Permian ostracodes of Kansas and Nebraska are fairly well known and include many excellent index species but the faunas of Texas and the Southwest have been little investigated. This paper is largely based on the study of material contributed by several collectors. Many new and distinctive species have been recognized but their formal description has not been attempted. After abrief consideration of ostracode environments, specific variation and evolutionary trends, this paper discusses the outstanding features of various faunas and their stratigraphic and geographic variations. Described species of index value are listed and undescribed species are briefly characterized so that they can be recognized by others working with these faunas. Certain broad correlations are indicated. This study has clearly shown that the Permian ostracodes include many excellent index species and their further investigation will certainly yield data of great value for stratigraphic correlation.
