caudal shallowly lunate, the outer rays not greatly produced; ventrals moderate, 1.6 in head, not 
reaching to origin of anal by a distance equal to two-fifths their length; pectoral broad, 1.2 in head. 
Color of a nearly fresh specimen, bright blue-green, brightest on posterior half of body, each 
scale broadly edged with reddish brown; lower anterior part of body reddish brown, with traces of 
blue-green; top of head brownish red or coppery, a broad deep blue-green band on the upper lip, 
extending on side of head to below eye; lower lip with a narrow brighter blue-green band connecting 
at angle of mouth w r ith the one from upper lip; chin with a broad coppery-red bar, followed by a 
broader bright blue-green one; caudal green, median part pale, banded with green spots; dorsal 
bright green at base and tip, the middle pale greenish, translucent; anal similar, the distal band 
broader; pectorals and ventrals deep vitriol-green with whitish markings. 
Color in alcohol, dirty greenish, side with about 8 longitudinal series of greenish blotches; head 
olivaceous above, paler on cheeks; upper lip broadly pea-green at edge, this color continued backward 
to under eye; edge of lower lip pale green, continued around angle of mouth uniting with the same 
color from upper lip; chin with a broad, pale crossbar behind which is a broader, pale green one 
which extends up on cheek nearly to orbit; back of this is a still broader, white crossbar interrupted 
in the middle by greenish; subopercle and lower edge of preopercle with a large, irregular, green patch; 
a median green line on breast to base of ventrals; dorsal green at base and along edge, the middle 
portion paler; anal similar to dorsal, the green border broader; caudal bright [tea-green on the outer 
rays, the inner ones pale with 4 or 5 cross-series of green spots, tips of rays darker; ventrals pale 
green, the edges dark pea-green; pectoral pale green, darker green on the upper rays. 
This species is related to Scarus gilberti from which it differs in the greater depth and the somewhat 
different coloration. It is also related to Scarus lauia, but differs in the much greater depth, the 
less produced caudal lobes, the greater width of the green head markings, and the color of the fins. 
Only one specimen was obtained, type, No. 50647, U. S. N. M. (field No. 02944), 14 inches long, 
obtained at Honolulu, June 6. Named for Dr. Oliver P. Jenkins.

10; A. iii, 9; P. 13 on one side, 14 on other; scales 2-25-6. 
Body short, stout and compressed; head heavy; snout rather short, bluntly rounded; dorsal and 
ventral outlines about equally arched, anterior profile slightly concave before the eyes; nape strongly

breast with large scales; cheek with 2 rows of large scales, about 7 scales in each; subopercle and 
lower limb of preopercle each with a row of scales; opercle with large scales; lateral line broken under 
last dorsal ray, reappearing one row lower down and continuing to caudal fin, the pores w r ith 2 to 4 
branches; a series of these oblong scales along base of dorsal and anal; base of caudal with 3 or 4 very 
long, thin scales. Dorsal spines soft and flexible, not pungent, the longest about 2.7 in head; soft 
portion of dorsal somewhat higher, especially posteriorly where the rays are about 2.4 in head; anal 
spines soft and flexible, the first obscure, the third about 4.3 in head; anal rays higher, the last but one 
longest, 3 in head; caudal deeply lunate, the 3 or 4 outer rays above and below produced, length of 
middle rays 2.3 in head, or 2 in outer rays; ventrals moderate, not reaching vent, 1.9 in head; pectoral

Color in life, head brownish yellow before eyes, the jaws lighter yellow; cheek washed with brown- 
ish and blue, throat greenish; nuchal and opercular regions brownish orange; body salmon-color 
above, the belly lighter yellow, most of the scales with an edging of greenish blue; a deep blue line

rows of scales; the center of each scale in the first 5 rows greenish blue; under parts pale rosy, with
