both sides, but without accessory scales on the blind side. Dorsal fin beginning on the snout, the first 
ray on the blind side, about as long as superior orbit, the rays gradually increasing in height to the 
posterior third of the fin, where they are 2.66 in head, thence rapidly decreasing to end of fin; anal 
similar, its highest rays not opposite the highest part of dorsal, but a little farther back; pectoral of 
eyed side falcate, the second ray one-fourth longer than head, produced into a filament; pectoral of 
blind side 1.83 in head; ventrals moderate, when depressed reaching past front of anal; caudal bluntly 
pointed, 1.6 in head. 
Coloration in spirits, everywhere mottled with gray and brown; the fins (except pectoral on blind 
side) marked with same colors, but the spots more nearly round and less complicated; on the colored 
side there is a large, irregular blackish blotch behind pectoral, a round black spot on the lateral line 
halfway between head and caudal fin; about 12 blackish spots at regular intervals on dorsal fin, 6 or 
7 similar ones on anal; the ventral on the eyed side marked like the anal; the colors and spots extending 
over on the blind side on the nasal bones, premaxillary,' chin, and interoperele. The skinny flap in 
the mouth between the teeth and vomer is also spotted. Length 16 inches. 
This species is common in the South Seas and has been recorded from Johnston Island. It resem¬ 
bles P. panlherinun, but is more variegated, has a larger number of anal rays (about 80) and the arch 
of the lateral line is different. The figures of P. jxt.ro and P. panthcrinus in Bleeker’s Atlas show the 
2 species well.

Genus 261. ANTICITHARUS Giinther. 
Mouth wide, or rather wide; maxillary more than one-third length of head; teeth conical, unequal, 
in a single series in both jaws; no vomerine and palatine teeth; origin of dorsal on snout; scales of 
moderate size, smooth, deciduous; lateral line strongly curved above pectoral; eyes on left side; gill- 
membranes broadly united below throat; gillrakers short and lancolate. The single Hawaiian species 
of this genus is fully described in Section II.

Genus 262. ENGYPROSOPON Gunther. 
This genus is allied to Plalophri/x, differing in the large adherent scales and the narrow interorbital 
space. Gillrakers few and short.

Head 3.8 in length; depth 1.75; eye 3.25 in head; snout 4.25; interorbital 6.3; maxillary 2.8; D.79; 
A. 56; P. i, 10; V. i, 5; scales 14-46-15. 
Body elongate, deep, rather ovoid, greatest depth about end of pectoral; head very deep, its length 
0.7 in depth; upper profile very convex in front, steep; snout short, obtuse; jaws small, produced a 
little, the mandible slightly projecting; lips rather thin; mouth curved a little, very oblique, the small 
maxillary reaching a little beyond front margin of eye; teeth in jaws very small, sharp-pointed; eyes

posterior; nostrils close together, with elevated rims; interorbital space a little more than half an eye 
diameter in width, deeply concave; gill-opening small; gillrakers rather short; scales large, finely 
ctenoid, very small on rays of vertical fins; lateral line strongly arched at first for first two-ninths its 
length, then straight to base of caudal; dorsal beginning on snout, the anterior rays free for only a 
short portion of their extremities, first 5 in head, fiftieth 2.1, this the highest region of the fin; anal 
more or less similar, first 3.25, thirtieth 2; caudal rounded, middle rays longest, 1.1; pectoral short, 
pointed, 1.4; ventrals rather broad, base of left 3, first and last rays about equal; right ventral smaller; 
caudal peduncle compressed, its depth 1.9.
