HISTORY OF THE FISHES OF MASSACHUSETTS. 81 



Just aoterior to the origin of the anal fin are two very minute naked spines, the ante- 

 rior of which is the smaller. 



The anal fin is similar in form to the second dorsal, and terminates on a plane with it* 



The caudal fin is very deeply forked ; its rays are articulated, and its two extremities 

 terminate in sharp points. 



Length, about ten inches. 



The fin rays are as follows : — D. 1 -7 --SS. P. 20, V, 6. A. 2-20. C. 15|. 



Remarks, I have seen but two specimens of this fish. Both of these were caught in 

 the harbor of Wellfleet, one in August, 1844, and the other in November, 1849. De- 

 kay speaks of it as not being uncommon in Long Island Sound.

The tail unarmed ; the little fins or the detached spines before the anal, as in Seriola. 

 The first dorsal fragile and low, the second and the anal covered with small scales ; 

 but the principal character consists in a row of separated, pointed, and cutting teeth in 

 each jaw ; behind the upper ones is a row of smaller teeth, and there are some fine as 

 velvet on the vomer, palate, and tongue. The operculum terminates in two points, and 

 there are seven branchiostegous rays.
