Two specimens of this singular tish were taken in the Chickamauga 

 Eiver at Ringgold and one specimen in Elk River at Estill Springs. In 

 the Chickamauga, we were told that it is quite common, and that it is 

 much valued for tbod. It is usually known as the " Ilare-lip " or " Split- 

 mouth Sucker". We have lately received a fine specimen taken in the 

 Scioto River, Ohio, by Mr. J. H. Klippart, where it is well known to the 

 fishermt'ii under the name of " ]\Iay Sucker".
