 superficially similar M. duquesnei, which

Hybopsis aestivalis hyostoma (Gilbert). 

 Ohio speckled chub. — Reported from the 

 Middle Fork on the Champaign-Ford 

 county line as Hybopsis hyostomus by 

 Large (1903:19). The locality, which is 

 far removed from other records of the 

 species, was either ignored or overlooked 

 by Forbes .k Richardson and Thompson 

 & Hunt; inasmuch as Large's specimen is 

 not extant for reidentification and addi- 

 tional specimens have never been taken, 

 the record is open to doubt.

 nesque). Northern bigeve chub. — FR 6

 barrass, Salt Fork, Middle Fork).

 Fork, Sangamon), LS 70 (Kaskaskia, Salt 

 Fork. Middle Fork, Sangamon).

 chub. — A specimen from the Middle Fork 

 reported by Forbes & Richardson. A sec- 

 ond specimen, an individual 4.5 inches
