130 MICHIGAN SURVEY, 1905. 



(var. americanus) . The white outer ear margin is only feebly developed. 

 IV. 2. A young female was taken, Aug. 21, in the alders along Carp river. 

 In this specimen the rufous tints are very pronounced on the upper side 

 of the legs and on the pectoral region. The outer margin of the ear is of 

 a distinctly yellowish white color. 



15. Lynx ruff us (Gueld.). Bay Lynx; Wild Cat. IV. 2. A weathered 

 skull was found in the alder bushes along Carp river, by Ruthven. Trappers 

 reported this species common. 



16. Canis occidentalis Richardson. Gray Wolf. The trappers reported 

 them common. Near the Porcupines, during the winter of 1902-'03, a 

 trapper was reported to have been treed by a pack. Wolves are reported 

 to have killed many deer near the Porcupines, during the past winter of 

 1904-'05. 



17. Taxidba taxus (Schreber). Badger. Trappers reported that occas- 

 ionally specimens were found. 



18. Mephitis hudsonica (Rich.). Northern Plains Skunk. II. 3. Young 

 and three adults of both sexes were secured between July 15 and July 30, 

 in the clearing about -camp. They were very abundant. A large adult 

 male was taken, July 30, which weighed eight pounds. II. 2. Two specimens 

 were seen by Ruthven along the road through the hardwood forest in Septem- 

 ber, 1903. On the morning of July 15, Wood found a young skunk in a 

 trap, held fast by the foot. Another of about the same size was observed 

 running about the captive, making frequent attempts to liberate it by biting 

 the trap and pulling with its fore feet. 



The skunks found in the traps were not at all violent in their attempts 

 to escape and could easily be approached and killed with a noose. 



This is a northern plains and Rocky Mountain species. These northwestern 

 affinities suggest an origin from that direction, by way of Minnesota. 



19. Putorius cicognani (Bonap.). Small Brown Weasel. Near II. 2. 

 An adult female was taken along a corduroy road through the hardwoods 

 on Section 17. Dr. Merriam wrote in 1896, "It probably also occurs in 

 Northern Michigan and Wisconsin." (N. A. Fauna No. 11, p. 11). 



20. Ursus americanus Pallas. Black Bear. III. Fresh signs were 

 observed several times on the mountain top, where Allie reports that they 

 often came to feed upon the dwarf and low black blueberries. A cub was 

 observed here, August 5, by Allie. 



Trappers reported them quite common in the mountains. An adult 

 bear was killed, July 11, 1904, at Iron river, near the Porcupine Mountains. 



21. Sorex hoyi Bair^d. Hoy's Shrew. III. 5. A pair of adult specimens 

 were found in the aspen zone on the mountain on July 29, and August 2. 

 IV. 4. One specimen was taken, August 12, in the tamarack swamp. 



This is said to be the smallest North American mammal, and is without 

 doubt the smallest one in Michigan. 



22. Blarina brevicauda (Say). Large Bob-tailed Shrew. II. 2. Adult 

 shrews of both sexes were taken in the hardwoods during August. II. 3. 

 Three adult females were taken in the clearing. III. 5. Adults of both 

 sexes were taken in the aspen zone surrounding the mountain top. 



This shrew and the White-footed Mouse were the most common small 

 mammals in the mountains. 



. 23. Condylura cristata (Linn.). Star-nosed Mole. II. 2. A pair of 

 moles was taken, September 2, 1903, by Ruthven, in the hardwood forest, 

 on the mountain slope above the camp. This was about 800 feet above 

 lake level. The line of their tunnel was intersected by a cutting, at the base
