Jolomieu, Lacepede), channel-cat (Ictalurus punctatus, Rafinesque), 

 common red-horse, or mullet ( Moxostoma macrolepidotum, Le Seuer), 

 and the pickerel ( Esox vermiculatus, Le Seuer) — locally called "moun- 

 tain-trout." Each of these forms is very abundant, the bass and pick- 

 erel apparently exceeding the remaining two in numbers. 



To Dr. D. S. Jordan, of Indiana University, my thanks are espe- 

 cially due for his courtesy in examining and identifying the major por- 

 tion of these species, and in the verification of others. Examples of 

 most of the species, from many of the localities named, may be seen 

 in the museum of the Indiana University, Bloomington, Indiana, and 

 in the United States National Museum, Washington. 



REGISTER OF SPECIES. 



i. Ictalurus punctatus, Rafinesque. (134.)* 



Piney River, Texas County. Not seen in the streams of the south- 

 ern slope, though it doubtless occurs in them. 



2. Catostomus teres, Mitchell. (170.) 



Jack's Fork, Shannon County; Tom's Creek, tributary to West Fork 

 of the Black River, Reynolds County. [See Jordan's Catalogue for 

 notes on the relation of this form to C. commersoni, and the use of the 

 name teres.~\ The specimens taken were none of them over one-third 

 grown. 



3. Hypertelium nigricans, Le Seuer. (171.) 



Tom's Creek, Reynolds County; Meramec River, Dent County. 

 Only young specimens taken. 



4. Moxostoma macrolepidotum, Le Seuer. (185.) 



West Fork Black River, Reynolds County; Jack's Fork, Shannon 

 County; Meramec River, Dent County; Big Creek and Piney River, 

 Texas County. This attractive sucker is very abundant throughout 

 the interior of the continent. Very fine and large examples have been 

 taken in the Des Moines and Raccoon Rivers, in central Iowa. It 

 appears to be equally at home in the sluggish streams, characteristic of 

 prairie regions, and in the clear and rapid streams of the mountains. 

 It is largely used as a food-fish throughout the Mississippi Valley. 



5. Campostoma anomalum, Rafinesque. (196.) 



This most curious fish is exceedingly abundant in every stream in 

 which collections were made. Unlike certain other fishes of wide dis-

of the Fishes known to Inhabit the Waters of North America, North of the Tropic of Cancer,"
