In a kinesis, an organism is stimulated to movement by a particular stimulus 
but the movement is in no particular direction.  They just keep moving until the 
stimulus is no longer present.  In a taxis, the movement in response to the 
stimulus is directional.  They move in a direction that is related to location of 
the stimulus (for example, moving in the direction of or away from a light).  I 
am indebted to James E. Mazur for the clarity of his explanation in the 3rd 
edition of Learning and Behavior published in 1994 by Prentice-Hall.  He also 
provides some good examples.

Hope this helps,

Rick
