COTTID.E. XGV. 251 



attached to a stout bone ; grayish silvery, dusky above ; 

 scales rather large and irregularly placed, punctate with 

 black; D. IX I, 30; A. II, 7; lat. 1. 54. Great Lakes, 

 Mississippi Valley, etc., abundant. (Corvina oscula and 

 C. grisea, of authors.) Three other species of this genus 

 have been' described but their validity is extremely 

 doubtful. Southward this species is considerably valued 

 as food, but in the Great Lakes its flesh is ill-scented 

 and worthless. The large " ear-bones " of this species 

 are marked with a rude "Z," and are highly valued by 

 Wisconsin boys as " lucky stones."

 LAKE DHU.NL. Head and shoulders much elevated; pro- 

 file very steep; eye moderate; mouth rather large; the

 IX I, >'.); A.I,;; lat. 1.54. Lake Huron. (I retain 

 this genus with much doubt. No specimens except the 

 original type are known, and this may have been merely 

 a monstrosity of the ordinary Haploidonotus
