SHORE FISHES OF THE HAWAIIAN ISLANDS.

134 . Thalassoma duperrey (Quoy & Gaimard). 
Honolulu; Puako Bay, Hawaii; station 3881, between Maui and Molokai; Laysan Island. 
The young have a black stripe, about as wide as the eye, extending from the snout to the upper 
half of the base of caudal, where its end is slightly broadened and rounded. Below and parallel 
with the dark stripe is a pinkish white one of about equal width. Some specimens have a narrow, 
short, indistinct, dusky stripe below the latter. With increasing age the stripes become indistinct 
and disappear, the general color grows darker, while the broad, light band behind the head appears. 
The caudal is at first rounded, later becoming concave, the upper and lower rays being much produced 
in the adult. The colors here noted are of alcoholic specimens. 
135 . Thalassoma umbrostigma (Riippell). Laysan Island. 
136 . Thalassoma ballieui (Vaillant & Sauvage). Honolulu; Laysan Island. 
137. Gomphosus varius Lacepede. Honolulu. 
138 . Gomphosus tricolor Quoy & Gaimard. Honolulu; Puako Bay, Hawaii. 
139 . Cirrhilabrus jordani Snyder, new species. Plate 10, tig. 18. 
Head measured to end of opercular flap 0.36 of length; depth 0.29; depth of caudal peduncle 0.14; 
length of snout 0.32 of head; eye 0.25; interorbital space 0.23; D. xi, 8; A. in, 8; scales in lateral line 
16+8; between lateral line and dorsal 1; between lateral line and anterior part of anal 5. 
Snout pointed; cleft of mouth equals 0.66 diameter of eye; 6 rather widely spaced canines in upper 
jaw; inner pair projecting forward; the others, of which the outer pair are much the longer, curve out- 
ward and backward; 2 small canines in lower jaw; no posterior canines; other teeth very small, sharp, 
and closely apposed; preoperele with a finely serrated margin. Cheeks and opercles with scales; bases 
of dorsal and anal, each with a row of long, pointed scales; 3 large scales covering the greater part of 
basal half of caudal. Dorsal and anal fins high. Dorsal spines slender, the longest (posterior ones) 
equal in length to twice diameter of eye, each with a fleshy, spine-like prolongation, a continuation 
of the thickened membrane surrounding the spine, extending upward and backward and acting as a 
support for the membrane which extends above spines. First ray equal in height to preceding spine 
and its thickened attachment, the following rays gradually growing shorter. Anal spines with thick- 
ened membranous attachments similar to those of dorsal, the rays longer than the spines, their length 
contained about 1.5 times in head; caudal rounded; ventrals sharply pointed, not greatly elongated, 
reaching to vent when depressed; upper rays of pectoral longest. 
Color in spirits plain, a few small, white spots below base of dorsal. 
Flesh color in alcohol, probably red in life; a pale purple stripe indistinctly outlined extends 
along body between base of dorsal and lateral line; a few small white spots scattered along the back 
above lateral line; three distinct, narrow, light stripes along side of abdomen. Fins plain, probably 
yellow in life; anal with a narrow dusky band on margin. 
The specimen described is a male, type, No. 50878, IT. S. Nat. Mus., from station 3876, between 
Maui and Lanai; depth 28 to 43 fathoms. 
Other examples, females from the same locality, among them cotypes No. 7728, ichthyological 
collections Stanford University, have the spinous dorsal lower than the rayed portion of the fin. The 
thickened portions of the membrane are less developed. The anal has no dusky border. 
Named for Dr. David Starr Jordan.
