91. Caranx crysos (Mitchill). “ Cojinuda” ; Hard-tail ; Runner; Jurel; Yellow Mackerel; Crevalle. 
(Plate 9.) 
Head 3.5; depth 3.2; eye 5.6; snout 3; maxillary 2.4; mandible 2.1; interorbital 3; preorbital 11; 
D. vm-i, 24; A. ii-i, 20; pectoral 0.8; ventral 2.3; caudal 0.95; about 45 scutes. 
Body elongate, slightly elevated, not greatly compressed; maxillary reaching front of pupil or 
middle of eye; teeth in jaws conical and sharp, not very close-set, in one series in lower jaw, in two 
in upper, inner series of smaller teeth; no canines; lateral line more strongly arched anteriorly than 
in C. ruber or C. bartliolomxi, arch rather more than half straight part; pectoral long and falcate, reaching 
anal or slightly beyond; anterior rays of soft dorsal and anal elevated and falcate. A distinct black 
blotch on opercle. 
This species is found from Cape Cod to Brazil, is generally abundant, and is common farther to 
the north than any other of the species of Caranx. It is an important and well-known food-fish, fairly 
common. In Porto Rico only two specimens were collected, one 10.5 inches long from San Antonio 
Bridge, and one 17.5 inches long, which was taken on the hook at Isabel Segunda, displaying good 
game qualities. This is one of the best game-fishes of Porto Rico and can be taken by either still- 
fishing or trolling.
