G8 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY III. 



01. CERATiCHTnYS wiNCHELLi {Givard) Jordan, 



{Ceratichthys hyalinus Cope.) 



Everywhere abundant in Tennessee River. This is probably Hyhoims 

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

 will be neo^ssary to substitute the specific name gracilis for unncheUi. 



62. Ceratichthys biguttatus {Kirtland) Girar-d. . 



Everywhere very abundant. 



Genus SEMOTILUS Rajinesque. 



G3. Semotilus corporalts {31it) Putn. 



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

 ain-streams. 



CATOSTOMID^. 



Genus QUASSILABIA Jordan d Brayton. 



64. Quassilabia lacera Jordan & Brayton. 



Lagochila lacera Jordan & Brayton (1877), Proc. Ac. Nat. Sc. Phila. 



Two specimens of this singular fish 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 food. It is usually known as the ." Hare-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 

 fishermen under the name of "May Sucker". 



Genus MYXOSTOMA Bafinesque. 

 65. Myxostoma velatum (Cope) J or. 



(Ptychostomus collapsus Cope.) 



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

 amauga. 



66. Myxostoma macrolepidotum duquesnii (Le S.) Jor. 



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