indistinct dusky spots on membranes of dorsal between seventh and tenth spines (one between each 
two) ; no other distinct markings on dorsal, but a tinge of yellow over the whole; ventral rays white, 
membranes yellow; anal whitish; caudal unmarked. 
Color in alcohol of some specimens, dusky-bluish above and on sides, whitish below; head with 
some purplish; spinous dorsal with the membrane dusky at tips, 3 black spots on membranes between 
seventh and tenth spines; soft dorsal, caudal and anal dusky, ventrals white, dusky at tips; pectoral

This fish is common about Honolulu, being brought into the market almost every day. It is one 
of the best of food-fishes. The above description, based chiefly upon (No. 03411) a specimen 2 feet 
long, obtained in the Honolulu market. We have 17 excellent specimens from Honolulu, Hilo, and 
Kailua, and others were obtained at Honolulu by Dr. Jenkins and the Albatross. This species is 
known not only from the Hawaiian Islands, but also from the Society Islands, Macassar, Celebes, 
Ternate, and Amboyna. Length 7 to 24 inches.

Genus 134. ETELIS Cuvier & Valenciennes. 
Body elongate, covered with large scales; eye very large; preopercle ending in 2 short, flat, lobes, 
hardly jioints; preorbital very narrow; mouth moderate, the lower jaw projecting; canines in upper 
jaw only, villiform teeth on vomer and palatines; no teeth on tongue or pterygoids; gill rakers long 
and slender; dorsal fin deeply notched, rather short, its spines 10 in number, its soft rays not scaly; 
caudal very deeply forked; head naked above, skull with the interorbital area flat, separated from the 
occipital area bv a transverse line, limiting the median and lateral crests also; frontals wide in front, 
not cavernous, simply normally perforate; supraorbital margins crenate; periotic region little convex, 
and with the bones thick, unpolished; prefrontals behind, with funnel-shaped foramina; caudal deeply 
forked; dorsal spines 10, the last shortest, the membrane falling far short of the ray following. In 
spite of the difference in the form of its dorsal, the relations of Etelis with Aprion are very close. The 
skulls in the 2 are almost identical, as has already been noticed by Poey and Gill.
