Hubbs and Lagler (1947:66) characterize the habitat of this species as clear creeks of limestone uplands. There are numerous records of the bigeye shiner from extreme eastern Oklahoma. It has been reported as far west as Beaver Creek in Osage County, Oklahoma. Beaver Creek originates in Cowley County, Kansas, near the origin of Cedar Creek and Crab Creek. Drought had left a few pools of water in Beaver Creek in Kansas at the time of my survey. The fish-fauna seemed sparse and _N. boops_ was not among the species taken. Of interest in considering the somewhat isolated occurrence of the bigeye shiner in the Flint Hills area of Kansas is a record of it by Ortenburger and Hubbs (1926:126) from Panther Creek, Comanche County, Oklahoma, in the Wichita Mountain area of that state. #Notropis buchanani# Meek: Stations G-1, E-4 (C-131). At station G-1 the ghost shiner was taken in small numbers in the shallow end of a long pool (150 x 40 feet.) The three individuals taken at station E-4 were in an isolated pool (50 x 510 feet) averaging 1-1/2 feet in depth. Water was turbid, and warm due to lack of shade. The habitat preferences of this species and of the related species _N. volucellus_ have been described as follows by Hubbs and Ortenburger (1929b:68): "It seems probable that _volucellus_ when occurring in the range of _buchanani_ occupies upland streams, whereas _buchanani_ is chiefly a form of the large rivers and adjacent creek mouths." The results of this survey and impressions gained from other collections, some of which are unpublished, are in agreement with this view. A collection on the Verdigris River at Independence, Kansas, directly downstream from the mouth of the Elk River, showed _N. buchanani_ to be common while _N. volucellus_ was not taken. At station E-5 upstream from E-4, however, _N. volucellus_ was taken but _N. buchanani_ was not found. In the upper Neosho basin, Cross (1954a:310) took _N. volucellus_ but not _N. buchanani_. Other collections have shown _N. buchanani_ to be abundant in the lower Neosho River in Kansas. Moore and Paden (1950:85) observe that _N. buchanani_ was found only near the mouth of the Illinois River in Oklahoma and was sharply segregated ecologically from _N. volucellus_ that occupied a niche in the clear main channels in contrast to the more sluggish waters inhabited by _N. buchanani_. #Notropis camurus# (Jordan and Meek): Stations C-3, C-4, C-5, C-6, C-7, C-8, C-9, C-10, C-11, C-12, C-13, E-1, E-5 (C-131). Highest concentrations of the bluntface shiner were found close to the mouths of two tributaries of Big Caney River: Rock Creek and Otter Creek. On Rock Creek (Station C-4) this shiner was abundant in a shallow pool below a riffle where water was flowing rapidly. Many large males in breeding condition were taken (June 3). The species formed 20.2 per cent of the fish taken.
