Subsequent to this report, specimens of this species were collected from California waters, but data on these collections were not published (Cressey pers. comm.). The report of Pandaris hicolor and Perissopus ohlongatiis on the sharks mentioned represents a new host-parasite record. Both of these pandarid copepods are normally found attached to the fins and dorsal surface of the fish's body. They occur most often above the gill openings, around the head, and on the trailing edges of fins. They occasionally occur in small numbers away from the edges of the pectoral and pelvic fins. The frayed edges of the dorsal fins often sup- port large numbers of either or both of these parasites. On October 19, 1972, we found 31 Perissopus ohlongatus attached on opposite sides of the first dorsal fin of a 109-em (43-inch) female leopard shark. A third pandarid copepod, Echthrogalcus coleoptratus, has been re- ported from a large variety of pelagic sharks including blue sharks, Prionacc glauca. It occurs on the body and fins of leopard sharks but is less noticeable than either of the other two pandarid copepods. Echthrogalcus coleoptratus is approximately 1 cm ( inch) total length. A fourth copepod, Lerncopoda scylicola (Lerneopididae) (Figure 3), was found during our investigations on a single leopard shark and a single skate, Baja hinoculata. It was previously known to occur only on sharks of the genus Scyllium (Cressey pers. comm.), which has since been divided into several new genera. This parasite is apparently rare, since we have encouilterod
