712 The American Naturalist. [August, 
Though there is no evidence that the male and female states may 
normally succeed one another in the same animal, yet when this, appar- 
ently, was the case in one specimen operated upon by Braem, we are 
not justified in regarding this is as a result of the operation or as in any 
way connected with it, since it may be that it would have taken place 
under the normal conditions. Moreover, and this is more important, 
the animal full of eggs may very well have been a hermaphrodite from 
the first, and have merely re-absorbed2its*ova under the stress of re- 
generation, so that we know nothing as to any real change from female 
to male in this case.
