Mus musculus 

 House Mouse, Raton de Casa 



The house mouse was indigenous to the Old World, perhaps being found 

 originally through much of central Asia from the Mediterranean to China. It is 

 now a commensal that has followed humans throughout much of the world. 



We captured only two house mice at 2,600 m during the survey. The adult 

 female weighed 14.7 g, the adult male weighed 14.3 g and had testes measurements 

 of 7x4 mm. 



Specimens examined (2)— 2 km N, 0.5 km E of Sacramento, 2,600 m [1 male, 

 1 female, UNA].
