Mammals Jru Hi Lahc Edward, Quebec. 49 



and it appeared to be confined to the forest. I hunted in vain the marshy- 

 spots and alder swamps and the cleared tields, places M. pennsylvanicus 

 would have delighted in, ])at found no trace of any Microtus there, and 

 trapping in such localities yielded nothing but shrews. We caught only 

 eight exanii)les of M. fontigenus. 



Microtus chrotorrhinus (Miller). Rufous-nosed ^leadow Mouse. 

 9 specimens. 



This beautiful little inhal)itant of the deep spruce forest was not com- 

 mon. I consider it one of the rarest of our small mammals. It is easy to 

 catch, and a day or two of traj^ping in any place is usually sutticient to 

 capture all that are there. M. chroforrhinus is apparently wholly diurnal. 

 On account of the depi'edations of shrews I visited our tra]js regularly 

 twice a day — once at daylight in the morning and again just before dark. 

 I never found a chrolorrhinus on any morning visit. Although these 

 specimens were taken nearly three hundred miles north of the type 

 locality (Mt Washington, New Hampshire), they are in every way tyi)ical 

 and show no approach to jl/. xanthorjii.athus. 



Fiber zibethicus (L.) IMuskrat. 9 specimens. 



Exceedingly abundant on all the marshy^ sliores of the lakes and rivers. 

 We set a line of sixteen traps one afternoon and on visiting them next 

 morning found fourteen muskrats. One traji I set on a floating log that 

 lay across a little brook where it emptied into Lake Edward and c-aught 

 a muskrat in it everj' night during our stay. 



Evotomys gapperi (Vig. ). Red-backed Mouse. 36 specimens. 



The commonest small mammal at Lake Edward. The red-backed 

 mouse of this region is the small, dark-colored form of the spruce belt, 

 true gup2)eri. 



Evotomys fuscodoi sails Allen. Dusky-backed mouse. 4 specimens. 



Apparently this little known Evotomi/ft was rare, four examples being 

 all we caught. These were taken in two localities al)Out three miles apart 

 and two in each place. In both places they were caught among loose 

 boulders on side hills covered by moss and overgrown by spruce, fir, and 

 white birch. 



Peromyscus canadensis abietorum subsp. nov. Hudsonian AVhite- 

 footed Mouse. 4 specimens. 



Type No. 2205, coll. of E. A. and O. Bangs, female adult, from James 

 river. Nova Scotia. Coll. l)y 0. H. Goldthwaite, August 8, 1894. Total 

 length, 200; tail, 103; hind foot, 20 (measured in flesh by collector). 



General characters. — Similar to Peromyscus canadensis (Miller), from 

 which it differs in being a uniform dark gray above in both young and 

 adult, never showing the russet and yellowish shades of old examples of 

 P. canadensis.
