JORDAN AND JORDAN: FISHES OF HAWAII. 39. 



Caranx Lacepede. 

 (THcropterus Rafinesquc; Carangu-s Girard.) 

 Under this name we include the C'arangoid fishes with the teeth in the jaws 

 not in vilhform bands, teeth on vomer and palatines; back more or less elevated, 

 but not excessively so, and none of the dorsal spines filamentous. The group has 

 been further subdivided by authors, but not very successfully. The proper logo- 

 type of Camnx is yet to be determined. 



244. Caranx ignobilis (Forskal). Pauuu. (J. & E., p. 188.) 

 Carangus hippoides Jenkins. 



This common and widely diffused species corresponds to Caranx hippos of the 

 Atlantic. It is known from related species by the presence of a small patch of 

 scales on the otherwise naked breast. 



245. Caranx rhabdotus (Jenkins). (J. & E., p. 193.) 

 Carangus rhabdotus Jenkins. 



A small deep-bodied species, marked by dark cross-bars. Anal fin yellow. 

 It ascends into fresh waters. It has hitherto, perhaps correctly, been identified as 

 Caranx sexfasciatus Quoy and Gaimard. 



246. Caranx melampygus Guvier and Valenciennes. Ulua. (J. & E., p. 191.) 

 Caranx bixanthopterus Riippell. 



Caranx J orsteri Jordan and Evermann, nan Guvier and Valenciennes. 



This species, distinguished from C. ignobilis by the scaly breast, is one of the 

 most abundant and valued food-fishes of Hawaii. There, as elsewhere throughout 

 the South Seas, it is known as Ulna. It corresponds to Caranx latus of the Atlantic. 

 Pectoral fin bright yellow in life, anal dusky. It has been wrongly identified with 

 C.f orsteri G. & V., a species with fewer fin-rays. Wakiya regards C. bixanthop- 

 terus as the same species. C . heberi has fewer fin-rays. 



In the original description of this species it is said: Ge poisson parait d'ailleurs 

 avoir ete argente, et teint vers le dos d'un plombe verdatre; Les deux pointes de 

 ses nageoires sont noiratres, mais celle de I'anale plus que Tautrc." 



All this applies perfectly to the Ulua, but the dusky "Omilu" with the sides 

 sprinkled with small black points, could never have been described in this way. 

 Both the Ulua and the Omilu ha\e dorsal rays in increased number — D. I. 23 or 

 24; A. I. 19 or 20. The Ulua is known in life by its dusky anal (hence melam- 

 pygus) and its bright yellow pectoral. 

 247. Caranx marginatus Gill. (J. & E., p. 191.) 



This species is very close to Caranx f orsteri, but apparently distinct.
