Represents a little shell (Hyalea) which was caught this day.
Figure 2.

One of the tentacula of the animal I imagine to be the Physsophora rosacea.

The point which is seen obtruding at the base resembles a little nerve; it runs the whole way down the tentacula.
Figure 3.

A little shrimp-like animal (Erichthus vitreus) caught on the 14th November, latitude 29 degrees 26 minutes south; longitude 101 degrees 32 minutes east.

Its head was protected by a shield, such as is shown in the figure.
We caught this day several other Acalepha, two of which were of the wonderful genus DIPHYA.
