FISHES OF HAWAIIAN ISLANDS. 687 



triidiiig; eyes separated anteriorly by a narrow groove, not half as wide as dianioter of pupil, and alike 

 in both sexes; below posterior half of upper eye the groove is narrowed to a sharj) ridge; front of up|ier 

 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 luipil, 10 present on horizontal limb of arch; vertical limb without 

 appendages, as in relati'd s[>ecies. 



First dorsal ray inserted on bliml side of snout, iinniediately aliove nostrils, the second rayon 

 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. 



Sc-ales 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 fiat -topped, its chord contained o 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 jjortion of maxillary 

 scaled. 



Color, light olive-brown, profusely covered with green spots <,if varying size, each surrounded 

 with a darker ring; series of spots, larger than the others, occur near dorsal and anal outlines, and 

 lialfway 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 Ijehind 

 arch, one at middle of straight portion, and one just in advance of caudal peduncle; dorsal and anal 

 fins finely mottled with flark, with a series of regularly arranged darker blotches. 



In 5 specimens, not including the type, there are the following tin and scale counts: Dorsal 115, 

 115, 116, 114, and 121; anal 95, 96, 96, 9:?, and 98; pectoral 14, 14, 14, 13, and 14; scales in lateral line 

 m, 94, 94, 93, and 94. 



The species was taken at the following stations: Xos. 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. 



Engyprosopon hawaiiensis .Jordan & Evermann. 



Two specimens, secured at station 4067, off the north coast of JIaui, depth 10 to 14 fathoms, seem 

 referable to this species. They are mucli 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 si<les, 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 tins are finely freckled. 



Tlie 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, V. S. Nat. Mus. 



Most nearly related to E. grandiyfjiiiiini!! (Schlegel) from Japan, readily distinguished from that 

 g|iecies 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 II; longest diameter of upjier 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; vertebr;t' 9 ^26; scales in lateral line 50, not including those on 

 ba,se of camhil fin; 12 scales in a nearly vertical series from origin of straight portion of lateral line to 

 base of dorsal fin. 



Body comparativ('ly elongate; anterior profile (in males) abruptly angulated above upper eye, 

 thence descending very steeply to near ti]) of snout, which projects, forming a re-entrant angle with
