The distribution of the common Hedgehog in Europe is pretty- 

 well known. In European Eussia the northern limit of its dis- 

 tribution descends eastward and reaches, in the St. Petersburg 

 government, "Wego, 61° N. lat., whilst in the Ural mountains it 

 does not go farther north than 59°, — e. g., in the Verkhotursk 

 district of the government of Perm, where the species is already 

 scarce. In Central and Southern Eussia and in the Caucasus this 

 Hedgehog is everywhere common and more or less numerous, being 

 found as well in forests and the steppes, together with E. auritus, 

 as in the hills, up to 8000 feet. In the Transcaucasus these Hedge- 

 hogs attain a very great size. 



We have but very scanty and little trustworthy data as to its 

 distribution in Asia. According to Pallas it is absent on the other 

 side of the Ural chain. But Sabaneieff ^ says that it is met with 

 on the eastern slope of the Ural and that, there, it increases yearly 

 in number. This author thinks that it is but recently that this 

 species has penetrated into the Trans-Ural, and that Pallas's state- 

 ment of its absence there is thus simply explained. Slowzoff 2 found 

 it in the government of Tobolsk ; Schrenck 3 and Eadde 4 in Eastern 

 Siberia ; but, according to Prof. Kastchenko, it is wanting in the 

 government of Tomsk. Schrenck (I. c.) distinguishes the Amoor 

 Hedgehog as a separate variety. Eadde (I. c.) does not find it 

 possible to distinguish the Daoorian Hedgehog from the common 

 one. It is difficult to come to any decided conclusion from the figure 

 given by the last-named author, but it looks as if the skull figured 

 on plate v. of Eadde's work did not belong to E. europcms, but 

 to some other species. According to Dobson, E. dealbatus 

 Swiuhoe, from Peking, scarcely differs from E. europceus. It is 

 therefore evident that our knowledge of the distribution of E. eu- 

 ropceus in Asia is in the hands of future explorers.
