Fishes of Massachusetts. 497 
of which are fourteen distinct, strongly serrated 
laminee. 
The Dorsal fin commences about the middle of 
the length of the fish, nearly two inches long, two 
lines high. Its anterior portion rounded, gradually . 
diminishing in height, as it approaches the tail. 
The Pectorals are somewhat rounded at the ex- 
tremities ; one inch two lines high ; three lines long. 
The Ventrals are narrow, five lines long ; attach- 
ed to the belly by a membrane extending from the 
inner ray. 
The Anal fin commences a short distance back of 
the dorsal ; of a similar form with that fin. 
_ The Caudal fin is nearly straight at its extremity ; 
three lines long, six lines high; the distance be- 
tween the extremities of the fin rays, is equal to 
their height. 
The fin rays are: D. 32; P. 24; V. 4; A. 30; 
C. 18. 
This species is smaller and lighter colored than. 
the “ Remora,” and differs in the number of its 
lamine in the disk. Without dwelling upon the 
less important distinctions, I conceive that the indi- 
vidual I have here described must be considered a 
new species.
