January 19S3 vol. 1. Wo. 10 Next Scheduled Meeting: February 14, 1983 Place: Marine Biological Consultants 947 Newhsl1 Street Costa Mesa, CA 92627 Specimen Exchange Group: Topic Taxcnonilc Group: Cephalaspidean Molluscs Eunicidae and Lurabrineridoe MINUTES FROM JANUARY 17, 1933 The rrefct’ng was quite Interesting and st imaiating. Two presenta t'ons were given, one on data handling and the other cn a microscopic '-ideo display system. Steven Long discussed at length on his methods for data storage and retrie'^al. Through experience with his cpi s thobranch work he found microfilm is advantageous because it is inexpensive and uses very little storage space. IL is also very easy and inexpensive to make additional copies From microfilm Files. Older literature can be micrcfHnied rather than photocopied to produce better copy and will include photographs that normally cannot be reproduced. John Parsons demonstrated a Nikon v'deo system that can be mounted on a stereo or compound microscope. The system produced very clear images anh will be a tremendous aid during meetings for viev/ing characteristic features of organisms, A system like this is first on che list of major purchases by SCAM IT and is greatly neededi Reprint Sale : The Hancock Library of Eiciegy and Oceanography at USC began a new procedure for sa’e material. Literature repr'D^s and such will be placed in a ’’for sale*’ sect ion of the Reading Room. Nev; material will be* added cn a reguiar oasis and articles unsold after C. W. CARRY . WALTER L. NEWSLETTER VoK 1, No. 10 JANUARY 1983 two weeks will be removed. The sale includes reprints from the U.S. National Museum. This policy should make trips to USC profitable for people who collect literature. Chloeia^ What? 3 ^^ Williams mailed some specimens of Ch j oela to Kristian Fauchald and the results were that two species do occur off this coast. One is inshore and one is offshore. Have patience; notes and voucher specimens are coming to help clear up this particular systematic stymie. Species Requests : Do you have pycnogonids that need to be identified? Bonnie Bain would love to look at them for you. She is looking for any and ail species of pycnogonids that you can spare. Send them to her at: 603 ^ Malcolm Drive, San Diego, CA 92115. Leslie Harris has been trying to determine the identity of a species of Ninoe . She would like more material. Please send any specimens to her at: SCCWRP, 646 W. Pacific Coast Highway, Long Beach, CA 9 O 8 O 6 . Research at Catalina : Jack Engle and Bob Given sent word across the channel that they would like to encourage people to do research work at Catalina -Island. They can offer free transportation for Interested people. For nwre information write to them at: Catalina Marine Science Center, P. 0. Box 398, Avalon, CA 90704. Helpful Hints : Ever tried to rehydrate a specimen that has dried out? An article published a few years tzzk in Crustaceana has a method that na? been quite successful according to the folks from Hyperion. Just soak the dried specimen in a 50^ aqueous solution of ethylene glycol then transfer, first to 50^ alcohol, then to 70^ alcohol. Or begin with a 50 ^ alcohol-ethylene glycol solution.
