scales moderate (about 50 pores). D. VIII-13; A. 11. First dorsal spine 



"longest, 1§ in head; caudal subtruncate; pectorals nearly twice as long 



as head, reaching nearly to last rays of dorsal ; ventrals about reaching 



to vent; head 3 in length; depth 4 J. Color crimson red, nearly plain; 



caudal with 2 dark cross shades. opheyas, 2493. 



kk. Pectoral tins short, not reaching beyond middle of dorsal; head much smoother 



than in any other species, the bones of the head faintly striate, with small 



granulations; the cranial spines little developed; the supraocular, occipital, 



and temporal spines wholly wanting, there being only 3 pairs of spines on the 



head ; mouth large, the maxillary 2 in head. Gill rakers short and thick in 



adult, slender in young, about 10 developed ; interorbital space concave, rather 



broad, its width, in adult, rather more than length of eye; first dorsal spine 



granulated; caudal slightly lunate ; pectoral subtruncate, the second ray the 



longest, as long as head in adult; scales large, 48 pores in the lateral line. 



Head large, 2§ in length; depth 33. D. X-12; A. 11. Color crimson, with 



darker clouds and small spots; both dorsals with dark cross streaks; head 



and pectoral fins conspicuously reticulated with blackish (in adult) ; anal 



plain, whitish ; free rays of pectoral unspotted. steaensi, 2494. 



ij. Preopercular spine with a distinct smaller one at the base; gill rakers slender. 



q. Cheek bone without distinct spine at the center of radiation; edge of 

 preorbital granular-serrate, without distinct sjiine, the serrse about 

 12 in number on each side; temporal ridges roughish but without 

 spines ; bones of the head with the strise coarsely granular; mouth 

 moderate, the maxillary about 2J in head; head not very broad, the 

 spines above, except the nuchal spines, not conspicuous ; gill rakers 

 long and slender, 15 to 20 developed ; head 2 J in length ; depth about 

 4. D. X-12; A. 11. Coloration brownish ; side with a very distinct 

 dusky bronze band below the lateral line and parallel with it, this 

 becoming broken posteriorly into a series of roundish dark spots; 

 some dark streaks and clouds below this stripe; fins with dark 

 clouds, the soft dorsal with 2 dark blot<'hes, which extend as bars 

 on the back : head with scattered dark spots ; dusky area below eye. 

 r. Pectoral with its rays each crossed by fine black bars, these especially 

 distinct«toward the base of the fin; free rays spotted; scales com- 

 paratively small, 10+1 + 23 in a vertical line from last dorsal spine 

 to vent; interorbital area broad and almost flat, its width a little 

 more than length of eye; first dorsal spine granulated; second 

 spine 2f in head ; pectorals about \ the length of the body. 



STEIGATUS, 2495. 



rr. Pectoral fin with its rays all plain blackish; free rays plain dusky; 

 scales larger, 8+1+21 in a vertical line from last dorsal spine to 

 vent; interorbital space more deeply concave, its width in adult 

 not quite length of eye ; first dorsal spine nearly smooth ; second 

 spine 3 in head ; pectorals a little more than \ of the body. 



EVOLANS, 2496. 

 qq. Cheek bone with a spine (small in the adult, larger in the yoang) at 

 the center of radiation, this rarely obsolete in old examples, 

 s. Spines on bones of head moderate, not knife-like; preorbital with a 

 series of serrse and 1 or more bluntish spines. 

 t. First 3 dorsal spines little if at all serrate; pectorals reaching 

 past middle of anal, their length not quite \ the body ; gill 

 rakers rather long and slender, about 10 developed; maxil- 

 lary 2f in head; a bluntish spine on edge of snout behind 

 the serrpe ; behind this, 1 or 2 smaller ones, at least in the 

 young; usually a small spine on cheekbone; a shallow groove 

 behind the eye evident; interorbital area rather narrow, con- 

 cave; preocular, supraocular, occipital and nuchal spines 

 rather prominent. Dorsal spines high, the third 2J in head;
