68 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY III. 



61. CERATICHTIIYS WINCHELLI (Girard) Jordan. 



(Ceratichthys hyalinus Cope.) 



Everywhere abundant in Tennessee River. This is probably Hybopsis 

 gracilis Ag., the original type of the genus Hybopsis. In that case, it 

 will be necessary to substitute the specific name gracilis for winclidlL 



62. CERATICHTHYS BIGUTTATUS (Kirtland) Girard. 

 Everywhere very abundant. 



Genus SEMOTILUS Eafinesque. 



63. SEMOTILUS CORPORALIS (Mit.) Putn. 



Tributaries of the Clinch and French Broad ; chiefly in small mount- 

 ain-streams. 



CATOSTOMIDJE. 



Genus QUASSILABIA Jordan & Brayton. 

 64. QUASSILABIA LACERA Jordan & Brayton. 



Lagochila laccra JORDAN & BRAYTON (1877), Proc. Ac. Nat. So. Phila. 



Two specimens of this singular fish were taken in the Chickamauga 

 Eiver at Einggold and one specimen in Elk Eiver at Estill Springs. A 

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

 much valued for food. It is usually known as the " Hare-lip " or " Split- 

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

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

 fishermen under the name of "May Sucker". 



Genus MYXOSTOMA Eafinesque. 

 65. MYXOSTOMA VELATUM (Cope) Jor. 



(Ptychostomus collapsm Cope.) 



Obtained by Professor Cope in Clinch Eiver, and by us in the Chick- 

 amauga. 



66. MYXOSTOMA MACROLEPIDOTUM DUQUESNII (Le S.) Jor. 



From the Holston, Clinch, French Broad, and Chickarnauga. Proba-
