the tentacles, especially those which were on the in- 
ferior side, were occupied with more or fewer ova, some 
having fifty or more, others half-a-dozen, others one or two. 
In each case they were rolling up the interior of the ten- 
tacle from the general cavity, and coursing to and fro under 
the influence of the lining cilia, sometimes accumulating 
temporarily at the tip, but never, so far as I saw, discharged 
there. 
On looking at the mouth, I perceived that the gonidial 
tubercles of one angle were brought into contact with those 
of the opposite angle, dividing the mouth into three tem- 
porary orifices, two lateral and one central. The lateral 
orifices, however, were at right angles to the ordinary line 
of extension. Through each of these lateral orifices ova 
were issuing, somewhat slowly, with an even motion evi- 
dently ciliary, for the most part not in contact with the 
sides of the tube, but coming up through its dark centre. 
As each came into view, and deliberately rolled over the 
edge of the orifice, it streamed across the disk, and over the 
face of the expanded tentacles, carried clear of all by means 
of the ciliary currents of these parts. The ova closely fol- 
lowed each other, generally in single file ; but occasionally 
two, or even three, were slightly agglutinated together. 
Perhaps on an average about three or four in a minute 
issued, but with many lengthened interruptions of the 
continuity. 
The process of egg-discharge did not continue long after 
I began to watch it ; though tlie accumulations remained 
in the tentacles. The next morning, those that had been 
deposited were for the most part disintegrated, resolving 
into an undefined mass of minute cells. A few only here 
and there retained their outline. During the next day or 
two, especially in the night, a few more were discharged, 
which were a little larger than the former, averaging .0060
