Macrurus Bairdii and Phycis Chesteri (Fig. 204) are the two most common fishes of the continental slope, where they occur in immense numbers, and breed at depths varying from 140 to 500 fathoms. The family Bregmacerotidae, hitherto known only through a single species, a native of the Indian Ocean, appears adapted to living at considerable depths. The discovery by the " Blake ' of a species (the long-finned Brcymaceros atlanticus} (Fig. 205). Fig. 205. — Bregmaceros atlanticus. of this old-world genus in the Gulf of Mexico, at a depth of 305-390 fathoms, is very interesting to ichthyologists. Certain groups of the blennies, gobies and the like, often send stragglers down to the lesser abyssal depths. They are forms with more or less elongate bodies, and low, feeble vertical fins, adapted neither to free swimming nor to the pursuit of prey at the surface. They are, in fact, bottom feeders, somewhat slug- gish in habit, and usually live among stones and hide in crevices ; while, as a rule, fishes like the perch, the sea-bream, and the mackerel, belonging to groups with compact, short bodies, pow- erful fins, and boldly predaceous disposition, do not descend to great depths, and do not wander far from the coast waters. The Berycoidea, the first group of bony fishes to appear upon the geological horizon, occurring early in the cretaceous, are repre- sented in the deepest dredgings of the " Albatross " (2,949 fath- oms) by a species of Plectromus. (Fig. 206.) The Norwegian deep-sea expedition found a species of Beryx, and Beryx spl en- dens, a magnificen
