reef and as I swam a circle around it, I noticed the characteristic trails of sand dwelling gastropods. The trails were probably made the night before and were mostly obliterated by the currents. One trail did seem to have a lump at the end of it, however. I slid my hand under the lump and up came a 96 mm OHva porphyria in perfect condition and extremely beautiful with Fig. 1. Our campsite at Escondido Bay Fig. 2. The mountains behind our camp Vol. XVI (6) 1984 THE FESTIVUS Page 72 its tan spotted mantle exposed. See Figure 3 for an illustration of the shell of 0. porphyria I returned to the boat and took Marge and Ken on a survey of the reef. We saw Muriaanthus prinaeps. Conus nux, Spondylus prinaepSj Spondylus oalcifer^ and several spiny lobsters. The reef was covered with gorgonians, hydroids, and algae. Many varieties of tropical fish — damsel, butterfly and wrasse swam through the canyons and caves. We later shore collected, snorkled, and en- joyed the sun in a nearby cove before heading back for camp. I went back into the water to have another look at the sandy area at about 60 feet. On following a trail in the sand and discovering a lump at the trail's end, I found another Oliva porphyria 94 mm long and in per- fect condition. Ken said we ought to call this unnamed inlet "Martini Cove" for the olives in it! Fig. 3.

Page 74 THE FESTIVUS Vol. XVI (7) 1984 COLLECTING IN GUADELOUPE AFTER HURRICANE DAVID BY RICHARD HERRMANN 1251 Hornblend #19, San Diego, California 92109 From the safety of my fourth story hotel room, I observed the greatest display of power that I had ever seen! Lethal projectiles disguised as coconuts were slamming into the windows below. Palm trees, pushed to their limit, were snapping easily in the 100 mile an hour gusts. Most Impressive were 30 foot storm waves pounding the usually placid Caribbean shoreline. I happened to be working at the Club Med on the French island of Guadeloupe in 1979. That August^ Hurricane David became the strongest hurricane in 50 years to hit this part of the Antilles. The destruction was widespread; some Guadeloupeans were killed and banana and sugar cane crops were extensively damaged. Club Med shut down and cleanup operations began. With plenty of free time, my co-worker Denis Heron and I began a search for any mollusks that might have been cast up by the tremendous waves. The first few days were not very productive, with only a few specimens of broken Strombus gigas Linne”, 1758 and Conus sp. to show for our efforts. Five days after the storm, we took a small boat to explore beaches to the north. Stopping at a small, sloping gravel beachjWe found something incredible! Fig. 1. Apertural and dorsal views of Charonia variegata Lamarck, 1816 Vol. XVI (7) 1984 THE FESTIVUS Page 75 Hundreds of living mollusks had been thrown onto this tiny beach by the storm. Most noticeable were large Cassis tuberosa^ Linne", 1758; Cassis madagasaariensis Lamarck, 1822; Stromhus gigas; and Chavonia variegata Lamarck, 1816 (see Figure 1) . Many of these were oozing green rotten flesh from their apertures and the stench was almost unbearable. We also found Stromhus pugiZis Linne^, 1758 (see Figure 2) in large numbers along with some Stromhus raninus Gmelin, 1791. Others in moderate numbers were: Astraea phoehia Roding, 1798; Cittarium pica Linne, 1758; Nerita peloronta Linne", 1758; Phalium granulatum Born, 1778; Phyllonotus pomum (Gmelin, 1791); and some beautiful examples of Cypraeeassis testioulus Linne", 1758. Further exploration yielded some Cyphoma gibbosum Linne", 1758, and a handsome Cypraea oervus Linne, 1771. Perhaps the most exciting find was a Cymatium femorale Linne, 1758 in excellent condition. Fig. 2. Apertural and dorsal views of Stromhus pugitis Linne", 1758 found on the beach after hurricane David. The shells that we found showed varying degrees of damage from being rolled around by the waves. Some were completely shattered, while others were near per- fect. Large Cassis, mollusks with spines and spires, and juvenile Cypraea were most damaged. Cypraeoassis^ Cyphoma^ Nerita, and Cittarium showed the least dam- age. I have no idea why this particular beach received so many living shells during the storm — there were literally hundreds. Surely offshore bottom topo- graphy and the force of the waves acting together contributed to this phenomenon. Denis and I returned to the beach many times for over two weeks, always amazed at the amount of shells to be found there. Certainly this experience convinced me that collecting after a major hurricane presents a unique opportunity for the diell enthusiast! My thanks go to Dave Mulliner for photographing the two shells Illustrated. Page 76 THE FESTIVUS Vol. XVI (7) 1984 A PRELIMINARY REPORT ON PSEUDOMELATOMA STICTA BERRY. 1956 (TURRIDAE: PSEUDOMELATOMINAE) BY CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park P.O. Box 1390, San Diego, California 92112 In April of this year, Mr. Bob Yin of La Jolla, California brought some mollusk specimens to the San Diego Natural History Museum (SDNHM) for identifi- cation. Among them was a specimen of PseudomeZatoma (Figures 1 & 2) taken in 50 to 60 feet of water off the Coronado Islands, Mexico. Fig. 1. Apertural view of Fig. 2. Dorsal view of specimen PseudomeZatoma stiota from shown in Figure 1 the Coronado Islands, Mexico. This specimen is 29.8 mm in length (protoconch missing) with eight post- nuclear whorls. The ground color is cream to grayish cream and is speckled with small regularly spaced chocolate brown spots. These vary in shape from almost circular to comma-shaped and in the extreme to wavy lines in the sutural area. There is no perlostracum remaining on this shell. With the exception of the body whorl which is smooth, except for slight peripheral swellings early on the Vol. XVI(7) 1984 THE FESTIVUS Page 77 whorl, the postnuclear whorls have 7 to 8 distinct rounded knobs on the periph- ery of each whorl. The aforementioned features made this shell look different than specimens of Pseudometatoma p&n-ia-iltata (Carpenter, 1864) usually seen in San Diego waters. Specimens of P. penioillata in the SDNHM collection are highly variable in sculp- ture and are mostly covered with an olive to brown periostracum which partly ob- scures the pattern beneath. However, .none of the specimens had a smooth body whorl with an overall dot pattern. Dr. S. Stillman Berry (1956:156-157) described a Pseudomelatoma which appears conspecific with the Yin specimen shown in Figures 1 and 2. The holotype of Berry's species, Pseudomelatoma stiota^ is illustrated here (from Berry) in Figure 3. The original description follows . Pseudomelatoma sticta, ii. sp Fig.', 3-G Shell of moderate size, elongate-fusiform, with tall, sharply conic spire; whorls 9+, slightly constricted in front of the suture, the anteriorly thrust peri])hery smoothly conve.x; suture sharply defined; first nepionic whorl and a quarter smooth, mammillate; succeeding whorl rather abruptly showing about 6 fairly sharp spiral grooves and about 10 strong ptotractive axial ribs which do not cross the fasciole; althougli remaining strong for yet another whorl or so, all this sculpture gradually tends thereafter to obsolescence except at the peripher}- where the ribs persist as low rounded knobs, the number of which to a whorl remains about the same until the body whorl is reached, when the entiie later portion becomes practically smooth; spiral grooving particularly strong on the base of adolescent shells, but even in this region lepre- sented only by traces on such a fully mature shell as the holotype. Aperture elongate-pyri- form, about 38 peicent of the height of the shell, widest posteriorly, its posterior angle acute; outer lip modenately thick, sharp-edged, un- armored, produced anteriorly into the short, open, very slightl>' recur\'ed canal; inner lip and columella smooth, weakly sigmoid, covered by a rather thick callus the outer boundary of which is a rathe.' sharp groove in the adolescent shell and a low ridge in the adult. Anal notch distinct, shallow, subjoining the suture; fasciole rather wide, marked principally by the inbowed lines of growth. Color generally a light golden brown, everywhere speckled with small, rounded, dis- crete, dai'k brown spots, in some areas showing a tendency to a cotain legularity of arrangement; the holotype also shows a large, con.sjricuous. Fig. 3. Two views of the holotype of P. stiota from Berry (1956) . blackish brown spot over and immediately in front of the inner lip and there is considerable dark staining cri' a suggestion of banding in the outer wall of the chamber. Measurements: Holotype — altitude 29.5; maxi- mum diameter 9.2; altitude of aperture 11.2; diameter of aperture 4.4 mm. Paratype — altitude 17.3; maximum diameter 6.5; altitude of aperture 7.3, diameter of aperture 2.8 mm. Holotype: Berry Collection no. 23785. Para- type.: Berry Collection no. 23584. Type locality: 26-27 fathoms, Anacajia Passage, Calif.; 2 sjiecimens, Orca, .July 2, 1951. Commentary: Even amid the graceful family of the turiids this is a trimly elegant sjiecies, characterized by the down-sagging (oi' anteiiorl}’ Page 78 THE FESTIVUS Vol. XVI(7) 1984 thrust) nodetl convexity of the whorls comprising the spire, by the eventual obsolescence of the originally sharp axial and spiral sculpture, and by the neatly speckled color pattern. These features separate it from all other members of the genus PscudomclaLoma, with which its ]uesent affiliation can be only tentative in the absenc^e of any knowledge of the animal and particularly of its radula. The shells of both holotj jie and ))aia- tyf)e weie almost completely covered by a hea\'y whitish bloom, apparently limy and j)erhaps algal, Since the type of P. stiota is unavailable for study at this time, I wrote to Dr. James H. McLean, of the Los Angeles County Museum of Natural History (LACM) inquiring if there was any comparative material in the LACM collection which I might study. It is Dr. McLean's view that Berry's P. sti-ota is an extreme variant of P. penioillata. Following is an excerpt from Dr. McLean's letter. "Some years ago I concluded that PseudomeZatoma sti-ota was based on an ex- treme variant of 'penioiZtata in which the nodes become obsolete at an early stage. The color pattern is one that shows up on noded specimens from time to time. It also seems to me that torosa in the north and penioiZtata in the south are the geographic extremes (subspecies perhaps) of one broad ranging species." To illustrate his view he kindly sent two single lots in which the P stiota pattern is present. In the one (Figures 4 & 5). the body whorl is almost smooth and is covered with a dotted pattern while the other whorls are noded on the periphery with the dot pattern apparent. Fig. 4 P. ? stiota LACM 109457 from San Nicolas Is., CA. Fig. 5. Dorsal view of specimen shown in Figure 4. Vol. XVI (7) 1984 THE FESTIVUS Page 79 The other specimen (Figures 6 and 7) has strong nodes on the apertural portion of the body whorl but is only faintly noded in the dorsal view. Occasional patches of the chocolate colored spots can be seen just above the aperture and on the earlier whorls. The dorsal part of the body whorl is almost unpatterned. Fig. 6. Specimen from Farnsworth Fig. 7. Dorsal view of Bank, Santa Catalina Is., CA in specimen shown in Figure 6. 80 to 100 feet. LACM 65-32. Most of the specimens of PseudomeZatoma sti-cta I’ve seen have been taken from deep water, though one of the P. sti-ota specimens in the Barbara Myers collection was collected intertidally at Pt. Loma, San Diego, California. In reviewing the literature it becomes evident that there has been much confusion concerning the apparently oft-named PseudomeZatoma species from the west coast of California and Baja California, Mexico. It is highly likely that Dr. McLean is correct in his assessment of the status of PseudomeZatoma strata as a form of a highly variable species. Acknowledgments I am grateful to Bob Yin for making his specimen of PseudomeZatoma avail- able to me. My appreciation is also extended to James H. McLean for his sugges- tions and for the loan of study specimens of PseudomeZatoma, to David K. Mulliner for photographing the shells, and to Anthony D'Attilio for critically reading a draft of the text. Page 80 THE FESTIVUS Vol. XVI(7) 1984 Literature Cited BERRY, S. STILLMAN 1956.

MYERS The June program entitled, "Philippine Dive Trip" combined the talents of Club members Robert Yin and Twila Bratcher, both veteran Scuba divers and skilled photographers. They showed slides that were a magnificent blend of composition, clarity, and color. In addition to the underwater shots. Bob had slides of the personal shell collection of Victor Dan, his brother. We saw tray after tray of rare and exotic shells. It was most Impressive. On display were photographs taken by Twila and Bob. A small cabinet exhi- bited very rare shells from the Philippines including Cypraea langfordi Kuroda, 1938; C. sakurai-i- (Habe, 1970); C. hirasei Roberts, 1913; Siratus vicdani- Kosuge, 1980; Eomaloaantha anomaliae Kosuge, 1979; Pterynotus loebbeckei (Kobelt, 1879); and Conus exoetsus Sowerby, 1908. Also on display was a tanglenet used by the fishermen of the Philippines to trap deep-water shells. Bob commented briefly on this method of shell collecting. Our Club Science Fair winner, Steven J. Mullin, brought his science project display to the meeting and gave us a brief synopsis of his work entitled, "The Prey Perception in the Larval Grunion Leuresthes tenuis." Steve won a 1st place in his division here in San Diego and also a 1st place at the California State Science Fair in Los Angeles. Steve's experiment involved hatching larval grunion and determining their food intake under different light Intensities. His experiment proved that as the intensity of light increases so does the amount of food eaten by larval grunion. These results could lead to comparisons between the food habits of grunion larva and other larval fish in the same family. Fur- ther, if one determines the light intensity at a specific ocean depth, predic- tions can be made concerning the quantity of food consumed by grunion larvae. Business meeting: Minutes for May 1984 were accepted as printed in The Festivus. The September party was discussed. [See page 81 -Ed] . There was no new business. The cookies were donated by Carol Burchard, Barbara and Wes Farmer, and Mary and John Flentz. Vol. XVI (7) 1984 THE FESTIVUS Page 81 THE ANNUAL SEPTEMBER PARTY The date for the September party has been changed from September 8 to September 15 because the earlier date conflicts with the Underwater Film Festival which many of our members attend. The Club party on September 15 will still be hosted by Margaret and Dave Mulliner and the theme remains Oriental as planned. Please mark you calendars and plan to attend. Further details will be announced later and maps will be provided. TWENTY FIFTH ANNUAL UNDERWATER FILM FESTIVAL On September 7 and 8, the Underwater Photographic Society will present its 25th underwater film festival. Jack McKenney, one of the top underwater cine- matographers in the world today, will be Master of Ceremonies.

HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 This interesting species has long been a problem for two reasons. First, it appears to be a very variable species with a wide geographical distribution and secondly, its generic placement has never been certain. IMarchia martinetana (Roding, 1798) is a strikingly beautiful species well documented as occurring from the Red Sea to the Philippine Islands and across half the Pacific Ocean to Hawaii. The highly colored and sculptured specimen, 26.8 mm in length, (SDNHM 83111) shown here in Figures 1 and 2 was taken in 75 to 100 meters in the Bohol Straits, Philippine Islands. The aperture is pink, the ground color is cream with orchid pink on the fronds and a brown stain in the depressed areas of the varices. This is one of two forms illustrated in Abbott & Dance (1982:139) well known as occurring in the Philippine Islands. The other form figured there is almost entirely golden and both forms are cited by Abbott & Dance as occurring in the southwest Pacific.

Vol. XVI(8) 1984 THE FESTIVUS Page 84 A form from Eilat in the Red Sea shown here in Figures 3 and 4 (SDNHM62886) is 33.9 mm in length and has a yellowish brown shell with a creamy yellow aper- ture. The spines are brown stained terminally with brown in the depressed areas of the varices. It appears to have a stronger somewhat stockier shell. Fig. 3 1M. martinetana from Eilat, Fig. 4. Dorsal view of specimen apertural view. (SDNHM 62886) shown in Figure 3. Other specimens previously examined by the senior author^ which were obtained from Aryeh Hadar (now deceased) in the 1960's from the Gulf of Aqaba, show the same characters as the specimen shown in Figures 3 and 4. A form from Hawaii is illustrated in Kay (1979 : 238 , fig. 83f). Her specimen is similar to the golden form in Abbott & Dance but with a flange which almost connects the scaly spines and extends as far as the terminal portion of the spines. Fair (1976:57, fig. 167) in referring to the sculpture of the Hawaiian form states that it "...usually bears more fimbriations on the varices rather than the two or three frondose extensions on specimens from other areas." A ?form from Mauritius (SDNHM 82994) is shown in Figures 5 and 6. It is 39.9 mm in length and has a stocky, fusiform shell. In this well-preserved specimen there is no indication of the lengthening of the cords into spines. The spiral cords are arranged in the same manner as in specimens of M. mavtinetana with spines. The first three whorls of the teleoconch are white (protoconch worn) . The shell is suffused with burnt brown on the cords and varices to cream with brown stains in the depressed area of the varices. The aperture is white and the apertural dentition is the same as in the other forms . A large shell 40.3 mm in length (SDNHM 79336) was collected in Subic Bay, Philippine Islands in 1958 by diver N.D. Pascall, a navy man. It is shown in Page 85 THE FESTIVUS Vol. XVI(8) 1984 Fig. 5 ?form of 1M. mavtinetana from Fig. 6. Dorsal view of specimen shown Mauritius (SDNHM 82994), apertural in Figure 5. view. ex Levine collection. Figures 7 and 8 and is similar structurally to the one from Mauritius shown in Figures 5 and 6. This is a worn specimen. The sculptural elements are apparent but the color is lacking except for the brown stains in the depressions. In reviewing the literature of this species, we were surprised to see the figures of fenestvatus (the earliest name for martinetana) first illustrated by Chemnitz in his non-binomial work on plate 161, figures 1536 and 1537. It is reproduced here in Figure 9. This form is very different than that illus- trated by Sowerby (1841, fig. 41) (shown here in Figure 10), Reeve, and later workers. Reeve (1845, pi. 15, species 58) still credited the species to Chemnitz but illustrated a delicately frondose specimen which is reproduced here in Figure 11. In Reeve's comments he stated that he considered his specimen to be the same species as that figured by Chemnitz and other early workers though he thought that they had drawn worn and imperfect specimens which did not show the "fimbriated digitations . " What is strange is that the specimen shown here from Mauritius in Figures 5 and 6 (SDNHM 82994, ex Morris Levine collection) is not a worn specimen at all but a well preserved one which very closely resembles the one in Chemnitz. The worn Subic Bay specimen (Figures 7 and 8) also resembles that in Chemnitz. With the exception of the coloration and its complete lack of "fimbriated digitations," these specimens compare favorably with that figured by Reeve and with other frondose specimens from the SDNHM collection shown here. One won- ders if this stout, smooth form is the same IMarchia martinetana , a subspecies, or another species entirely.

Fig. 11 from Reeve 1845 Page 87 THE FESTIVUS Vol. XVI (8) 1984 The generic placement of IMarahia martinetana has long puzzled workers, as can be seen in the following summary of the various binomens used for this species beginning with Sowerby’s figure in the CONCHOLOGICAL ILLUSTRATIONS. Note: With the acceptance by the International Commission of Roding’s work (1798), many long accepted names had to be replaced. Murex fenestratus (IMarah-ia) was first used validly by Dillwyn (1817). This was followed by many mid 19th century authors such as Lamarck, Sowerby, and Reeve. However, the Roding (1798) name mavtinetana is the first valid name on the basis of priority. For the senior author it has been a long unsuccessful quest to obtain specimens of even one form with the soft parts intact so that a radular study can be made. Examination of the radula and the operculum would enable a generic placement of the species as well as possibly giving evidence to substantiate the polymorphic nature of the species. Our appreciation is extended to David K. Mulliner who photographed all the specimens.

Vol. XVI (8) 1984 THE FESTIVUS Page 88 TAN6LENET USAGE IN THE PHILIPPINES BY ROBERT YIN 1275 Torrey Pines Road, La Jolla, California 92037 In recent years, shell collectors have often heard about shells collected by tanglenets. Questions frequently asked are: how do the fishermen apply this method, why do they use the particular method to get shells, and what kind of shells can they get with tanglenets? Earliest use of the net was probably started by fishermen in the Cebu, Philip- pines area who accidentally found shells on fine-mesh gill nets while catching fish. In the early 1960 's after successful netting of some very rare shells such as Conus gloviamaris i there evolved specially designed nets for shelling. The proceeds from these rarer, and thus higher priced shells, provided the financial resource for building the more elaborate nets. Current designs vary in length, width, and in the application of weights and floats. Generally, however, monofilament nylon is used to make the basic 30 x 30 mm gill net material. Figure 1 shows a typical style which eight feet by 100 feet or s in length. In order to ena the net to sink, 15 to 30 grams of lead weights are a tached about 60 cm apart al one of the long edges. On opposite long edge, small pieces of foam about 30 x 7 are attached at about 60 cm intervals so that this long edge will float. Thus, ideally, the net would stri out like a tennis net. The one corner of the net is co nected to a tether line wit a marker float which rises near the surface of the wat The nets are usually s at a depth of 80 to 350 met for one to seven days. Ideally, they are to be set on a sandy bottom fully stretched out. However, they most often sink into a tangled pile, and they are often caught on coral heads and in currents, and they get torn up or lost. It requires three to four strong men to raise the net. The animals of the shells often grab the net as it is pulled. I was told that sometimes the fisherman has to cut the net to get the shells. In the Philippines, tanglenet operations are generally confined to the south- central regions of Cebu, Bohol, and the Gulf of Davao about 120 miles south of Cebu. These areas fall in the latitudes where hurricanes seldom occur. Therefore, the tanglenet operation can be carried on throughout the year. Furthermore, it takes Fig. 1. Untangling a tanglenet. Page 89 THE FESTIVUS Vol. XVI(8) 1984 patience and hard work to operate the tanglenets. It is interesting to note, that the tanglenet fishermen are mostly related, and are well-known for being enter- prising, risk-taking, and hard working — characteristics which are essential to the success of tanglenet technique. Apparently, deep water marine mollusks from slippery and glossy cypraeas to spiny murexes are caught on tanglenets, while very large and heavy shells fall off the nets and cannot be caught with this technique. Some examples of the shells that have been caught using tanglenets are: Conus gloviamavisj Cypraea guttata^ Cypraea leucodon^ Cypraea valentia^ Latiaxis oelinamarumaej and Murex oelinamarumae. I would like to thank my brothers Donald and Victor Dan for providing me with much of the information. BOOK REVIEW BY BARBARA W.

MYERS The lecture and slide presentation "Easter Adventure in Escondido Bay" by Ron McPeak, senior biologist at Kelco, was enthusiastically received by a record crowd. As usual his photographs were technically professional and aesthetically of the highest quality. Ron’s expertise in the field of marine biology insured a selection of interesting and colorful marine invertebrates. A. touch of humor throughout the lecture made it a delightfully lighthearted evening. A mini-lecture was given by Anthony D'Attilio, Acting Curator at the SDNHM. He identified someSO rare and exotic shells mostly murex from a slide taken by Robert Yin of specimens in the collection of his brother, Victor Dan of the Philippine Islands. Tony not only identified, but gave us the history of each species and a brief account of any unresolved taxonomic problems. Business meeting: June minutes as appeared in The Festivus were approved. Pres. J. Hertz announced our next meeting date would be moved to August 30, 1984 since the regular meeting date of August 16th, conflicts with the WSM meeting in Santa Cruz. Many of our members are planning to attend and give papers. The date of the September party has been moved to September 15 so as not to conflict with the Underwater Film Festival. Steven Long, editor of "The Opisthobranch" announced a change in name for this publication to "Shells and Sea Life." June King has volunteered to act as chairman in charge of menu and food for the September party. The menu will be in harmony with the Oriental theme. [Farther information will be available at the August meeting. Ed.] FOR YOUR INFORMATION The Club's annual September party, this year with an Oriental theme, will be held at the Mulliner's home on Saturday evening, September 15. Details will be announced at the August meeting and a map will be included in the September issue of The Festivus. Plan to attend. If you wish to attend the Western Society of Malacologists Meeting (WSM) at U.C. Santa Cruz, August 16-19, 1984, call immediately for reservations to Margaret Mulliner, treasurer, (619) 488-2701.

Page 92 THE FESTIVUS Vol. XVI (9) 1984 BOOK REVIEW BY ANTHONY D'ATTILIO Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 RARE SHELLS OF TAIWAN IN COLOR By T.C. Lan. 1980. Published in Taiwan 144 pages, 160 figures in color, book size 8^1 x 11 inches Price: $21.25 hardbound A recent shell book directed towards collectors and shell connoisseurs might be hardly noticeable among the many that have appeared so frequently in the last few decades. It is hardly conceivable that when I started shell col- lecting close to fifty years ago, the market was limited, essentially, to Walter Webb’s, HANDBOOK FOR SHELL COLLECTORS. Modern books, done with high technology photography and fine coloration are a far cry from that period. Especially noteworthy are the large sized costly "cocktail table books" illustrated beautifully and a treat for the eye even if sparingly supplied with worthwhile scientific Information. A very fine example of a book which is a visual treat in many ways is T.C. Lan's book, RARE SHELLS OF TAIWAN IN COLOR. Although limited in the number of species treated, those Illustrated, numbering 118 in part one of the book, are examples of the best modern color printing; the shells very clearly defined on a black background. The species figured are of shells sold as "collectors items" in today’s market. Each page has, at most, four to five larger than life size figures. Short comments and actual sizes are given for the species illustrated in the bilingual text. The specimens Illustrated are of superb quality but hardly conducive to grasping the considerable gap between the "gem" specimens and the "common folk" shells found in all living populations. A second portion of the book deals with malformed shells and is illustrated with as much artistry as the perfectly formed specimens. However, personally I hardly enjoy looking at malformation in any portion of nature. Following the above are a few photos devoted to molluscan shells covered, in part or wholly, by coral or other extraneous marine organisms which use dead or living shells as a substrate on which to grow. Large collections of such unique oddities have been gathered by a few collectors. Also covered in this book are examples of carvings in jade or bone in some likeness of shells, with an emphasis on Cypvaea. Also included are illustrations of bas-relief carving on shells or further embellishment of shells with jewels and precious metals. Although the examples of such craftsmanship shown in this book are all of oriental origin, this craft was practiced widely in the Greco- Roman world and the art continued into the Florence and Rome of Medici times as well as in other areas of Europe. Such works, requiring a high degree of craftsmanship were to be found only in princely courts. A page of Taiwan stamps with sea shells illustrated closes this book. Vol. XVI(9) 1984 THE FESTIVUS Page 93 THYCA BY TWILA BRATCHER 8121 Mulholland Terrace, Hollywood, California 90046 When we were diving in Papua New Guinea a few years ago, Olive Schoenberg found a Thyaa arystaZtina (Gould, 1846) parasitic on a blue Linakia sea star. Ever since then 1 have turned over every blue sea star I have seen hoping to find the same species. In New Guinea I did find a StiZifer Zinak-iae Sarasin & Sarasin, 1887, almost buried in a gall on a Li-nakia starfish, but no Thyaa. Thyaa avystaZZina is a beautiful small (about 10 mm) limpetlike, al- most translucent white shell with attractive sculpture. It is para- sitic on two species, Linak-ia Zaevigata Linnaeus and L. muZt'tfZora Linnaeus. The female has strong slightly nodulous ribs. The male is smooth, almost microscopic, and lives on the right side of the foot of the female. In spite of its shape, Alison Kay (1979) in HAWAIIAN MARINE SHELLS transferred it from the Capulidae to the Eulimldae since it has a distinctly eulimid proto- conch and is in parasitic association with echinoderms. Over the years I have probably turned over a thousand sea stars in Mexican waters looking for the Panamic counterpart of Thyaa arystaZZinaj T. aaZZista Berry, 1959, also without success. On a recent trip with the Divemaster Seafarl Dive Club in the town of Anilao in the Batangas area of the Philippines, I found plenty of Linakia sea stars to turn over. For days my diving companions Figure 1. Thyaa arystaZZina (Gould, 1846) watched me pick up a sea star, examine it, and then abandon it. Then I found Thyaa \ A few sea stars later I found another one and then a sea star with several. My trip was made,' but “I still have not found the Panamic Thyaa aaZZZsta. My appreciation to David K. Mulliner for preparing this black and white photograph from my color slide. Page 94 THE FESTIVUS Vol. XVI (9) 1984 INSTRUMENT VEST FOR USE IN THE FIELD BY WESLEY M. FARMER 11071 Lea Terrace Drive, Santee, California 92071 The vest illustrated here in three drawings by the author was made in the early 1970 's for work in the Gulf of California. I designed the vest to elim- inate the inconvenient carrying of notebooks, clipboards and the like while recording the nudibranchs and other sea life observed during periods of low tides. The information here was included as a small segment of a paper pre- sented to the 1984 meeting of the Western Society of Malacologists . The vest, shown in Figures 1-3, fits over the head and rests on the shoulders. It buttons at the sides and is fastened under the belt by straps that are buttoned. A thermometer and a metric rule are in pouches in front and the lining at the base of the vest has an elastic in it for a better fit around the waist. The tape recorder is in a plastic lined pouch on the back with a microphone in front. The wire from the tape recorder and microphone passes through holes behind the pouches. There are both voice activated and manually operated microphones. I have tried both. My first attempt in the field was with a voice activated micro- phone and it was found that the surf continually activated the microphone. I now use a manually operated microphone to record my observations and it works very well. Upon returning home, the information is transcribed for evaluation.

MYERS Craig Cary, of Scripps Institution of Oceanography, gave a very instructive lecture on the aquaculture of the rock scallop, B.inri'ttes giganteus (Gray, 1825) based on his experiments with the spawning and rearing of larval Einni-tes. One of the startling occurrences that he illustrated in his talk is that of the com- plete reorganization of the body of the scallop as it reaches the metamorphic stage. Slides, drawings and diagrams illustrated this most informative talk. The rapid growth of Einnites ^ 10 cm in two years according to Cary, would seem to indicate that the culture of this marine organism could be a profitable commercial venture. As a second phase of his lecture, Cary brought in a specimen of Catyptogena magnifica Boss and Turner, 1980, the large white clam from the hydrothermal vents brought up by the "Alvin." The organisms found at these sites obtain nutrients from chemosynthetic bacteria that oxidize the hydrogen sulfide seeping from these vents; and utilizing the energy released, transform carbon dioxide in the water into organic carbon. At present he is working on habitats in the shallow subtidal with high concentrations of hydrogen sulfide. Some molluscan species in the family Lucinidae living in these anoxic conditions have been found to utilize similar chemosynthetic bacteria. The business portion of the meeting followed the coffee break. The July minutes were accepted as they appeared in The Festlvus. On September 15th we will hold our annual fall party, this year with an oriental theme. It will be hosted by Margaret and David Mulliner in the garden of their home in Pacific Beach. June King has prepared the menu which will be chicken teryaki, stir-fried vegetables and fresh fruit compote. Everyone attending is asked to bring one of these dishes. Contact June for recipes (619-296-0574). Come in oriental dress if possible. President Jules Hertz announced that the Botanical Garden Foundation is holding their Annual Fair on October 7th at the Casa del Prado. They are asking member organizations to participate. The Board recommends that we par- ticipate. We need a chairman and a committee. Wesley Farmer volunteered to be on the committee. Please contact Jules Hertz or a Board member if you will help. Aquarium, slides, or specimens for display are recommended. NEW MEMBERS Stevens, W.

DURING NOVEMBER 10-14. 1981 BY JULES HERTZ and CAROLE M. HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 This paper is a modification of a presentation given 17 August 1984 at the 17th Annual Meeting of the Western Society of Malacologists in Santa Cruz, CA. On 8 November 1981, five of us left San Diego, California headed for Pdnta Asuncion, Baja California, Mexico. This group consisted of David K. Mulliner (Research Associate, San Diego Natural History Museum), Ron McPeak (Manager of Marine Biology at Kelco), Mike Jennings, also of Kelco, and the authors. Punta Asuncion is located on the west coast of Baja California between Scammon’s Lagoon and Magdalena Bay, approximately 600 miles south of San Diego. The authors had never travelled this far south on the west coast of Baja California, and we were particularly interested in this area since it contains a combination of Californian and Panamic fauna and is rarely visited by amateur or professional malacologists . To quote Frank Rokop in D.L. Bostic's A NATURAL HISTORY GUIDE TO THE PACIFIC COAST AND NORTH CENTRAL BAJA CALIFORNIA AND ADJACENT ISLANDS, "The student acquainted with the seashore life of Southern California will be familiar with most of the intertidal animals of the northern Baja California coast. In fact, virtually the same fauna occurs from Santa Barbara, California south to Scammon's Lagoon. Along the southern half of the Peninsula, however, the fauna changes. Here a tropical fauna begins at Magdalena Bay and extends through the Gulf of California to Peru. Between Magdalena Bay and Scammon's Lagoon is a region of overlapping faunal elements, the stragglers, from both the north and south." The trip to Punta Asuncion took 1^ days, and we camped the first night in the area of Catavina among the elephant trees, cardons, and boojum trees. On the second day, we traveled south beyond Guerrero Negro to Vizcaino and then turned west to Punta Asuncion. The last 80 miles is on a dirt road. The Mexican government was just working on an improved road which consisted of rocks from fossil beds near Turtle Bay. This was to be the foundation for a paved road. After a few miles of this rough substrate, we decided to continue on the old dirt road. As you approach Asuncion Village (San Rafael), the road improves. In some places it has been cut through large dunes of fossil filled coarse sand. Ron McPeak and Dave Mulliner had flown in to the airstrip at Asuncion Village several times previously as part of Ron's survey of the kelp beds and were familiar with the area along the Baja coast. Figure 1 is a map showing a portion of the west coast of Baja California in the general vicinity of Punta Asuncion. Figure 2 is a map of the local area of Punta Asuncion showing the village of Punta Asuncion, Isla Asuncion, and Asunclo'h Village. After a brief stop in the Village, we continued a couple of miles northwest and set up camp on a ledge running parallel to the rocky beach (approximately 25 feet above the level of the water) . Vol. XVI (10) 1984 THE FESTIVUS Page 99 Fig. 1. Map showing portion of the west coast of Baja California in the general vicinity of Punta Asuncion. (Map is not to scale) . T The coastal area looks very similar to La Jolla, California if you eliminated all the houses, paved roads, tourists, and other signs of development. Figure 3 shows the appearance at low tide of the beach located below the campsite. The rocks were turnable and supported a large quantity of sea life. The rocky beach on the south side of Punta Asuncion was similar in composition. The cliffs are full of fossil mollusks and walking along the cliff's edge we found many exposed fossil specimens. These were generally similar to Recent species we collected, but in addition included specimens of Conus fergusoni- Sowerby, 1873 and Thais bisevialis (Blalnville, 1832). On^the first morning at Punta Asuncion, we paired off. The authors were the primary collectors scale) . Page 100 THE FESTIVUS Vol. XVI(IO) 1984 of intertidal animals and shells, while Mike, Ron, and Dave went off in an 18 foot zodiac. Mike fished and tended the boat while Ron and Dave dived. They were primarily interested in exploring and underwater photography and Dave col- lected bottom samples (commonly called grunge) o f coarse sand and mud con- taining microscopic specie Few of these were live collected. This routine of collecting continued for the next four days. On several occasions, a number of the group visited the large expanse of sandy beaches forming the coastline so^utheast Collecting area below campsite at low tide. of Punta Asuncion. A typical expanse of one of the sandy beaches is shown in Figure 4. The ledge separating the desert terrain from the beach was full of fossil shells. See Figure 5. There were large rocky outcroppings at the ends of the sandy beaches we explored. These rocks were completely covered with the anemone Anthopteura elegan- tissima and few of the rocks were turnable. We found little in the way of live mollusks on these sandy beaches with the exception of Donax gouldii Dali, 1921. Dave joined us one afternoon and we collected a bucket full. These were used to prepare a delicious stew of mollusks, fresh fish and lobster, the latter given to us by a local fisherman. Asuncion Village appeared prosperous even though it has to acquire its fresh water by ship from Cedros Island. A cannery, originally set up to process tuna, now is processing lobsters, abalones and Astraea undosa, the latter processed as conch. The lobsters are shipped to the U.S., the abalones to Japan, and the conchs to other parts of Mexico. Fig. 4. A typical sandy beach south of Asunclo'n Village. Vol. XVI(IO) 1984 THE FESTIVUS Page 101 Fig. 5. Fossil shells on ledge above sandy beach. During our walks around the point, we found large mounds which contained many thousands of Astn?a&a opercula. Dave and Ron surveyed underwater sites off Isla Asuncion, Isla San Roque, and a seamount three miles west of Isla Asuncion. They saw large schools of colorful fish such as "blacksmiths," bottom areas rich in soft corals and anemones, and at a depth of 70 feet saw occasional nudibranchs such as Flab etZinop sis iodinea (Cooper, 1863) shown in Figure 6 and Coryphella tvilineata O'Donoghue, 1921. Abun- dant during our visit to Punta Asuncion was the pelagic red crab Pleuronoodes planipes. Figure 7 is a photograph (taken underwater by Ron McPeak) of one specimen with commensal Leptopeat on its first legs. Sev- eral areas on the beach south of Punta Asuncion were covered with many thousands of these pela- gic crabs washed in from deep water. Our brief stay in Punta Asuncion resulted in the collection of 51 bivalve species, 136 gastropod species, 7 chiton species, and one scaphopod. The col- lecting sites are de- tailed in Table 1. In Table 2, we've listed the species collected systematically according to Keen (1971) and have re- ferenced the species by Keen's numbers in SEA SHELLS OF TROPICAL WEST AMERICA Fig. 6. Flabellinopsis iodinea (Cooper, 1863) or McLean's numbers in MARINE SHELLS OF SOUTHERN CALIFORNIA. Most of the bivalves were dead col.lected, and in many cases only single valves were obtained from the bottom samplings. Figure 8 shows the prodis- soconch and the hinge area of one of the most beautiful of the minute bivalves collected. We originally thought that this 2 mm shell must certainly belong Page 102 THE FESTIVUS Vol. XVI(IO) 1984 in the Cardiidae, and we searched the literature for many hours before we found that it really belonged in the Mytilidae. Based on Keen (1971) , we have identified this bivalve as Cvenella divaviaata (Orbigny, 1846). The type locality of Orbigny 's species is Cuba, but most West American authors have felt that Pacific specimens were not distinct enough to warrant specific separation. Keen describes the shell as white. The specimens we found had a light yellow periostracum. Another small bivalve ob- tained from the grunge was Cvassinella paadfiaa (C.B. Adams, 1852). Figure 9 shows the exterior view of one valve of a 4 mm long specimen. Under high magnification, we observed a pattern formed by the incised striae which gives it the appearance of webbing. In larger specimens collected, this pattern had been worn away. A review of the bivalve portion of Table 2 shows that a majority of the bivalves collected are from the Californian Province. Collecting intertidally , we obser- ved a number of juvenile HaZi-ot'Cs. This is in contrast to the rarity of juveniles observed along the San Diego beaches. The larger shells such as limpets and tegulas that are common in San Diego were also common in the rocky ^reas on both sides of Punta Asuncion. Almost all of the microspecimens were obtained from the grunge collected in 30 to 100 feet of water. We had been particularly looking fo the species described by Bartsch as Niso hipoZitensis, to support a paper we were preparing in 1981 on EuZimostraaa. The type locality for this species is San Hipolito Point, Fig. 8. CreneZZa divarioata from grunge just south of Punta Asuncion and we were fortunate to find a few in the Vol. XVI(IO) 1984 THE FESTIVUS Page 103 grunge. As with the bivalves, a majority of the gastropods were from the Californian Province. Figures 10 and 11 are two views of a 60 mm spe- cimen of Cevato stoma monocevos (Sowerby, 1841) taken live by Ron McPeak in 55 feet of water off Punta Asuncion in October 1982. Only dead specimens were collected during our visit in 1981. There is still some controversy concerning whe- ther or not C. monoaeros is a valid species or only a form of C. nuttalli (Conrad, 1837), One of the more common intertidal species collected was PseudomeZatoma peniciZZata (Carpenter, 1864). This is a very variable species occurring throughout southern California. Figure 12 shows Fig. 9. Exterior view of CrassineZZa paoifioa Fig. 10. Ceratostoma monoaeros, apertural viev? Fig. 11. Dorsal view of specimen shown in Fig. 10 Page 104 THE FESTIVUS Vol. XVI(IO) 1984 a form which is unpatterned but strongly ribbed under an olive brown perios- tracum. This specimen was collected by Dave in deep water, but others were also found intertidally . The more common form from this area is shown in Figure 13. Carpenter's Type, although very worn, shows the same zigzag markings and ribbing that is typical of the shells shown in Figure 13. Another small turrid we collected was Agathoma stellata (Morch, 1860), and we were particularly pleased with this find since we had never col- lected it before. The 7 mm specimen is shown here in Figures 14 and 15. Figure 16 shows a 47.5 mm specimen of Knefastia prinoeps Berry, Fig. 12. Fig. 13. Pseudomelatoma pema%Llata dorsal and apertural views Pseudomelatoma penioillata, a live collected specimen from deep water 1953. This was taken live by Dave in about 80 feet of water off Isla Asuncion. Other specimens have been taken by Ron on previous trips. We have had one in our aquarium for about four years. One of the more common of the microspecimens collected was Aesopus arestus Dali, 1919. The specimen, which belongs in the Columbellidae, is shown in Figures 17 and 18. It is 7 mm long and was the largest of those found . Although not plentiful, we did find some interesting nudibranchs. These were photographed and identified by Dave Mulliner. In Table 2, the Berthella sp. is probably the unnamed Berthella from Nayarit (Mulliner, pers. comm.), and the Corypkellina sp. was last found in Nayarit (Mulliner, pers. comm.). The Coryphella, sp. shown here in Figure 19 is the same as one figured in Behrens (1980 : 105 , fig. 155). Figure 20 shows a specimen of Dtaulula sandiegensis (Cooper, 1863) taken intertidally.

While diving at Cocos Island, Costa Rica during March 1984, an occasional dead specimen would be found near the base of steep-sloped rock out- croppings around the is- land. I was told that they would be found "higher up on the rocks," but swimming near the surface was usually im- possible. Even during the slack tides that enabled us to collect there at all the strong surge currents would heave you against the rocks and urchins. One day we dove at Dos Amigos (Figure 2) which is two rock pin- looked through shell books. Its large size, sharp Fig. 1. Thais planospira, live collected specimen at left. Fig. 2. Dos Amigos, off Cocos Island nacles jutting above the ocean surface. This is the most spectacular underwater sight at Cocos Island. One of these rock formations has a cavern about 80 feet high running completely through it. The bottom of the cathedral-like tunnel is at 100 feet and the largest fish seen on the trip, such as rays, along with other sea life moved back and forth through it. While looking among and under rocks just out- side the opening, I found a few broken pieces and dead specimens of Thais planospira. Thinking that Page 114 THE FESTIVUS Vol. XVI (10) 1984 if I couldn't find a live specimen here I wouldn't find one at all, I ascended to a depth of about 15 feet. There I found a horizontal ridge and small, hard coral knobs that I could grip firmly and hold on to when the surge hit. Then, during the few seconds of slack, I could pull myself along for several feet and hang on during the next surge. Fortunately, I didn't have to endure this very long before I looked ahead and saw my objective also clinging to a rock — a live T. planospira. Naturally, I then wanted to find another. After advancing several feet, I found that I had moved into a more direct line with the in- coming surge and the only progress would be backwards. I turned back, grateful to escape with the one specimen that I had. This turned out to be the only live taken T. planospira on the trip. Thais planospira may be easier to find in other locations, but the hard work and perseverance required to collect a live one on Cocos Island can result in the addition to your collection of a shell worthy of the effort. [Ed. note: David K. Mulliner kindly made the black and white prints from the author's slides J CLUB NEWS A NIGHT IN THE ORIENT Over 40 members and their guests were part of the festivities on Saturday evening, September 15. There were ladies in kimonos, gentlemen in yukatas, a samurai warrior, and many "tourists." The Mulliner garden was delicately lit and decorated with Japanese paper kites and hibiscus and ginger blossoms. New members and longtime ones had the opportunity to become acquainted over Dave's punch — definitely with an Oriental flavor for the occasion. The menu, in June King's capable and creative hands, was outstanding. All contributed to and greatly enjoyed dinner at large, cloth covered tables on the Mulliner 's patio . The Club thanks Margaret and Dave Mulliner, June King and all the others who contributed to the successful evening in the Orient. CHANGE OF ADDRESS Fried, Jeff. 596 Hermes, Encinitas, CA 92024 IN MEMORIAM Sadly, we report the passing of Ben H. Purdy on September 2, 1984 at the age of 84. Ben died at his home after a long illness. He and his wife, Ruth, were longtime members and friends of the San Diego Shell Club and many of us can recall, with fondness. Club auctions when Ruth would unwittingly outbid Ben for a shell. Our sympathy goes out to Ruth at this time. r 7.

MYERS Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park P.O. Box 1390, San Diego, California 92112 The typological specimens of Murex oyotostoma Sowerby, 1841 were borrowed from the British Museum (N.H.) London. There were two lots of three specimens each labelled probable syntypes, reg. #197463 (Neg. no: 0181) and reg. #1982158. Sowerby gave the type locality as Island of Bohol, Philippine Islands. At the same time, we borrowed typological specimens of Muvex nuoula Reeve, 1845 con- sisting of three specimens labelled syntypes / British Museum (N.H.) reg. #197487. Reeve gave the type locality as Island of Capul, Philippine Islands. Both species came from the Hugh Cuming collection. Murex nuoula has long been considered synonymous with M. ayoZostoma by authors and our studies confirm this. All specimens appear to have been col- lected as empty shells. Favartia oyotostoma as represented by the probable syntyplc specimens cannot be distinguished from the three syntypes of Murex nuouta Reeve. In general. A/, nuoula may be briefly characterized as having a broad biconic fusiform shell; five prominent varices; strong, deeply cut spiral cords; and the remaining intervarical surface embellished with scabrous lamellae. Figure 1 is a photocopy of Sowerby 's original figure of M. oyotostoma (BMNH #1982158) which we have chosen as lectotype. It is one of three in the lot and its dimensions are 25.5 x 16.7 mm. It is shown in Figures 2 and 3. We are designating as paralectotypes the two remaining specimens in lot #1982158 and the three specimens in lot #197463. The dimensions of these paralectotypes are as follows : BMNH #1982158 a. 24.0 x 17.3 mm b. 18. 0 X 13. 0 mm Fig. 1. M. ayalostoma from Conchologlcal Illustrations BMNH #197463 a. 20.0 x 14.3 mm b . 19.6x15.0 mm c. 14.8 X 10.7 mm We are also figuring one of the syntypes o f M. nuouta (BMNH #197487A It is one of three in the lot and its dimensions are 16.8 x 11 mm. It is shown in Figures 4 and 5. What is of particular interest to us is the question of whether or not M. oyotostoma occurs in the Philippine Islands. Of the numerous Favartia species and, more or less morphologically similar, Murexietta species that have come to our attention over a period of years, we have not seen this species from the western Pacific although its occurrence there may still be shown. The syntypes of Murex oyotostoma and M. nuouta show a strong resemblance to Favartia oettutosa (Conrad, 1846) from the western Atlantic. These specimens were, as stated earlier, from the Cuming collection. However, Hugh Cuming, to our knowledge, never collected along the western Atlantic coast. On his third voyage in 1836, Cuming visited the Philippine Islands. His Vol. XVI(ll) 1984 THE FESTIVUS Page 117 Fig. 2.

From letters and other correspondence, we have some knowledge of his travels. He left Manila in November 1839 for Singapore and then stopped at Malacca on the west coast of the Malay Peninsula. He also visited the island of Sumatra before continuing homeward. We assume he travelled through the Indian Ocean and around the Cape of Good Hopey since he stopped for a short visit at the island of St. Helena in the South Atlantic and arrived in London on June 5, 1840 (Dance 1966). Radwin and D'Attillo (1976: pi. 24, fig. 11) referred a specimefl from Zanzibar, East Africa to F. ayolostoma. E.H. Yokes (1978: pi. 7, fig. 5) refer- red a specimen from Mozambique, East Africa to F. ayatostoma and placed Muvex sykesi Preston, 1904 (pi. 6, figs. 7,8) from Ceylon, Indian Ocean in the synonymy of F. oyotostoma. All records are from localities in the Indian Ocean. In the same paper Yokes (1978) cited Tapparone - Canefri (1875) as reporting F. oyotostoma from the Red Sea. D'Attillo (1981:flgs. 1,2) figured a specimen of Favartia sykesi which was erroneously labelled as a paratype. This specimen is shown here in Figures 6 and 7. It was borrowed from the Los Angeles County Museum (N.H.) (LACM #1963). According to Ms. Kathie Way, Gastropod Section, of the British Museum (NH) , the type specimens of M. sykesi were labelled syntypes. Preston did not choose a holotype for M. sykesi. The British Museum (NH) has in its collection the figured syntype reg. #1905.2.8.7, and this specimen is figured in Fair (1976: pi. 20, fig. 293) and in Cernohorsky (1978: pi. 19, fig. 3a) as "Holotype," a designation which we accept. We have been informed by the British Museum (MH) that there are also two probable syntypes of M. sykesi (reg. #1904.5.11.11 and 1904.5.11.12), but there is no evidence to prove that these were part of the type lot although they were presented to the Museum in 1904. Preston gave the Fig. 6. Favartia sykesi (Preston, 1904), Fig. 7.

Specimens of the syntypic lots of Favartia ayalostoma exhibit the following characters with only small morphological variations which are to be expected in living species of all organisms. The syntypic specimens range in size from 14.8 to 24.0 mm in length, are broadly biconic in outline with moderately high spire and deeply impressed suture. There are four to five subangulate postnuclear whorls. The aperture is moderate in size and ovoid; peristome weakly erect; siphonal canal broad, narrowly open; the extreme termination is short, tube- like, and strongly bent back; the siphonal fasclole has two former canals. Five Vol. XVI (11) 1984 THE FESTIVUS Page 121 broad varices are found on the body whorl, the leading side terminating in an edge that is weakly erect and extends to the center of the Intervarical areas; the varices are somewhat sharp and weakly recurved at the crest. The varices continue above the shoulder and at the suture are connected, or closely adjacent to the varix on the whorl above. There are five varices on the spire descending obliquely, relative to the axis of the shell. The five major cords on the body whorl are arranged as follows: two paired cords spaced from shoulder to midway on the body, three on the body whorl anteriorly with the two most anterior smaller and closely paired. There are three or four minor cords above the shoulder and some single intercalary cords on the body whorl and three or four minor cords on the canal. The leading side of the varices has a series of four to six scabrous well-elevated lamellae which continue in the direction of growth to the outer lip of the aperture or Intervarically to former outer lip edges. There are deep excavations between the spiral cords on the receding side of the varices. The color is a uniform dead gray on all the typological specimens. The specimens were collected as empty shells and none have the nucleus preserved ACKNOWLEDGMENTS We thank Ms. Kathie Way of the British Museum (N.H.), Gastropod Section, Mollusca Department, who made type material available to us.

HERTZ Department of Marine Invertebrates, San Diego Natural History Museum, Balboa Park, P.O. Box 1390, San Diego, California 92112 In a two month period from mid August through mid October of this year, the Bursa aatifomioa in our 30 gallon aquarium killed and partially ate three specimens of the anemone Anthopleura elegantissima (Brandt, 1835). It first killed the juvenile and shortly thereafter killed and ate the adult. A third anemone, introduced later, was also killed and partially eaten. Until this time an adult anemone had been in the tank with the Bursa for over two years. Prior to August, the Bursa fed primarily on sea urchins (with an occasional small sea star or sand dollar), preferring the purple urchin Strongytocentrotus purpuratus (Stimpson, 1857). It had ignored a white urchin Lyteohinus piotus (Verrill, 1867) with which it shared the tank for over two years. For a careful study of the feeding of B. calif omioa on S. purpuratus in the aquarium, see Loralynn Williams (1976, Of Sea and Shore, Spring issue, pp. 47-48). Several factors may have contributed to the unusual feeding behavior of the Bursa calif omiaa. During this period we were unable to supply sea urchins, though the Bursa had an adequate supply prior to August. (The Bursa had pre- viously gone through long periods without feeding, even when urchins were available). In August the tank sprang a leak, necessitating replacement to a new tank of the same capacity and shape. This resulted in a change of water and freshly rinsed substrate. (None of the mollusks died following the change). Also, at this time, the water in the tank became warmer than usual as a result of the hot summer weather. One wonders if severe pressures in its natural environment would cause Bursa calif omioa to feed on anemone. Vol. XVI(ll) 1984 THE FESTIVUS Page 123 UPDATE ON MOLLUSKS WITH INDO-PACIFIC FAUNAL AFFINITIES IN THE TROPICAL EASTERN PACIFIC III BY DONALD R. SHASKY 834 W. Highland Avenue, Redlands, California 92373 (Adapted from a paper presented at the Annual Meeting of the Western Society of Malacologists , 1984) During March 1984, I was again able to SCUBA dive at Cocos Island, Costa Rica, along with Captain Gene Everson of Ft. Lauderhill, Florida. This year three additional Indo-Pacific species were found at Cocos Island that have not been previously reported from the tropical Eastern Pacific. These are listed below. Metax-la brunnioephala Kay, 1979. This taxon was described from Hawaii and, to my knowledge, it has not been reported from any other locality. My specimens were found under dead coral at depths of 20-37 meters. Additional dredged specimens were obtained from 100 meters. The specimen shown in Figure 1 measures 1.0 x 4.9 mm. Cymatium ni-aobaricim Roding, 1798. One 38mm live specimen was collected by Gene Everson under a dead coral in 18 meters at Isla Manuelita, Cocos Island. It is shown in Figure 2. A 15 mm fresh dead specimen with periostracum intact Fig. 2. Cymatium niaobaricum Fig. 1. Metaxia brunnioephata Page 124 THE FESTIVUS Vol. XVI(ll) 1984 was also collected by Gene Everson inter- tidally under rocks at low tide at Bahia Chatham, Cocos Island. Mitva ferruginea Lamarck, 1811. One well preserved 51.5 mm dead specimen was found at a depth of 18 meters on sand at Bahia Wafer, Cocos Island. It is shown in Figure 3. Our work at Cocos Island will continue in 1985. Ed. note: The black and white photo- graphs were made from the author’s slides by David K. Mulliner. This paper is an "Update” of previous reports on the same subject.

Mitva fevvuginea THYCA (BESSOMIA) CALLISTA BERRY. 1959 BY HELEN DUSHANE 15012 El Soneto Drive, Whittier, California 90605 After reading a recent issue of The Festivus (September 1984), with the wistful paper by Twila Bratcher regarding Thyaa oaZlista Berry, 1959, I am reminded of an experience at Escondido Bay, Baja California Sur, Mexico with the same mollusk. My husband Joe and I had arrived at Escondido Bay in our camper in early 1970, before the Transpeninsular Highway was completed. We had come in over a rough, hilly, dirt road after having left La Paz at the break of day. We left the main road at Villa Constitucion and made our way from the Pacific side of Baja Cailifornia Sur to the Gulf of California side jolting and lurching from side to side. At last, in the late afternoon, we arrived at our destination. Having read the history of Escondido Bay, (Engelhard! 1929, Missions and Missionaries of California, Vol. 1, Lower California and Clavigero, translation 1937, The History of Lower California) and the difficult times had by the Jesuit missionaries, we were a bit appalled at the smallness of the bay. Not until later did we realize that the good Fathers had very small boats which made it easy for them to ride the incoming tide through the narrow inlet leading to the bay. The name means "Hidden Bay," and it is so landlocked one wonders how it was found by the missionaries. voi. XVI(ll) 1984 THE FESTIVUS Page 125 The following day was Sunday. Just before dawn several Bajaneros arrived in a truck and immediately started fishing in the narrow inlet. With the in- coming tide, the large fish follow the small ones through the inlet and into the bay. They feed as they go. Grabbing a cup of coffee, I went down to the beach to see the men land the "big ones. Joe became so excited at their catches that he was down in short order trying his luck, and successfully too. I am not a fisherwoman so 1 just watched. Looking down 1 couldn't believe what 1 saw at my feet. One of the Bajaneros had snagged a starfish with his hook and in disgust had thrown the starfish up on the shore. It landed at my feet upside down and on it was a specimen of Thyaa oallista, the first one I had ever collected! Like Twila, 1 had turned over hundreds of the sea star, Phataria unifasoialis Gray, in my search for the elusive Thyca. Before we left at the end of the week, we had collected several Thyca oallista on the sea stars in shallow water at low tide; but none that gave me the thrill of the first one. CLUB NEWS FROM THE MINUTES - SAN DIEGO SHELL CLUB MEETING - 18 OCTOBER 1984 BY BARBARA W. MYERS Our speaker for the October meeting was John Duffy of the California Department of Fish and Game. He discussed the recent population explosion of Avgopecten aequisuloatus (Carpenter, 1864), the speckled scallop, in the Agua Hedionda Lagoon at Carlsbad, California. His talk was illustrated with slides showing the scallop in its habitat associated with the eel grass Zostera. This species of scallop has been completely protected by the Fish and Game Laws since 1954. Prior to that time, and especially before 1949, it had been plenti- ful in several lagoons in southern California. The reason for the decline of the populations of this species in the 1950 's is unknown. The Department of Fish and Game is now studying the life history of this scallop to determine if allowing the take of this species will again jeopardize its existence. A similar species, Argopecten iwadians (Lamarck, 1819), found on the east coast of North America is reported to spawn only once in its two year life span. Studies have not yet determined the life span of A. aequisuloatus. To further protect this species until a determination is made on the feasibility of again allowing the take of this species by sports fishermen (f isherpersons) , the Fish and Came is posting the lagoons and bays of California where the species may be making a comeback. Business meeting: The slate of officers for 1985 chosen by the Board in its role as Nominating Committee is as follows: President Martin Schuler Corres. Secretary Dee Miller Vice President Richard Herrmann Treasurer Nola Michel Rec. Secretary Barbara W. Myers Each nominee has consented to serve. Nominations from the floor will be accepted at the November meeting followed by the election of officers. Arrangements for the Club's annual Christmas party were also discussed. (See last page this issue with map for detaching. Ed.). Our appreciation to Debbie Catarios and Marge Bradner for the refreshments at the break. The door prize was won by Margaret Mulliner.
