12 FISHES OF MASSACHUSETTS. 



ored margin. Just above this spot, arises the lateral line, which 

 assumes the curve of the back, and is lost at the base of the 

 tail. The back curves very gradually as far as the posterior 

 extremity of the dorsal fin, then abruptly gives place to the 

 fleshy portion of the tail. All the fins more or less colored 

 with black. Length of the pectoral fins nearly two inches. 

 Anus large, corrugated — two lines anterior to the anal fin. 



The fin rays are as follows : D. 10-12 ; P. 13 ; V. 1-5 ; A. 

 3-10; C. 17.

 species of Pomotis inhabits our waters.

This species which is very well described, and tolerably figur-

 the vicinity of Holmes Hole, while fishing for other species, 

 but is not used. 



A beautiful specimen received from Dr. Yale enables me to 

 offer the following description :
