. Cuvier's animal kingdom : arranged according to its organization. Animals. Lamna, the Porbeagle, differs from a true Shark in the pyramidal snout, and the gill openings before the pec- torals. L. cornubica occasionally appears on the British coast, and its size has caused it to be mis- taken for the White Shark. L. monensit resembles the last, but has the snout shorter. Galeus.—Shaped like the Sharks, but with spira- cles and an anal. G. vulgaris, the Tope, is found on the British shores. Mustelus, resembles the former in shape, but has the teeth like a close pavement. Milavis, the Smooth Hound, is a British species. Notidanus, wants the first dorsal ; has six giU- , triangular teeth above, and like a ^'B- i-is—The Thresher, saw below. Two species inhabit the Mediterranean. Has the form of the Sharks, and spiracles, with the gill- openings nearly surrounding the neck ; its teeth are small and not notched. It is the largest of the True Fishes, being sometimes thirty-six feet long ; but it is a harmless fish. S. maximus, the Basking Shark, is found in the British seas. Centracion, has spiral teeth like pavement, and a spine before each dorsal. k'pinar, resembles Carcharias, but has spiracles ; no anal fin ; several rows of small trenchant teeth ; and a strong spine before each dorsal. S. acantheus, the Piked Dog-fish, is a British species. Cenirina, resembles the last ; but the second dorsal over the ventrals, and the short tail, give it a clumsy appearance ; its skin is very rough. Scymnus, the Greenland Shark, is more abun- dant in the Arctic seas, and is large and vora- cious; but is understood not to attack Man. Zygœna, forms a second genus. Like the Sharks in the body, but with the snout singu- larly produced, forming two pieces like a double- headed hammer, with an eye in the middle of each extremity. The species of the European seas grow to the length of twelve feet, [and we believe larger ones are met with in southern latitudes]. Squatina, the
