During July 2011 we collected an adult striped mullet (Mugil cephalus) from the upper White River in the Ozark Plateau of Arkansas. This is the first record of the species from the upper White River drainage; there is one record from the extreme lower portion of the White River where it drains into the Arkansas River. Eight other previous records of M. cephalus from the state include those from the lower Arkansas, lower Mississippi, upper Ouachita, and Red–Sulphur rivers. The species is listed as S1 (critically imperiled) in the state by the Nature Conservancy.
