Mtxostoma ANISURA (Eaf.) Jordan. 

 (Not Moxostoma anisurus Agas.siz=Erimyzon oblongus (Mit.) Jordan.) 

 Catostomus anisurus Kirtland. 

 PtycJiostomus collapsus Cope. 



This species, described by Rafinesqac, 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 PtycJiostomus. Moxostoma becomes, therefore, a synonym of Pfychos- 

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

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

An insufficient description of some Carpiodcs "from a drawing by 'Mr. 

 lAudubon". iJafiuesque remaiks: "The C. tuherculatus of Le Sueur 

 jelongs also to this subgenus, having 8 abdominal rays, but its tail is 

 regularly bifid".
