XV. Magellanic Province. 

 This region iucludes the coasts of Tierra del Fuego, the Falkland Ids, 

 (Malviuas) and the Mainland of South America, from P. Melo, on the east 

 coast, to Concepcion, on the west. It is described by M. D'Orbigny and 

 Mr. Darwin (Journal, p. 177 et seq.). The southern and western coasts are 

 amongst the wildest and stormiest in the world ; glaciers in many places 

 descend into the sea, and the passage round Cape Horn has often to be made 

 amidst icebergs floating from the south polar continent.* The greatest tides 

 in the straits amount to 50 feet. "In T. del Fuego the giant sea-weed [Macro- 

 njstis pi/rifem), grows on every rock from low-water mark to 45 fathoms, 

 both on the outer coast and within the channels ; it not only reaches up to 

 the surface, but spreads over many fathoms and shelters multitudes of marine 

 animals, including beautiful compound Ascidians, various patelliform shells, 

 Trochi, naked mollusca, cuttle-fish and attached bivalves. The rocks, at low- 

 water, also abound with shell-fish, which are very different in their character 

 from those of corresponding northern latitudes, and even when the genera 

 are identical the species are of much larger size and more vigorous growth."t

+ Shell-fish are here the chief support of the natives as well as of the wild 

 animals. At Low's harbour a sea-otter was killed in the act of carrying to its hole 

 a large Volute, and, in T, del Fuego, one was seen eating a cuttle-fish. (Darwin.)
