LARVAE op the EOLIDIDiE.
The development of the ova in the Eolididce is so entirely similar to what takes place
in Doris, that we do not think it necessary here to enter into the details which will be found
under the head of that genus. The coil of spawn in this family is generally more slender,
and the number of volutions greater than in the Dorididce; but in these respects there is
considerable variation in the different groups, as will be seen on referring to the plates of
species.
The larvae undergo only a very slight variation of form throughout the entire order.
For the purpose of showing the limits of this variation, we have here given a representation
of some of the most distinct forms in the family Eolididce, from which it will be seen how
very much they resemble each other. On account of their minuteness the natural size
could not be given; it must therefore be borne in mind that the largest of them are only just
visible to the naked eye.
