SEXUAL ACTIVITIES OF THE SQUID Bot 
The egg strings are composed of two kinds of jelly. One kind 
is supplied by the oviducal gland and the other by the nidamental 
and probably accessory nidamental glands. The string is appar- 
ently molded into shape by passing through the funnel. The 
jelly is at first soft and sticky but soon becomes tough and loses 
most of its stickiness. 
From the funnel the egg string is drawn between the circlet of 
arms, where it is held two or more minutes. In sticking the 
string the female grasps some object with her arms and draws 
down tight so the string is evidently crowded against it. When 
she releases her hold the string is left sticking to the object. 
Fertilization evidently does not take place inside the oviduct. 
It doubtless may take place in the mantle chamber when sperm 
reservoirs are present there, and is known to take place while the 
egg string is held between the arms. The sperm are liberated - 
from the receptacle while the eggs are between the arms. 
Notwithstanding complications, the conditions of hectocotyl- 
ism shown by cephalopods need not be considered beyond the 
influence of factors of evolution.
