Hoy* states that this animal moves very slowly upon land, but is vary 

 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.
