of posterior edge finely serrated. Teeth villiform, in broad bands on the jaws, a V-shaped patch on 
I lie vomer, ami in narrow bands on the palatines; gill rakers 5 -f 16, the length of the longest contained 
3 times in longitudinal diameter of eye; pseudobranchke present. 
Head naked, except on interoperele, preoperele, and upper part of opercle, where there are a few 
large smooth scales; scales of body ctenoid, the number in a longitudinal series immediately above 
the lateral line 54, between lateral line and spinous dorsal 3, between lateral line and anal 15; lateral 
line complete, its curve closely following that of dorsal contour of body, located on middle of caudal 
peduncle posteriorly. Third and fourth dorsal spines longest, 2.7 in head; first and sixth of equal 
length, half as long as the third; a slight space between dorsals, the spines when depressed just reaching 
base of second dorsal; spine of second dorsal measuring 3.16 in head; longest ray 1.87; distance 
between soft dorsal and base of caudal equal to width of space between anterior margin of eye and 
posterior edge of opercle; first anal spine minute, the second 3.5 in length of head; longest ray 2; 
ventral reaching a point, midway between anal opening and base of anal fin; pectoral fin rather 
pointed, its tip reaching a vertical through middle of anal; caudal forked. 
In alcohol the color is very light (in life probably red), the body with 5 rather indistinct dark 
bands, none of which reaches the ventral surface; the first on nape, second triangular in shape, 
extending from base of spinous dorsal to near middle of body, third passing from base of second dorsal 
to a point near base of anal, the fourth located just behind the second dorsal, fifth at. base of caudal; 
a narrow, dusky band passing from tip of snout to eye; a similar band from posterior margin of eye 
to edge of opercle. 
A single specimen about 5.6 inches long from the market, at Honolulu. The condition of the 
tissues indicates that the example came from deep water. Type, No. 51 87, U. S. N. M., collector

Head 2.7 in length; depth 3.1; eye 3.7 in head; snout 3.7; interorbital 4.5; maxillary 2.2; mandible 
2; gape 3; D. vii-i, 9; A. n, 8; C. 17; P. 10; scales 2-25-5; Br. 6. 
Body short and stout, moderately compressed, the dorsal and ventral outlines about equally 
curved; head rather large, conic; snout 
conic, the anterior profile very slightly 
curved from tip of snout to origin of 
spinous dorsal; mouth oblique, jaws sub¬ 
equal, the lower slightly included; max¬ 
illary long,reaching not quite to posterior 
edge of pupil, its width at tip 2 in eye, 
supplemental bone well developed; inter- 
orbital space rather broad, slightly con¬ 
vex, preorbital narrow, least width 3 in 
eye; teeth on vomer and jaws, the latter 
in villiform bands, none on palatines; 
gillrakers slender, 10 on lower limb of 
first arch; caudal peduncle compressed 
and deep, the least width about 4 in its 
depth; scales large, deep, closely imbri¬ 
cated, strongly ctenoid and loose; lateral 
line beginning at upper end of gill-opening, nearly straight to base of caudal fin, 4 scales in front of 
spinous dorsal; nape with a striated shield; edge of opercle thin and smooth; both margins of pre¬ 
operele and edge of interoperele serrate; teeth strongest at angles; a series of moderately strong teeth 
along lower edge of orbit; origin of spinous dorsal nearer snout than base of last dorsal ray; first dorsal 
spine very short, fourth longest, about 2 in head, second 2 in tire fourth, seventh 2 in second; first soft 
rays longest, 1.8 in head; caudal deeply emarginate, longest, rays about 1.6 in head; anal similar to 
soft dorsal, somewhat, smaller, its origin under last rays of soft dorsal; ventrals pointed, scarcely 
reaching vent, 1.9 in head; pectoral reaching vertical at. vent, 1.7 in lietfd. 
Color in alcohol, pale yellowish brown, darkest above; a darker brownish band extending from
