Show 338 MR. R. BROWN ON THE MAMMALS OF GREENLAND. [May -8, the dog the vicinity of man's dwellings, and the Hare the land generally, while the Fox keeps more by the shore, but not m tne sea, and rarely ventures out on the ice-fields ; (ft) Circumarctic America and (y) Circumarctic Europe comprehend all the region about Greenland and south of the head of Baffin's Bay, down Davis s Strait, and other places south of the former limits, Hudson s Bay, Labrador, & c , on the one hand, and on the other the Icelandic seas and shores, the regions of Europe generally within or about the Arctic Circle. It may be called also subpolar, and has been formed to take in the distribution of some species of Seals and Cetacea. The two regions are about the same in zoogeography. (3) Circumarctic Asia comprehends similar limits on the Asiatic continent, and is made to take in the range of the Fox, Lemming, and a few other animals, which extend their range so far east and west. I have not thought fit to create in this table an Arctic division proper, limiting it by the arbitrary divisions of geography, divisions which, though necessary enough for the astronomical description of the earth, yet serve no purpose to the physical geographer in tracing the distribution of plants and animals over it. This division is comprehended under my circumpolar range, which ends on the seas adjoining Greenland about the head of Baffin's Bay. I have given its general limits there, as many species do not go beyond that barrier, and others do not come south of it. I am well aware that this may appear a somewhat loose way of expressing the limits of regions ; but at the same time the species the range of which these divisions are made to express are most wonderfully careless of the degrees, minutes, and seconds which the geographer may erect as their limits, and we can therefore only express their divisional boundaries in an equally elastic manner. I trust, however, that they are sufficiently intelligible. (e) To give the southern range of certain species of Seals and Cetacea, I have erected a division for temperate Europe, comprehending the British and Scandinavian seas ; and in the range of the same latitudes on the shores of the British provinces and the United States of America a ('() temperate American division. I have not, as in the circumarctic range, erected a division for temperate Asia, as I do not think there is a single species of Seal or Cetacea, found in the seas (and certainly no Mammals on the land) of temperate Asia, found in the corresponding seas of Europe and America, though, as several of the species are common to the circumarctic and circumpolar divisions of all three, some may yet be found. In preparing this table I have endeavoured to give the natural range of the species, and have not entered a species in any division because it has been, as an evident straggler, seen within that division. For instance, Baleena mysti-cetus, Beluga catodon, Monodon monoceros, and Trichechus rosmarus have all of them more than once found their way to the British seas, yet no zoogeographer would ever think of representing the Right Whale, the White Whale, the Narwhal, or the Walrus as regular members of the British fauna. On the other hand, I need scarcely say that when I put an animal into any division I do not thereby |
