Oceanography. GENERAL BIOLOGY 745 macrorhinus indicus, cm. long. So few of these were captured that I cannot attempt to define their vertical dis- tribution. These instances suffice to show that in the ocean the vertical distribution of young stages varies greatly in different species. Certain forms pass the whole of their life-cycle in deep water beyond 500 metres ; others live in deep water only in the adult stage, or at least spend their early life in the upper water-layers ; others, again, pass the whole of their life in certain clearly defined intermediate layers ; while others live in the surface waters all their lives. All these groups are holopelagic forms, but we meet with a group of genuine deep-sea fishes,.
