Temperature the same as the water, 65 degrees Fahrenheit.

We this evening caught several curious little animals (Clio ?) which when
taken out of the water appeared like small balls of the same matter as
that of which a slug is composed. Presently a little head peered out,
then the body expanded itself, and finally two little things like wings
were spread forth, formed of a fine membrane; they moved these very
rapidly, and swam with great velocity.

We caught several small crabs, and two kinds of shells, of a beautiful
purple colour. (Janthina exigua.) These were very small; I have preserved
several of them.

Figures 1, 2, and 3 represent different views of an animal (Salpa)
slightly electrical, that we caught this evening. Figure 1 is its
appearance, one side being up; Figure 2 when the other side is turned up;
Figure 3 is the side view of it.

I have never before seen one of the kind electrical. Temperature the same
