and steppe is as definitely commenced by the Gerbils and Mole-rats, as thepolar Fauna is in the north by the Lemmings. All the three species ofSpalax established by Nordmann occur in the Ukraine , and belong collec-tively to Sp. typhlus. If in the north we feel inclined to adopt the Dwinaas 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 ofthe Black Sea , and beyond the mouth of the Dniepr ranging westward, beplaced to the account of Asia .

In this extremely interesting German Report a list is contained at p.2S9 of the Mammalia , Birds, and Fishes observed by the traveller, with hereand there special observations concerning them. In Tamirland two speciesof Lemmings were observed; concerning these we shall make more detailedmention further on. An. asconomus occurred frequently as the only speciesof this genus at the Boganida (71 j°), but was absent at the riverTamyr in 73°northBr. Arv. amphibius prevails like an epidemic pest at Jenissei and theLena, ranging as far as the cultivation of field and garden crops extends ; yetit goes beyond this limit to Jenissei at 70°. Mus musculus approaches closer tothe Polar circle. Sciurus vulgaris roams among the fir-trees to their utmostlimit. Sorex-araneus and another, as yet undetermined, species, were cap-tured under 71 j°. Cams lagopus and C. lupus range as far north as Reindeer .Mustela sibirica disappears first within the polar circle. TJrsus arcios andGulo borealis make expeditions in the Tundra . The Reindeer annually setout on great excursions. The Seal that occurs in the gulfs is probablyPkoca barbata.
