exclusively South American laniily is really derived from Europe, 

 where it has lonu' been extinct. 



Family 09.— LAGOMYID^E. (1 Genus, 11 Species.) 



Tlie Lagoijiyidip, or pikas, are small alpine and desert animals 

 which range from the south of the Ural Mountains to Cashmere 

 and the Himalayas, at heights of 11,000 to 14,000 feet, and 

 nortliward to the Polar regions and the north-eastern extremity 

 of Siberia. They just enter the eastern extremity of Europe as 

 far as the Volga, but with this exception, seem strictly limited 

 to the third Palffiarctic sub-region. In America they are con- 

 fined to the Eocky Mountains from about 42° to 60' north latitude.

 Nearctic and Pahcarctic, but are also thinly scattered over the 

 Ethiopian and Oriental regions. In the Neotropical region they 

 are very scarce, only one species being found in South America, 

 in the mountains of Brazil and various parts of the Andes, while 

 one or two of the North American species extend into ^Mexico
