The Kueneme hydroids consist of about 25 species within 7 to 8 families and though most hydroids are commonly thought of as hard substrate dwellers 14 of the species found were restricted to a soft bottom habitat. The distribution of the hydroids could be attributed to two major factors. The first factor was related to the resuspension of organic floe at the water sediment interface, as most hydroids appear to be suspension feeders. The second factor was the presence of suitable substrates for the hydroids to attach. The tubes of the polychaete Diopatra . which have bits of shell material, and the broken fragments of the sand dollar Dendraster were common settlement substrates. Other polychaete tubes such as Nothria and Mesochaetopterus were unused as substrates by hydroids.

Travels with Olga 24 Queensberry Place, S.W. 7 London, England 22 August 1939 Dear Frieda and Chauncey: Thank you very much for your kind and thoughtful letters. They mean a good deal to me here, even though I must seem dreadfully negligent in answering. I really cannot remember where I left off when last writing to you. Perhaps I have already told you of my thrilling and inspiring trip to Plymouth. I was away four days, but could spend only two of those at the station, because of the train trip to and fro When I returned, I found several interesting letters from America, and a note from the director of the South Australian Museum, whom I had met in Los Angeles. He was then about 1/3 of the way of his trip around the world, and again we met at London. He met many people in central and eastern America that I know, hence we had a good deal to talk about. Now I have made tentative plans for my journey to Stockholm. I must send my baggage separetely, since it would be prohibitively expensive to carry with me (yes, that seemed strange to me too). There is such a complication here of crossing borders, customs inspections, passports, tariffs, etc., that one can draw no homologies. One is allowed only 56 poiunds on a ticket. (In U.S.A. it is 150 lb.) At any rate, the British Museum is allowing me to use its agents and facilities, and I rather think it might be so at the other end (Stockholm). Loss of any of it v/ould be irreparable. London has been a most delightful home during the past 1-1/2 months. I have come to feel very much at ease, and have not the slightest hesitation in trying to find anyplace. Yesterday evening, however, I must have been dozing on the subway, in going from Liverpool St. Station to So. Kensington Station, for instead of coming to So. Kensington, I found myself finally at "Shepherd*s Bush”, way off to the N.W. somewhere. But on the same fare, I was able to get to So. Kensington. The subways here are by far the quickest way to get about, but one sees little. There are 5 different lines, and some places where they overlap. They form subterranean tiers, hence one may go down, down, down, into the very bowels of the earth, A seemingly. When, for a moment the lights go out, way down there, I always experience a sense of terror (a phobia, perhaps). This may be somewhat accentuated by the war propaganda flying about these days. I have been, all afternoon, in a dealer T s place for second-hand scientific literature; the famous shop of Wheldon and Wesley. Being considered perhaps a good potential customer, I was even given tea this afternoon. The manager also was very cordial, and confided much interesting gossip of some of his customers from many parts of the world, some of whom I know, others that I should know. There is one chap from Berkeley, comes in and spends thousands, but is a terrific problem, known well in London (I wonder how I will be known after I leave?) This morning I called on Dr. Harding (at the Br. Mus., working on Crustacea). He and his wife are good friends of my former Berkeley associate, Margit Szabo, now Mrs. John Lockhead. Harding and Lockhead went through Cambridge together. Margit spoke, in a letter to me, of coming to Europe this summer, and since some of John’s people are in London, I thought they might be here. One sees many strange sights in London, Scotch pipers in native costumes, piping and begging for pennies, civilians walking about, their ARP gas masks strapped about them, (ready for any emergency?); tall, four-wheeled hansom cabs, drawn by 2 or 4 beautiful black horses, with an array of liveried footmen and lords and ladies within; "Drinking Fountain and Cattle Association" water troughs along the streets, in active use by man and beast (chiefly horses); hundreds of sheep grazing in St. Jame’s Park, proximal to Ritz Hotel; arrows on street guide posts pointing to Air Raid Precaution subterranean shelters (where some people are reputedly now rearing rabbits, dogs and cats); and everybody has a cat. I could give you page after page of vignettes of things I have seen here and nowhere else, and they are the things that constitute London. One can know London only by living in it for a while, and then, perhaps, it is only a taste. I know I have seen only a very small bit, but perhaps a side that very few are privileged to see. I could get beautiful kid gloves here for 1/10 to 2/10 (that is 45 cents to 70 cents) such as would cost $2 to $4 in U.S.A, But I shall forego the opportunity, I suppose one can get them in France for almost nothing. These are french made. But silk goods are expensive. SCAMIT 1984-1985 TEREASURE 1 S REPORT Financially it was a banner year for SCAMIT. We received a $2,500 check from Chevron Oil Company. The donation from Chevron combined with the increase dues ($5 to $15) enabled us to realize our first goal: to produce the newsletter on SCAMIT's own money without volunteer help. After improving the quality of the newsletter, we can look forward to beginning to produce larger endeavors.

MINUTES FROM JUNE 10, 1985 The 22-24 May Conference by the Association of Systematics Collections on a National Biological Survey (NABIS) was attended by Sue Williams of the Allan Hancock Foundation and Thomas Parker of the Los Angeles County Sanitation districts. The proposal for a national biological survey was highlighted in a February 1984 editorial article of Science . The survey of biological resources would be mainly for the United States but include data from cooperative efforts already underway in Canada and Mexico. Broad benefits from such a survey would include: 1) Coordination of government studies (existing state biological surveys, USDA pest species records, EPA studies, and Fish and Wildlife Service surveys). 2) Production of illustrated identification mannuals and Keys. 3) Centralization of computerized records and data resources. Vol. 4, No. 2,3 4) Report the status of bipta to Congress and federal funding agencies in timely periodic manner. 5) Inventory of germ plasm resources. 6) Provide baseline for monitoring changes of the environment (e.g. chemical contamination and acidification). One of the major tasks of this survey would be the resolution of unreliable taxonomies that result from sexual dimorphism, incomplete descriptions of life hitories, cryptic species groups, and microhabitats. Other tasks would include the development of a hierarchial ecosystem scheme, a register of experts in each taxonomic field, the establishment of quality assurance/quality control procedures for identifications, and the production of synoptic reports used to decide the acceptability of industrial environmental impacts. The drive for federal funding continues. The Planning Committee for for NABIS has already held over 36 meetings with private, state, federal and international officials since 1984. More than 24 scientific organizations, representing over 200,000 scientists in North America, support the NABIS proposal. These include the American Association for the Advancement of Science, American Institute of Biological Science, Entomological Society of America, and the International Congress of Entomology. Over a dozen articles about NABIS have been published in professional journals. Letters of support or requests for futher information should be directed to: Dr. M. Kosztarab, Chairman NABIS Planning Committee Department of Entomology Virginia Polytechnic Institute - State University Blacksburg, VA 24061 New Publications : The Third Edition of the International Code of Zoological Nomenclature will be available July 1, 1985 from: Vol. 4, No. 2,3 Karen Leeburg University of California Press Order Departmen 2120 Berkeley Way Berkeley, CA 94720 (415) 642-4247 The cost including shipping is $21.50. The Association of Systematics Collections has two new books. One is entitled Sources of Federal Funding for Biological Research by P.C. Escherich and R.E. McManus. Topics which are presented include: Which federal agencies issue grants and contracts, examples of projects which were funded, and the ranges and average dollar amounts awarded by each agency, application procedures, eligibility requirements, and the persons to contact in each agency. The price is $15.00 plus tax. The other book is entitled Guidelines for Acquisition and Management of Biological Specimens by W.L. Lee, B.M. Bell, and J.F. Sutton. This book deals with the curation of systematic collections. It's price is also $15.00 plus tax. Both books are available from: ASC Office Museum of Natual History Lawrence, KS 66045 (913) 864-4867 Minoru Imajima and Susan J. Williams have recently published a paper entitled "Trichobranchidae (polychaeta) Chiefly from the Sagami and Suruga Bays, Collected by R/V Tansei-Maru (Cruises KT.65-76)". Bull. Natn. Sci. Mus., Tokyo, Ser. A, 11(1):7-18, March 22, 1985. In it, three new species of Terebellides are described. SCAMIT Picnic : September 21, 1985 was chosen as the date for the SCAMIT picinic, or in other words, the fall equinox festival. The site for this event has been narrowed to either Edison Park in Huntington Beach or Irvine Park in Irvine. Stay tuned for further announcements. A Treasurer's Report will now be made at every monthly meeting. This report will include each months expenses, income and receipts. Vol. 4, No. 2,3 An Executive Committee was formed consisting of the elected officers and a representative from each of the four standing SCAMIT committees. Organizational activities and budget policies of SCAMIT will be formulated by the Executive Committee and then presented to the members attending the next monthly meeting for adoption. The Notes From the Amphipod Workshop of March 8-11, 1985 are now available and can be obtained by contacting: Tom Parker JWPCP Marine Biology Laboratory 24501 South Figueroa Street Carson, CA 90745 Additional Note : In response to item #4 of the amphipod workshop notes, Dr. Barnard recently sent the following note: "I'm now convinced you have Rhachotro^is inflata , both the small specimen previously identified and the new material. The previous specimen, smaller, has rather poorly developed side crest pleonites 1 and 3 but this is probably a feature of younger specimens. I had a chance to go through all the old figures and original descriptions so I'm well satified you were correct." List of Specimens from June 10, 1985 : HYP 45 Photis brevipes Shoemaker, 1942 HYP 45 Photis californica Stout, 1913 LACO 50 Amphideutopus oculatus Barnard, 1959 LACO 52 Aoroides intermedeus Conlan and .

Karaman are presently working on new keys for the Photidae, Isaeidae, and Corophiidae. Some of the ontogenic problems seen in Photis hopefully will be addressed by this work. MINUTES FROM MAY 13, 1985 SCAMIT Voucher Collection and specimen cards should be turned in to Cathy Crouch as soon as available. The "ID by" line on the specimen label should list the person who identified the specimen for submission to the exchange; or Vol. 4, No. 2,3 the leader of the topic meeting, if the identification was changed during the SCAMIT meeting. Election Results : The recent election to change the constitutional duties of SCAMIT officers was passed by unanimous vote. The duties now stand as: Bylaw 2: Duties of Officers : a) President - The president shall preside at meetings of the Association, represent the Association's interests in external business affairs, present a written yearly summary of the Association 1 s activities to the membership, and perform such other functions as may be defined in the Constitution and Bylaws. b) Vice-President - the Vice-President shall chair ad hoc committees, be responsible for tabulating and disseminating results of elections, votes on Bylaws, Amendments to the Constitution, for specimen exchange, shall arrange the chair for the meeting workshops, coordinate the preparation of voucher sheets, edit voucher sheets and newsletters, and shall perform duties of the President during any period(s) when the President is unable to fulfill his or her * duties as President of the Association. c) Secretary - The Secretary shall keep minutes for all meetings, issue notices for meetings, conduct the correspondence of the association, and be responsible for mailing ballots. Guest Speakers are needed for future meetings. If you have any suggestions for speakers, please see any of the officers at the monthly meetings or send your ideas to: Tom Parker JWPCP Marine Biology Lab 24501 S. Figueroa St. Carson, CA 90745 Ron Velarde Pt. Loma Biology Lab 4077 N. Harbor Dr. San Diego, CA 92101 Changed Meeting Dates : The original meeting dates scheduled for both October and November 1985 have been changed. To avoid conflic with holiday schedules, the new dats for monthly meetings are now October 21 and November 18, 1985. Organizations of Interest : A marine invertebrate taxonomy association has recently been formed on the east coast. Vol. 4, No. 2,3 Titled ESCAMIT, the person to contact for further information is: Nancy K. Mountford Cove Corporation Box 10 Breeden Road Lusby, MD 20657 A Japanese polychaete club has recently been formed concerned with polychaete taxonomy and biology. A newsletter can be obtained by writing to: Dr. Tomayuki Imura Ocean Research Institute University of Tokyo 1-15-1 Minamidai Nakana-ku, Tokyo 164 JAPAN List of Specimens from May 13, 1985 *: SCCWRP 55 Sabellaria cementarium Moore, 1906 AHF 34 Myriowenia californiensis Hartman, 1960 AHF 35 Idanthyrsus ornamentatus Chamberlin, 1919 AHF 36 Cistenides brevicoma (Johnson, 1901) CMM 7 Sabellaria gracilis Hartman, 1944 OCSD 57 Myriochele sp. M Helpful Hints : Leslie Harris pointed out that the outer row of paleae in Sabellaria is an unreliable diagnostic character. The condition and degree of paleal ornamentation is subject to physical wear and dependent upon specimen age. The inner row of paleae is more reliable for species separation (see separate following this issue). Leslie also discussed a potential confusion with the polychaetes Chloeia entypa and Chloeia pinnata . Reexamination of type material shows that the difference in setal types could be size dependent for these worms. Inspection of setae from both anterior and posterior fascicles should be done routinely to determine if C. entypa and C. pinnata setal arrangements are present on the same specimen. Corrections : Don Cadien has sent in the following corrections: "While reexamining distributed specimens in preparation of SCAMIT museum materials, several errors of *Vouchers will be in next month f s issue. Vol. 4, No. 2,3 identification were found. Specimens coded MBC 3, originally identified as Aorides columbiae are in actuality Columbaora cyclocoxa Conlan and Bousefield, 1982. Those coded MBC 6, originally identified as female Microdeutopus schmitti are Aorides spinasus Conlan and Bousfield, 1982. This note consitutes the first published record of either of these species in California. Columbaora cyclocoxa had not been reported south of Meikaw Bay, Washington. The SCAMIT specimens are from drifting kelp holfasts in shallow water 2 miles east of Point Conception. The SCAMIT specimens of Aorides spinosus are from Mission Bay, collected at night with a surface plankton net. Previously, Coos Bay, Oregon was the southern distribution limit of this species." Travels with Olga Abord M/S England (enroute Denmark) 30 August 1939 Dear Folks: Circumstances arising rather hurriedly caused me to change my plans, and I am thus enroute to Stockholm a week earlier than I had anticipated. War clouds have been hanging heavily over Europe the past week, and London, especially, has been so busy "bedding itself in" for times of adversity, that one had little chance of contacting anyone for anything else. Many places are being almost completely dismantled, the treasures stored below and sanded in (with sand bags) or hauled away to places of safety. Even some art glass windows have been removed. One can realize the perilous state only by seeing all of this intense preparation. London would obviously be a choice for air raids, and with its river (The Thames) it is so clearly marked that not even a good "blackout" could hide it. And this time there is no Kaiser Wilhelm (cousin of England's queen) to protect the Parliament Houses or the Royal residences. I went to Liverpool Street Station yesterday morning, INTENDING TO reserve passage to Stockholm for a week hence. The agent stormed at me "What was I doing at this station!" (should have been booking to U.S.A.), and if I had to go to Stockholm it was. today or not at all. Thus, at a minutes notice, I changed plans, knowing I had a lot of last minute things to do before the train's departure at 4 PM. Fortunately, because of the rapid underground system, I was able to shuttle back and forth from one place to another very rapidly, and arrived at the station just in time. Vol. 4, No. 2,3 Now I am on a Danish motorship, the M/S England, enroute from Harwich, England, to Esbjerg, Denmark, and thence via train to Copenhagen. The North Sea has been very calm and beautiful, and last night there was a big, full moon to light up the sea. Today it is cloudy and somewhat chilly, but not unpleasant. It is a very beautiful journey. If war rumors are less disturbing when we dock, I may stop at Copenhagen for several days. If not, I shall go directly to Stockholm where there will be peace and saneness. It is most amazing to see the great amount of travel in these countries (many on consulate's advice)? and to hear the various tongues spoken. Even though I strain my ears to hear and learn, I am greatly bewildered. Danish is a beautiful, softly-spoken language, the consonants light, blending. Swedish is quite similar, but broader. Most of the passengers on board (as are also the entire crew) are Danish, but there are others, including several Americans, recently come over. One goes to Finland, another to Southern Sweden, another to Russia, etc., etc. You see, friendships on board are quickly made (and as quickly dissolved). I asked several of the Americans whether they comprehended the gravity of the Europen sitation when they booked from U.S.A. But unless one stays in Europe a while it is an empty threat. And Americans are typically pioneering. The English pound took a flop a few days ago. I got exchage at $4.35 one day, but could not gain much thereby because the drop came near the close of my stay. The situation of different monies is not as terrifying as I had pictured it. But perhaps I will think different when there is no American Express to which to turn. In London it was very simple. Meals on board are an education. Coffee (and is it strong!) and toast at 8:30 or after, breakfast at eleven, tea at about 4 PM, and dinner at 7 PM. I should have used the twenty-four hour clock, for that is what we use here, but 18:45 instead of 6:45 PM always looks at bit strange to me. Please know, and believe, that I am not in the slightest danger, and even though your papers carry alarming accounts, I hope you will not be disturbed. After all, you know, there are really many more people here than in the U.S.A., and most are sane. Vol. 4, No. 2,3 Notes on the Variation of the Outer Paleae in Sabellaria cementarium Leslie H. Harris MBC, Applied Environmental Sciences, Inc. One of the characteristics that is used to separate the various species of Sabellaria is the shape of the outer paleae. While examining 14 individuals of Sabellaria cementarium collected from a rock in 220 feet off Pismo Beach, the shape of the outer paleae was noted to change with the size of the worm. As the length of the worm increased, the number of teeth of the outer paleae decreased while the pilosity of the arista became denser (see Figure 1 below). This characteristic was consisted for all the outer paleae within each worm. In addition to the outer paleae, the shapes of the middle and inner paleae also were examined. The shape of these paleae remained the same regardless of the size of the individual. Later examination of 45 specimens of Sabellaria cementarium from scattered localities also supported these findings. Therefore, in view of this variability, the shape of the outer paleae should not be used to distinguish between species of Sabellaria. Figure 1. Variaiton of the outer paleae with body size (length in mm) of Sabellaria cementarium . Drawings are not to the same scale. A. 1 mm; B. 3 mm; C. 5-7 ram; D. 7 mm; E. 13 mm; F. 18 mm. Vol. 4, No. 2,3 Emendation of Myriochele gracilis Hartman, 1955 Leslie H. Harris MBC, Applied Environmental Sciences, Inc. Recently I collected what I thought was a new species of Myriochele in some MMS-Santa Maria Basin samples. The specimens had up to 31 setigers with two kinds of notosetae, neurosetae from setigers 3, and uncini with two teeth of equal size (one above the other, both distally curved). Superficially they looked like M. cjxacilis, but M. gracilis was described with 18 setigers, uncini starting from setiger 4, and the uncini with a long basal fang and a shorter distal process (Hartman, 1955) . I examined the holotype and paratypes of M. gracilis at the Allan Hancock Foundation, courtesy of Sue Williams, Assistant Curator. The types had 24-25 setigers, two types of notosetae, uncini starting on setiger 3, and uncini with two equally curved teeth. My examination showed that the original description was incorrect and that my "new" species was really M. gracilis . Hartman’s 1969 diagnosis can be emended as follows: "Diagnosis: Body long, linear, tapers posteriorly (Fig. 1). Length 10-20 mm; width about 0.8 mm* Segments.include 18 to 35 setigers in ovigerous females; noto-setae project laterally in stiff fascicles. Anterior end subglobular to cyclindrical, with appendages. First 3 setigers short, close together, otherwise resemble those farther back have only notoseate in setigers 1 and 2. Multiserial rows of very small uncini from setiger 3 to posterior end (sometimes start on setiger 3 on one side and on setiger 4 on other side). Each uncinus with long stem thick shoulder and distally recurved end, terminating in two teeth of equal length, one above the other (delete Figs. 2 and 3). Notosetae of two kinds, long and spinose, and short with a fine bent tip. The first 2 setigers have notosetae only and the last 2 or so setigers have uncini only. Posterior end tapers to a simple pygidium without appendages. Mature female individuals have large ova through middle two-thirds of body. Tube measures 15-25 mm long by 0.85 mm wide, taper to both ends and externally covered with spicules attached corsswise (Fig. 4), neat in appearance." In the original description Hartman (1955) included specimens that would later be redescribed as Myriowenia californiensis Hartman (1960). She specifically excluded the 1955 illustration of an uncinus from Myriowenia (Hartman, 1960); based on examination of type material I believe it does belong to Myriowenia rather than Myriochele gracilis , as does the statement that the uncini start on setiger 4.

Photis brevipes Shoemaker, 1942 Corophiidae Vol. 4 No, 3 SCAIilT Code: Kyp 45, SCCWRP 57 Date examined: June 10, 1985 Voucher by: Jimmy D. Laughlin Synonymy: Photis californica J.L. Barnard, 1954. Literature: Shoemaker, C.R, 1942, Amphipod crustaceans collected on the Presidential Cruise of 1938. Smithson. Misc. Coll. 101(11):1-52, 17 figs. Barnard, J.L. 1962, Benthic Marine amphipoda of Southern California: 1. Aoroidae, Photidae, Ischyroceridae, Corophiidae, Podoceridae. Pac. Nat. Vol. 3(1). Diagnostic characters: Male gnathopod 2 article 7 stout with the inner edge bearing a large bump and distially a single serration or notch on the inner edge which in young males is a spine, later fused in adults (Fig. 1). Variability: Juvenile males will have an underdeveloped bump on article 7 of gnathopod 2. Figure 1. (after Barnard 1962). Related species and character differences: P* brevipes adult males are most closely related to P. californica. Article 7 of gnathopod 2 is more slender in P_. californica than in brevipes and the small bump on the inner edge of juvenile males of both species decreases in P. californica and increases in size in P. brevipes. The adults of P. brevipes (8mm) are much larger then adults of P. californica (4-5mm) (Barnard, 1962). In P. californica the hind tooth of the palm on gnathopod 2 statrs to gape in terminal adult so that if the dactyl lacks the inner bump the specimen may be identified as P. californica , even though it may have the size of a young P. brevipes (Barnard, 1962). Depth range: 0-183m. Distribution: Coos Bay Oregon to Bahia Magdalena, Baja California. Ecology: This species shows a strong affinity for Diopatra , Listriolobus , Nothria and Amphiodia communities with an average density of 34 individuals per square meter and up to 232 individuals per square meter (Barnard, 1962). Comments: The females of the genus Photis are at the present time indistinguishable. We have decided to leave all females and juveniles with the Photis sp . designation until this problem can be resolved.

Maxilliped outer plate with teeth cusped (Fig. 2). Variability: The number of teeth of the maxilliped outer plate will vary with age (Conlan and Bousfield, 1982). There is also variability in the pigmentation and the dorsal setal bundles of seg. 5 of gnathopod 2 of the males. Figure 1. (after Conlan and Bousefield 1982). Figure 2. Related species: A. intermedius is closely related (intermediate between) to A. columbiae and A. inermis. A_. intermedius differs from A_. columbiae by having the lower teeth of outer maxilliped plate rarely cusped, and dorsum of seg. 5 of male gnathopod 1 with 5-7 bundles of setae, and as broad as seg. 2. It differs from A. inermis by having the upper teeth of outer maxilliped plate cusped, fewer bundles of setae on dorsum of seg. 5 of male gnathopod 1. Depth range: 20 feet to 63 meters. Distribution: Puffin Bay, Baranof Island, Alaska south to Dana Pt. California. Ecology: Boreal, occuring amongst algae and eelgrass on sand and gravel bottoms. Comments: The only sure way to distinguish the females of this species of Aoroides is to look at the teeth on the outer maxilliped plate.

Has pigment bands on ends of art. 1 of ant. 1 and 2, especially when broken off. 4. Usually larger in size than P. brevipes. Figure 1. (after Barnard, 1962). Variability: Male gnathopod 2 varies with developmental stages, from individual to individual. Pigmentation also varies Related species and character differences: P. californica is most closely related to P_. brevipes but differs in lacking the bump on the inner edge of the dactyl, dactyl is more stout than the dactyl of ]?. brevipes . J?* californica typically mature at a smaller size than brevipes. Depth range: Intertidal to 98m. Distribution: y Moss Beach, California, to Bahia de San Cristobal, Baja California. Ecology: Seems to prefer Amphiodia community to Diopatra community where P. brevipes is dominant (Barnard 1969). Comments: The females of the genus Photis are at the present time indistingrishable and we have decided to leave all females and juveniles with the Photis sp. designation until this problem can be resolved.

Additional notes: 1. Cistenides is often considered a subgenus of Pectinaria . (Hartman, 1941.) 2. Some authors (Pettibone 1954, Banse and Hobson 1968, Hobsone and Banse, 1981) regard C. brevicoma as a synonym of C. granulata because of variability in their distinguishing characteristics. 3. Banse and Hobson (1968) found that small specimens may have uncini with their large teeth in two rows as well as in one row. Distribution: Southern California north to western Canada; shallow subtidal to 90 fms; in gravel and sand. Myriochele sp. M Oweniidae S.

Diagnostic characters: (Figure 1) 1. Anterior end with branchial lobes that form a simple notched funnel in juveniles, but increase in complexity with age and become a highly branched, filiform-tipped crown. 2. Conspicuous, thin, membranous collar, uniformly even except for pair of ventrolateral notches. Size of collar depends on size of worm: small juveniles will have only a slight development dorsally while the collar of a large specimen will extend halfway up the branchiae. 3. Uncini with two very long teeth, no shoulder at subdistal end of shaft. Related species and differences: 1. Owena fusiformis delle Chiaje, 1841. Lacks thoracic membranous collar Uncinal teeth short, definite shoulder present. Cosmopolitan; includes records in eastern North Pacific (Hobson and Banse 1981) . Additional notes: Hartman (1955, 1969) specifically distinguishes 0. collaris from 0. fusiformis by the presence of a collar in the former and its absence in the latter. Earlier, (however) Hartman (1945) synonymized 0. aedificator (Andrews, 1891) with 0. fusiformis . 0. aedificator was described as having a delicate membranous collar. Hobson and Banse (1981) illustrate 0. fusiformis with a low but definite collar. Examination of many individuals to determine the extent of variability in collar development, as well as type specimens, is necessary to resolve the questions of synonymy.

Southern California Association of Marine Invertebrate Taxonomists 3720 Stephen White Drive San Pedro, California 90731 July 1985 Vol. 4, No. 4 Next Meeting: Guest Speaker: Specimen Exchange Group: Topic Taxonomic Group: August 12, 1985 Dr. Donald Mauer Director, Southern California Ocean Studies Consortium Scaphopoda, Aplacophora Mytiloidea MINUTES FROM JULY 8, 1985 An Ad Hoc Committee met on June 27th at the Hyperion Biology Laboratory to discuss the formation of an executive committee. this meeting was attended by all officers and a member from each standing committee. A constitutional ammendment defining this committee and its function was sent to the membership for consideration. If approved, the executive committee would serve in an advisory capacity to the officers and be helpful in effectively directing SCAMIT activities and goals in the future. This committee would meet at least annually, with additional data scheduled as needed. The first meeting would be in early August. Funds for this publication provided in part by Chevron U.S.A., Inc. and Arco Foundation Vol. 4, No. 4 SCAMIT receives donation : Many thanks to Texaco for a $2,500 donation which was received July 26th. We would like to also thank Dominic Gregorio for his assistance. SCAMIT has recently sent letters supporting the formation of a National Biological Survey to Dr. Kosztarab (NABIS Planning Chairman), Senator R. Stafford and Ronald Auten (Senate Committe on Environmental and Public Works). These letters described SCAMIT activities and goals, and explained the benefits that SCAMIT would receive from such a survey. Mrs. Bruce Benedict, through Brad Myers, recently donated a large collection of taxonomic literature that belonged to her late husband to SCAMIT. This material includes books, articles and monographs most of which deals mostly with crustacean taxonomy. This generous donation to the growing SCAMIT library is gratefully appreciated. The Western Society of Malacologists has recently announced its 18th annual meeting. The meeting will be held at the Santa Rosa Residence Hall of the University of California at Santa Barbara on August 18-21, 1985. Sessions on Hawaiian Mollusks, Gulf of California Mollusks, Opistobranchs, land snails. Paleontology, and a other general Molluscan topics will be presented. In addition, a fossil field trip, a dredging trip, and a cruise to Santa Cruz Island are scheduled. A fund raising auction will also be conducted offering fine molluscan specimens, books, and reprints will be up for bidding. The pre-registration fee is $15.00 for regular members and $7.50 for student members.

D (MBC) are very similar and may not be distinct enough for species separation. Leptognathia sp. B possesses distinct curved uniramous uropods. Both the body and uropods are heavily calcified. Leptognathia sp. C has a pair of lateral pleonal teeth pointing ventrally, while Leptognathia sp. E has a single sternal tooth extending posteriorly to the end of the telson. Don Cadien and Carol Paquette of MBC, Applied Environmental Sciences have provided the following information on Tanaids: The crustacean order Tanaidacea encompasses nearly 800 recent species of which 50 morphotypes have been identified from California. Systematics among Californian species is very difficult. Presently many new species have been collected during recent environmental studies (e.g., MMS surveys in the Santa Maria Basin) and need to be described. Tanaids are common on both soft and hard substrata from intertidal to abyssal depths. In shallow waters, the intertidal and sublittoral rock habitats are dominated by Zeuxo normani (= Anatanais normani), especially in coralline algal mats. Other common shallow hard substrata tanaids are Synapseudes intumesceus , Pagurapseudes laevis , and Parapseudes latifrons . In bay muds various species of Leptochelia and some Leptognathia commonly occur. In deeper offshore waters, common tanaids on hard bottom habitats include Zeuxo paranormani , Anatanais pseudonormani , Tanaidacea sp. A and sp. B [of MBC), and Apseudes sp. A (also of MBC). Various species of Leptognathia dominate deeper soft bottom habitats with species of Cryptocope also occurring. The best characters to use for speciation in this group are: 1) number of pleonal segments; 2) number of uropod inner-ramal segments; 3) presence or absence of eyes; 4) stoutness of pereopods 1-7; 5) sternal and lateral teeth; 6) placement of uropods; and 7) structure of uropod (biramous vs. uniramous). Characters generaly not found to be useful were size and shape of the gnathopod, shape of the head, and Vol. 4, No. 4 width of the body. These characters seem to be dependent on sexual differences and vary with age of the animal. These will probably be more useful once life histories of California species are known. Travels with Olga (Postcard) Malmo, Sweden 31 August 1939 Dear Frieda: I have left London rather hastily, because of the acute condition of events, and have had a beautiful and quiet trip thus far. Crossed the North Sea, Denmark and Kattegat, now very safe and sane. My greatest difficulty right now is language! But I will get on. (Another postcard) Malmo, Sweden 31 August 1939 Dear Folks: Arrived in Sweden, going direct to Stockholm. European situation looks foggy, hence my hurried departure from London. Hope you do not feel concerned. Everything is safe and sane here. More later after I arrive in Stockholm. Everything has been beautiful and interesting thus far.

Myriowenia californiensis (from Hartman, 1955) Owenia collaris Hartman, 1955 Owertiidae Vol 4, No. 2,3 SCAMIT Code: CMM 8 Date examined: 13 May 1985 Voucher by: Leslie Harris Synonymy: Owenia fusiformis collaris Hartman, 1955 Literature: Hartman, 1955; 1969; Hobson and Banse, 1981. Diagnostic characters: (Figure 1) 1. Anterior end with branchial lobes that form a simple notched funnel in juveniles, but increase in complexity with age and become a highly branched, filiform-tipped crown. 2. Conspicuous, thin, membranous collar, uniformly even except for pair of ventrolateral notches. Size of collar depends on size of worm: small juveniles will have only a slight development dorsally while the collar of a large specimen will extend halfway up the branchiae. 3. Uncini with two very long teeth, no shoulder at subdistal end of shaft. Related species and differences: 1. Owena fusiformis delle Chiaje, 1841. Lacks thoracic membranous collar Uncinal teeth short, definite shoulder present. Cosmopolitan; includes records in eastern North Pacific (Hobson and Banse 1981) . Additional notes: Hartman (1955, 1969) specifically distinguishes 0. collaris from 0. fusiformis by the presence of a collar in the former and its absence in the latter. Earlier, (however) Hartman (1945) synonymized 0. aedificator (Andrews, 1891) with 0. fusiformis . 0. aedificator was described as having a delicate membranous collar. Hobson and Banse (1981) illustrate 0. fusiformis with a low but definite collar. Examination of many individuals to determine the extent of variability in collar development, as well as type specimens, is necessary to resolve the questions of synonymy. Distribution: Southern California, shelf through canyon depths; in mixed sediments with mud and silt. Idanthyrsus ornamentatus Chamberlin, 1919 Sabellariidae Vol. 4, No. 2,3 SCAMIT Code: AHF 35 Date examined: 13 May 1985 Voucher by: Leslie Harris Literature: Chamberlin, 1919; Hartman 1944; 1948; 1969; Banse, Hobson and Nichols, 1968?

Thoracic paleae distally widened (paddle-like). South America; Puget Sound (Hobson and Banse, 1981). Additional notes: 1. Some authors (Okuda, 1938; Pettibone, 1954) synonymize I. armatus and 1^. ornamentatus , others (Hartman 1944, T941TJ 1969; Banse et al. 1968; Hobson and Banse, 1981) consider them both valid species. 2. The shape of the thoracic paleae is considered a more reliable species character than the shape of the outer paleae (Hobson and Banse, 1981? Banse et al., 1968). Distribution: Northern California thorugh Alaska? intertidal rocky habitats? reef-building.

Southern California Association of Marine Invertebrate Taxonomists 3720 Stephen White Drive San Pedro, California 90731 August 1985 Vol. 4, No. 5 Next Meeting: Guest Speaker: Specimen Exchange Group: Topic Taxonomic Group: September 9, 1985 Jay Shrake, Marine Ecological Consultants Ampharetidae Scaphopoda, Aplacophora MINUTES FROM AUGUST 11, 1985 Guest speaker - Dr. Don Mauer from the Southern California Ocean Studies Consortium presented a review of SCOSC's activities and goals. The Consortium coordinates teaching and research of ocean studies from the six California State Universities in the Los Angeles area. These schools, Dominguez Hills, Fullerton, Los Angeles, Long Beach, Northridge, and Pomona represent 40 percent of the CSU system student body. Using its boat, the R/V Nautilus, the consortium has provided training and research experience for over 19,000 students. These students represent 14 different CSU departments. In part, this training has helped about 80 percent of the graduates to actively continue in science. The work of the Consortium has focused on environmental impacts of coastal and harbor influences. This requires an Funds for this publication provided in part by Chevron U.S.A., Inc., Arco Foundation, and Texaco, Inc. - 1 - approach which is multidisciplinary and results in applied "hands-on" experience for students. Much of the work has been done under grant or contract to the Bureau of Land Management and the Ports of Long Beach and Los Angeles. Together with other fundng, the work has provided for preparation of an inventory of local coastal marine biological and oceanographic data. For the future, given its strong faculty and student participation, the Consortium is presently seeking to acquire facilities for a shore-based laboratory and to upgrade field work by replacement of the R/V Nautilus. Also in the future, on May 2nd and 3rd of 1986, the Consortium will be conducting the Sixth Mexico-United States Marine Symposium. This will be held as part of the Southern California Academy of Sciences annual meeting at Cal State San Bernadino. Susan J. Williams has recently received copies of her paper titled: "The status of Terebellides stroemi (Polychaeta; Trichobranchidae) as a cosmopolitan species, based on a worldwide morphological survey, including description of new species." Originally read at the First International Polychaete Conference, Sydney, Australia; a copy can be obtained by writing to Susan at the Allan Hancock Foundation, University of Southern California, Los Angeles, California 90089-0371. Reminder : Due to conflicts with holiday schedules the October and November meeting dates have been changed to October 21 and November 18. Helpful Hints on Mytiloida identification were provided by Paul Scott of the Santa Barbara Museum of Natural History. The genus Crenella is highly variable with bifurcating ribs common and sculpture interspaces both narrow and wide. The polymorphism seems to be overlapping in C. divaricata and C. decussata. The variation in the hinge of these two species does not provide a consistent character of common separation. After examining the exchange specimens, SCAMIT has decided to recognize the priority of Crenella decussata in southern California. Small Megacrenella Columbiana are often separated from Crenella spp. by recognizing the larger protisconch ("larval shell"). Both Modiolus rectus and Modiolus neglectus have been identified as adults in southern California. Individuals below 35 mm in length are commonly given species identification, but should not be due to the inconsistent display of characters necessary for distinction. As a - 2 - convention, those individuals below 35 mm will be considered juveniles. Many of the juveniles may be recently settled larvae that never establish as adults and do not represent an accurate component of the fauna. A helpful aid to identification of juveniles would be a collection of size series.

The statements about Chloeia entypa Chamberlin 1919 and Chloeia pinnata Moore 1911 in Vol. 4, No. 2-3 were incorrect. What Leslie Harris discussed was not a potential confusion, but a resolution of the existing problem. The bifurcate notosetae are supposed to be either smooth or with basally-directed serrations on the outer side of the main fang. The serrations on pinnata are supposed to be only on the inner side of the main fang and distally directed. Chloeia s found in southern California have only the distally-directed serrated notosetae when they are less than 5 mm in length; as they increase in size, the notosetae with basally-directed serrations begin to appear posteriorly. Large individuals have the " pinnata -type" setae in the anterior 2/3's to 1/2 of their bodies and " entypa -type" setae in the remaining 1/2 to 1/3. Examination of the holotype and the paratype series of C. pinnata , all large (>20 mm), revealed they had both kinds of serrated setae. Chamberlin's holotype of entypa had badly deteriorated setae which could not be used for determination of their structure, but in other characters it fit well within the range shown by populations of C. pinnata . In light of this, all southern California speciemens can be assumed to be C. pinnata . 2. The figures of Sabellaria palae have been mislabeled. A and B represent paleae typical of specimens between 13 and 18 mm in length, C is from a 7 mm long worm, D was found in 5-7 mm worms, E from a 3 mm worm, and F from a 1 mm worm. Travels with Olga Naturhistoriska Riksmuseum Stockholm 50, Sweden 1 September 1939 Dear Albert: I found your letter, with that of Mothers, awaiting me when I arrived here yesterday. Many thanks. I was sorry to have had to push up my trip a week, but there was no choice. Now I wish I had brought all my baggage with me. The bulk of it is persumably either still in London, or better, I hope, on a Swedish steamer enroute here. The steamship company here is unable to give out any information. Sweden is a very beautiful country. There are many clear lakes, much greeness, and beautiful trees abound. I came by train from Malmo, S.W. end, to Stockholm; the journey from Copenhagen required a full day, but it was very interesting in many ways, largely because the cities are totally unlike. London is the greatest metropolis in the world, and depicts a cross section of life from every corner of the world. They all count England as their home. Everyone speaks at least some English, but there are many tongues spoken. Stockholm is distinctly Swedish, and now, perhaps, more than usual because of the European turmoil. My greatest difficulty is language . Since I find only an occassional person who can speak a little English or German, I have no choice but to learn Sweidsh. I live in a pension (pronounced pac-y-on) where only Swedish is spoken and understood. The first few hours were agonized for me. I could not make known my most urgent needs. But gradually it is coming. I had previously learned to read it slightly but also Danish, and the two, though similar, are different. Then too, reading it and hearing it spoken are two different things. Some of the commonest words have no homologies in any language, so far as I know, hance ni is you, men is but, inte is not, (in Danish it is ikke), 1jus Ts light, etc., etc. Menus are a bug-bear for me. Sometimes I point a finger at anything and trust to luck that it is something suitable. But yesterday evening, when I asked for "soppe" (soup), smor och brod och kaffee, I got also ost (cheese), sill (herring) and different kinds of breads. Menus in London often had me guessing, but here I am totally confounded. Just came in from the streets and saw the sad headlines of the European turmoil. Everyone hopes it will blow over, but no one believes it. All of Europe is heavily armed, and defenses are rigid. At any rate, Scandinavia remains neutral. Not one dares to make predictions. I should like to write you more of the life here, and this wonderful Sweden, not only of the broad general principles, such as the operation of the famous Cooperative System, and prevention of poverty, but even down to details such as the rooms we live in, the people that occupy them, what we eat for our meals (they are very different from those in London); the speech, the money system; control of traffic (as in England, Sweden has left hand traffic and is the only country in contenental Europe that retains it. It is shortly to be changed to right-handed.) But time forbids now. Most of my spare hours are being taken up trying to learn the language, and acquainting myself with my enviroments. Best wishes to you all. - 4 - 1984-1985 Membership Renewal Application It is time to begin renewing memberships. SCAMIT is beginning its third year in April. You may begin renewing now.

Systematics of "Ampharetid Polychaetes" Place: Cabrillo Marine Museum 3720 Stephen White Drive San Pedro, Ca. 90731 Specimen Exchange Group: Terebellidae Topic Taxonomic Group: Ampharetidae MINUTES FROM SEPTEMBER 9, 1985 Guest speaker - Jay Shrake from Marine Ecological Consultants gave a presentation on the local Caudofoveata (Chaetodermatida and Solenogastres Aplacophora). Impor¬ tant taxonomic characters include spicule morphology, structure of the radula, and the relative shape and size of each body region. The body is divided into four regions (A thru D). The anterior end containing the radula is Region A and the posterior end containing the gills is Region D. Spicule morphology is best examined by placing a portion of each body region in a well slide with some bleach. This frees the spicules from the body wall without destroying their shape. The spicules should only be left in the bleach solution for a short period of time; afterwhich they should be rinsed in water so they do not completely dissolve. The well slide also provides an area where the three dimensional structure of the spicule can accurately be examined. The radula and chitonous support membranes must be dissected out to permit adequate examination. Methylene blue can be used to stain the radula to determine the shape of the support material. Differentiation between the two common genera Chaetoderma and Falcidens can best be determined by the radulat differences. Additionally Falcidens usually has a short body Region B, while the Chaetoderma body Region B is longer. Many of the species described by Schwabel (1963) will ultimately be discarded due to poor descriptions and lost type material. Additional synonymies for some species described by Heath (1911) may occur in a forth-coming publication.

Diagnostic characters: 1. Shell small, less than 4 mm. 2. Shell sub-ovate, moderately inflated. 3. External sculpture of fine thick radial lines crossed by concentric striae, giving a beaded appearence in some specimens. 4. Internal margins crenulate. 5. Hinge plate directly below beaks, striated, well developed to obscure. Additional notes: 1. The eastern Pacific Crenella are in need of a thorough systematic revision. Comparing specimens from Alaska, Washington, Oregon, California, and Mexico yielded no consistant differences between specimens. The conchological differences between C. decussata and £. divaricata as outlined by Soot-Ryen (1955) are unworkable when one compares northern specimens with the southern specimens. At this point it is advisable to treat the southern California Crenella as one species, rather than to retain two species which are indistin¬ guishable. By systematic priority, Crenella decussata should be used as the southern California species. Depth range: 5-460 m (Bernard, 1983) Distribution: 60N to 2S (southern range as C. divaricata; Bernard, 1983) See illustrations on reverse side Crenella decussata (Montagu, 1808) Drawing by Laurie Marx, Santa Barbara Museum of Natural History Megacrenella Columbiana (Dall f 1897) Mytilidae SCAMIT Vol. 4, No. 6 SCAMIT Codes: LACO 54, SCCWRP 59 Date examined: 12 August 1985 Voucher by: Paul Scott (SBMNH) Synonymy: Crenella Columbiana Dali, 1897 Crenella rotundata Dali, 1916 Crenella tamurai Habe, 1955 Literature: Soot-Ryen, 1955; Oldroyd, 1924; Dali, 1897 Diagnostic characters: 1. Shell small, less than 20 mm. 2. Shell thin, highly inflated, subquadrate to ovate. 3. External sculpture of fine radial ribs. 4. Hinge obsolete in adults, juveniles with weak, striated hinge plates. Additional notes: 1. This species is easily separated from Crenella decussata by the large thin shell and the very fine radial ribs. 2. Juveniles can be separated from Crenella by the large prodissoconch and the fragile, thin shell.

Shell elongate, inflated, beaks sub-terminal. 2. Shell without definite external sculpture, but with growth striae. 3. Hinge without teeth. Additional notes: 1. Several species of Modiolus are present in the intertidal and continental shelf of southern California. Juveniles of the genus are extremely difficult, if not impossible, to separate. The leadino authority on Modiolus does not feel juveniles can be identified to the species level if they are less than 35 mm in length (B. Wilson, pers. corns. 1984). Until a complete size series (juvenile to adult) for each species is assembled, it seems best to report our juveniles as Modiolus spp. juvenile.

He spoke about his participation with Captain Hancock and the Galapagos expedi¬ tions aboard the Velero III. This ship was 195 feet long, 31 feet wide at the beam and cruised at 13.5 knots. It had adequate fuel and water for each cruise to last two to three months with a minimum of port calls. Thirty-two people could be accomodated on board. Of these, usually fourteen were in the captains party and were provided private staterooms with bath. Also onboard were a photographer, chief operations officer, and a physician. The visiting scien¬ tists included individuals from major zoos, aquaria, and museums. In later cruises, many graduate students from U.S.C. participated. The Velero III had five 60 gallon aquaria for maintenance of live aquatic specimens. Two 26 foot launches and three 13 foot skiffs were available for shoreward excursions and landings. Though busily collecting specimens pertaining to their interests on each cruise, the scientists had considerable exposure to entertainment. Each evening a trio of musicians would give a one hour concert. Captain Hancock played the cello, Dr. Garth played the grand piano, with a third usually playing the flute or violin. Music for these concerts commonly included selections from the composers Mozart, Haydn, and Liszt. Additional comfort was provided by an extensive cache of ice cream and regular use of Captain Funds for this publication provided in part by Chevron U.S.A., Inc., Arco Foundation, and Texaco, Inc. - 1 - Hancock's own salad dressing. Much of the details for the scientific collecting during these expeditions are available, with photographs, in the Allan Hancock Foundation Pacific Expeditions, Volumes I, II, and III.

By using substage lighting, one can instantly determine the live ones from the empty shells. This method works will with stations with a large number of Spiophanes miss - ionensis . Instead of splitting each tube in half and hoping not to damage the worm, the substage lighting lets you trim off the excess tube and leave the worm completely intact for the identifier. The above method is also helpful to sort Turbonilla , Myriochele , and Onuphis , or any organism which retracts into a thin shell or thin-walled tube.

A study site was established around the L.A. County Sanitation Districts outfall. Influences on the oceanographic conditions at the 4 km by 10 km site include natural upwelling of nutrient rich seawater and diffusion of sewage effluent. Data was collected by monitoring weather and treatment plant conditions, as well as using shipboard and moored instru¬ ments to record water temperature, ocean currents, wind speeds, ammonia concen¬ trations, bacteriological counts and productivity, and chlorophyll levels. Use of this information assists in predicting the distribution of the outfall's effluent plume. It is clear from this study that the spread of the effluent plume is unequally distributed in a manner that permits 1% of the plume to extend 2 km in 3 hours and that within 6 hours 1% of the plume will extend beyond the boundary of the study area. In concluding. Dr. Jones explained that predicting an effluent plume distribution is not as certain as hoped due to the influences of semi-diurnal changes and tidal fluxes. Good descriptions of oceanographic conditions also require a rapid (less than 10 hours) sampling of the study area. It was.also found from this study that ammonia concent rations provide a reliable tracer of effluent plume movement. Additional correlations between bacteriological counts, productivity and ammonia levels can improve prediction of effluent plume distribution Funds for this publication provided in part by Chevron U.S.A., Inc., Arco Foundation, and Texaco, Inc. - 1 - Vol. 4, NO. 8 Christmas special .

Susan J. Williams Allan Hancock Foundation These two species are found in shelf depths (2n0m or less) and can co-occur. They may be separated on the basis of the branchiae, structure of the lower lip, and methyl green staining pattern. Both species have 16 thoracic setigers plus small palae and 13 thoracic uncingers; 4 pairs branchiae. I. Lysippe A (commonly accepted as L. labiata ) 1. Branchiae moderately thick, textured, and with a few dark cross-bars. 2. Prostomium clearly trilobed, with middle portion extended a bit beyond the lateral margins. 3. Lower lip broad, with faint crenulations; anterior margin of lip squared off (fig. 1) 4. Methyl green staining: a. On uncinger 8, a conspicuous presetal narrow white band evident immediately after staining. b. Typical ventral pattern per segment: narrow dark band, narrow light band, broad medium-dark band (fig. 2), c. Torus does not stain. d. After sitting in 70% ethanol for a while, the stain remains darkest at uncingers 3 and 4. e. Ventrally, stains through 11 setigers Figure 1 Figure 2 Lysippe SCRMIT Vol. 4, No.8 II. Lysippe B (undescribed) 1* Branchiae slender, textured, with many white cross-bars. 2. Prostomium more obscurely trilobed, with median part fairly flush with lateral margins or barely projecting. 3. Lower lip obviously crenulated, with well-defined rounded projections on the anterior margin (fig. 3). 4. Methyl green staining: a. Uncinal tori usually with postsetal patch of green dots. b. Typical ventral pattern per segment: broad light band, thin dark band, broad medium-dark band. c. Ventrally, stains for 10 setigers, then stops abruptly. Figure 3 Ampharete acutifrons (Grube, 1860) Ampharetidae SCAMIT Vol. 4, No. 8 SCAMIT Code: LACO 59 Date Examined: October 16, 1985 Voucher by: Susan Williams (AHF) Literature: Banse, 1979 Hartman, 1969 Uschakov, 1955 Diagnostic Characters: 1. Thoracic setigers number 14 plus palae; 12 thoracic uncinigers. 2. Palae conspicuous, number 15-25 pairs; in larger specimens these form nearly complete circles. 3. Branchiae 4 pairs, arranges in 3 anterior and 1 posterior pair; the two groups well-separated. 4. Some abdominal tori with a long cirrus at the superior end (figure 1). 5. Abdomen with 12 setigers; pygidium surrounded by a circlet of several long cirri. Related Species and Differences: Ampharete arctica : Pygidium with 2 lateral cirri. Ampharete goesi : Abdomen with 17 setigers. Ampharete labrops : Upper lip with numerous minute eyespots along ventral edge. Additonal Remarks: Specimens fit the accepted North Pacific definition of Ampharete acutifrons . The species was first dexcribed from Greenland and there are discrepancies in the literature as regards the nature of the palae and abdominal toral cirri between the Atlantic and Pacific forms. Distribution: Arctic to western Mexico in shelf and slope depths. Figure 1 {from Hartman, 1969) Anobothrus gracilis (Malmgren, 1866) Ampharetidae SCAMIT Vol. 4, No. 8 SCAMIT Code: LACO 60, PL 60, SCCWRP 63, MBC 36 (as A. bimaculatus) Date Examined: October 16, 1985 Voucher By: Susan Williams (AHF) Literature: Fauchald, 1972 Hartman, 1969 Williams, in press Diagnostic Characters: (Pacific specimens) 1. Palae present, moderately developed. 2. Thoracic setigers number 15 in addition to the palae. NOTE: first post- paleal notosetae very small, easily overlooked. 12 thoracic uncingers. 3. Notopodia of setiger 11 (uncinger 8) slightly elevated (figure 1) and the notosetae modified, being distally minutely hirsute (figure 2). A glandular band connects the notopodia of this segment and is especially evident after staining with methyl green. A less developed glandular band is found on setiger 6. 4. Branchiae 4 pairs, arranged in 3 anterior and 1 posterior pair. Related Species and Differences: Anobothrus occidentalis : actually Sosane (Williams, in press) Anobothrus trilobatus : actually Eclysippe (Williams, in press) Anobothrus bimaculatus and A. mancus : Deep-water species. At this point, these species are difficult to distinguish from the shallow water A. gracilis . Methyl green staining patterns show only subtle differences. Also, there are errors and discrepancies in the original descriptions. Additional Remarks: 1. Anobothrus is easily misidentified as Ampharete arctica , due to the fairly subtle elevation of notopodia 11. By staining the specimens in a methyl green solution, the characteristic glandular band between the notopodia of that segment becomes obvious, 2. There are some errors in the diagnosis of species in Hartman's Atlas: thoracic uncingers number 12, not 13; notopodia of setiger 11, not 13 are slightly elevated. Also, the generic key to the Ampharetidae is in error. The couplet with Anobothrus states notopodia of setiger 8 modi¬ fied; this should read 'uncinger 8'. 3. The California species is probably distinct from the Atlantic A. gracilis , but until a generic review is done, it would probably be best to continue using the name. Distribution: California, in shelf depths. Anobothrus gracilis (Malmgren, 1866) Ampharetidae SCAMIT Vol. 4, No. 8 Figure 1 (from Williams, in press) Figure 2 (from Hartman, 1969) SCAMIT Vol. 4, No. 8 Anobothxus trilobatus Hartman, 1969 Ampharetidae SCAMIT Code: AHF 39 Date Examined: October 16, 1985 Voucher By: Susan Williams (AHF) Literature: Eliason, 1955 Hartman, 1969 Williams, in press Diagnostic Characters: 1. Prostomium broadly rounded, divided by a transverse furrow behind which are 2 pigment patched (Figure 1). 2. Lower lip faintly crenulated. 3. Palae moderately developed. 4. Thorax with 15 setigers in addition to the palae? posterior thoracic segments (setigers 11-15) elongated, with trilobed notopodia in well- preserved specimens (Figure 2). 5. Branchiae 3 pairs, inserted in a straight line and separated by a wide interbranchial pad (Figure 1). Additional Remarks: This species belongs to Eclysippe Eliason, 1955 on the basis of number of branchiae and the absence of Anobothrus (sensu strictu) notopodia (Williams, in press). The California species may be separated from the European E^. vanelli on the basis of degree of development of the first notosetae and methyl green staining pattern.

Anterior thoracic segments fused, with fine needle-like spines in first 4 neuropodia (Figure 2). In all, 18 thoracic setigers. 2. Notosetae obvious from setiger 4; Fauchald (1972) mentions a small fascicle at setiger 3* 3. Dorsal postbranchial transverse membrane present, with 11-16 dentitions (Figure 1). 4. Nuchal hooks present; these gently curved. 5. Branchiae 4 pairs; long, subulate and often with a greenish hue. Related Species and Differences: Melinna denticulata : 17 thoracic setigers; transverse membrane with 7-9 teeth. Melinna elizabethae : Nuchal hooks strongly curved; transverse membrane with small dentitions. Melinna oculata : Branchiae short, digitiform, corss-barred with dark and light bands; nuchal hooks strongly curved; transverse membrane with about 10 'rounded' dentitions. Distribution: Central California to western Mexico, in canyon and slope depths.

Palae present, of unusual form, being distally oblique (Figure 2). 2. Thorax with 15 setigers in addition to the palae; first notosetal fascicle minute, easily overlooked. Thoracic uncingers number 12. 3. Branchiae 3 pairs, inserted in a transverse row. 4. Smooth dorsal ridge at setiger 3 (Figure 1). Related Species and Differences: Melinnampharete eoa - see below. Additional Remarks: 1. Hartman (1969) erroneously described M. gracilis with 14 thoracic setigers plus palae. Examination of the type material revealed a small fascicle of fine setae immediately following the palae. 2. This species will key to Eusamythella (Hartman, 1967) using Fauchald, 1977. The distinction between Eusamythella and Melinnampharete is based on number of thoracic setigers (15 vs 14). However, this is invalid, as Melinnampha¬ rete is described with 15, in addition to the palae (Annenkova, 1937). There are no appreciable differences between the two genera and they are most likely synonomous. 3. It is also quite likely that M^. eoa Annenkova and M_. gracilis Hartman are identical. Hartman (1969) states that M. eoa differs from PI. gracilis in having 17 thoracic setigers, instead of 14. However, both species have 15 thoracic setigers (plus palae)? Annenkova describes 17 thoracic segments , of which 15 bear notosetae. Also, Annenkova notes that 'The dorsal podial process of the third segment are hardly noticeable'. This fits with the situation, in P^. gracilis . Pending publication of the synonomy, Melinnam ¬ pharete gracilis should be used for California specimens. Distribution: Minimall, California to western Mexico, in basin depths.

Pettibone, 1954; Moore, 1923; Hartman, 1963. Diagnostic characters: All setae simple; neurosetae acicular, distally pointed with the tip drawn out as a slender filament. Branchial membrane short, rounded, with 60-70 pairs of branchiae. Notosetae of first setiger project forward, appear to be a sparse cephalic cage. Dorsal papi¬ llae broadly tubercular, terminating in filiform tip, arranged in 4-5 longitudinal rows; ventral papillae the same but smaller. Neu¬ ropodia of only 1-2 long, tiny, slender papillae. Nephridial papi¬ llae on fifth setiger, on ventrum. Bumpy appearance, greyish yel¬ low to gold in color. When contracted the segments are very tight¬ ly folded together, so what appears to be 1 segement with 8-10 or more large dorsal papillae is actually 2 or 3 segments. Related species and character differences: Brada sachalina Annenkova, 1922 also has large tuberculate papi¬ llae with filiform tip, but only in 2-3 transverse rows in median segments, also only 21-22 segments. Fig. 1 Ventral papilla, X50 Fig. 3 Notopodial papilla, X1200 Fig. 1,2, 3 from Hartman, 1969 Brada pluribranchiata (Moore, 1923) SCAMIT Vol. 4, NO. 8 Distribution: Hartman, 1969: Southern California, in deep slopes and canyons, in 123-1400m; in black sand and mud. Hartman, 1963: Monterey Canyon through Catalina Canyon, 88-431m. Fauchald, 1972: Southern California in deep slope and canyon depths; present records are from similar depths off Cedros Island, Baja California. Comments: This species was synonymized with 5. villosa by Pettibone (1954) along with several others on the basis of extreme variability in the amount of papillae and sand incrustation. In the original description Moore says: "Parapodia con¬ sist of small flat notopodial and neuro- podial papillae, the former about three times the diameter and height of the latter, placed close together on the sides of the segments." Specimens seen have the opposite arrangement-small notopodia and large notopoaia.

Diagnostic characters: All setae simple; neurosetae acicular, distally curved. Branchial membrane short, rounded, with about 30 pairs of branchiae. Cepha¬ lic cage absent, although notosetae of first setiger are elongate and project anteriorly. Body covered with filiform papillae, 8-12 rows in dispersed arrangement. Dorsal papillae with long, slender, filiform tip, or often with terminal enlargement. Most encrusted with sand at the base. A pair of nephridial papillae on ventrum of setiger 5, near the parapodia. Segments about 31-33 in number. Long slender papillae surrounding parapodia; forming a rosette. Grey color, fuzzy overall appearance. Sometimes the skin is in¬ flated and translucent. Related species and character differences: B. inhabilis (Rathke, 1843) has numerous dermal papillae that are elongate and conical with short tapering tips, and 22-26 segments. B. pluribranchiata (Moore, 1923) has fewer, larger broadly tuber¬ cular papillae with short filiform tip.

Flabelligera hearens Chamberlin, 1919. Literature: Hartman, 1969 Light, 1978; Moore, 1909; Hartman, 1961; Spies, 1977. Diagnostic Characters: Neurosetae of all setigers except the first, compound or pseudocom¬ pound falcigers. Rudimentary mucilaginous sheath on dorsolateral surfaces. All papillae long, pedunculate, with clavate tips, not incrusted with sand or silt. Cephalic cage present. Color in life: Adults reddish purple, ventrum dull orange yellow with green tinge, juveniles grey or light greenish-brown. Variability: Neuropodia may have 2 compound falcigers instead of one. Related species and character differences: F, infundibularis Johnson, 1901 has a very thick mucus sheath in which the bulbous tipped capillae are embedded. The papillae are translucent, unlike the obvious grey (preserved color) papillae in F. commensalis . Fig. 1 Entire Flabelligera commensalis , mucous sheath rudimentary (Hartman, 1969) Flabelligera commensalis (Moore, 1909) SCAMTT Vol.4, No. 8 Distribution: Central and Southern California, intertidal to shelf depths. Ecology: Most commonly found on Strongylocen - trotus purpuratus and S. franciscanus , also on Centrostephanus coronatus, on other sea urchins and some polychaetes. Free-living in kelp holdfasts and on rocky and mixed bottoms. 11 ...uses its palps to feed on the faecal matter of its host, it will also employ its own respiratory current for feeding on loose detritus (Spies, 1975)". -Fauchald and Jumars, 1979 Comments: The illustrations of the whole animal in Hartman 1961 and 1969 are deceptive because they make the worm appear flat¬ tened and oval in cross-section, with very obvious cross papillation. In most preserved animals the papillation is minute and indistinguishable against the overall grey color, while the papillae of the notapodia is appressed to the body. The dorsum is flat and the neuropodia are situated ventrally, widely spaced from the notopodia.

Diagnostic characters: Prominent cephalic cage, 4 pairs of thick branchiae, 2 pairs of much smaller lateral processes. Body uniformly and densely papillated, papillae small and closely packed. Cross striations of median region of cephalic setae widely spaced, much longer than wide. Related species and character differences: P. papillata (Johnson,1901) has large papillae, well separated from each other; the cross striations of cephalic setae are barely longer than wide in median regions; 4 pairs of branchiae; generally found in rocky sediments. P. inflata (Treadwell, 1914) has a single row of small papillae per segment; there are 4-6 pairs of large branchiae and 12-13 pairs of much smaller branchiae; anterior end obliquely truncate; occurs intertidally in rocky areas. P. negli - gens (Berkeley and Berkeley, 1950) has neurosetae that tend to be twisted and pseudocompound, and the unidentate tips are enclosed by a indistinct hood. P. plumosa (Miiller, 1776) apparently shares the same characteristics as P. papillata , and Pettibone (1956) synony- mizes them. Hobson and Banse (1981) follows this synonymy.

Important characters: T-shaped prostomium, lack of anterior acicular spines, branched gills on setigers 2-5 and prominent dorsal and ventral cirri in posterior parapodia. Overall appearance very distinctive. Preser¬ ved color rusty to bright orange. Related species and character differences: The genus Scalibregma is monotypic. However the genus Sclerobregma Hartman is closely related, differing mainly in the presence of acicular spines in anterior setigers. Sclerobregma may occur off western Mexico (see "comments’' for further discussion).

Scalibregma inflatum may also feed at the surface.” Fauchald and Jamars, 1979 Comments: Specimens from western Mexico reported by Fauchald (1972) have short, slender acicular spines in each of the first parapodia. Kudenov and Blake (1978) noted that the specimens should be re¬ examined because the spines are charac¬ teristic of Sclerobregma .

Marine Invertebrate Taxonomists Designed, written and illustrated by Philip Chang \j\N • SQ(j Southern California Association of Marine Invertebrate Taxonomists 3720 Stephen White Drive San Pedro, California 90731 December 1985 Vo. 4, No. 9 Next Meeting: January 13, 1985 Guest Speaker: Dr. Richard Brusca, Curator L.A. County Museum of Natural History Specimen Exchange Group: "Clidistics". Cumacea Topic Taxomomic Group: Oligochaeta MINUTES FROM December 9, 1985 Guest Speaker, Dr. Bruce Thompson, gave a review of the Phyla Sipuncula and Echiura. He distributed a packet containing checklists of Southern California species, dichotomous keys to species, literature references, and anatomical drawings. Accurate identification of an Echiuran or Sipunculan requires a good dissection to permit inspection of several diagnostic characters. For the Sipuncula, the animal should be placed with the ventral side up in a wax pinning dish with adequate alcohol to cover the specimen. Using fine iridectomy scissors, a longitudinal cut is made from the tip of the introvert to the posterior end. This incision runs along the lateral margin nearest the wax pinning surface. With several accessory cuts across the body, flaps of integument may be lifted back and pinned to reveal the internal structures. Important characters to note are the arrangement of oral tentacles and hooks on the introvert. Also, note the shape and number of nephridia, retractor muscles and whether any villi are attached to the contractile vessel. For specimens that are too small for dissection (e.g.. Golfingia minuta), internal structures will be best seen using a compound microscope with the animal firmly flattened on a slide. Funds for the publication provided in part by Chevron U.S.A. Inc., Arco Foundation, and Texaco Inc. - 1 - Vol. 4, No. 9 Echiurans should be examined externally prior to dissection. Possession of setae on the posterior end, prostomial shape, and setal hooks are useful features. Once opened, using similar techniques to the Sipunculid dissection, the nephridia, anal vessicles, body wall musculature, and nephrostomal lips need to be inspected. Helpful Hints for Sipuncula : The genus Onchnesoma is often found 'coiled in gastropod shells, such as Kurtziella and Nassarius . Golfingia minuta is commonly found in Foraminifera shells. Golfingia misakiana are extremely small and are best seen with a compound microscope. The tubules on the contractile vessel are best seen at the junction with the intestine. If your specimen belongs to the genus Themiste , use the species key in Stephen and Edmunds, 1972. For the Echiura: Listriolobus hexamyotus is usually found at depths greater than 300 meters. Juvenile L. pelodes do not display strong muscle bonds and must be carefully examined for additional characters. Males of the Bonnellidae live as parasites within the genital ducts of females. Baby SCAMITES : The newest SCAMITEER was born to John and Debby Dorsey on December 8th. Her name is Kristen Barbara and weighed 3007 g, measured 52 cm in length, and, luckily, had no setae (but lots of nice brown hairi). Correction : Voucher sheets from Vol. 4, No. 8 contained an error; the drawings for Anobothrus gracilis and A. trilobatus were switched. Please note that the Flabelligerid voucher sheets were produced by L. Harris, Marine Biological Consultants.

A Provisional species by B. Thompson, SCCWRP. -2- Vol. 4, No. 9 Travels with Olga Gustafsson Pensionat Sveavagen 108, 4th, (re) Stockholm, Sweden 2 September, 1939 Dear Frieda and Chauncey: You are perhaps better informed of the European situation than I at present, so I shall say nothing of that save that Sweden maintains neutrality. Mobilisation is in effect (you have perhaps read it) but it is only a preventive measure. I left a greatly perturbed London on Monday afternoon (already that seems ages ago), and joined a very heavy stream of traffic going east. All trains and boats were heavily taxed. Most of the passengers were homeward bound, to Denmark, Germany and Sweden. Several were Americans, going to the continent. London was "bedding itself in" with sand bags, and hastily and feverishly preparing against adversity. Many trasures were packed and carried away to comparative safety. War risk insurance bounded upward, and the pound sterling took a flop. The journey across was very beautiful, - via train from Liverpool Street Station (London) to Harwich (east coast of England); on the M/S England (a Danish steamer) across the North Sea to Esbjerg, Denmark; (The North Sea was smooth as glass much of the way); then by Danish special train across Jutland, Ostende, to Copenhagen. I remained the night there in a very nice hotel, and had a typical Danish breakfast. (How vastly different from England!) In Copenhagen I saw more bicycles than I have ever seen before in all my life. They flow along the streets like water, - a constant stream. — And then from Copenhagen to Malmo, Sweden by ferry across the Kattegat, and to Stockholm by Swedish train. The trip was a strain on monetary exchange. I dare say I lost a lot during the process of changing, but there was no choice. I started with shillings and pennies, then to Danish crowns and ores (with holes in the center) and now to Swedish crowns and ores without holes. Coins used here are numerous, but the decimal system is used, hence one can rapidly transpose to foreign exchange. Have just had a "lesson Swedish" with the maid. What a time we do have! She knows only Swedish, I know practically none. I tried to explain to her that this morning I entered a telephone krosk out on the street to call someone in town who speaks English. I deposited 20 ore, dialed the number and crossed my fingers. Across the wire came a long flow of Swedish. When it stopped, I said, "Forstar ni Englesk eller tyska (German)." The answer was nay. So I hung up. I got the story across to the maid but she asked me several questions I did not comprehend. What a time this is going to be! Questions I can formulate, but when I get back a long — -3- Vol. 4, No. 9 volley of Swedish in answer, there is only blank astonishment. Today I went to a stationery store after a pencil sharpener. There was a clerk who spoke German, and then I could not recall the German word for the instrument. Swedish foods are excellent. Milk products are numerous and fine. Butter is served in large masses. Coffee is delicious (England's coffee is terrific but the tea is superb). And there are combinations unheard of in my experience. Clabbered milk is eaten in every form and style, - like soup, with salt or sugar, or bread crumbs, etc. Then there is "appelsoppe," (yes, apple soup , hot, for dessert) meats, in infinite variety, and fishes one does not even dream about. But menus are dreadfully frightening. Professor Bock (Riksmuseum) showed me a good restaurant last night (called Bio Rummet) where the choice is limited and meals well- balanced. It should solve a great problem. The maid brings breakfast to my room, hence that is no bother. The Riksmuseum where I work is in the country. I walk four blocks to a bus station, and for 25 ore go to the museum. It is a short but beautiful ride past lakes and countryside. Accomodations at the museum are wonderful. Instruments are very good, and there are plenty of them. Several of the people there speak either English or German, hence one can communicate. Stockholm has beautiful shops, - especially for glass and silverware. The standard of living is fairly high, - largely because most people receive good wages, and there is no real poverty. The greatest poverty I have seen in England was in Glasgow and along the "Royal Mile" in Edinburgh, - strange as the latter may seem. But there must be a lot of it in London. Have had no word from California for a long time. I wonder how mails are carried. So far as I know, the North Sea is still open for shipping. -4- SCAMIT ORDER FORM T-SHIRTS COLOR 1st 2nd Choice Choice Mens Womens Childrens Blue ( ) ( ) Small ( ) ( ) ( ) Yellow ( ) ( ) Medium ( ) ( ) ( ) Tan ( ) ( ) Large ( ) ( ) ( ) Price: $8.00 plus $.95 postage X-Large XX-Large ( ) ( ) - -Not -Not Available- Available- SCAMIT MUGS One mug $ 6.00 { ) Shipping $ 1.50 Set of 4 22.00 ( ) Shipping 2.00 Set of 6 33.00 ( ) Shipping 2.50 SCAMIT HATS $6.00 each, $.95 postage ( ) VIDEO TAPES These tapes of SCAMIT guest lecturers are available for viewing on VHS recorders.

TRAVELS WITH OLGA (A postcard:) Gustafsson Pensionat Sveavagen 108, 4re Stockholm, Sweden 10 Sept '39 Dear Frieda and Chauncey: Sweden is as beautiful as it is reputed to be, and at present its tranquility is a source of real comfort. No predictions can be made as to general European conditions, but I rather expect that unless things clear up within lh months, that I may seek passage to U.S.A. by November. Regulations of foreigners in any European country have become very strict since the declaration of open billigerency. Greetings and best wishes to you both. (A postcard:) Gustafsson Pensionat Stockholm, Sweden 12 Sept '39 Dear Albert: X marks the spot, (on P.C., a picture of the city library and children's wading pool, on one side, a row of apartments), of my two windows that look out on a beautiful park. Your letters have been arriving, for which I thank you warmly. There is no American Express in Stockholm, so use either the Naturhistoriska Riksmuseum, or the above house address. The 4re refers to floor number. There is so much to learn here, and to see, and time is all too brief. My plans may need revamping before long. The European situation is not too promising, but no one knows. SCAMIT SYSTEMATIC CATALOGUE OF SOUTHERN CALIFORNIA INVERTEBRATES A Request For Comments SCAMIT is .considering the production o-f a systematic catalogue of marine invertebrates from Southern California. It is intended that such a catalogue be of use primarily to biologists carrying out, or interested in, faunal surveys of the region. It is also intended that the catalogue be maintained as a ”living" document after its initial publication so that subsequent editions can be published at appropriate intervals. Beyond these statments there are many decisions that must be made regarding the catalogue. Members are requested to provide comments on the following issues and make any suggestions that are not considered here. The resulting comments will aid in the development of the scope and format of the catalogue. Once that is accomplished, a plan of action can be drawn up for compilation and production. Remember when considering these issues and what you would like to see in the catalogue that the real work of compiling the information will fall on the shoulders of individual SCAMIT members, perhaps including yourself; it is important that the catalogue be both useful in its scope and content, and be within our organization’s ability to produce. 1. What should be the geographic and bathymetric limits of coverage? Straughan & Klink 1980 covered Pt. Conception to the Mexican Border and excluded "deep water species"; the actual limits were determined by the individual contributors. It would be perhaps more useful to strictly delimit the scope so that all groups are treated equally in this regard. 2. Should the catalogue be limited to benthic and epibenthic species, or should planktonic species be included? Should intertidal organisms be included? 3. What shall constitute a valid record of the occurence of a species? Shall published records be the only acceptable source? Do the un¬ published reports from various monitoring studies constitute valid records? 4. What groups, if any should be excluded from consideration? Should groups comprised of usually small animals, such as the Nematoda or Oligochaeta be excluded. What about obscure taxa (e.g. Kinorhyncha) 5. It has been suggested that the entire systematic composition of a phyla on a worldwide basis be listed down to a suprageneric level (perhaps the familial level) with those groups (families?) without local representitives being noted as extra-limital, freshwater, terrestial, etc. 6. How extensive should the synonoray be? Should the list be confined to the most common synonyms or should an attempt be made to be exhautive? 7. How should provisional species be treated? It would seem valuable for the user of this catalogue to be aware that a considerable portion of the S. Calif fauna is undescribed. It has been suggested that for each group in the catalogue an addendum be provided that lists by genus (or appropriate taxon) the number of provisional species recognized in the region. 8. Should the listing be annotated? If so, what kind of information should be considered for inclusion in the annotations? 9. Should an index be provided? If so, should taxa, genera only, genera and above, etc.? it be an index to all 10. Should a bibliography be included? be? How should it be limited? If so, how extensive should it 11. What format should be used for the systematic listing? It has been suggested that an indented format with all suprageneric taxa explictly indentified (similar to Keen & Coan 1974) be adopted. 12. Are you willing to participate in the compilation of the catalogue? Please forward your response to: Dave Montagne Marine Biology Laboratory County Sanitation Districts of Los Angeles County 24501 S.

Long Beach, CA 9080£ This small phylum of marine pro tos tomes is well represented in southern California waters. The only previous reports of the echiurans of this area are those of Fisher (1946, 1948, 1949); he recorded 7 species. Recent large scale surveys of the benthos of the entire southern California borderland have collected many addi¬ tional taxa. The following is a complete listing of all echiurans previously reported in the literature or seen in collections examined from southern California. * It in¬ cludes species from benthic habitats ranging from inter¬ tidal to bathyal depths. Collections examined include those from the Allan Hancock Foundation, Scripps Institution of Oceanography, and the Santa Barbara Museum of Natural History. The list is probably still incomplete. Several single * specimens of interest" have been examined and may represent 1 to 3 additional genera. The classification used is the one proposed by Fisher (1946) and adopted by Stephen and Edmonds (1972).

Long Beach, CA 90806 The sipunculan fauna of southern California is poorly known. The first report was that of Chamberlain (1918). Fisher’s (1950a,b, 1952) work provides the only major reference for this group. He erected subgenera for the genus Golfingia and described nearly all of the intertidal sipunculans, but only a few of the species from offshore. Recently however, several large scale surveys of the intertidal and benthic habitats of the entire southern California borderland have collected many species not reported from this area, including several apparently new taxa. This listing includes all previously reported sipunculans and also includes species seen in collections from southern California. It includes species from inter¬ tidal to bathyal habitats. The classification used is based upon the families of Stephen and Edmonds (1972), and the subgenera of Fisher (1952), as revised by Stephen and Edmonds (1972), Cutler and Murina (1977), and Cutler (1979).

Many of these names, as originally erected, were given broad distributional ranges. These ranges and the species descriptions have since been refined and resulted in numerous new species names and combinations with more restricted distributional ranges. Many of the older species (e.g. Peloscolex gabriellae , Marcus 1950) had many polypheletic characters and have since been eliminated or modified by successive revisions.

You may be interested to know that your last letter has been opened and resealed. There is extreme caution now in everything sent in or out. Furthermore, apparently few boats are able to come through, and air service is indefinitely stopped. Thus, I take it that if there is any word enroute, it will be slow to arrive here. I am having trouble getting my luggage in from London. It is, apparently, still at the London docks, with no boats available. All schedules have been cancelled, and no one knows when service will be resumed. I have cabled several times to London, inquiring, but there is little hope. Yesterday, I called on Mr. Sterling, the American minister to Stockholm, asking the possibility of my going over to get my baggage. He said he could arrange a visa for me to get to London, and another that I could re-enter Sweden, but that he had no idea how one could get over and back. There are tramp cargoes shuttling back and forth, but entirely unannounced. This is indeed a strange situation. Cables and telegrams still function, but one is permitted no code whatsoever, not even in addresses. Sweden maintains its neutrality, but no one predicts how long. In the meantime, preparations are made against the possiblity of air raids. Bensin (in U.S., gasoline) and England, (petrol) is prohibitive, and only certain classes of transportation are allowed its use.. One sees trucks, taxi cabs, busses, and "tjanstbil" (service cars), but no private cars, although privately owned cars are very common. It is a great pity that they cannot use alcohol, since there might be an unlimited supply of that here. Winter is graudally coming on. There has been no frost yet, but it cannot have been far above that. The flowers are still very beautiful, as all vegetation, but frosts will change that. The city, however, is ramified with beautiful waterways, and pleasant hills and valleys. I imagine Stockholm is beautiful in any season. The language is still a handicap for me, but one gradually learns it. It is far easier to read than to hear it spoken. There are three letters, a, a and 6, not represented in English, but w does not exist. The a (pronounced 5) is very common in words, and the "sk" is about as difficult for me as the "th" for a Scandinavian. English is taught in the schools, hence many of the younger people know some English (book), also German (tysk). American movies are very popular and perhaps teach a good deal of English. But the language of the streets and homes is Swedish. Here is assign, posted in all street cars (called, appropriately. "Sparvagar"): "Du, som ar ung och frisk, lamne Din sittplats at den some battre behover den" (meaning youth relinquish seat to age). Courtesy and good behavior are both obviously important. Food and service are excellent. Butter is better and more plentiful than any place I have ever seen. It is always served in quantity and in some ornamental shape. Breads are variable, often somewhat sweet, some with anise, or other condiment. And sweets and pastries are made in endless varieties. Meats are never monotonous (or even fish). One has lamb with dill sauce, or "kolsoppa med kow" (cabbage soup with sausages); bif med lignon (roast with whortleberry) etc., etc. The Smorgasbricka in one place at least, is served in a fascinating manner. There is a service plate, ca. 15 inches long, rectangular, with 5 depressions, each of which has a different delicacy; thus, spiced herring, baked ham with boiled egg and vegetable, cheese, vegetable salad, boiled potatoes. This comes in many varieties BUT ALWAYS good. I shall say nothing of the continental situation. You know much more of that than I, since only Swedish newspapers are now available to me. Professor Bock told me that the Grippsholm (Swedish passenger boat) left yesterday for America, with a full passenger list. I gather also that there may be as many as 4 boats a month, leaving Scandinavia, (The Grippsholm left Gothenburg), but some of the Norwegian boats leave from Bergen or Stavanger). I take it, therefore, that one can obtain passage to America, if imperative. You will realize, of course, that ocean service has been greatly reduced, hence I hope you will not be too concerned if letters can not go through often. I have asked the American Assoc. Uni Women for permission to finish my year in the east after completing work in Stockholm, but have not yet heard. Thus I may leave from Scandi¬ navia before the year is out. You would much enjoy this beautiful country. I hope you will see it some day.

Cadien, MBC Applied Environmental Sciences 10 February 1986 According to Barnard & Given cumaceans are the third most common type of microcrustacean taken in benthic core samples, surpassed in number only by amphipods and ostracods. Despite their abundance they are relatively poorly described. Of the 120+ species known to occur in California nearshore waters less than 1/3 have been described in the open literature, although a far larger percentage are in common usage within the local taxonomic community. Even so, cumaceans remain one of the least effectively standardized of the microcrustacean groups. Although some descriptive work on the Californian cumaceans was done in the early part of this century by Zimmer and Caiman, and some of the species described by Hart and Lie from Puget Sound and Vancouver Island prove to range commonly into our area, the California regional biota was not "worked up" prior to the investigations of Given. In the process of working on the collections amassed during the AHF State Survey of the mainland shelf Given described several species and erected a series of provisional names for others which he did not formally publish. These became available through his contacts within the community and through tiie circulation of his 1970 Thesis. In the thesis several of the provisionals were illustrated, and brief diagnoses were presented for a number of the others. Quite a few remained unknown quantitites, however, because of ambiguities in their diagnoses, or inadequacies of Given's original material. Even some of the described species (ie. Leucon armatus ) were little knowrn beyond their original diagnosis. The situation was relatively stable for some years after Given's thesis became available. Almost all of the monitoring work undertaken in California was from waters over the inshore portion of the shelf, and few species which had not been presented by Given were found. Then several major explorations of habitats not. normally within the range of monitoring programs were performed. First the BLM sampling of the southern California borderland, and more recently the MMS reconnaissance of the southern Santa Maria Basin and Santa Lucia Bank. The new species added to the list of California cumaceans in these two efforts have left us in the unenviable position of having a largely undescribed fauna. Despite the lack of officially described species there are now mechanisms (SCAMIT chief among them) which allow intercalibration between those actively working with the undescribed species. It is with the hope that inter calibration and standardized use of provisional names will result that I am presenting a "rogues gallery" of new cumaceans encountered in our samplings between the Mexican border and Point Estero at depths between 6 and 1000 meters.

Palae absent. 2. Four pairs branchiae, long and subulate. The anterior two pairs inserted on the same segment with the remaining two pairs following on successive segments, forming an oblique, medially directed line. 3. Prostomium trilobed, with a pair of transverse nuchal organs. 4. Rudimentary notopodia present on segments 4 and 5; a few very fine setae barely emerge from segment 5. Notopodia of following 12 segments normal. 5. Thoracic uncingers number 11. 6. Abdomen with 10-11 abdominal segments; notopodial rudiments and dorsal cirri present. Pygidium with two conical papillae. REMARKS: This species will be moved to Paramage due to the rudimentary notopodia. In Amage , the anterior segments are fused and these structures are absent (Williams, in press). Amage longibranchiata has similar rudimentary notopodia, but has branchiae on separate successive segments and therefore belongs to Mexamage (Williams, in press).

Thoracic setigers 17, including 16 uncingers; uncini (Fig. 1) in double rows from setiger 7/8. 2. In the posterior thorax, the tori gradually extend across the ventrum until they almost meet in the last two thoracic segments (Fig. 2). 3. Branchiae three pairs, the first pair largest. Terminal branches very short and originate in series rather than dichotomously, forming a whorl or spiral (Fig. 3). 4. Tentacular lobe with narrow band of eyespots. 5. Latero-ventral folds conspicuous, largest on first branchial segment. RELATED SPECIES AND DIFFERENCES: Eupolymnia congruens : gills clearly dichotomously branched (see Hartman, 1969 p. 589). REMARKS: 1. Banse (1980) synonomized E. crescentis and E. heterobranchia and provided a detailed redescription. 2. Due to the presence of lateral folds, this species could be keyed to E. congruens in Hartman, 1969. The species key is a bit misleading for the genus; thorough reading of the diagnoses is recommended. DISTRIBUTION: Alaska to western Mexico; intertidal and shelf depths.
