252. Pseudocheilinus evanidus Jordan & Evermann. Plate 43. 
Head 3 in length; depth 3.8; eye 4.5 in head; snout 3; preorbital 6.2; interorbital 5.5; D. ix, 11; 
A. hi, 9; scales 2-25-6. 
Body short, deep and compressed; head long, conic; snout long, sharply conic; anterior profile 
rising in a relatively straight line from tip of snout to nape, thence gently convex to base of caudal 
peduncle; ventral outline less convex; mouth large, horizontal, below axis of body, gape reaching 
anterior line of orbit; upper jaw with 3 pairs of anterior canines, outer strongest, curved outward and 
backward; lower jaw with a single pair at tip, similar to inner above; jaws laterally with a single 
series of smaller conic teeth; preorbital narrow, oblique; eye high up, its lower border on axis of 
body; interorbital space rather broad and flat; depth of caudal peduncle about 2 in head; scales large, 
surfaces finely striate; head, nape, and breast with large scales; lateral line following contour of back 
until under base of sixth dorsal ray, where it is interrupted, reappearing 2 rows farther down and 
continuing on 6 or 7 scales to base of caudal fin; fins rather large; dorsal spines somewhat greater than 
eye in length, spines with a sheath of large scales reaching nearly to their tips; soft dorsal and anal 
with a lower sheath; soft dorsal elevated, rays equal to snout and eye; anal similar to soft dorsal, 
second spine strongest, nearly as long as snout; anal rays somewhat longer, equaling those of soft- 
dorsal; caudal rounded, its length 1.3 in head, its base covered with very large, thin scales. 
Color in life, according to Mr. Sindo, body dull brick-red; belly and base of anal pale purplish; 
about 17 thin, thread-like longitudinal yellowish streaks along side anteriorly; dark greenish blotches 
above eye and on snout; a bluish horizontal bar on cheek, below which is a yellow bar; median line 
of throat and tip of snout brick-red; edges of opercle and preopercle bright purple; a purple stripe 
with reddish edges through middle of dorsal fin, below which the color is dull brick-red, like that of 
body, and above which the spinous dorsal is orange-yellow, the margin of the membranes bright 
cardinal-red; above the purple streak in the soft dorsal is a bright yellow streak, above which the fin is 
cardinal-red, fading gradually upward; dorsal rays purplish; tip of soft dorsal somewhat red; caudal 
rays purple, the membranes immediately next to the rays yellow, middle part dull brick-red; anal 
same as caudal; ventrals pale purplish; pectoral pale; iris scarlet-red. 
The same specimen after having been in spirits more than a year has the body light brownish 
blue; a pale streak along each row of scales, but no trace of the narrow yellowish streaks above noted; 
top of head and upper part of cheek dusky blue; opercle and edge of preopercle rich blue; dorsal, 
anal, and caudal fins bright blue, the soft dorsal pale on the outer two-thirds, dorsal rays bright blue; 
ventrals and pectoral light blue, latter darker blue at base. The color of this specimen in spirits is 
wholly different from that which it possessed in life, and it would be difficult to believe that such 
changes had taken place except that the specimen was carefully tagged when the color note in life was 
taken. 
Since writing the above, we have noticed similar changes in the Samoan species, hexatsenia. 
The blue shades are permanent in spirits, while the pink or crimson wash soon vanishes. 
The 17 thread-like streaks, mentioned in Mr. Sindo’s field notes above, have vanished entirely in 
the original type. A number of specimens taken at Laysan by the Albatross retain these marks, the 
streaks being almost white, like white threads, covering most of the side anteriorly. This is a very 
peculiar color mark, which should well distinguish the species in life. 
A single specimen, type No. 50678, U. S. N. M. (field No. 05757), was taken by Mr. Sindo in Hen- 
shaw’s pool near Hilo, a deep tide pool in the lava rocks.

pool, near Hilo, Hawaii; Snyder, op. cit. (Jan. 19, 1904) 530, (Albatross Stations 3873, 3870, and 4073, Hawaiian

253. Pseudocheilinus octotaenia Jenkins. “Aleihi lakea.” Plate XXXVII and Fig. 135. 
Head 2.8 in length; depth 3.2; eye 5 in head; snout 2.7; preorbital 6 "5; interorbital 5.75; D. ix, 
10; A. iii, 9; scales 2-23-6. 
Body moderately deep and compressed; head very long and pointed; snout long and pointed; the 
lower jaw slightly the shorter; anterior profile from tip of snout to origin of dorsal straight, ascending 
at an angle of about 35°; body deepest at origin of dorsal; mouth rather large, but narrow, nearly 
horizontal, the gape reaching not quite to vertical of eye; lower jaw with I pair and the upper jaw
