Agassiz.) The common flounder from Nova Scotia to Cape Hatteras is PseudojJhuronedes Ameri- canus of Fig. —GJoose-iish, one tenth natural size.—From Tenney's Zoology. Order 6. Pediculati.—The type of this order is the goose- fish. The name was given to the group from the long slender bones supporting the pectoral fins. The gill-ojien- ings are small and placed in axils of the pectoral fins. Lo- plduspiscatorius Linn., the goose-fish or angler (Fig. 423), has an enormous mouth, and swallows fishes nearly as large as itself. The head and fore-part of the body is very large ; the skin is naked, scaleless. Its eggs are laid in broad, ribbon-like, thin gelatinous masses, two metres long and half a metre wide, which float on the surface of the ocean. Order 7. Loplworanr-hii. —The tufted-gilled fish—such the name of the order indicates—have a fibro-cartilaginoiis skele-.
