140. Pseudocheilinus evanidus Jordan & Evermann. 
Stations 3873, depth 32 fathoms, and 3876, depth 28 to 43 fathoms, between Maui and Lanai; 4073, 
depth 69 to 78 fathoms, southern coast of Oahu. 
The eye of this species, and probably of all the others® included in the genus, is remarkably mod- 
ified. The cornea is greatly thickened, the tissue being differentiated to form two lens-like structures. 
The iris and lens show no unusual characters. The retina has thickened areas which superficially 
appear as folds extending forward and backward from the point of entrance of the optic nerve. 
141. Pseudocheilinus octotsenia Jenkins. Honolulu. 
142. Cheilinus hexagonatus Gunther. 
Honolulu; station 3834, in 88 fathoms, off the southern coast of Molokai. 
The example from Molokai is 203 mm. in length. Color in life: Head on upper part and on 
snout and maxillary bright olive; chin, throat, and under parts of head blue green, shading to olive 
along a horizontal line extending backward from mouth, finally becoming brassy red on cheeks; sides 
of head with orange-rfed lines radiating from eye, fading to orange on subopercle; body orange red 
below and on lower half of sides, shading into greenish blue on back, each scale with a dark, brick 
red, semilunar mark; caudal peduncle yellowish olive, an indistinct pale band crossing it at end of 
dorsal and anal; dorsal greenish olive with two longitudinal orange bands, which broaden and become 
diffuse posteriorly; pectoral pale orange on base, becoming lilac toward the tip; ventrals reddish, with 
a wide, brown crossband; anal bright orange red, each rav dusky; rays of caudal greenish olive with 
reddish tips, the membrane pale orange. 
143. Cheilinus bimaculatus Cuvier & Valenciennes. Honolulu. 
144. Novaculichthys taeniurus (Lacepede). Honolulu. 
145. Novaculichthys kallosoma (Bleeker). 
, A single specimen, 114 mm. long, was obtained at Honolulu. It has been compared with a speci- 
men of this species recently received by Stanford University from the island of Negros, Philippine 
Islands (coll. Dr. Bashford Dean), and they are found to agree perfectly. 
146. Hemipteronotus jenkinsi Snyder, new species. Plate 10, fig. 19. 
Head, including opercular flap, 0.28 of the length measured to base of caudal; depth 0.36; depth 
of caudal peduncle 0.44 of head; eye 0.17; width of interorbital space 0.2; length of maxillary 0.34; 
D. ix, 12; A. in, 12; lateral line 22 -f- 6. 
Eye located 2.66 times its diameter above angle of mouth; mouth nearly horizontal, on a level 
with upper edge of base of pectoral, the maxillary extending to a vertical through anterior edge of 
orbit; lower jaw slightly longer than upper; lips with rather thin, fleshy folds. Outer row of teeth 
strong, conical; those on sides of jaws posterior to canines gradually decreasing in size from before 
backward; canines curving outward and forward, the lower pair, which are slightly the larger, fitting 
between the upper ones; inner teeth short and blunt, in narrow bands. Pseudo branchiae present; 
gillrakers on the first arch 6+11, short and sharply pointed. Edge of preopercle smooth. 
Head naked, except for a narrow, vertical, scaled area extending downward from eye to a hori- 
zontal passing along edge of flap of upper lip; first row with 7 scales, curving upward behind eye; 
second row with 5, the third with 4 scales. Scales of breast about half as large as those on sides of 
body; 27 series of scales between upper edge of gill-opening and caudal fin; 9 in series between inser- 
tion of anal and lateral line, 2 between dorsal and lateral line; lateral line curving upward over first 6 
scales, then following the dorsal contour, approaching the back near end of dorsal, discontinued after 
twenty-second scale, beginning again on third scale below and passing along middle of caudal peduncle. 
First two dorsal spines somewhat closer together than others, but not separated from them, the mem- 
brane being continuous; height of first spine 0.39 of length of head; the second shorter; remaining 
spines equal in height to 0.25 of length of head; height of rays 0.35; end of soft dorsal when depressed 
just reaching base of caudal fin. Anal spines small and slender, the rays equal in height to those of 
the dorsal; base of anal and also the tips of the rays when depressed extending farther posteriorly than 
corresponding parts of dorsal. Caudal rounded, the basal fourth with scales, the length 0.65 of the 
head; pectoral 0.66 of the head; outer rays of ventral filamentous, just reaching vent. 
Color in spirits, head plain, without spots, bars, or lines; a conspicuous black spot on back cover- 
ing 2 scales above sixteenth in lateral line, its distance behind the opercular flap equal to distance 
between that point and tip of snout; a yellowish white spot on side of body, rather indistinctly out- 
u P. evanidus, P. octotsenia, and P. hexatxnia have been examined.
