One of the Falkland Islands is called Elephant Island, from the former abundance of Sea-elephants there; but Mr. Sclater informs us that when Lecomte visited it, it was “found to be quite deserted by this animal, which is said now to be entirely extinct in the Falklands, though its former abundance in certain spots is well known, and is further testified by remains of its bones and teeth met with on the shores, specimens of which were obtained and sent home.”—_P. Z. S._ 1868, p. 527. See Dr. Sclater’s previous statement, P. Z. S. 1868, p. 189.
