 short, stiff spines with a membrane behind each, the first of 

 these spines two thirds as long as the eye; the longest anal ray 

 is one half as long as the head and three times as long as the 

 last ray; the fin is followed by a single two-rayed finlet which i» 

 three fourths as long as the eye. The ventral origin is equally 

 distant from tip of snout and anal origin; the fin reaches to 

 below the sixth spine of the dorsal, its length one half the 

 length of head. The pectoral reaches to below the end of the 

 spinous dorsal, its length three fourths of length of head. Head

The dotted scad, or round robin, is a very common fish at the 

 Bermudas and in the West Indies. On the east coast it is found 

 from Cape Cod to Brazil, but only young or half grown speci- 

 mens are taken on Long Island and around Cape Cod. The 

 species grows to the length of 1 foot. In the Bermudas it is an 

 important food fish and furnishes infinite sport for the small 

 anglers. 



Dr Mitchill illustrates it in fig. 5, pi. 5, of his Fishes of New 

 York, and names it the hippos mackerel. In Dr De Kay's New 

 York Fauna it is the spotted caranx. It is taken not uncom- 

 monly at Woods Hole Mass. The species appears to be rare in 

 New York waters, as it was known to De Kay only from the 

 descriptions of Mitchill and Cuvier. The fish has not been recog- 

 nized in Gravesend bay, but it is abundant in August at South, 

 ampton L. I. and has been taken at Fire Island in October dur- 

 ing the fall migration.
