Bostrychia vaga, in the cold cKmate of Kerguelen's Land, may be traced from rocks and stones, about high-water mark, to a considerable distance inland. The tips of its threads are often curled, which makes them peculiarly- apt to be entangled with other plants. Though Basya elegans is equally common in America and southern Eiu-ope, while its near relative, D. villosa, abounds in Van Diemen's LaOd, the European D. coccinea is not known on the eastern North American coast; and its nearest ally is found on the Western Pacific shores, at Puget's Island, from whence it was brought by Captain Wilkes's expedition. Rytiphlcea is a rare inhabi- tant of our southern coasts. The genera are far more abun- dant in the southern than in the northern hemisphere. Eleven genera only occur on the eastern coast of North America, including Chondria, and some of them are sub-tropical, while in the Southern Ocean there are at least twenty-three. Amansia, Alsidium, Acanthophora, and Digenea, are. Fig. 49. Polyzonia cuneifolia, Mont., with sticMdia, conceptacle, and spores, magnified. From specimens commumcated by Dr. J. D. Hooker. unknown upon our coasts, and delight in a warm climate. They occur, therefore, in such tracts as the Ked Sea; whUe, on the contrary, Odonthalia is a genus of high latitudes. Though so common in some parts of the Scottish coast, it is wholly.
