The development of the Palinuridiae seems to be very peculiar. Claus
found in the ova of the Spiny Lobster (Palinurus), embryos with a
completely segmented body, but wanting the appendages of the tail,
abdomen, and last two segments of the middle-body; they possess a single
median and considerably compound eye; the anterior antennae are simple,
the posterior furnished with a small secondary branch; the mandibles
have no palpi; the maxillipedes of the third pair, like the two
following pairs of feet, are divided into two branches of nearly equal
length; whilst the last of the existing pairs of feet and the second
pair of maxillipedes bear only an inconsiderable secondary branch.
Coste, as is well known, asserts that he has bred young Phyllosomata
from the ova of this lobster--a statement that requires further proof,
especially as the more recent investigations of Claus upon Phyllosoma by
no means appear to be in its favour.
The large compound eyes, which usually soon become moveable, and
sometimes stand upon long stalks even in the earliest period, as well as
the carapace, which covers the entire fore-body, indicate at once that
the position of the larvae hitherto considered, notwithstanding all
their differences, is under the Podophthalma.
