Common in cold waters; those from the South Fork paler and more spotted than 
usual ; those from Hot Springs very dark. 
N.— ST. JOSEPH’S RIVER. 
St. Joseph’s River has its rise in southwestern Michigan. It flows southward 
into northern Indiana. At South Bend it makes an abrupt turn to the northward, 
flowing back to Michigan, and ultimately into Lake Michigan. Like most of the 
Michigan streams, its waters are clear and cold, and it is fed largely by springs. Col- 
lections were made at a point between Mishawaka and South Bend, about a mile 
below the former place. September 17 and 18; temperature 60°; air 55°. The 
stream is here large, flowing over a bottom of coarse gravel, with sand in the deeper 
and more quiet portions. The rocks are well covered with algae and other water- 
plants, Chara being abundant in places. The water was too cold for successful work 
and the species obtained are those characteristic of the Upper Wabash. This shows 
that the low and often swampy water-sheds separating the Wabash, Kankakee, and 
St. Joseph’s are of little consequence as a barrier to the distribution of fishes. 
1. Catostomus teres (Mitchill), 
Scarce, 
2. Catostomus nigricans (Le Sueur). 
Scarce. 
3. Moxostoma aureolum (Le Sueur). 
Scarce. Young specimens; the head much shorter, the mouth smaller and lower, 
than in ilf. duquesnei.

Common. 
5. Pimephales notatus (Eafinesque). 
Common. 
6. Notropis microstomus (Eafinesque). (Rybopsis stramineus Cope).

is a color mark characteristic of this species.
