In one specimen the increase is due to twinning. 
Three specimens with more than the normal number of genital sacs. 
One with six genital sacs and six oral arms. 
One with five genital sacs and five oral arms. 
One with three genital sacs and three oral arms, and the tentaculocysts 
arranged thus : — 
Perradial 3.2.2. 
Interradial 0.2.0. 
Ten Tentaculocysts. {Fifty-tiuo specimens.) 
Perradial 2.2.1.1. 
Interradial 1.1.1.1. 
Nineteen specimens have an extra tentaculocyst in adjacent quadrants. 
Perradial 2.1.2.1. 
Interradial 1.1.1.1. 
Seventeen specimens have an extra tentaculocyst in opposite perradii. In one 
specimen the increase is due to twinning which occurs in the opposite perradii.

Interradial 1.1.1.1.1.1. 1.1.1.0.1.1. 
Two specimens with five genital sacs and five oral arms. Radial canals 
and tentaculocysts arranged thus : —

Eleven Tentaculocysts. {Nineteen specimens.) 
Perradial 2.2.2.1.
