M. Oscar Schmidt’s Remarks upon 
with a bud of medium age, which showed me the ventral 
surface, and the seminal vesicle gorged with spermatozoids. 
While I was taking a sketch of it with the camera lucida the 
whole twisted packet of spermatozoids contained in the vesicle 
was suddenly expelled by a violent contraction of the entire 
animal. The packet slipped rapidly forward behind the peri¬ 
stome, and appeared free in the cavity of the vestibule between 
the tentacles. After a few minutes the animal closed the 
tentacular curtain with a jerk ; the packet was then shot out into

expulsion the seminal vesicle, which was before so prominent, 
could only be distinguished with the greatest difficulty, it was 
so collapsed. As to the canal by which the seminal packet 
must have passed to reach the bottom of the vestibule, I found 
it impossible to distinguish it.” 
I have cited this whole passage (which is supposed to prove 
that a transfer of the semen outside the body takes place by 
means of the water) because I can furnish a very simple 
explanation of it. As early as 1875 I observed (and the 
drawing and notes upon it are now before me), in Loxosorna
