SPREADING OF THE MAMMALIA. 6,3 



21. The family of Mice (Mws), Squirrels (Sciurus), 

 and Hares (Lepus), are found in every part of the 

 habitable globe. The common Hare (L. timidus) 

 occurs throughout Europe. The Varying Hare (L. 

 varidbilis) inhabits the Snowy Mountains of Green- 

 land, Lapland, Siberia, &c. The Alpine Hare is 

 peculiar to the Alps. The Rabbit (L. cuniculus}, 

 lives in the middle and warmer part of the Tempe- 

 rate Zone ; the Dwarf Hare (L. nanus) in North 

 America ; and the Brazilian Hare (L.Brasiliensis) in 

 Brazil. Of the Mice Genus, the Rat follows the 

 habitation of man in every direction ; except in the 

 cold countries, where they have the Lemmings (Mus 

 lemmus), as in the snow-line of Scandinavia. The 

 Root Mouse lives in Kamtchatka; the Hudson's 

 Bay Mouse in Labrador. The Mountain Rats, 

 which are related to the Mice, are inhabitants of the 

 Alps ; but sleep, during the winter, like the Hames-

 not natives of cold countries. Of the Squirrels, the 

 common one (Sciurus Europceus) spreads through- 

 out Europe, and Sc. Hudsonius throughout Labrador. 

 Some Flying Squirrels inhabit the colder countries 

 of the Temperate Zone; others, warm climates. 

 The Palm Squirrel (Sc. palmarum), and the Java 

 Squirrel (Sc. bicolor) in Java, are inhabitants of the
