I will try to find sométhing better. Addressing and licking envelopes is a real pain. The March issue of volume thirteen was mislabeled as issue 2. I apologize for the error. .The page numbers are correct. One.of the beauties of a computer is that it allows you to make mistakes much more efficiently. I have been keeping most of my opisthobranch papers and microfiche in storage for the past five years. This makes iU very difficult to find some papers when copies are requested. I hope to have my office set up within the next two months or so. Please bear. .with me. If I cannot find a requested paper I will try to list it in the ON so that someone else can help the requestor. FOR SALE Airmail postage and handling for Dave Behrens opisthobranch book is $6.00.

PURPOSE OF THE OPISTHOBRANCH NEWSLETTER The primary purpose of the Opisthobranch Newsletter is to assist people working with Opisthobranch mollusks. The newsletter has been published since 1969 and was inititated to facilitate research and information | exchange by researchers and interested amateurs in all parts of the world. Personal notes on researches, trips, etc.; notices of meetings; recent publications concerning Opisthobranchs; and short articles on Opisthobranchs are included in issues. In addition, I try to include bibliographical citations on every paper noting Opisthobranchs. INSTRUCTIONS TO AUTHORS I am very dependent on input from subscribers to maintain the information content of the Opisthobranch Newsletter. Notes and articles should be addressed to Steven J. Long at the address given above. Please include scientific meeting dates and other information even if they may be of ony (po gia If material is specifically not for publication please note a act. Articles for publication should be typewritten and laid out exactly as you | would like them published including any drawings at the final size and placed | where you would like them in the text. It is suggested that you use a "cut and paste" Xerox copy of the materials to lay out your format and include _the originals to any drawings and typescript separately. | I currently have very limited resources for photo reduction so the illustrations should be sent to fit on my normal page format. The text will all be put into my computer text editing system manually and then printed out automatically. Publications will be reviewed by one or more of your peers for style and content. If time permits you will receive a galley proof for your review prior to publication. Please refer to the biological style manuals for basic guidance and to the past issues of the Opisthobranch Newsletter for examples of acceptable citation and drawing formats. Note that I have decided to use complete bibliographical citations with papers published in the Opisthobranch Newsletter. READER FORUM From David Behrens (416 Lilac Drive, Los Osos, CA 93402): "Hurst (1967) reports Catriona aurantia from Puget Sound. Has C. aurantia (now C. gymnota been collected since, or is it possible that Hurst s critter was Catriona _ cOlumbiana (=C. alpha)? Miller (1977) reports Catriona alpha from New | Zealand. Although Williams & Gosliner (1980) refute this species as not being conspecific with C. alpha by Baba & Hamatani, 1963, I am curious to | know whether there are other possible examples of species occurring circun- Pacificly. To my knowledge Diaulula sandiegensis and Aldisa sanguinea may have the widest range, of those species recognized, to occur on both shores. OPISTHOBRANCH NEWSLETTER Volume 13, Number 5, Page i18 I am unaware, however, of any species occurring in both the north and south Pacific. How about co~occurrences between Hawaii and California? None [I hope." EDITOR’S NOTE Thanks to all of you who have sent commemorative and other colorful stamps over the years. They are still much appreciated:-Thanks. to..Dr. I.S. Roginskaya, Dr. Eveline Marcus, Annetrudi Kress, N.'B. Eales, Jim Lance, Dave Behrens, Kerry B. Clark, Don Cadien, and others who have recently contributed material for the ON. Keep it coming! I realize that the current citation format is not quite as readable as the older one but my word processing system makes: it very useful to indent in the fashinon now used. Perhaps I will be able to change later. I will attempt to set up for two column printing soon if I am able to overcome a basic machine problem. « I work hard trying. to keep typographical and other errors out of the ON. If you note any please contact me immediately. I would far rather have 25 people remind me than let an error go by indefinitely. I am especially interested in duplicate citation numbers. I will try to include a complete list of deleted citation numbers in a future issue of the ON. PERSONAL NOTES Eveline Marcus will be spending September in the USA again this year including visits with Trish Morse, Harald Reader, and Robert Work." Dro you have the opportunity to be in Washington D.C., Massachusetts, or Florida one ae month contact, Eveline soon .and,.see. if, your schedules can coincide. Eveline writes: "I am fighting with the Pleurobranchaea of the Western Atlantic; the older bibliography, also our own,-is often unsatisfactory: .and preparation of the absolutely necessary male organ takes time. Already old Vayssiere noted that in his good paper 1901. From Jeff Hamann: "Had .a fantastic. trip, to. Saudi,Arabia.with my, Dad in March. Found 39 species of Opisthobranchs single-handedly in two weeks. Conditions were perfect & I brought home some great pictures. I went to L.A. Bay [Mexico] with Hans [Bertsch] and Jim [Lance] last weekend & had a treacherous time. We flew in and blew a tire on landing but kept it on the strip somehow. Then the front shock went out later & we bent $1,800.00 worth of propeller in the dirt. We scrounged up enough tools to | repair the tire & bent the prop back with rocks & made it home. We collected one morning and the three of us got 28 species." William Jaeckel is presently compiling a short note on distribution extensions from Humboldt: County, California. If anyone has additional records for inclusion please contact him. From Ian Loch: "Bill Rudman has been working through a series of Panes on aeolids associated with soft corals, the scleractinian Porites, the zoanthid Palythoa and a few odds and ends. One is an odd little tergipedid with branched cerata which mimic the polyps of a hydroid living on sponge. A few odd aeolid-like arminids got involved on Porites and Heliopora. The soft coral associates involved work on the utilization of zooxanthellae by the aeolids and adaptations for this. EoueuD ae at Sydney University, Ros Hinde has been looking at chloroplast utilization by local sacoglossans, so expertise is on.tap.- One of her. students is finishing ‘a Ph. D. project.on some local Elysia with some interesting observations on changing food sources. Another has recently commenced aM. Sc. on zooxanthellae utilization by Pteraeolidia ianthina. Bill has gone back to working mainly on chromodorids, as he has a grant for a research assistant for this. Geoff Avern, the research assistant, is also starting.aM. Se. project on life, histories of a couple of local chromodorids. Other local post graduate work has. Bob Rose writing up,a Ph. D. project ion reproductive strategies and developmental types of some local dorids, and another is sereening for a suitable beast to do a Ph. D. project on biochemical inducers of larval settlement. Most of these projects unearth nasty taxonomic problems, even the Pteraeolidia ianthina comes in an albino rorm'. Somewhat belated news is that The Australian Museum produced a 1981 calendar featuring opisthobranchs. The 20-25cm photos on. black background are Hydatina physis, Stiliger, Elysia, Berghia, Phyllodesmium poindimiei, Phyllodesmium, Chromodoris, Hypselodoris obscura, Halgerda aurantiomacul Novodoris gardineri, Phyllidia ocellata and Ceratosoma brevicaudatum. I gather some are still available if anyone is interested. Sherman Bleakney visited for several days, recouperating from an illness and looking at a few local Sacoglossans. Local collecting continues to produce a stream of OPISTHOBRANCH NEWSLETTER Volume 13, Number 5, Page 19 interesting (and undescribed) opisthobranchs. Bill seldom has to leave his microscope with the volume of animals the activities of the students, interested amateurs and other museum staff generate. The Malacology Dept. staff did spend several days in October at Port Stephens, about 100 miles morth o\f. Sydney, where about 50:species-were collected, including a live Leucotina."
