Head witli flap in length of body to base of caudal 3.5, in total length 1 ; depth 3.1(1, 3.66. D. ix, 12 
A. hi, 12 (in one specimen in, 11). Scales 3-27-8. Outline elliptical, body compressed, somewhat 
elevated; teeth 2-2, posterior canine in each jaw. Type No. 6131, L. S. Jr. University Museum. 
Coloration in life : Each scale with a dark-red crescent spot, convex anteriorly, this spot bordered 
posteriorly with blue; head bright-red, with bright-green stripe on median line from snout to base of 
caudal, a bright-green stripe along upper margin of eye on to body, where it continues more or less 
distinctly just above lateral line about half the length of body; a narrow green line from snout to 
middle of anterior margin of eye, a bright-green stripe from near angle of mouth along lower margin 
of eye to opercular flap, where it is confluent with a wide bright-green band from the chin backward 
over lower limb of preopercle and the subopercle and opercle; this green gradually shading into 
blue on throat and belly; a black spot behind eye surrounded by bright-green, with red spots in some 
specimens; dorsal tin dark-red, with a row of dark-green oblong spots on proximal border, one spot 
on each iuterspinous membrane, a green longitudinal band on outer portion, with a very narrow outer 
margin of light-blue; a black spot in membrane between first and second spines; in one specimen a 
double blotch between first and third soft rays, a median row of green spots. The detail of markings 
in this flu varies in the three specimens. Anal dark-red with a green band along central portion, outer 
margin with narrow blue line; caudal dark-red with a crqssband of bluish-green at the base, with 
two or three other crossbands often broken up into spots of green with orange centers; ventrals blue, 
with dark line on anterior portion ; pectorals pale-red, with base and axils bright-green. 
Coloration similar to that of Jitlis ornatissimus Garrett. Garrett’s description is incomplete, but 
shows that this fish differs in marked points of coloration, notably in conspicuous black spot behind 
eye, spot on anterior portion of dorsal, form of markings on the scales, and in number of anal rays. 
A very brilliant tish, taken from the coral reefs, apparently not very common. Three specimens 
were taken by me, measuring 140 mm., 130 mm., and 120 mm. Detailed measurements of the last are
