Age-frequency distribution of pups tagged at the Basque Islands and Sable Island. Roman figures denote the age groupings described in Table I. in two groups on the east spit, 15 along the north coast and 100 in two groups at the end of the west spit, with another 30 on a sand bar a few hundred yards further on. On January 26, 1962, we again observed much the same distribution, though now the seals were scattered rather than being packed into a few dense groups. Most of the breed- ing seals were confined to the proximal four miles of the eastern spit, since the remainder of the sand bar, except for several hundred yards at the eastern tip, was flooded. We counted 99 adult males, 161 females with possibly some immatures, and 112 white.
