Numerous specimens of this species were examined from 

 Lake Superior (off Isle Royal, Lizard Islands, and Sault Ste. 

 Marie), and one from Lake Michigan (ofif Ludington, Mich- 

 igan). Cottus franklinii is known only from rather deep water 

 in Lakes Superior and Michigan. The three nominal species, 

 franklinii, hoyi, and kuuilicni, the latter two described from 

 Lake ^Michigan, seem to be inseparable, comprising a form 

 but slightly differentiated from Cottus gracilis. 



One specimen in the series at hand from Lake Superior has 

 three soft pelvic rays on one side, four on the other.
