Extinct Muridce. — Species of Mus, Cricetus , Arvicola , and 
Myodes , occur in the Post-Pliocene deposits of Europe ; Arvicola , 
Meriones , and the extinct genus Cricetodon y with some others, in 
the Miocene. 
In North America, Fiber , Arvicola , and Neotoma, occur in caves ; 
1 Myospalax Las hitherto formed part of the next family, Spalacidae ; but 
a recent examination of its anatomy by M. Milne-Edwards shows that it 
belongs to the Murid®, and comes near Arvicola.
