124 FISHES OF MASSACHUSETTS. 



Nostrils double, posterior lower and larger ; the vpper jmo pro- 

 jects beyond the lower ; in the lower jaw is a single row of 

 teeth ; those in the back part of the jaw, large, and incurved ; 

 those in the fore part of the jaw much smaller ; in the upper 

 jaw a row of large teeth in the back part, with a row of minute 

 teeth back of them ; approaching the middle of the jaw, a triple 

 row is observed ; at the middle of the jaw, four distinct rows 

 are seen ; the front row uniformly large, those behind very small. 

 A single barbule about an inch long at the chin. The lateral 

 line commencing above the operculum, makes a very gradual 

 slope upwards, and as gradual a curve downwards, until oppo- 

 site the anterior third of the second dorsal fin it commences a 

 straight course which is continued to the caudal fin ; this line 

 is lighter colored in its whole extent than the body, it is wider 

 and more conspicuous after assuming a straight course. 



The first Dorsal arises just back of the pectorals ; the se- 

 cond Dorsal is much longer than the first ; the third is slightly 

 longer than the first. All the dorsals are of a bluish color, 

 spotted like the body. 



The Pectorals are round ; their length is equal to half their 

 height. 



The Ventrals are situated in front of the pectorals, of the 

 color of the abdomen ; the two outer rays of the ventral fins 

 are free, the second ray is the longest. 



The first Anal fin is shorter than the second dorsal ; the se- 

 cond anal, much shorter ; both anals the same color as the ab- 

 domen. 



The depth of the Caudal fin at the extremities, to its length, 

 as 2 to 1 ; spotted like the rest of the body. 



The fin rays are : B. 7 ; D. 15-22-19 ; P. 19 ; V. 6 ; A. 22- 

 19 ; C. 40.
