UAJ I OCCASIONAL PAPERS of the u ^*s7r° v MUSEUM OF NATURAL HISTORY The University of Kansas Lawrence, Kansas NUMBER 90, PAGES 1-69 MAY 28, 1981 THE GENERA AND SUBGENERA OF DARTERS (PERCIDAE, ETHEOSTOMATINI) By Lawrence M. Page 1 Since 1955 the generic and subgeneric classification of darters has been largely the concept of Reeve M. Bailey (Bailey, 1951; Bailey, Winn and Smith, 1954; Bailey and Gosline, 1955). As future studies and data will alter the classification presented herein, so are changes in Bailey's classification offered on the following pages. All proposed changes are subgeneric; the greater stability in nomen-clature inherent in more inclusive genera argues for the continued use of Bailey's three-genus classification of darters rather than ele-vating some or all subgenera to generic status. More important contributions than the proposed changes are the morphological diagnoses of genera and subgenera incorporating characteristics ex-amined critically, either in the literature or during this study, on each species of darter treated herein.
