Interradial 1.1.1 .1, 
the medusa having eight perradial tentacnlocysts and canals, four interradial 
tentaculocysts and canals, and eight adradial unbi'anched canals. 
A Detailed Account, giving the Position of the Tentaculocysts in the Specimens 
{Large Adults belonging to Series B) having more or less than the Normal 
Number. 
Four Tentaculocysts. (Two specimens.) 
Perradial 0.0.0.0. 
Interradial 1.1.1.1. 
One specimen with only four interi'adial tentaculoc^'sts. 
The interradial branched canals occupy the four quadrants. There are no 
adradial canals, but four simple unbranched canafs, perradially situated. It is 
probable that in this specimen the perradial canal system is absent and the simple 
canals, perradially situated, are tlie representatives of the adradial system removed 
from their proper position.
