Note on the Nephridium of Endoproctous 



Polyzoa. 



By A. Oka. 



In a paper published in the last number of this journal, I compared 

 the nephridium of Phylactolaematous Polyzoa with that of Endoprocta, 

 drawing the facts in regard to the latter group mainly from Joliet,* 

 who represents it as consisting of two short tubes opening into the 

 body-cavity by means of ciliated funnels. Being anxious, however, to 

 know how far these organs resembled each other, I cut sections of a 

 large number of Endoprocta obtained at Misald and studied them. I 

 soon found out, that the description of this organ given by the alcove 

 author was quite correct as far as the external form was concerned, but 

 tlie mode of termination of its free extremity was not correctly made out
