CATOSTOMIDJ3, CIX. 319 



proposed for E. mdanops. Great Lakes, Ohio Valley 

 and South, abundant; one of our handsomest suckers, 

 strangely overlooked by recent writers. This and the 

 next, unlike most of our suckers, are very hardy in the 

 Aquarium.

 SUCKER. Head 4 to 4 in length; depth 2f, in adult; 

 eye 5 in head; scales crowded, deeper than long; no trace 

 of lateral line; dusky above, brassy on sides and below; 

 very variable; young much less compressed, with black 

 bands or bars, and pale lateral and vertebral streaks;
