trance into the receptacle or not. That they are not active while 
stored in the receptacle is shown by opening filled receptacles on 
dry slides. The sperm are invariably quiet, but immediately 
become active when sea-water is added. In specimens killed soon 
after copulation, sections show the sperm entering the receptacle 
in narrow streams and not spread out as one might expect them to 
be if the sperm were active (fig. 11). It was not possible to remove 
all the sea-water from living specimens in which the receptacles 
were being filled without causing disturbances in the vicinity of 
the reservoirs and that made it impossible to determine the normal 
condition of the sperm in transit from one to the other. In the 
sections that show sperm entering the reservoir the tails all point 
in the same direction, as would be the case if they were not swim- 
ming actively but were being moved by an outside force. The 
heads go first and the tails all trail behind. Swimming sperm 
usually move in all directions but there may be some directive 
cause that would account for their positions even if they are stored 
through their own activities. 
As previously stated, a female that is nearly ready to deposit 
her eggs can be told by her peculiar nervous movements and the 
way she manipulates her arms. Frequently the borders of the 
accessory nidamental glands, which are very red at this time, may 
be seen through the semi-transparent mantle and thus form a 
further indication that the eggs are nearly ready to be deposited. 
The nidamental and oviducal glands of such an animal are always 
somewhat, and frequently greatly, enlarged. Immediately after 
the eggs have been deposited these glands, while still large, are 
soft and flabby. 
As is well known the squid deposits her eggs imbedded in strings 
of a jelly-like substance which vary in size with the size of the ani- 
mal depositing them but which probably average about 8 mm. in 
diameter and 90 mm. long. The jelly consists of an inner mass 
that surrounds the eggs and a thick, rather tough but still jelly- 
like sheath that forms the outer covering. The inner jelly is se- 
creted inside the oviduct by the oviducal glands. The outer jelly is 
secreted by the nidamental glands and is apparently moulded into 
shape as it passes through the funnel. The accessory nidamental
