A contribution to American thalassography : Three cruises of the United States Coast and geodetic survey steamer "Blake", in the gulf of Mexico, in the Caribbean sea, and along the Atlantic coast of the United States, from 1877 to 1880. Blake (Steamer); Marine animals -- Atlantic Ocean; Marine sediments. 30 THREE CRUISES OF THE "; places it in 1,500 fathoms. Most of the specimens known have been collected at the surface, and there seems to be a reasonable probability that this genus inhabits intermediate depths, since mid-depth fishes only have been found in its stomach. The gurnards have also representatives in deep water, if the remarkable new genus Hypsicometes is one of its members. This has been obtained both by the " Blake ' and by the " Al- batross " at various depths from 68 to 324 fathoms, and four species of the family touch the hundred - fathom line or go below it. The Agonidse are represented in 324 fathoms by one species of Peristedium (Fig. 209), remarkable for its branching barbels,. Fig1. 209. — Peristedium longispatha. About -|. and three others found between 140 and 300 fathoms, — all the result of recent American explorations. It is worthy of note, that the characteristic abyssal families are apparently offshoots of free-swimming species of active hab- its, which have, in the course of time, become gradually accli- mated in the depths of the sea. Their approach to great depths would appear to have been in vertical lines, rather than upon the slopes of the ocean bottom. One of the most aberrant types, Notacanthus, was obtained by the " Challenger " from a depth of 1,875 fathoms. N. phasga- norus was taken from the stomach of a shark killed on the Grand Bank of Newfoundland. Many members of the group of Pediculati are often met with swimming on the surface. They are species whose habits seem to have become modified to those of deep-sea fishes, while they ap- parently retain the characteristics
