Light-brown, with ocellatcd spots. All the three are peculiarly destructive to the more valuable fishes. Some foreign ones have a slight difterence of character. The Sharks properly so called include all species with a produced snout, no nasal grooves, and with d, caudal lobe more or less forked. They form the genus Carc/iarias,—a numerous and notorious tribe, ^vith trenchant-pointed teeth, usually serrated in the margins ; the first dorsal before the ventrals; the second nearly opposite the anals. They have no spiracles; the nostrils are in the middle of the snout, and the last gill-opening extends over the pectorals. C. vid/joi-is, the "White Shark, is some- times twenty feet long, \Yith isosceles-triangular teeth, ragged at the sides, and the lower ones narrow points placed on ^vider bases ; these teeth in the mouth of such a fish forming weapons dreaded by all mariners. Found in most seas. [Its appear- ance on the British sliorcs has been mentioned, but it wants authentication.] C. vulpcx, the Fo-v- sliark, or Thresher.—Triangular teeth in both jaws; upper lobe of the tail as long as the whole body ; second dorsal and anal very small. C. gtau- cus, the Blue Shark, with curved-sided teeth above, inclining outwards, and straightcr ones be- low ; all ragged on the edges. Lamna, the Porbeagle, differs from a true Shark in the pyramidal snout, and the gill openings before the pec- torals. L. corniibica occasionally appears on the British coast, and its size has caused it to be mis- taken for the White Shark. L. moiiensis resembles the last, but has the snout shorter. Galeus.—Shaped like the Sharks, but with spira- cles and nn anal. G. vulgaris, the Tope, is found en the British shores. Miisteliis, resembles the former in shape, but has the teeth like a close pav
