132 MICHIGAN SURVEY, 1905. 



much less rufous, and the gray color contrast these squirrels with those from 

 the Porcupine Mountains (var. loquax). 



Mr. Wood frequently saw squirrels feeding upon seeds taken from the 

 cones by first cutting away the lower scales. 



3. Peromyscus canadensis (Miller). Canadian White-footed Mouse. I 

 and III. Two specimens, both adult females, one from the camp clearing and 

 the other from the Lake Desor trail were determined by the U. S. Biological 

 Survey as of this species. Two immature males, from II, were doubtfully 

 referred to this species, also a male from III. Four specimens, of both 

 sexes, taken at II, are provisionally referred to this species. 



4. Fiber zibethicus (Linn.). Muskrat. II. A pair of muskrats were 

 taken along the creek through a cedar swamp, other specimens were seen 

 but not taken.

5. Lepus americanus Erx. Hudson Bay Varying Hare. II. Six speci- 

 mens were .taken among the conifers between August 18 and 22. The 

 pelage of three of the specimens is long and loose, the tips of the long hairs 

 on the back are white or very pale yellow; the white hairs give the head 

 a frosted appearence. These are young specimens. The pelage of the 

 other three is more compact, and black hairs are more conspicuous, the 

 upper part of the head is a pale yellowish brown. An adult female, No. 

 32131, is the largest specimen, and also the darkest; a black mid-dorsal band 

 is fairly distinct. The white outer margin of the ears is very wide and 

 distinct. The upper part of the hind legs is mottled with white and yellow 

 hairs ; long, scattered white tipped hairs occur on the end of the body above 

 the tail. 



The distinctness of the outer white ear margin varies in this series. The 

 large female, mentioned above, has very long white hair; the three speci- 

 mens first mentioned, have quite white hair, while in two others the 

 hair is yellowish white. 



It is interesting to note that these are a different variety from that found 

 in the Porcupine Mountains, on the south shore (var. virginianus) . This, 

 like several other members of the biota, shows the close affinities of the Isle 

 Royale types to the adjacent mainland rather than to the remainder of 

 Michigan. 



6. Lynx canadensis (Kerr). Canada Lynx. Mr. Wood made the follow- 

 ing note on lynx skins which he saw at the Washington Club House, at 

 Washington Harbor. " I saw two Lynx skins taken by Chas. Preulx during 

 the winter of 1903 and 1904. Preulx says that this is the only species he 

 has seen on the Island." 



7. Mustela americana Turton. Eastern Martin. "Mr. Preulx had 

 several martin skins which were taken during the winter of 1903-'04, 

 on the maple ridge, not far from Washington Harbor. These skins were 

 very dark brown with a few scattered white hairs, especially on the under 

 side." (Wood). 



8. Putorius vison (Schreber). Mink. II. Mr. Wood found a dead 

 specimen in a barrel sunk at a spring. Preulx reported it quite common 

 about the Harbor and along the streams. 



9. Putorius cicognani (Bonap.). Small Brown Weasel. Mr. Wood 

 reports that Preulx had about 10 skins, and said they were quite common. 



10. Putorius noveboracensis Emmons. New York Weasel. Preulx had 

 a number of large weasel skin& which probably belonged to this species.
