FISHES OF HAWAIIAN ISLANDS. 
345 
tips reaching scarcely half way to origin of anal; pectoral short, free edge rounded, its length a little 
greater than that of ventrals. 
Scales large; lateral line continuous from upper end of gill-opening to posterior end of dorsal fin, 
where it curves downward 2 rows, continuing to base of caudal fin; tubes of lateral line numerously 
and widely branched, the branches 4 to 6 or 7 in number, a few additional tubes at the bend of lateral 
line; one series of about 4 scales on cheek between which and eye are several long tubes; opercle with 
a series of large scales on basal portion; 4 scales on median line in front of dorsal fin. 
Color in spirits, dirty rusty brown, paler below, upper part of side above lateral line with a series 
of about 6 roundish whitish spots larger than pupil; a similar series of about 4 spots on first row of 
scales below lateral line; lower part of. side with 2 or more similar spots; side of head and body 
Fig. 117. — Scaridea batia Jenkins; from the type. 
with a few scattered, smaller, less distinct whitish spots; dorsal tin indistinctly mottled with light and 
brownish; membrane between flrst and second spines blackish at the center; anal and caudal rather 
uniformly plain pale brownish without distinct markings; pectoral and ventrals lighter brownish; 
base of pectoral darker brown. 
This species differs from Scar idea zonarcha in the greater depth of body, the much greater distance 
between tips of ventrals and origin of anal, the greater distinctness of the w hite spots on body, the less 
distinct mottling of the dorsal tin, and the entire absence of mottlings on anal and caudal. 
The only specimen know n is the type, No. 50852, U. 8. National Museum (original No. 1985), 10 
inches long, obtained by the Albatross at Honolulu in 1896. 
Scaridra balia Jenkins, Bull. U. S. Fish Comm., XXII, 1932 (Sept. 23, 1903), 469, Honolulu. 
Genus 170. CALLYODON Gronow. 
Lower pharyngeals spoon-shaped, ovate-oblong, transversely concave; teeth in each jaw fully 
coalescent, appearing as tessellations on the surface; jaws w ith distinct median suture; edges of jaw- 
even, the teeth whitish, or rosy, in color; upper pharyngeals each with 2 rows of teeth; gill- 
membranes scarcely united to the narrow isthmus, across which they form a broad fold; dorsal spines 
flexible, scarcely different from the soft rays; upper lip laterally double, the interior fold becoming 
very narrow or obsolete mesially; lower jaw included in the closed mouth; lateral line interrupted 
posteriorly, beginning again on the next series of scales below ; tubes of lateral line scarcely branched; 
scales on cheek in 2 to 4 rows; scales in front of dorsal on median line 6 to 8; dorsal ix, 10; anal hi, 9 
in all species; scales £-24-6; body robust. 
Species very numerous, mostly of large si/e, found in nearly all tropical seas.
