rtion of a species of Diphyes,
the same I had found on the 13th of November 1837 in south latitude 30
degrees 7; east longitude 100 degrees 50 minutes 10 seconds. The total
length of this was 0.5 inches.

Caught also two minute animals resembling a species of shrimp (Penaeus);
colour of both pale blue. The tail of the largest when examined in a
microscope precisely resembled in appearance the fin of a fish. I did not
examine the smaller one. Dimensions of the largest:

Total length 0.2 inches.
Length of feelers 0.15 inches.

Of smallest:

Total length 0.13 inches.

When put into eau-de-cologne these animals changed to a pink colour.

June 17. South latitude 29 degrees 19 minutes; east longitude 40 degrees
19 minutes.

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.*

June 23. South latitude 32 degrees 53 minutes; east longitude 29 degrees
45 minutes 15 seconds.

We for the first time saw Cape Pigeons and the Albatross.

June 27. ) South latitude 35 degrees 41 minutes; east longitude 25
degrees 13 minutes 20.
June 28. ) South latitude 35 degrees 15 minutes; east longitude 23
degrees 26 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.

June 29. South latitude 35 degrees 31 minutes; east longitude 22 degrees
20 minutes 30 seconds.

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,
