A species of animal (Alima hyalina ?) was caught resembling a scorpion,
having six legs, three on each side; the first pair of legs were provided
with claws, like a lobster; its tail exactly resembled that of a
scorpion; the sac or bag near the extremity of the tail was of a light
red colour, and it tried to strike with its tail, as if for the purpose
of stinging. Eyes pale blue, and prominent; body nearly diaphanous, with
pale red spots.

Total length 0.33 inches.
Length of body 0.20 inches.
Breadth across from eye to eye 0.13 inches.
Breadth of body 0.14 inches.

Several of the animals which I supposed to be the Velella of Lamarck, and
some of which had been caught on the 11th of November 1837 were also
found today. Caught also a species of animal which I had found on October
22 1837, in south latitude 37 degrees 44; east longitude 38 minutes; and
again on November 12 1837, in south latitude 30 degrees 11 minutes; east
longitude 100 degrees 31 minutes 30 seconds. It resembles in shape and
size a large grape.

Extreme length 0.5 inches.
Breadth 0.45 inches.
Total circumference round broadest part 1.30 inches.

Colour brownish blue; but there were round it twenty very narrow brownish
yellow stripes, equidistant from each other, and not quite reaching
either extremity of the animal.

June 16. South latitude 28 degrees 46 minutes; east longitude 42 degrees
3 minutes.

We caught an animal this afternoon somewhat resembling a shrimp
(Erichthus vitreus)* covered with a shield: we had caught a similar one
on the 12th of November 1837. From measurements taken from the living
animal the dimensions were:

Length from tip of tail to tip of spine, in front of head 1.15 inches.
Ditto of spine 0.23 inches.
Ditto from tip of tail to bottom of last scale 0.2 inches.
Ditto from tip of spear to end of shield 0.7 inches.

The temperature of the water at 6 P.M. was 71 degrees Fahrenheit; of the
air 74 degrees.

(*Footnote. See Illustration 8 volume 1.)

The shield was perfectly air-coloured and diaphanous, and extended for
some distance beyond the head and the upper parts of the body; the body
itself was of a pale delicate blue, and it threw a very light bluish
tinge upon the shield; the eyes were jet black, and placed at the end of
a tube like those of the lobster; the tip of the spear was of a light red
colour. Caught also this day the lower po
