3-26 LAGOMYS PRINCEPS NOT A NEST-MAKER. 



not a trace of nest could I see, nor any evidence 

 of an attempt to make one. I soon after returned 

 again by the same trail. The snow having now 

 fallen to the depth of about six inches, completely 

 covering up the rocks and stones, all the animals 

 had disappeared; and although I searched most 

 carefully, there was not a hole or track in the 

 snow, to show they had ever left their quarters 

 to feed or wander about. 



As it was quite impossible a nest could have 

 been made in the interim, it is perfectly certain 

 they hybernate in holes without a nest ; whereas 

 Lagomys minimus, living at a much greater alti- 

 tude, makes a nest to sleep through the winter.
