N these days of concentration on fishes of relatively restricted areas, by means of regional checklists, circumscribed faunal works, and geographically limited revisions, one is apt to forget that many fishes are relatively unrestricted in distribution, and therefore cannot be said to belong to any one zoogeographic area. Although they may tend to interfere with attempts to give precise definition to the various zoogeographic regions, such species must not be overlooked, as they form an undeniable and interesting part of the general pattern of the dispersal of marine fishes.
