MAMMALIA. 



and steppe is as definitely commenced by the Gerbils and Mole-rats, as the 

 polar Fauna is in the north by the Lemmings. All the three species of 

 Spul a. r established by Nordmann occur in the Ukraine, and belong collec- 

 tively to Sj}. ti/plilus. If in the north we feel inclined to adopt the Dwiua 

 as the physio-historical limit between Europe and Asia, so must the pro- 

 vince of the uncultivated steppe in the south down to the northern coast of 

 the Black Sea, and beyond the mouth of the Duiepr ranging westward, be 

 placed to the account of Asia. 



Bericlit iiber die Expedition in das nordo'stliche Siberien 

 wahrend der Sommerhalfte des Jahres 1813, von Dr. A. 

 Th. v. Middeudorf, in the ' Bullet de la Classe Phys. Math, 

 de 1'Acad. de Petersbourg/ iii, p. 150. 



In this extremely interesting German Report a list is contained at p. 

 2S9 of the Mammalia, Birds, and Fishes observed by the traveller, with here 

 and there special observations concerning them. In Tamil-laud two species 

 of Jammings were observed ; concerning these we shall make more detailed 

 mention further on. Am. ceconomus occurred frequently as the only species 

 of this genus at the Bogauida (73 \), but was absent at the riverTamyr in 73 

 north Br. Aro. ampkibius prevails like an epidemic pest at Jenissei and the 

 Lena, ranging as far as the cultivation of field and garden crops extends ; yet 

 it goes beyond this limit to Jenissei at 70. Mas musculus approaches closer to 

 the Polar circle. Sciurus mdyaris roams among the fir-trees to their utmost 

 limit. Sorex-araneiis and another, as yet undetermined, species, were cap- 

 tured under 711. Canis larjopus and C. lupus range as far north as Reindeer. 

 Mttstela sibirica disappears first within the polar circle. Ursm arctos and 

 Gulo borealis make expeditions in the Tundra. The Reindeer annually set 

 out on great excursions. The Seal that occurs in the gulfs is probably 

 Phoca barbata.

 borantibus, Temminck and Schlegel, Dec. 2 and 3. 



The second Decad in the text, prepared by Temminck, extends to the 

 commencement of the description of Nycterenles viverrinus, at the same time 

 giving plates with figures, that were in arrear, of land mammalia. The 

 third Decad, of which Schlegel has been the author, is simply occupied with 

 the Seals and Whales found in the Japanic waters, and furnishes figures 

 also of these two divisions of Mammalia.
