REVIEW OF RAPINESQUE ON AMERICAN FISHES. 27 



*36tli species, SlenderMinnir, MINNILUS DINEMUS, Minny emeraude. 

 (p. 46.) 



NoTOTROPis DINEMUS (Eaf.) Jordan. 



Alburnellus jaciilus Cope. 



The coloration and form are those of Alburnellus jaculus, with which 

 I have identified this description. 



t37th species, Spotted Minny, MINNILUS NOTATUS, Minny tache. (p. 47.) 



HyBOEHYNCHUS NOTATUS (Raf.) Ag. 



Hyhorhynclius notatus Agassiz. 

 Hyhorhynchus superciliosus Cope. 



Agassiz's identification of his HyhorJiynclms with this species is possi- 

 bly correct, although the description is very irrelevant. The common 

 Hyhorhynclius of the Ohio region has small but distinct barbels at the 

 angle of the mouth, and is therefore H. sitperciliosus of Cope. The latter 

 name is probably a synonym of H. notatus. 



1 33th species, Little-Mouthed Minny, MINNILUS MICROSTOMUS, Minny 

 microstome. (p. 47.) 



Hybopsis MICROSTOMUS (Raf.) Jordan. 



Sybopsis lonyiceps Cope. 

 Hybopsis microstomus (Raf.) Jordan. 

 This description agrees very closely with specimens sent me by W.M.
