FISHES OF HAWAIIAN ISLANDS. 
687 
trading; eyes separated anteriorly by a narrow groove, not half as wide as diameter of pupil, and alike 
in both sexes; below posterior half of upper eye the groove is narrowed to a sharp ridge; front of upper 
eye over front of lower pupil; no spines or tubercles in either sex; gill-rakers slender, the longest 
half or less than half diameter of pupil, 10 present on horizontal limb of arch; vertical limb without 
, appendages, as in related species. 
First dorsal ray inserted on blind side of snout, immediately above nostrils, the second ray on 
dorsal ridge; first few dorsal rays free from membrane for about half their length, but none of them 
produced, the first shorter than succeeding rays, which increase regularly; left ventral inserted upon 
pre-anal ridge, the membrane of last ray joining body immediately to left of first anal ray; pectoral 
of colored side nearly twice as long as that of blind side. 
Scales very small, not closely adherent, rather weakly ctenoid on the left side, cycloid on the right; 
lateral line present on left side only; anterior arch flat-topped, its chord contained 5 times in straight 
portion of lateral line; interorbital groove naked immediately above middle of upper eye, elsewhere 
scaly; symphyseal portion of mandible and terminal half of snout naked; exposed portion of maxillary 
scaled. 
Color, light olive-brown, profusely covered with green spots of varying size, each surrounded 
with a darker ring; series of spots, larger than the others, occur near dorsal and anal outlines, and 
halfway between these and lateral line; a short dash in front of upper eye and one behind it; a con- 
spicuous sharply angulated streak connecting lower anterior margin of upper eye with anterior margin 
of lower eye; four conspicuous spots on lateral line, two of these near together, immediately behind 
arch, one at middle of straight portion, and one just in advance of caudal peduncle; dorsal and anal 
fins finely mottled with dark, with a series of regularly arranged darker blotches. 
In 5 specimens, not including the type, there are the following , fin and scale counts: Dorsal 115, 
115, 116, 114, and 121; anal 95, 96, 96, 93, and 98; pectoral 14, 14, 14, 13, and 14; scales in lateral line 
93, 94, 94, 93, and 94. 
The species was taken at the following stations: Nos. 3859, Pailolo Channel, 138 to 140 fathoms; 
3938, near Laysan Island, 148 to 163 fathoms; 3957, near Laysan Island, 173 to 220 fathoms; 4079, off 
the north coast of Maui, 143 to 178 fathoms. 
Eng-yprosopon hawaiiensis Jordan & Evermann. 
Two specimens, secured at station 4067, off the north coast of Maui, depth 10 to 14 fathoms, seem 
referable to this species. They are much lighter in color than the type specimen from Honolulu, and 
are very finely mottled with light gray and brown. A series of inconspicuous dark spots along the 
middle of sides, and others near base of dorsal and anal, can not be detected in the type. On close 
examination, however, the type shows the finer mottlings. Indistinct dark and light bars traverse 
the interocular space. The fins are finely freckled. 
The fin rays are: Dorsal 79, 80; anal 57, 58; scales in lateral line 45, 46. 
Engyprosopon xenandrus, new species. Fig. 270. 
Type, a male, 86 mm. long, from station 3849, off the south coast of Molokai, depth 43 to 73 
fathoms; type, No. 51651, U. S. Nat. Mus. 
Most nearly related to E. grandisquamis (Schlegel) from Japan, readily distinguished from that 
species by the larger eye, provided with a fringed membrane in the male, by the much narrower 
interorbital space in the female, by the more elongate body, the more numerous fin-rays, and by 
certain details of color. 
Length of head 29 hundredths of total length without caudal; length of snout, from lower eye 7, 
from upper eye 17; length of maxillary 11; longest diameter of upper eye 8; interorbital width 9 (2 in 
a female cotype of equal size); greatest depth of body 55; least depth of caudal peduncle 12; longest 
dorsal ray 15; longest anal ray 13; length of caudal 22; length of pectoral 20; chord of curve of lateral 
line 16. D. 88; A. 66; P. 12; V. 6; vertebrae 9 + 26; scales in lateral line 50, not including those on 
base of caudal fin; 12 scales in a nearly vertical series from origin of straight portion of lateral line to 
base of dorsal fin. 
Body comparatively elongate; anterior profile (in males) abruptly angulated above upper eye, 
thence descending very steeply to near tip of snout, which projects, forming a re-entrant angle with
