. Bulletin. Science; Natural history; Natural history. 92 SOUTHERN CALIFORNIA ACADEMY OF SCIENCES. Fig. 2. Photograph of "school" of medusae, taken from video monitor, showing density of the jellyfish ofTCoronado Norte, Islas de Los Coronados, Baja California, Mexico, July, 1989. At least 7 animals are in the field of view, 3 on either side of central largest (closest) animal. in association with this new species. Additionally, we discuss this unusual oc- currence in light of other unusual species occurrences in the area. Materials and Methods The first scyphomedusa specimen seen by us was collected on 20 August 1989 by B. T. Hogue and D. Golles, both lifeguards at Venice Beach with over 43 years combined experience (8 Hogue, 35 Golles) in the area without having seen this species. This large (approximately 23 cm bell diameter) living medusa was col- lected approximately 100 m offshore of Venice Beach, California. The medusa was donated to the Natural History Museum of Los Angeles County (LACM) and was brought to our attention because of the number of juvenile brachyuran crabs found on the manubrium (oral arms) and subumbrellar surface of the bell; it was subsequently catalogued as LACM 89-206.1 An additional live specimen (LACM 89-205.1, bell diameter approximately 25 cm) was collected on 25 August 1989 by the LACM Ichthyology Section just north of the Marina del Ray jetty, Venice, California. The authors counted another 24 dead specimens washed ashore along Venice Beach on 25 August 1989 and collected one dead specimen (LACM 89- 26.1, bell diameter approximately 24 cm) floating on the surface in the surf zone. Another dead specimen (bell diameter approximately 22 cm) was collected by staff members of the Cabrillo Marine Museum near Long Beach, California (Table.
