Text Appearing Before Image: 200 ENRIQUE BALECH to the genus Peridinium was clearly correct, but they bore only superficial re- semblances to Scrippsiella sweeneyi. The genus is named after the institution at which it was discovered, and the species is dedicated to Dr. Beatrice M. Sweeney who made the original isolation and whose cultures made this study possible. Fragilidium heterolobum n. gen. n. sp. G Text Appearing After Image: FIGURE 3. Fragilidium heterolobum. a) A typical individual, ventral view, b) Apical view of the epitheca. c) Sulcal plates, d) Antapical view of the hypotheca. All figures about X 1000. Diagnosis. Medium-sized, roughly roundish pentagonal in ventral view. Epitheca dome-shaped; hypotheca asymmetrically bipedal, the left lobe being the largest. Cingulum deeply impressed, subcentral, descending, displaced distally about one girdle width, without lists. The cingulum has eleven sub-equal rec- tangular plates plus a transitional plate at the right end. Sulcus narrow, only slightly excavated, with six plates. Theca easily exuviated.

context_page_description: Eleanor Beatrice Marcy "Beazy" Sweeney was an American plant physiologist and a pioneering investigator into circadian rhythms. She was professor emerita at University of California, Santa Barbara.
  Having started her career as a botanist, serendipity led her to dinoflagellate research. She investigated circadian rhythms in photoluminescent dinoflagellates, and other single celled organisms. Later in her career she served as a senior officer in many scientific organizations, including the American Association for the Advancement of Science and the American Institute of Biological Sciences.
context_section_description: Following the completion of her Ph.D., she followed her first husband to Rochester, MD. She was initially unable to find an academic job in botany, so she worked as a lab technician. She then worked as a postdoctoral fellow at the Mayo Clinic. She again followed her husband to San Diego, and she found employment at the Scripps Institution of Oceanography, where she first began working with dinoflagellates, and began her investigations in circadian rhythms. In 1961 she moved to Yale, where she was appointed a lecturer in algal physiology. However, at Yale she was never given a permanent position, so in 1967, she returned to the west coast, with an appointment at the University of California, Santa Barbara, where she was made professor in 1971, and professor emerita in 1982. She served as the associate provost of College of Creative Studies from 1978 to 1981.
  While in Santa Barbara, Sweeney gave a tour of the campus to the daughter of a family friend, future Nobel laureate Carol W. Greider, who was a high school student at the time. This led to Greider studying at the College of Creative Studies. Sweeney introduced Greider to research during her freshman year, and mentored her throughout the rest of her time at UCSB.
  Sweeney was president of the American Society for Photobiology in 1979, the American Institute of Biological Sciences in 1980, the pacific division of the American Association for the Advancement of Science in 1981, and the Phycological Society of America in 1986.
  In 1983, the Botanical Society of America awarded her the Darbaker Prize for Study of Microscopic Algae, with the citation as follows:
  Dr. Sweeney is a world-respected innovator in the study of circadian rhythms, particularly in the dinoflagellates. By bringing dinoflagellates into culture and by defining their multiple photoperiodic responses, especially the physiological and ultrastructural aspects of the circadian rhythms of their bioluminescence, she has influenced the research direction of many laboratories.
  She received honorary doctorates from Umeå University in 1985, and Knox College in 1986.
  She suffered a stroke on 30 June 1989 while traveling to the Gordon Conference on Chronobiology, while visiting the Marine Biological Laboratory at the invitation of her long time collaborator John Woodland Hastings, and fell into a coma. She died on 17 July 1989.
