30th .-- Passed the island of Teor, and a group near it, which are very incorrectly marked on the charts.

Flying-fish were numerous to-day.
It is a smaller species than that of the Atlantic, and more active and elegant in its motions.

As they skim along the surface they turn on their sides, so as fully to display their beautiful fins, taking a flight of about a hundred yards, rising and falling in a most graceful manner.

At a little distance they exactly resemble swallows, and no one who sees them can doubt that they really do fly, not merely descend in an oblique direction from the height they gain by their first spring.

In the evening an aquatic bird, a species of booby (Sula fiber.) rested on our hen-coop, and was caught by the neck by one of my boys.
