Having excepted out of these sixty-eight species the domestic animals, 

 and those concerning which the evidence is of a negative character, there 

 remain about fifty-eight, which we may consider to be the number belong- 

 ing to the " Mammal-fauna" of Amoorland, as far as we are at present 

 acquainted with it. Let us see, therefore, what deductions we can make 

 as to the general character of the Fauna of this country from these ele- 

 ments. As Dr. Yon Schrenck himself observes, our first remark will be 

 one of surprise at the ill-assorted neighbours which, in some instances, 

 seem to be brought together in Amoorland. A Bengal tiger, even with 

 so limited a knowledge of the geographical distribution of animals as we 

 might suppose such a carnivore to possess, must be rather surprised at 

 finding himself, as he swims across the Amoor, brought face to face with 

 the northern seals, Phoca nummularis, and P. barbata, and the White- 

 fish of the arctic seas (Delphinapterus leucas.) Neither can his wonder be 

 diminished, when, on crossing the narrow strait which separates the 

 island of Sachalin from the main, he is compelled to subsist nearly en- 

 tirely upon the flesh of the rein-deer ( Cervus tarandus), a beast only 

 found wild in Europe in the extreme north, and which will not live in 

 our Zoological Gardens, but which on this side of the great Continent 

 descends to the latitude of Paris. The little Polar Pika, or tailless hare, 

 is also met with in Amoorland, down to the latitude of 48°, while the 

 wild boar ranges northward beyond latitude 52°. But putting these 

 apparent anomalies aside for a moment, it is very instructive to observe 

 how similar in general characters the Fauna of Amoorland is to that of 

 Europe. The difference, taken at it greatest amount, is hardly more than 

 that of species. Out of the whole number of fifty-eight mammals of 

 Amoorland, as above recorded, no less than thirty-four seem to be iden- 

 tical with European species ; and most of the others belong to genera 

 which have European representatives. The nineteen species not found 

 in Europe appear to be the following: — 



Mustela sibirica, Lagomys hyperboreus, 



Enhydris marina, Antilope crispa, 



Canis alpinus, Moschus moschiferus, 



,, procyonides, Phoca nummularis, 



Felis tigris, ,, barbata, 



,, irbis, ,, ochotensis, 



Spermophilus Eversmanni, ,, equestris, 



Arvicola amurensis, Otaria ursina, 



,, saxatilis, Bakena australis.

 Of these, Enhydris, Moschus, and Otaria, belong to genera common to the 

 polar regions of Asia and America, and so perhaps show some relation- 

 ship of the Fauna of Amoorland to that of the more northern parts of 

 the New World. Of this, it must be recollected, Japan furnishes us 

 with further and more remarkable instances, — a second species of the 

 singular talpine genus Urotrichus* having lately been discovered in 



* Urotrichus gibbsii, Baird. Examples of this highly interesting Insectivore have
