rupted portion out of the series bear tubes. They are located one over each first 2 scales in the 
series following interruption. Tubes much branched; surfaces of scales, except at posterior margin 
of each, much roughened over the whole body by striations composed of rows of minute tubercles; 
body robust and greatly compressed; an adipose lump over snout; teeth green, lower jaw included; 
a strong tooth at each angle of upper jaw; upper lip double only posteriorly, covering more than 
half of dental plate; lower lip covering less than half of dental plate; cheek with 3 rows of scales, 
upper of 7 scales, middle row of 7, the lower row of 2 scales, which extend' on lower preopercular 
limb; a series of scales along entire margin of opercle; a series of 6 scales on median line before first 
dorsal spine; lobes of caudal fin much produced, being longer than body of the fin; height of caudal 
peduncle in head 2.54; pectoral 1.5 in head, its breadth being less than half of its own length; 
ventral 1.75 in head, not reaching vent by one-half its own length, inserted on a vertical from about 
middle of base of pectoral; dorsal spines flexible; membrane of first few spines of dorsal, anal, and 
ventral somewhat fleshy on outer margin. 
Coloration in life: General color blue, the sides of body and head rosy or pink; region of body 
just below posterior two-thirds of dorsal and the caudal peduncle green; iris orange; margin of upper 
lip orange, above which it is bright blue; margin of lower lip blue, below which is an orange area; 
below this again bright blue which changes to a lighter blue; posterior to this a pink area; a pink 
wavy line from angle of mouth to eye; dorsal fin pink with upper and anterior border blue, and with 
a blue bar along each spine; anal yellowish with bright blue anterior outer and posterior margins; 
ventral blue anteriorly and pink posteriorly; caudal, upper and lower borders bright blue, interior 
portions with reticulations of pink and blue, colors almost wholly disappearing in alcohol; there 
remains the green below the posterior two-thirds of dorsal and on caudal peduncle as a pigment on the 
scales. 
One specimen of this brilliant fish was obtained by Dr. Jenkins at Honolulu in 1889. Another has 
been taken at Apia, Samoa, the latter represented in our plate. The measurements of Dr. Jenkins’s 
specimen are as follows:
