The Isopholidce (Eugiiathidce) differ from the families last named in the large pike-like mouth with strong teeth. The mandibular suspensorium is inclined backwards. The body is elongate, the vertebrae forming incomplete rings; the dorsal fin is short with large fulcra. Isopholis dentosus is found with numerous other species in the British Triassic. Caturus furcatus is especially characteristic. Fi

Ptycholepis marshi occurs in the Connecticut valley. The MacrosemiidcB are elongate fishes with long dorsal fin, the numerous species being found in the Triassic, Jurassic, and Cretaceous of Europe. Macrosemius rostratus has a very high, continuous dorsal. Macropistius arenatus is found in the Cretaceous of Texas, the only American species known. Promi- nent European genera are Notagogus, Ophiopsis, and Petalopteryx. Intermediate â between the allies of the gars and the modem herrings is the large extinct family of Pholidophoridce, referred by W(?bdward to the Isospondyli, and by Eastman to the Lepi- dostei. These are small fishes, fusiform in shape, chiefly of.
