This reef is of great extent, with all the varieties of coral, mud, and sand, and proved a most productive one.

A sketch of the distribution of the principal of its productions may be of interest to some.

Many kinds of fishes, Muraena, Diodon, Balistes, Serranus, etc.

are found in the pools among the coral blocks; the first of these, of bright colours variously striped and spotted, resemble water-snakes, and are exceedingly active, gliding through the interstices in the coral and hiding in its hollows--they bite savagely at a stick presented to them, and are by no means pleasant neighbours while wading about knee-deep and with bare arms turning over the coral which they frequent.

On a former occasion I had been laid hold of by the thumb, and the wound was a long time in healing.
Crustacea are also numerous; blue and green Gonodactyli leap about with a sharp clicking noise--legions of Mycteris subverrucata traverse the dry sands at low-water--and in the shallow muddy pools, dull green Thalamitae and Lupeae swim off rapidly, and smooth Calappae seek refuge by burrowing under the surface.
Of mollusca, two species of olive (O.Erythrostoma and O.leucophoea) were found on the sandy margin of the islet--several Cerithia and Subulae (S.maculata and S.oculata) creep along the sand flats, and, with some fine Naticae, and a Pyramidella, may be found by tracing the marks of their long burrows.
