BULLETIN OF THE UNITED STATES FISH COMMISSION. 
31. Etheostoma aspro (Cope and Jordan). Black-sided darter. (E.) Not common; specimens small. 
32. Etheostoma ouachitee Jordan and Gilbert. (R.) Not a widely distributed species. It was 
also taken in Indiana in 1888, by Prof. Evermann, whose specimens are a little larger than 
those found in Rough Creek. Five of the largest of the latter measure as follows : Length, 
44 millimeters, 47, 46, 45, 43; head, 11, 12, 12, 11, 11; depth, 6, 6£, 6|, 6, 6i; lateral line, 51, 
55, 52,52,53; dorsal, X-12, X-12, XI-12, X-12, X-12; anal, 11-10, 11-10, 11-10, 11-10, 11-10. 
33. Etheostoma phoxocephalum Nelson. (R, P.) Common; only young specimens taken. 
34. Etheostoma cceruleum Storer. Rainbow darter. (P.) Rare,. Three small specimens taken. 
35. Aplodinotus grunniens Rafinesque. White perch; fresli-water drum. Common in both streams. 
UPPER GREEN RIVER. 
The Upper Green River and its tributaries flow, for the most part, over a Sub- 
carboniferous area, cutting down to the Devonian in places. The stream is less deep 
here and has a good current; the banks are not so precipitous, and the bottom is 
covered with sand and gravel. At intervals the sand is piled up in large banks or 
bars, which form islands, or jut out into the river, making excellent places for collect- 
ing. Two regions were visited: (1) The Big Barren River and two of its tributaries, 
Drake Creek and Beaver Creek, in the neighborhood of Bowling Green, Warren 
County, where the surface rocks are chiefly Upper Subcar boniferous. (2) The Upper 
Green River proper, and one of its tributaries, Pitman Creek, on which the Lower 
Subcarboniferous rocks crop out. 
BIG BARREN RIVER. 
1. Big Barren River , at Bowling Green : The collecting station was tliree-fourths 
of a mile northeast of the city; water temperature, 80° F. The Big Barren River rises 
in Monroe County, and flows in a northwesterly direction for 75 or 80 miles to the 
Green River, which it joins at the northwest corner of Warren County. The stream 
at Bowling Green, about 20 miles from its mouth, is from 100 to 125 feet wide, clear 
and deep, and with considerable current. Most of the specimens were taken on or near 
a large shoal or sandbank above the water works. Here the bottom was of coarse 
gravel and sand, with a rock bottom which in the deeper places was covered with 
mud. There were no algae or other water plants in the stream, but crayfishes, clams 
( JJnio), and turtles ( Aspidonectes ) were common. The stream is an excellent one for 
fish, the water being clear and pure; the specimens taken were flue, being very active 
and with the colors bright and fresh. It is well stocked with good food-fishes, and 
contains an abundance of minnows and darters. The surrounding country is rolling 
and has a limestone soil, producing good crops of grain and fruit. Forest trees of 
ash, elm, sycamore, and birch were noticed on the banks of the river. 
2. Drake Creek: Collections were made, August 2, 8 miles southeast of Bowling 
Green, just below the “ Shaker Mill,” and about 5 miles from the point where this creek 
flows into Big Barren River. The temperature of the water was 74° F. At the place 
visited the stream is about 15 yards wide, the bottom composed of loose, flat stones on 
the rapids, with stretches of mud bottom between them.
