 note = {Hclocynthia roretzi (Drasche) is a mid- and infra-littoral edible ascidian, occurring in the Japan Sea and vicinity. It has not yet been recorded by modern ascidian taxonomists from the shores of Mie and Aichi Prefectures on the Pacific coast of central Japan, while it is known to occur nearby in Osaka and Sagami Bays. Results of a questionnaire addressed in 1996 to an the marine fishermen's associations of these two prefectures and some additional inquiries revealed that some shores have been inhabited by the ascidian since 1990 or earlier (i. e., as long as 20 or 30 years). The ascidian was obviously referable to H. roretzi "Type C" sensu Numakunai & Hoshino (1973, 1974). Surveys of historical documents and old literature showed that the ascidian may have occurred in this area early in the 10th century (in Mikawa Bay), in the middle of the Edo Period (in Ago May of the Kii Peninsula), and around 1897 (off Toba in Ise Bay). The possibility that H. roretzi is an index species of marine environmental changes in central Japan is briefly discussed.},
