133. Thalassemia umbrostigma (Ruppell). “ Olali 
Color in life (field No. 118, 4.5 inches in length), general color brown; side of body with 2 longi- 
tudinal rows of light-green oblong patches, of which the vertical length of each is greater, breadth of 
| each less than diameter of eye; 2 bright blue stripes from upper margin of eye, the anterior meeting 
its fellow from other eye, the posterior not quite meeting its fellow; chin blue; blue spot on opercle; 
blue stripe around snout; belly blue; dorsal brown, with greenish-blue longitudinal stripe; anal 
similar to dorsal; caudal with alternating stripes of brown and green. 
Another example (field No. 154, 7.25 inches in length), colors of body bright green and red, the 
red on head broken up into spots instead of in bands; blue spot on anterior dorsal. 
Another example (field No. 155, 7 inches long) shows an arrangement of color much like that of 
No. 154, with the exception that it has bright blue where the other is green, and has no dots and 
bands on the head. The difference in color from No. 154 is so great that the native fishermen call 
I; this form by a different name. Specimens Nos. 156 and 157 form, however, a gradation in color pattern 
intermediate between Nos. 154 and 155. 
Quite abundant at Honolulu. Eleven examples, 5.5 to 11.5 inches in length, were taken.

134, Thalassoma duperrey (Quoy & Gaimard). “Hinalea Lauli.” 
Thirty specimens of this fish, the longest 7 inches, were taken by me; 3 by Dr. Wood, 3 by the 
Albatross in 1896, and 4 by Jordan & Snyder. An examination of Quoy & Gaimard’s description and 
figure, based on a specimen from the Hawaiian Islands, leaves no doubt of the identity of my specimens 
with this species. Many young of this species were taken in the coral rocks which show no evidence 
of the color markings of the adult, but series of sufficient completeness shows the gradual development 
j of the adult color pattern. The following is a description of an example 2.75 inches in length. 
Head 3.4 in length; depth 3.5; eye 4.75 in head; snout 3.5; interorbital about equal eye; D. vnr, 
I 12; A. ii, 11; scales 3-28-8, 20 pores before the bend. Body short, moderately compressed; dorsal 
' and ventral outlines evenly convex; head small, longer than deep; snout moderate, pointed; mouth 
J small, horizontal, entirely below axis of body; lips broad, the upper overhanging the lower in the 
[ closed mouth; preorbital narrow and oblique; eye small, lower edge touching axis of body; interorbital 
[ moderately broad, little convex; caudal peduncle much compressed, its least depth 2 in head; dorsal 
spines low, the last the longest, 3 in head; soft dorsal somewhat higher, about 2 in head; anal similar 
i to soft dorsal, slightly higher; caudal truncate or very slightly rounded; ventrals short, reaching 
| half-way to origin of anal; pectoral broad, reaching slightly past tips of ventrals, its length about 1.3 
in head; scutes large, firm, with thin, flexible edges; scales on nape and breast but little reduced; 
head naked, except a patch of 6 or 7 scales on upper angle of opercle; head with numerous 
I conspicuous pores and tubes, a series radiating from orbit on its under side, and 3 conspicuous ones on 
opercle; lateral line complete, beginning at upper end of gill-opening parallel with the dorsal outline 
to beneath fourth dorsal ray from last, where it curves downward 2 rows and continues to base of 
caudal; pores on upper portion mostly 3-branched, lower portion mainly single. 
Color in alcohol, dark olive brown on head, back, and sides, paler below; spinous dorsal pale 
dusky with black on membranes between first and fourth spines; edge of dorsal pale with a narrow 
marginal dark line; anal dusky; caudal dusky; ventral paler; pectoral pale, somewhat dusky; the 
upper rays with a long 'dark blotch, less distinct than in most species, obsolete in some specimens; 
axil with a dusky spot. In some specimens the boundary between the dark of upper parts and the 
pale of belly is more marked. 
This is perhaps the most abundant labroid at Honolulu.

135. Thalassoma obscurum (Gunther).

plain. Abundant at Honolulu. Nineteen specimens, 4.4 to. 9.75 inches in length, were obtained.
