The 3000 specimens taken in 1898 show that 2'4 p.c. have more or less than 
the normal number (four) of genital sacs. The I'ange of variation is from 2 to 10, 
and most of the specimens show an increase in number (Table VII.).

Thei'e is a perfect correlation between the number of genital sacs and the 
number of oral arms, and I have not found any exceptions; a specimen with six 
genital sacs has always six oral arms. 
There is not a perfect correlation between the number of genital sacs and the 
number of radial canals and tentaculocysts, though a decrease in the number of 
genital sacs is usually accompanied by a decrease in the number of radial canals 
and tentaculocysts, and an increase by an increase in the number of the radial 
canals and tentaculocysts. 
In the 3000 adults 21 '1 p.c. show a vaiiation in the number of tentaculocysts 
and 2'2 p.c. of these have an abnormal number of genital sacs. But the variation 
in the number of genital sacs has a considerable effect upon the numeiical variation 
of the tentaculocysts. Only four specimens out of 72 with an abnormal number of 
genital sacs have eight tentaculocysts. 
The adults collected in 1894 (383 specimens) showed 2-08 p.c. with an abnormal 
number of gen'ital sacs.
