Habitat. — Mississippi Valley and Great Lake region, most 

 abundant in the central States. Not found east of the Allegheny 

 Mountains, nor in the Texan region. Frequenting sluggish 

 waters and bayous. 



The specimens examined by us are from Falls of Ohio ; Ohio 

 River, Southern Indiana ; Bean Blossom Creek, Monroe Co., In- 

 diana : Pipe Creek, Madison County, Indiana; Mecca, Parke 

 County, Indiana; Kankakee River at Riverside, Indiana, and 

 Hieksville, Defiance County, Ohio. 



This species lias the general coloration of E. reticulatus, with 

 its other characters, very close to those of E. americanus. From 

 the latter species it differs but slightly, but the greater length of 

 the snout, small as it is, seems to be very constant. 



The name Esox salmoneus, frequently applied to this species, 

 cannot be retained, as it was earlier given by Mitchill to Synodus 

 fifpteus. It is also probable that Rafinesque's original salmoneus 

 ie a mythical species, not identifiable with anything. In his copy 

 of the original drawing (in his MSS. note books i the insertion of 

 the dorsal is said to be represented as midway between the tip 

 of the snout and the base of the caudal.
