Upon these two days we were in a rapid current, which we entered on the morning of the 27th, and on neither could we see the slightest signs of any of the acalepha class; but on the 29th, on which day we experienced no current, we found the greatest abundance of these animals; it appeared as if they had collected in large quantities at the edges of the current; and on the western side of it we found many animals which I had not seen on the opposite one.

The specimens caught were a minute fish, 0.35 inch in length; colour, back and upper half of sides, deep indigo; belly and lower half of sides, silver colour.

Also two sorts of barnacles (Anatifa) which I got near the side of the vessel.
We caught today a great number of the animals (Glaucus) I have mentioned above as having been taken on the 17th of June, as well as on other occasions.

I observed these animals in the water, and found that their long silk-like antennae had, when uninjured, a length of five or six inches; they swim with the rounded part first, and the long antennae trailing after them like tails; the progressive motion is produced by introducing water into certain sacs, or cavities, and expelling it by a contraction of the muscles with great violence.
