We have however seen more Sea-jellies, Acalepha and Mollusca than before, and those of a much more beautiful kind.

Thus nature has made up for the deficiency of one tribe of animals by the profuseness with which she has distributed another.
November 18.

Latitude 26 degrees 57 minutes south; longitude 105 degrees 22 minutes east.
We caught a crustaceous animal (Phyllosoma, see Illustration 11) which was perfectly transparent; it was furnished with twelve legs on what I considered the hinder part of its body, and four antennae in front, which have their tips of a bright pink colour, and two eye peduncles by their side, which terminate in little bags containing some blue matter (their eyes).

It was furnished also with two legs underneath.

These are just shown in the figure near the centre of the body, and between those underneath the insect there was a slight projection, with two little lumps on each side.
