BULLETIN OF THE UNITED STATES FISH COMMISSION. 
This large and brilliant species, described originally from these islands, is . very common in the 
markets of Honolulu and Hilo, from which places we have numerous specimens 5.8 to 15.75 inches 
long.

Genus 158. CORIS Lacepede. 
Body compressed, oblong, covered with moderate or small scales, 50 to 69 in the lateral line; 
head scaleless; lateral line not interrupted; posterior canine tooth absent or not; dorsal ix, 12; anal in, 
12; anterior dorsal spines usually produced and flexible; caudal rounded. 
Polynesia, the species few; deeply colored fishes of the coral reefs. 
The genus Coris, as understood by Gunther, differs from llalichares in its small scales. It com- 
prises a great variety of forms, and is divisible into 6 well-marked genera or subgenera, as follows: 
a. Scales in lateral line 50 to 85. 
b. Posterior canine obsolete; head naked; caudal rounded; scales 60 Coris, p. 310 
bb. Posterior canine present. 
c. Head with a patch ol scales behind the eye; caudal rounded; scales 50 Ophihalmolepis, p. 310 
cc. Head entirely naked. 
d. Caudal rounded or truncate. 
e. Scales 55 to 65 Hcmicoris, p. 310 
. cc. Scales TO to 85 Julis, p. 304 
dd. Caudal forked, the lobes much produced in the adult; scales 73 . Pseudocoris, p. 310 
aa. Scales in lateral line about 120; body oblong; head naked; no posterior canine Hologijmnosus, p. 310 
Of these groups we here recognize Coris, Julis, Oplhalmolepis (iineolata) , and 1 1 ologyrnnosus ( fasci - 
atus) as distinct genera. It is not unlikely that Pseudocoris (heteroptera) is entitled to similar rank.

tube; first dorsal spine elongate, filamentous, 3.7 in body; longest dorsal ray 2.2 in head; third anal 
spine longest, 4.3; longest anal ray 2.25; caudal rounded, 1.6; ventrals long, pointed, 1.7; scales rather 
large, thin, cycloid; lateral line high along back, descending below last dorsal rays to middle of sides 
of caudal peduncle. 
Color in life (No. 03260) light olive-brown, with a silver streak on each row of scales, about 22 in 
number, some scales with a light bluish-green central spot forming irregular stripes, the one above lat- 
eral line most distinct, the interspaces forming golden stripes; behind tip of pectoral about 5 short 
vertical irregular bars of golden, alternating with violet, behind these faint violet stripes alternating
