The following account of two specimens taken alive at Guernsey, in June, 1835, by F. C. Lukis, Esq., is extracted from Yarrell’s “British Fishes.” These creatures were kept about twelve days in a glass vessel, and their actions were equally novel and amusing. “An appearance of search for a resting-place induced me,” says Mr. Lukis, “to consult their wishes, by placing seaweed and straws in the vessel: the desired effect was obtained, and has afforded me much to reflect upon in their habits. They now exhibit many of their peculiarities, and few subjects of the deep have displayed, _in prison_, more sport or more intelligence. “When swimming about, they maintain a vertical position; but the tail is ready to grasp whatever meets it in the water, quickly entwines in any direction round the weeds, and, when fixed, the animal intently watches the surrounding objects, and darts at its prey with the greatest dexterity. “When the animals approach each other, they often twist their tails together, and struggle to separate or attach themselves to the weeds: this is done by the under part of their cheeks or chin, which is also used for raising the body when a new spot is wanted for the tail to entwine afresh. The eyes move independently of each other, as in the chameleon, and this, with the brilliant changeable iridescence about the head, and its blue bands, forcibly reminds the observer of that animal.” [Illustration: THE FLYING FISH OF THE OCEAN. (_Exocætus volitans._)] THIS fish has a slender body, a projecting under-lip, and very large and prominent eyes. The ventral fins are small, but the pectoral fins are so long and wide as to answer the purpose of wings, and aided by them the fish is enabled to rise out of the water, and support itself in the air. It must not be supposed, however, that the Flying-fish can soar like a bird; on the contrary, it can only spring from the water to a considerable height (sometimes as much as twenty feet), and fly about a hundred and fifty, or two hundred yards; most commonly, however, it does not rise above two or three feet from the water, and remains fluttering over the surface for about a hundred yards, when it again drops into its native element. There is another Flying-fish (_Exocætus exiliens_) in the Mediterranean. [Illustration: THE GURNARD. (_Trigla cuculus._)]
