THE WOOD-TEREAPIN.

with radiating yellow Hnes ; it 
frequents fresh waters, and is 
sometimes called the Fresh- 
Water Terrapin ; hut being 
often met with in Avoods at a 
distance from water, the name 
given above has been be- 
stowed upon it. It is harm- 
less, but when irritated will 
snap at the offender. Found 
Irom Canada to Pennsjdvania. 
Muhlenberg's Tortoise, jE. 
Muklenberffii, is four inches long; shell

It thus appears that fifteen or tM^enty species of this genus are known and described in the 
United States, and, according to De Kay, including nearly all the known fresh-water tortoises 
in America ; it is probable that farther investigation will bring others to light, and doubtless the 
range of many we have noticed will prove to be more extensive than we have indicated.

able.

notherus. — This includes the Musk- 
Tortoise, 8. odoratus ; its length is
