A Correlation betiveen the Radial Canals and the Tentaculocysts. 
The excellent condition of the large adults afforded a good opportunity of 
examining the radial canal system. The few figures given by Romanes and other 
observers show distinctly that there is a correlation between the radial canals and 
the tentaculocysts, and my obseivations confirm theirs. 
In the 1000 adult specimens I found that every tentacvdocyst (twinning 
excepted) had its own branched canal leading direct from the stomach, and 
always separated from the adjacent branched canals by a simple unbianched 
canal. By means of the canals the origin of the tentaculocj'st could be traced 
home to either the perradial or interradial system.
