REVIEW OF KAFINESQUE ON AMERICAN FISHES. 33

 ' 1st subgenus, MOXOSTOMA. (p. 54.) 

 Miixostoma Jor. 



(Not Moxostoma of Agassiz and authors = Erimyzon m.) 



t 53d species, Ohio Carp-Sucker, CATOSTOMUS ANISURUS, Catostome 

 anisure. (p. 54.) 



Myxostoma anisura (Eaf.) Jordan. 



(Not Moxostoma anisurus Agsissiz= Erimyzon oblongus (Mit.) Jordan.) 



Catostomus anisurus Kirtland. 

 Ptychostomus collapsus Cope. 



This species, described by Kafinesqae, and described and figured by 

 Dr. Kirtland, is said to possess a lateral line, and to have red fins. 

 Furthermore, it is known as " Carp", and reaches a length of 1 to 3 feet. 

 It is evidently not a Moxostoma as that genus is defined by Agassiz, but 

 a Ptyclwstomiis. Moxostoma becomes, therefore, a synonym of Ptychos- 

 tomus, and having priority must supersede it. In accordance with the 

 etymology of the word, I have changed the first vowel o to y.
