Indies and on the coast of Brazil, and the United States as far north 

 as Cape Cod. Its habits closely resemble those of the preceding spe- 

 cies. My largest specimen is nine inches long ; the fishermen claim that 

 the species attains the weight of five or six pounds, but they probably 

 confound this with some other species of the same family. 



Color. — Above, light slate: beneath, pearly white; snout and line over 

 the orbit blue. Second dorsal margined with black. Base of lateral 

 plates and tip of caudal light brown.

This universally-distributed species occasionally finds its way into 

 the hands of the Bermudian fishermen.

Not uncommon ; recorded also from Cuba aud South Carolina. A 

 specimen was taken near New York in October, 1875, and is now in the 

 National Museum. The Bouito is an excellent table-fish, and reaches 

 the length of two feet or more. 



The -Amber-fish," the " Guelly," or "Cavally " (Caballa ?), the " Slip- 

 pery Dick," and the " Skip-jack" of the fishermen probably belong to 

 this family ; but, as I secured no specimens, they cannot be identified. 

 Tbe "Skip-jack" is perhaps an Oligoplites, and the "Amber fish" is 

 doubtless a Seriola.

 Dolphin.

I observed a Dolphin, measuring five or six feet, playing about our 

 steamer in the Gulf Stream, about two hundred miles northwest of the 

 Bermudas. The Dolphin is well known to the fishermen.
