Hoy* states that this animal moves very slowly upon land, but is very 
active in water. Insults offered to its mouth or eyes are resented by 
strokes of the tail. They are nocturnal in habits, and usually remain in 
concealment during the day. They have been observed in great num- 
bers in the Cathole, at Ann Arbor, Michigan, swimming vigorously on 
March 10th, and their eggs were found a few days later, after which they 
disappeared, passing into the woods and excavating burrows, in which 
they awaited their prey, being concealed, all but their heads. In the 
fall they wander about in search of a suitable place in which to hyber- 
nate, and at this time often stray into cellars during a wet night.
