COTTLD^E. XCV. 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 "_L," and are highly valued by 

 Wisconsin boys as "lucky stones." 



2. EUTYCHELITHUS, Jordan. LAKE HURON DRUMS. 



1. . richardsonii, (C. & V.) Jordan. MALASHEGANAY. 

 LAKE DRUM. Head and shoulders much elevated; pro- 

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

 lower jaw rather projecting; head nearly one-third of 

 length; depth about one-half; anal spine stout (single?), 

 one-third shorter than the soft rays; pectorals pointed, 

 much longer than the ventrals; opercular bones all finely 

 serrated; greenish with dark bands on the back; D. 

 IX I, 29; A. I, 7; 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 grunniens.) 



FAMILY XCV. COTTID^E. 



(The Sculpins.) 



Fishes with the cheeks mailed (i. e., the suborbital bone 

 extending backward over the cheeks, articulating with 

 the preopercle) ; head broad, usually not externally bony, 

 but always more or less spinous; eyes high up, near 

 together; body sometimes scaly, or with a series of bony 

 plates, naked in all our species; dorsals usually two,
