From the original preface: Probably no group of fossil organisms except the Foraminifera has received more active study during the past decade than the Ostracoda, partly because of their scientific interest but mainly because of their importance in economic geology. The oil geologist finds the ostracods especially useful because their small size enables them to escape destruction by the drill, and the excellent preservation of the carapaces, with more or less distinctly marked surfaces, permits more certain specific identifications. Moreover, they are less subject to the influences of lithologic changes; the same fauna may persist in a formation whether it be limestone, shale, or sandstone. Again, many species have short ranges, so that each formation has its characteristic fauna. Some, indeed, are long ranged, but these are mainly the simple, smoothshelled forms difficult of differentiation.
