Brookes, in his History of St.Helena (second edition page 24) says: "There are neither frogs, toads, nor snakes in the island." In the Isle of Bourbon there are neither toads nor snakes.

In the Mauritius likewise there are neither toads nor snakes, and only one species of frog, whilst the bones of the land tortoise (Testudo indica) are only found in a fossil state.
Also, the highest land in St.Helena is 2800 feet; in the Mauritius about 2900 feet (scarcely); and in the volcanic district of North-west Australia about the same height.

At sea.
We caught a great variety of shrimp-like animals; these little things when disturbed emitted a brilliant phosphorescent light.

We saw scarcely any gelatinous animals.
July 29.
Caught two small crabs (Nautilograpsus); these species have the power of swimming by means of the fringe-like fins with which their legs are provided.

Several other crabs were also caught; some with their eggs attached, and two varieties of shrimp-like animals with eggs.
