ART. 33. NOTES ON FISHES OF HAWAII E. K. JORDAN 13 



erate, 21/2 in head. Pectoral long, reaching second dorsal finlet- 

 preorbital narrower than in Neothunmis 7nacropterus. Finlets 9/8. 

 This fish is apparently identical with the Shibi or Mebachi (wasp- 

 eye) of Japan. It is common in the markets both of Hawaii and 

 Japan. These large fishes are rarely obtained by native Hawaiian 

 fishermen, but are secured in great numbers by the adventurous 

 Japanese, who go far out to sea, and who now monopolize the island 

 fishing. 



Genus NEOTHUNNUS Kishinauye 



NEOTHUNNUS MACROPTERUS (Schlegel). Ahi. 



The yellow finned Albacore is abundant in deep water about 

 Hawaii ; common also in Southern Japan and about the Santa Bar- 

 bara Islands of California. 



This species is known at once by its bright lemon yellow finlets 

 colored alike above and below, each one anteriorly edged with a 

 narrow line of black ; pectoral edged with black, a little longer than 

 head and reaching almost to the second anal finlet; dorsal very 

 high, 1 j% in head, the lobes of dorsal and anal dull yellow, edged 

 with black; finlets 8/9. Preorbital broad. No crosslines of spots 

 on body; some elongate spots of dull silvery sometimes present. 



Genus KATSUWONUS Kishinouye 



KASUWONUS PELAMYS (Linnaeus), Aku. 



This species, the Aku or Oceanic Bonito, is the most abundant 

 of the large fishes in the Honolulu markets. It runs in great schools 

 in the open sea, where it probably spawns. Young fishes of this, 

 or other Tunnies and Albacores are almost never seen about Hono- 

 lulu, and they probably cast their spawn in the open sea. I have a 

 report apparently authentic, of a school of Aku, 96 miles long, once 

 passing Plawaii. 



The flesh of the Aku is coarse and very red. About one fourth 

 the catch is used as bait for larger and better species; much of the 

 rest is canned as Tuna. 



Genus EUTHYNNUS Lutken 



EUTHYNNUS ALLETERATUS (Rafinesque). 



This species, the Kawakawa of the markets, is a shore fish breed- 

 ing in the shallow waters of Hilo Bay, which is lined with lava 

 sand, not with coral. 



Family ACANTHOCYBIIDAE 

 Genus ACANTHOCYBIUM Gill 



ACANTHOCYBIUM SOLANDRI Cuvier and Valenciennes. 



This huge mackerel, called Ono, which reaches a length of 6 to 8 

 feet, is now common in the markets of Honolulu, being brought in
