Three Noteworthy Distribution Records for Oklahoma Fishes

cragini (Percidae) was seined from the Cimarron River at a site 7.2 km west of Plainview and upstream from US Highway 64 in Woods County (S7 T28N R20W IM). This collection extends the known range for this darter. This site is 72.4 km downstream from that of the previous collection record in the Cimarron River, which was 4.0 km south of the Oklahoma-Kansas state line on US Highway 283, in Harper County (S15 T29N R26W IM), Oklahoma. The present distribution of E. cragini in western Oklahoma includes the Cimarron River from 19.3 km northwest of Knowles, in Beaver County (S24 T6N R25E CM), on the county road to Mead, Kansas, to Plainview in Woods County. We previously collected 394 specimens from the Cimarron River and two major tributaries, Crooked and Horse Creeks in Beaver County (1). Both tributaries support small populations of Arkansas darters
