DESCRIPTION OF A NEW LEMMING MOUSE FROM " 

 THE WPIITE MOUNTAINS, NEW HAMPSHIRE. 



BY EDWARD A. PREBLE. 



During the Litter part of June, 1898, I collected a few small 

 mammal.s near the village of Fabyans, in the White Mountains 

 of New Hampshire, a short distance west of the base of Mt. Wash- 

 ington. Among these specimens is a small Lemming Mouse, 

 at first suj)[)osed to be Stjnaptoiiri/sfatuus,'^ which it greatly resem- 

 bles externally. An examination of the skull, however, show^s 

 the animal to belong to Mlctomi/s, a subgenus hitherto unre- 

 corded from the eastern United States. f 



On comparing this specimen with the type of Synaptomys 

 {Midomys) inmiitus, it was at once apparent that it represented 

 an undescribed form, which may be characterized as follows : 



Synaptomys (Mictomys) sphagnicola sp. nov.
