Jordan and Evermann. — Fishes of North America. 191 



silvery below ; dorsal flu dusky. (Cope.) Missouri River at St. Joseph. 

 Type about 4 inches long ; a doubtful species said to be allied to Moxos- 

 toma c()llap>:Hm, but the dorsal has fewer rays. It is possible that this is 

 a valid species between (inistiruin and pidicnse, but no species with the 

 yy-shaped lips of anisurum have been found in the Missouri River by other 

 collectors. It will not unlikely prove to be a young red horse or possibly 

 the young of Mmytrema melanops. (.bucco, thick cheeks, from the interoper- 

 cular width of the head.)
