Some of the fish brought alongside were as beautiful as those celebrated in the Arabian tale, where “the fisherman, looking into the lake, saw in it fish of different colours--white, and red, and blue, and yellow;” indeed, they could not have been more beautiful than ours. In fact, all that are caught on coral reefs are remarkable for the great variety of their colours; but I must particularly describe one which bore the palm from all its splendid companions. It was about ten inches in length, and had for the basis of its colours an emerald green, with a head of a lighter shade of the same hue, which was banded longitudinally with stripes of rosy pink, and lines of the same beautiful tint were placed at intervals of an eighth of an inch transversely across its whole body, the scales on which were very small. The two pectoral fins were rosy pink in the centre, surrounded by a broad band of ultramarine. The short dorsal and ventral fins, which were continued to the tail, were of the same colours, the pink being inside. The tail was ultramarine outside, and the centre part of the fin of gamboge yellow: it had no anal fins. There was another extremely beautiful one of a pea-green colour: it appeared to be of the same genus as the former. The one streaked with red, with the poisonous fins, had firm flesh, and was rather pleasant to the taste; but in general their flavour and quality by no means equalled the brilliancy of their appearance. We placed the lovely emerald fish in a bucket of sea-water, but it soon turned on its back, and showed unmistakable signs of exhaustion. It seemed a sin to dine off so beautiful a creature. However, I suffered for it during the evening: I thought I was seized with cholera, and could scarcely get rid of the pains in the stomach; but Mr. Low did not feel any ill effects, so the fish may be harmless.
