Extinct Muridce. Species of Mus, Cricetus, Arvicola, and 

 My odes, occur in the Post-Pliocene deposits of Europe ; Arvicola, 

 Meriones, and the extinct genus Cricetodon, with some others, in 

 the Miocene. 



In North America, Fiber, Arvicola, and Neotoma, occur in caves ; 



1 Myospalax has hitherto formed part of the next family, Spalacidse ; but 

 a recent examination of its anatomy by M. Milne-Edwards shows that it 

 belongs to the Muridse, and comes near Arvicola.
