*9. C. cristata. The star nosed mole appears to be a very rare species within tho limits of 

 this State. I have seen but a single specimen. 



xl6 and *17. N. Pennantii, and M. Americana. The Fisher and Pine Martin undoubtedly have 

 a place in'our fauna, but I have not had an opportunity of examining spe'cimens other 

 than hunter's skins as found in market. 



*21. G. luscus. The "Wolverine is seldom found in the Lower Peninsula, having been nearly 

 exterminated. 



*27."D. Virginiana. A single specimen of the Opossum was killed in Genesee county last 

 season. The species is, however, frequently seen in the southern part of the State. 



*33. S. tridecem-lineatus. Tho striped Prairie Squirrel is very common in the southern 

 counties, but has not been known in the central parts of the State until within a few 

 years past. It is gradually extending its range northward, where the timber has been 

 removed and the land brought under cultivation. 



*35. C. Canadensis. At no very remote period the Beaver was found throughout tho State. as 

 is shown by the numerous remains of their dams in localities that are now deserted 

 by them. At present their range is confined to the northern part of the Lower Pe- 

 ninsula, where they are found in abundance on the head waters of nearly every 

 stream running into Lake Huron. At Alpena several hundred skins are annually 

 brought in from Thunder Bay river and its tributaries.
