Caught a specimen of Glaucus.
Total length 0.35 inches.
Colour down the back deep indigo blue; stomach bluish white; sides bluish white (silvery) like a frog; tail tapering to a point; its head resembled that of a frog, and when out of the water it sat on its tentaculae, and raised its head and the fore part of its body, moving its head (a) from side to side; the tentaculae were all so delicate that they fell off, it had apparently eight on each extremity; it belonged to the same family as the animal I caught on the 14th of November 1837, in south latitude 29 degrees 26 minutes; east longitude 101 degrees 32 minutes.*

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.
