Dorso-lateral view of a rare leucistic Spiny Dogfish, Squalus acanthias, captured about 2 km off Boars Head, Bay of Fundy, Nova Scotia, Canada at 44°23'N, 66°15'W, by Stewart Taylor, Captain of the longhner Nadia C, of Centreville, Digby County, on 22 May 1989. an elongate blotch mm long on the left caudal peduncle upper margin somewhat behind the caudal fin origin, matched by a similar blotch mm long on the right side but somewhat posterior to the one on the left; and a blotch, about 15 mm wide, con- cealed in each pectoral fin axil. Fr0iland (1975) provides the only other confirmed record of a leucistic Spiny Dogfish, taken in the North Sea in the late 1960s (with a verbal record of an earlier capture). This specimen was a female, 990 mm total length. Captain Taylor and other fishermen in the area of capture of the Nova Scotian specimen confirm that this is the first "pure white" dogfish seen. Normal-coloured dogfish were numerous in the area at the time of capture of the leucistic specimen. Acknowledgments We are indebted to Captain Taylor who captured this Spiny Dogfish, and to Claire Doucette, Fisheries Officer, Dibgy for bringing it to the Nova Scotia Museum.
