head; eye, 43 to 54; maxillary, 32 to 34; interorbital, 64 to 7. Gill- 
rakers, 6+-15, conic, firmly lanceolate, about two-thirds of gill-fila- 
ments, which 1? in eye. Scales with 61 to 65 basal radiating striae, 
and about 3 to 7 short auxiliary marginals, 60 to 68 apical radiating 
weak striae and circuli moderately fine. Color in alcohol, large ex- 
ample generally same as H. pentadactylus. Pale blue-gray line along 
median keel of snout front. Mandible with four blue-gray vertical 
lines each side. Lateral line with eighth scale jet black. Humeral 
scale with blue-gray line, also cluster of several scales about end of 
depressed pectoral with blue-gray bases, line of demarcation from 
rest of scale showing them sharply vertical. Gray line across pectoral 
base. Iris buff-yellow. Soft dorsal and anal grayish, with oblique 
whitish lines, more or less broken into small spots toward deeper 
terminal part of soft dorsal. Caudal grayish, with seven or eight 
vertical pale or whitish cross bands. Pectoral brownish above and 
terminally, otherwise pale like ventrals. Two examples, 115 to 152 
mm. Takao. 
Smaller example without blue-gray lines on head very distinct 
and black of eighth scales of lateral line extended upon base of 
one above. It certainly approaches 77. evides Jordan and Richard- 
son®*®, which we think a synonym. There are no characters shown 
in the description or figure of H. evides to ever have allowed it 
distinct from H. spilonotus. Further, no discussion of its status, 
in comparison with other species, has ever been advanced.

base and 1 more on latter; 3 scales above lateral line to third dorsal 
spine base, 10 below to spinous anal origin; snout, 24, in head; 
eye, 54; maxillary, 34; interorbital, 52. Gull-rakers, 6412, conic,

in eye. Scales with 56 or 57 basal radiating striae, and 2 to 5 
auxiliary short ones, about 44 to 60 apical radiating weak striae,

taneous fold of branchiostegal region likewise. Each side of man-
