Evermannella {Odontostontiis, the latter name preoccupied) and Omosudis are the principal genera. The Paralepidm are reduced allies of Plagyodus, slender, silvery, with small fins and fang-like jaws. As in Plagyodus, the adipose fin is developed and there are small luminous dots. The species are few and mostly northern; one of them, Sudis ringens, is known only from a single specimen taken by the present writer from the stomach of a hake (Merluccius produc- tus), the hake in turn swallowed whole by an albacore in the Santa Barbara Channel. The Sudis had been devoured by the hake, the hake by the albacore, and the albacore taken on the hook before the feeble Sudis had been digested. Perhaps allied to the PlagyodontidcB is also the large family of EnchodontidcB, widely represented in the Cretaceous rocks of. Fig. 366.—Eurypholu sulcidens Pictet, restored. Family Enchodontidw. Upper Cretaceous of Mt. Lebanon. (After Woodward, as E. boissieri.) Syria, Europe, and Kansas. The body in this group is elongate, the teeth very strong, and the dorsal fin short. Enchodus lewesiensis is found in Mount Lebanon, Halec sternhergi in the German Cretaceous, and many species of Enchodtis in Kansas; Cimolichthys dims in North Dakota. Remotely allied to these groups is the extinct family of DercetidcB from the Cretaceous of Germany and Syria. These are elongate fishes, the scales small or wanting, but with two or more series of bony scutes along the fianks. In Dercehs scutatus the scutes are large and the dorsal fin is very long. Other genera are Leptotrachelus and Pelargorhynchus. Dr. Boulenger places the DercetidcB in the order Heteromi. This is an expression of the fact that their relations are still unknown. Probably.
