 length. D. 13. or more rarely 12 or 14 ; A. 7 ; scales about 45. Color oliva-

Until very recent 3< T ears this has been recorded as two species, 

 the short-headed, small-mouthed form as M. aureolum, and the 

 more ordinar}^ form as M. macrolepidotum duquesnii (Le Sueur). 

 This matter is cleared up by Jordan and Evermann (Bull. 47, 

 U. S. Natl. Mus.). It is very probable that some collectors have 

 confused the short-headed form with M. breviceps (Cope), as I 

 can find no record of M. breviceps for Ohio in any paper preceding 

 Bull. 47, U. S. Natl. Mus., in which it is recorded as abundant 

 in some portions of the state. However, as I have no direct evi- 

 dence of any such error, I include all records for M. aureolum 

 and M. macrolepidotum duquesnii under M. aureolum. Ohio
