Sub-class Teleostei. Cottoid^. 



Acanthocottus Groenlandicus, Girard. 

 Greenland Sculpin. 



This is the handsomest of the sculpin beauties, but is not so 

 abundant as last described species. It can be distinguished from 

 it by the different markings of its colors, and by a " quadrangular 

 area in the head, bounded by four tubercles ; circular white spots 

 upon the abdomen ; dark brown color of the body, with large clay- 

 colored blotches on the top of the head and upon the gill covers, 

 with a few smaller ones on the "back and sides ; and small circular 

 spots on the sides toward the abdomen." 



It may also be distinguished by the feel of the sides of the body, 

 both above and below the lateral line, which are " roughened by 

 granulated tubercles, which seem like spines when the finger is 

 drawn over them."

Richardson and Bonaparte have separated the Triglidge family 

 to which this genus formerly belonged, into several new ones — 

 placing the above into the newly family Cottoidse and sub-family 

 Cottinae. 



Genus Hemitripterus, Guv. 



Gen. Char. The head depre.ssed ; two dorsals ; no regular scales on the skin, 

 but teeth in the palatines ; head is bristly and spinous, and has several cutaneous 

 appendages. The first dorsal is deeply emarginate, a circumstance which has led 

 some authors to believe there were three dorsal fins. — Storer. 



Hemitripterus Acadianus, Storer. 

 Deep water Sculpin. 

 One of the most elegantly colored though at the same time un- 

 couth of the sculpin tribe, is the "Deep-water Sculpin," as it is 

 called ; called also by fishermen Sea Rover, which though not ex- 

 actly coming under the same genus is nevertheless closely allied 

 to it in form and habits. It is taken often times when fishing for
