There is nothing in this description which would exclude it from well-recognised zoological classification. It is highly probable that it was one of the seal tribe, but of a species, perhaps a genus, not yet identified. All analogy would suggest that fore-paws must have been present in an animal with a dog-like head, and clothed with hair; but they were perhaps small,--smaller even than in other _Phocadæ_, and may have been so concealed in the long hair, or held so closely pressed to the body, as not to be visible. The only other difficulty is in the posterior extremity. This is described by Steller in terms that imply a true piscine tail, expanded in a direction vertical to the plane of the body, and of that peculiar form called _heterocercal_, which distinguishes the cartilaginous families of Fishes, the Sharks and Rays. But the animal was indubitably a Mammal; and therefore we may almost with certainty assume that, if the body terminated in a natatory expansion, it would be, as in the whales, and manatees, a horizontal expansion, and not a vertical one. But if the strange creature was indeed, as I conclude, of the Phocine type, we have only to suppose the tail, which is usually very small in this family, to have been so greatly developed, as to exceed the united hind feet, which may have been small, and the appearance, seen momentarily, and in the wash of the waves, might well seem that of a heterocercal tail. Captain Weddell, well known for his geographical discoveries in the extreme south of the globe, relates the following story: "A boat's crew were employed on Hall's Island, when one of the crew, left to take care of some produce, saw an animal whose voice was even musical. The sailor had lain down, and about ten o'clock he heard a noise resembling human cries; and as daylight in these latitudes never disappears at this season, he rose and looked around; but, on seeing no person, returned to bed; presently he heard the noise again; rose a second time, but still saw nothing. Conceiving, however, the possibility of a boat being upset, and that some of the crew might be clinging to some detached rocks, he walked along the beach a few steps, and heard the noise more distinctly, but in a musical strain. Upon searching round he saw an object lying on a rock a dozen yards from the shore, at which he was somewhat frightened. The face and shoulders appeared of human form, and of a reddish colour; over the shoulders hung long green hair; the tail resembled that of the seal, but the extremities of the arms he could not see distinctly. The creature continued to make a musical noise while he gazed about two minutes, and on perceiving him it disappeared in an instant. Immediately when the man saw his officer, he told this wild tale, and to add weight to his testimony, (being a Romanist,) he made a cross on the sand which he kissed, as making oath to the truth of his statement. When I saw him, he told the story in so clear and positive a
