FISHES OF HAWAIIAN ISLANDS. 
181 
This fish appears to be fairly common. We obtained it at Honolulu, Hilo, and Waialua. It was 
obtained at Honolulu also by Jenkins, Wood, and Jordan and Snyder. 
Our numerous specimens are 1 to 10.25 inches long.

Head 4.3; depth 4.3; eye 4.3; snout 3.6; interorbital 3.4; maxillary 2; D. vii-i, 20; A. ii-i, 18. 
Body lanceolate, slender, and compressed; head moderate, profile slightly depressed over eyes; 
snout rather narrow, pointed; jaws subequal, lower being slightly the longer and prominent; mouth 
moderate, slightly oblique; small bands of setiform teeth on vomer, palatines, and tongue, those in 
lower jaw slightly larger and in 2 rows, banded anteriorly; in upper jaw similar but smaller teeth, in 
1 row, banded anteriorly; maxillary reaching posterior edge of orbit; eye slightly above median line, 
anterior, not quite so large as snout; dorsal spines broad, flat, low, longest not quite equal to eye, tip 
of last spine, when depressed, reaching origin of soft dorsal; longest soft dorsal ray 2.3 in head; caudal 
deeply forked, lobes equal; anal similar to soft dorsal, its first ray under origin of latter, longest ray 
2.65 in head; pectoral reaching tip of ventrals, 2 in head; ventrals 2.25 in head, base slightly behind 
upper anterior base of pectoral, tips reaching vent. 
Color in alcohol, bluish silvery above, white silvery below ; 3 or 4 spots slightly larger than pupil 
below the lateral line anteriorly, 7 or 8 similar spots above this line extending farther posteriorly; a 
large black blotch on anterior upper part of soft dorsal, a similar smaller spot on each following ray; 
anal pale; a spot the size of pupil on middle of second and third rays; ventrals pale; pectorals dark, 
pale at tips. 
The above description based on a specimen (No. 04033), 16.25 inches long, from Honolulu. 
This species does not appear to be common. It was obtained by Streets, also by Gunther, 
Steindaehner, Jordan and Snyder, and by the Albatross, but was not seen by Jenkins or Wood. Only 
one example was secured by us. 
Jordan and Snyder obtained one specimen, 7.5 inches long, in 1900 at Honolulu.

Genus 107. NAUC RATES Rafinesque. The Pilot Fishes. 
This genus differs from Seriola only in the reduction of the spinous dorsal to a few (4 or 5) low, 
unconnected spines. The young, called Nauclerus and Xystophorus, have the spines of the dorsals 
connected by membrane, and a more or less distinct strong spine at the angle of the opercle. A single 
pelagic species, widely distributed in the open seas.
