Mammals from Lake 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 fields, places M. pennsylvanicus 

 would have delighted in, but found no trace of any Microtus there, and 

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

 eight examples of M. fontigenus. 



Microtus chrotorrhinus (Miller). Rufous-nosed Meadow Mouse. 

 9 specimens. 



This beautiful little inhabitant 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 trapping in any place is usually sufficient to 

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

 On account of the depredations of shrews I visited our traps regularly 

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

 I never found a chrotorrhinus 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 typical 

 and show no approach to M. xanthognathus. 



Fiber zibethicus (L.) Muskrat. 9 specimens. 



Exceedingly abundant on all the marshy shores of the lakes and rivers. 

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

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

 lay across a little brook where it emptied into Lake Edward and caught 

 a muskrat in it every 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 gapperi. 



Evotomys fuscodorsalis Allen. Dusky-backed mouse. 4 specimens. 



Apparently this little known Evotomys was rare, four examples being 

 all we caught. These were taken in two localities about 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 White- 

 footed Mouse. 4 specimens. 



Type No. 2205, coll. of E. A. and 0. Bangs, female adult, from James 

 river, Nova Scotia. Coll. by C. 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.
