a broad dorsal ridge is the last The coloration of the new coat is on an average a dark slatey-grey region to change in the dark parts and a yellowish white in the light, but the exact shades vary very much in their intensity / only one bad case was seen and that was on a this year's seal, which had a large bare patch over the back of the skull (an unusual situation), extending the whole width of the skull about inches in width at and it had one eye badly injured A large proportion, both male and its greatest Not many of these seals showed scars female, have sores Jan 30th (now mostly healed) about the genital organs A male sea-leopard shot on the North Beach Length, feet 1H stomach contained only a great quantity of small crustaceans 31st Three species of penguins;
