DESCRIPTION OF A NEW LEMMING MOUSE FROM 

 THE WHITE MOUNTAINS, NEW HAMPSHIRE. 



BY EDWARD A. PREBLE. 



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

 mammals 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 supposed to be Synaptomysfatuus* which it greatly resem 

 bles externally. An examination of the skull, however, shows 

 the animal to belong to Mictomys, a subgenus hitherto unre 

 corded from the eastern United States.f 



On comparing this specimen with the type of Synaptomys 

 (Mictomys) innuitw, it was at once apparent that it represented 

 an undescribed form, which may be characterized as follows : 



Synaptomys (Mictomys) sphagnicola sp. nov. 



Type No. 96543, cT adult, U. S. Nat. Museum, Biological Survey Collec 

 tion. Collected at Fabyans, New Hampshire (near base of Mt. Washing 

 ton), June 29, 1898, by Edward A. Preble. Original number 2402. 



* Described by Mr. Outram Bangs (Proc. Biol. Soc. Wash., X, p. 47, 

 1896), from Lake Edward, Quebec, and since recorded from Maine, New 

 Hampshire, and New Brunswick.
