In many instances the logperch was taken over submerged gravel bars, often along the edges of the larger pools. At 8 of 13 stations where the logperch was taken, the golden redhorse was also found. At every station where logperch were found, _Notropis umbratilis_ was taken and _Pimephales notatus_ also occurred at all but three of these stations. #Percina copelandi# (Jordan): Stations C-4, C-5, C-6, C-8, G-1 (C-131, C-133, J&J). Channel darters were collected over bottoms of rubble or gravel, both in flowing streams and in isolated pools. Although _P. copelandi_ was found only in Big Caney River and at the lowermost station on Grouse Creek (G-1) in this survey, this species has been taken previously from Elk River (K. U. 3463 and K. U. 3197) and from Silver Creek. _Notropis camurus_ occurred everywhere that _H. copelandi_ was found. In several instances the two species were taken in the same seine-haul. #Etheostoma spectabile pulchellum# (Girard): Stations W-4, G-1, G-4, G-5, C-6, C-9, C-11, C-12, C-13, C-14, C-15, C-16, C-17, C-18, E-1, E-5. Evermann and Fordice as _Etheostoma coeruleum_ (C-131, C-132). The habitat preferences of the orangethroat darter seemed similar to those of _Campostoma anomalum_. There were sixteen stations at which both species were taken, seven where only _E. spectabile pulchellum_ was taken and six where only _C. anomalum_ was taken. The largest relative numbers of both species were found in the same small, clear upland tributaries of Big Caney River. On May 31, collections from riffles at station C-15 (upper Otter Creek) consisted almost entirely of these two species. On September 1 at this station the stream was intermittent, but even the tiniest pools abounded with young darters and stonerollers. Gravid females and males in breeding condition were taken in riffles in Cedar Creek on April 2. During June numerous young and adult orangethroat darters were taken in Cedar Creek, in partly decayed leaves which lined the banks. On June 15 in Otter Creek young darters were abundant in streamside detritus and in clear, shallow, rubble riffles. At station C-11 a few darters were taken on rubble riffles; however, large numbers were found inhabiting thick mats of _Potamogeton foliosus_ Raf., which grew in shallow water. Many darters (_Etheostoma spectabile pulchellum_ and _Percina phoxocephala_) were taken in September along gravelly banks at stations C-2 and C-3 by disturbing small rocks and leaf-litter along the shores. Young orangethroat darters seemed to seek out sheltered areas and in some cases were found in sluggish, even foul, water (Stations W-4, B-1 and G-12). Moore and Buck (1953:26) note that the orangethroat darter is able to thrive in Oklahoma in rather sluggish and even intermittent waters which reach quite high summer temperatures.
