Hudson suggests the following explanation of the ephippial eggs of 
Rotifers, namely, that they are not formed as a result of fertilization, 
but occur at the termination of the process of successive parthenogenetic 
reproduction of females, when the vigour of the ovary begins to fail, so 
that a single germ is no longer able to produce an embryo, but must be 
assisted by other equivalent germs which are separated off with it and 
enclosed in the ephippium. 
Refers to frequent presence of spermatozoa in the perivisceral 
cavity, and characterizes Plate’s idea as a “ strange theory but see 
Whitman (1).
