Head 3f to 3f ; depth 4 to 4+; D. iii, 7, i; A. iii, 6, i; scales 32 to 

 35 + 2; 5 or 6 scales above 1. 1. ; 3 or 4 scales below 1. 1. ; 13 or 14 

 predorsal scales; snout 3f to 3| in head; eye 3$ to 3|; maxillary 

 2f to 3; interorbital 3 to 3^; teeth 2, 4-4, 2; length 2± to 2A inches. 

 Two examples from Blue River, Indiana. 



Notropis illeoebrosus (Girard). PI. XVI, fig. 11. 



Alburnops illecebrosus Girard, Proc. Acad. Nat. Sci. Phila., 1S56, p. 194. 

 Arkansas River, near Fort Smith. 



Cotype of A. illecebrosus. The fish called N. illecebrosus by Jordan 

 and Evermann 2 , to which is added "description here drawn up from 

 the types" is confusing, as they give: A. S; scales 7-35: 11 pre- 

 dorsal scales; teeth 1.4-4,1; all of which is not in agreement with 

 my example, as may be seen by Meek's notes. This latter may be 

 considered unquestionably the type of the present species, as Meek 

 is the first to restrict it , therefore, while specimens of A . sh umardi may be 

 identical as suggested by Jordan and Gilbert, 3 it is not possible to so 

 determine, as Jordan had already stated that the types of A. shumardi 

 were lost. However, if the two are ever demonstrated to be identical, 

 the name shumardi has precedence.
