338 MR. R, BROWN ON THE MAMMALS OF GREENLAND. [May 28, 



the dog the vicinity of man's dwellings, and the Hare the land 

 generally, while the Fox keeps more by the shore, but not in the 

 sea, and rarely ventures out on the ice-fields ; (p) 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 Ba}^, 

 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. 



(2) 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 Ce- 

 tacea, I have erected a division for temperate Europe, comprehend- 

 ing 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 {C) 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 

 straygler, seen within that division. For instance, Balcena 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 M'^alrus as regular 

 members of the British fauna. On the other hand, I need scarcely 

 say that when I put au animal into any division I do not thereby
