FISHES OF HAWAIIAN ISLANDS. 
358 
Origin of dorsal over upper base of pectoral, its distance from tip of snout equal to head; dorsal 
spines flexible, all except first and second of about equal length, longest 2.75 in head, longest ray 2.4 
in head; longest anal ray 2.4 in head; caudal truncate, lobes not produced; ventral* 1.85 in head, not 
reaching vent by two-thirds its own length; pectoral 1.6 in head. 
Scales large and thin, very slightly roughened by radiating lints of granulations extending to 
margin of scales; cheek with 3 rows of scales, 6 scales in upper row, 4 or 5 in middle, 2 in lower, 
which extends upon anterior limb of preopercle; posterior limb of opercle with 2 rows of large scales; 
anterior limb with a single series; <i scales in median series before dorsal; lateral line interrupted at 1 
row of scales beyond posterior base of dorsal, pores on 19 scales, lateral line, dropping down 1 row and 
beginning on row in which long part ends, 6 pores being in the shorter part, pores being on the 2 
different but adjoining scales in the Same upward and backward row; many pores branched, a few 
single. 
Color in life, upper portion reddish-brown, lower parts, including centrals and anal, a brighter 
red; vertical fins and centrals somewhat mottled; body and head without distinct markings. 
Color in alcohol, grayish-brown, upper parts darker, edges of scales dark brown; fins all a similar 
color, the vertical fins and centrals being mottled with light and brown. 
The above description from the type, 7 inches long, obtained by Dr. Jenkins at Honolulu in 1889, 
the only known specimen until the Albatross Obtained others in 1902.

Univ.. Coll. O. P. Jenkins); ibid., XXII, 1902 (Sept. 23,1903),471 (Honolulu; same specimen); Snyder, op. cit. (Jan.

282. Callyodon jenkinsi (Jordan A Kvermann). 
Head 3 in length; depth 2.5; eye 6.5 in head; snout 2.6; preorbital 4.7; interorbital 3; D. ix, 10; 
A. hi, 9; i’. 13; scales 2-24-7. 
Body short, very deep and greatly compressed; head short, nearly as deep as long, snout short 
and blunt; mouth small; each jaw with 1 or2 blunt canines; dorsal and ventral outlines about equally 
convex; anterior profile rising rather irregularly from tip of snout to origin of dorsal; caudal peduncle 
deep, its least depth 2 in head. Scales large, deeper than long; 2 rows of large scales on cheek and 
1 row on subopercle; a row of thin modified scales at base of dorsal and anal; a few very large thin 
scales on base of caudal; lateral line ceasing under last dorsal ray, reappearing 2 rows lower down and 
continuing to base of caudal, the pores with 2 or 3 irregular branches; dorsal rays soft and flexible, 
not pungent; dorsal spines somewhat elevated posteriorly, longest a little more than 2 in head; first 
ventral spine obscure, the others soft and flexible; anal rays somewhat shorter than those of dorsal; 
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 nf 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 with 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, {taler 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 pea-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 (jilberti, from which it differs in the greater depth and the somewhat
