upper anterior part of spinous dorsal black, the rest of the fin 

 white. 



The spotted cero is found from Cape God to Brazil, but is not 

 common northward; it is abundant in the West Indies. The 

 species grows to the length of 5 feet and the weight of 20 pounds; 

 it is a fish of the same good qualities as the Spanish mackerel 

 and is readily caught by trolling.

Body more slender and elongate than in the other species of 

 the genus, its greatest depth one sixth to one fifth of total 

 length without caudal; rather less compressed than in S. 

 regale; the least depth of caudal peduncle one half the length 

 of snout; head one fifth of total length without caudal; snout 

 acute, two fifths as long as head; maxjlla long, reaching beyond 

 hind margin of orbit; mandible a little longer than snout and 

 eye combined; eye small, one sixth of length of head, the inter- 

 orbital space convex; teeth triangular, much compressed, about 

 25 to 30 in each side of each jaw; gill rakers very short, eight 

 below the angle on first arch. The spinous dorsal is inserted 

 directly above the origin of the pectoral and slightly behind the 

 ventral; its base equals one half the distance from tip of snout 

 to origin of second dorsal; the second, and longest, spine is 

 three times as long as the last spine and two sevenths as long 

 as the head. The interspace between the two dorsals equals 

 diameter of eye. The second dorsal originates midway between 

 tip of snout and end of middle caudal rays; the base is as long 

 as the snout and eye combined and is about equal to anal base; 

 the longest ray is six times the length of last ray and equal to 

 snout; the upper margin of the fin is deeply concave; the fin is
