The geographical ranges of fourteen species of Opisthobranch molluscs are extended beyond those reported by Behrens (1980) and McDonald & Nybakken (1981).

This volcanic group, about 1500 km south of San Diego and 600 km west of mainland Mexico, consists of four principal islands with one, San Benedicto, having blown its OPISTHOBRANCH NEWSLETTER Volume 13, Number 6, Page 22 top about 30 years ago and remaining almost totally barren to this day. Our ship, the Alpha Helix, was until recently the flag vessel of the Scripps research fleet and was well equipped for investigations at sea. Althought our program was primarily oriented toward the collecting of algae and invertebrates for natural products chemistry research, my 14 eae A ant a aboard were yeuy cooperative in extending their activities to helpina | survey of the opisthobranch population from these and the more inshore Tres Marias Islands. | Although we circled the islands from seaward, it was evident from observation, charts and | enormous surf that intertidal or inshore collecting wouldn't prove feasible. Thus, most of our . work was confined to offshore snorkel and SCUBA. In all, I was able to record only a rather | disappointing 21 species conse of 123 specimens. Still, 5 of those are undescribed and one, an elysoid sacoglossan, probably represents a new genus with affinites to both Caribbean | and Indo-Pacific relatives." - Jim Lance. | From Bob Burn: "The first two weeks of April, I spent with Fred Wells of the Western Australian Museum. Six days were taken up with field work in the Atbany area of southern | Western Australia, where we collected on soft bottoms, among seagrasses and on reef platforms | with amen te results. Albany is situated on King George Sound, an area visited and collected | by Quoy and Gaimard in October 1826. These Frenchmen described several bubble shells from | that locality -- namely Liloa brevis, Akera bicincta, Adamnestia arachis and Bulla australis (now B. quoyii Gray). We were fortunate enough to find all except the third species. Tornatina apicluata Take also has its type locality in King George Sound, and a number of living specimens were found. | Two range extensions are worth mentioning. Aplysia gigantea Sowerby 1869 was found 400 km further south and east than normal, and Crimora multidigitalis Burn 1957 was found 2500 km further west than previously reported." - Bob Burn. | From Kikutar6é Baba: "In March I visited New Zealand and Sydney for a short time. | Fortunately I was able to speak with Dr. M.C. Miller of the Auckland University at his residence, | and Dr. R.W. Rudman of the Australian Museum at his office. ! In May I tried again to study Melibe of Japan rather extensively. Possibly the most common form of our Melibe is referable to Melibe pilosa Pease, 1860 in its wide sense, as some of the previous authors suggested. The types of M. papillosa (de Filippi, 1867) and M. vexillifera Bergh, 1880 seemed to be based both on juvenile specimens of M. pilosa Pease, 1860 (s.1.). It is hoped, however ; that the pilosa specimens from Hawaii will be studied in more detail by the local workers." - Kikutaro Baba CURRENT EVENTS: The Los Angeles Oceanic Society’s Coastal Monitoring Conference, Seasons in the Sea, will held Saturday, June 13, 1981, at the Chace Park Community Building Mindanao Way, Marina Del Rey, California. Several papers on marine life and marine features will be given. One paper by John Scotesi is entitled: Sea Hare Migration Phenomenon off Palos Verdes. Conference pre- registration is $3.00 per person. { The fourteenth annual meeting of the Western Society of Malacologists will be held from June 23, 1981, to June 26, 1981, at San Diego State University. Olmeca Hall will be the focal point for housing and some of' the evening small gatherings. The actual meetings will be in Aztec Center Council Chamber.

I have been working for several months to complete an index for publication in the ON and have decided that it should be printed in draft form so that people can start using it and, hopefully, send additions and corrections. The wait should be wortnwhile. Thanks to Dave Behrens, J. A. Ortea, Itaru Usuki, Terry Gosliner, Malcolm Edmunds, William Jaeckle, R.

PAPER Range Extensions of Several Opisthobranchs from Humboldt County, California by William Jaeckle Recent publications (Behrens, 1980; McDonald and Nybakken, 1961) have contributed signifi- cantly to our Knowledge of the biology of opisthobrancn molluscs from the Nortneast Pacific. However, because of the paucity of puolisned accounts from northern California and Oregon, the zoogeographical information within tnese works is, in severai cases, inaccurate. Historically, studies of opisthobranch molluscs have centered around two geographical regions: from Bodega Bay, California ja-C ia, Mexico, and from northwe 1 northwest Britisn Columtia, Can distributions of the specie t } littoral zone reflect the intensity of study in 12) Oo QO 0g 13) 02 'T) ry ny al f ct 5} fm = . > F Dae . ia Spiess ite : fase ae es 2 Seep beay oe ot ye i Real + ~ : Sead es ss sass:
