120 BULLETIN OP THE UNITED STATES FISH COMMISSION. 
at Arlington, Mo., and at a point 5 miles higher. Here it is a clear stream flowing for 
the most part over a gravelly and sandy bottom. The river is about 125 yards wide 
and at times of low water easily forded. Vegetation in the river was scarce, and but 
few fishes were taken in each haul of the seine. The temperature was 80° Fah. 
Little Piney River is an eastern tributary of the Gasconade. It is a clear stream of 
water flowing with a considerable current. The bottom is sandy and gravelly with 
scarcely any mud except near its mouth, which is at Arlington. In times of low water 
the stream between Arlington and ilewburg, Mo., seldom exceeds 20 or 30 feet in width. 
The stream is largely fed by springs, and is said always to contain considerable run- 
ning water. Our seining was done at Newburg and at Arlington, Mo. The supply of 
smaller fishes was quite large. Larger fishes are taken in small numbers in the larger 
holes. The temperature of Little Piney at Newburg was 76°; at Arlington, near its 
mouth, 79°. 
The Osage Fork of the Oasconade. — This stream was visited about 6 miles south- 
east of Marshfield, Mo. It is a sluggish stream, some 50 feet wide in the broadest 
places. In the deeper places the bottom was muddy, elsewhere somewhat rocky. The 
water was not clear at the time of our visit, while the waters of the Niangua visited the 
previous day were very clear. The temperature was 97° Fah. 
The LogTc Fork of the Gasconade. — This stream was examined at Mansfield, Mo. It 
is nearly twice the size of the Osage Fork, its waters clearer, and the bottom with 
much less mud. ( itherwise it is much like the Osage Fork. This stream is seined a 
great deal by the people living on its banks near Mansfield. Large cat fish are said 
to be taken frequently. ISlot many fish were obtained by us. The temperature was 
78° Fah. 
Big Piney River was visited near Cabool, Mo. It is here a small stream, with a 
rather sluggish current and a stony bottom. Near Cabool the stream widens until it 
is about 60 to 100 feet wide and from 2 to 10 feet deep. Fish are apparently searce 
in this stream. The scarcity is in some measure due to the presence of gristmills and 
sawmills, which discharge refuse substances into the stream, and to the use of dyna- 
mite. It is reported that dynamite is frequently used in this region. The temperature 
was 74° Fah. 
Jones’’ Creek is a small stream near Dixon, Mo. It is little more than a small 
brook, seldom exceeding 30 feet in width. It has a rocky and gravelly bottom, with 
occasional stretches of sand. Temperature 76° Fah. 
1. Noturus e^filis Nelson. 
Dorsal and caudal fins tipped with black. Common in Jones’ Creek; a few speci- 
mens from Little Piney. 
2. Leptops olivaris (Rafinesque). 
A few specimens were seen in the market at Newburg, Mo. They were reported 
to be from the Gasconade. 
3. Ameiurus melas (Rafinesque). 
Two specimens from the Big Piney. Color, silvery ; the distal half of each anal 
ray black, the rest of each ray the color of the body. 
4. Ameiurus nebulosus (Le Sueur). 
One specimen from the Osage Fork of the Gasconade. Anal rays, 22. 
5. Ictalurus punctatus (Rafinesque). 
A few specimens seen in the Newburg market, from the Gasconade.
