Win;; the parent In shape, liut destitute of reproductive 
organs, and furnished with long tails, by which they are 
g repelled. These creatures, called Cercarice, escape by 
ursting through the Redia, and, after a free-swimming 
existence, penetrate the body of some other animal, their 
tails dropping off. They then become encysted, and . . . 
assume the adult form. Huxley, Anat. Invert., p. 179.
