NOTE ON CARANX RUBER AND CARANX BARTHOLOM^I. 

 By DAVID 8. JORDAIV au«l CHARLiE^ H. OIL,BERT. 



In our Eeview of the American Carauginfe (Proc. U. S. Nat. Mus. 

 1883, 188-207), we have provisionally referred (p. 198) the names Car- 

 anx bartholomm C. & V., Caranx cihi Poey, Caranx iridinvs Poey, and 

 Caranx heani Jordan, to the synonymy of Caranx ruber {Tj\oc\i) = Caranx 

 blochi C. & V. An examination of many specimens collected by Profes- 

 sor Jordan of the " Cibi amariUo^^ {Caranx cibi Poey) and the " Cibi car- 

 bonero^^ {Caranx iridhms Poey) of the Havana markets shows that the 

 two species are really distinct, although closely related. The " Cibi car- 

 bonero^^ is more elongate than the " Cibi amarillo.^' the depth in speci- 

 mens a foot long, 3^ in length ; the head smaller, 3f in length, the straight 

 portion of the lateral line longer, considerably longer than curved part, 

 2^ in body. In color it is bluish olive, silvery below, scarcely tinged 

 with yellow in life ; a vaguely defined horizontal stripe of clear blue just 

 below the dorsal fin. Dorsal yellowish gray; other fins dusky olive; a 

 distinct blackish bar extending the length of the lower lobe of the caudal. 



In the " Cibi amariUo''' (called Yellow Jack at Key West) the body is 

 rather deep, the depth in specimens a foot long, 24 in length ; the head 

 3-i- ; the straight part of the lateral line scarcely as long as curved part, 

 24 iu head. The color is bluish silvery in life, everywhere strongly 

 washed with golden ; the young sometimes with round golden spots ; 

 blue stripe along side of back very faint or obsolete ; yellow brightest 

 on back, on iris, and along base of anal; fins all pale yellow, the color 

 most intense on anal and ventrals ; no blackish stripe on lower lobe of 

 caudal. 



In numbers of fin rays and scutes, in dentition, and in form of the 

 fins, the two agree very closely. The soft dorsal and anal, although 

 very low anteriorly, are in both slightly falcate. Our analysis of spe- 

 cies on page 194 is therefore erroneous as regards these species. 



The following is an outline of the synonymy of the two species, which 

 may be amplified by reference to page 198 :
