ART. 33. NOTES ON FISHES OF HAWAII — E. K. JORDAN 15 



CARANX MELAMPYGUS Cuvier and Valenciennes, Ulua. 



This species is the common Uhia, one of the most valued food fishes 

 throughout the South Seas. 



It may be distinguished from near relatives by its soft dorsal of 

 25 soft rays, the anal of 19, and by the completely scaled breast, a 

 character shown also by Caranx stellatus, the common and almost 

 equally valued Omilu. In C<i}ranx melampygus the pectorals are 

 bright clear yellow in life, the ventrals white, the anal and dorsal 

 pale at base, their produced tips black, the distal portion of the 

 anal especially so, and there are never any black spots or blotches on 

 the body. The longest dorsal ray is a little more than half base of 

 the soft fin, and about the same in depth of body. According to 

 Doctor Wakiya^^ Garanx hixanitJio'pterus Eiippell, from Southern 

 Japan differs from Garanx meXampyg'us in having the lobe of the 

 soft dorsal 2i/6 in the base of the fin. Garanx hixanthopterus^ as 

 thus defined, has not been found in Hawaii. This species was 

 wrongly called Go/ranx forsteH in Jordan and Evermann's Fishes of 

 Hawaii (p. 191). 



CARANX STELLATUS Quoy and Gaimard. 



{Caranx melampyyua Giinther and .Jordan and Evermann, not of Cuvier and 

 Valenciennes. ) 



The Omilu, one of the largest members of this genus and a valued 

 food-fish, is closely related to the Ulua. It may be loiown at all 

 ages by the dusky ventral fins and the presence of small scattered 

 black spots over the body. The young are silvery, like the Ulua, but 

 with age the color becomes dusky, and the irregular black spots more 

 numerous and larger. In the young, the pectorals are pale, with a 

 median yellow stripe, becoming dusky with age. The dorsal, anal, 

 and ventrals are entirely black in the adult. Dorsal lobe about as 

 in the Ulua, 1^ in head in adult, ll^ in young. 



CARANX MARGINATUS GUI. 



This species, not rare at Honolulu, much resembles Garanx me- 

 la?7ipygios, but the soft rays of the anal number 16 instead of 19, 

 and the dorsal rays are 22. The soft dorsal is throughout broadly 

 edged with black, the anal pale, with a row of darker spots at base, 

 along the tips of the interhaemals ; caudal edged with dark; ven- 

 trals and pectorals pale; a black spot in the axil; a small black 

 opercular spot. 



In the account of Garanx marginatus of Jordan and Evermann,^^ 

 from Panama, the soft rays of the dorsal are given as 19, the anal 

 15. The usual numbers, as recorded by Gilbert and Starks, run 

 higher (D. 20 or 21; anal 16 or 17), agreeing in this regard with
