It is throughout its extent gelatinous, transparent, and of strong consistency.
There is apparently a valve at its broadest extremity.
Length 1.1 inch.
Breadth in centre 0.1 inch.
Breadth at mouth of wide extremity 0.08 inch.
We have several times caught a triangular, transparent, gelatinous animal; it is 0.18 inch in thickness, and in the outer pulpy gelatinous mass there is an interior sac, and strong muscular bands are marked across this.

The sac is composed of three lobes, two of which have apparently no external opening, whilst at the end of the main lobe there is one which closes with a valve; through this I have seen them take in little animals, which reached no farther than the centre, from which the lobes radiate, when the sac became violently agitated, and made strong efforts to expel the foreign substance.

This animal was very sensitive, more particularly about the opening of the entrance.
We caught today the lower part of the species of Diphyes which we had found on the 13th November 1837, in 30 degrees 7 minutes south latitude, in the Indian Ocean.

This animal is thus distributed over a wide range.
We also found a very minute species of the animal similar to one which we caught on July 1st 1840.

Those we caught today were scarcely 0.05 inches in diameter.
