oiiercnlar spiue alaiost obsolete ; boues of bocad rathor 

 strongly striate, but not granulate; i-cales rather 

 large ; about 5'2 pores. D. x-11, A. 10. First dorsal 

 spine not uincb shorter than second, which is 2;^ 

 in head ; caudal verj' slightly concave ; pectorals 

 longer than in any other species (except alatus), 

 reaching entirely past bases of dorsal and anal; 

 its tip subtruncate, the longest ray about the ninth ; 

 veutrals reaching a little past vent. Head 3 ; depth 

 5; color nearly plain brownish, with darker clouds; 

 no distinct spots anywhere on body or fins ; the pec- 

 torals marbled with paler EUBIO, (5. 



ii. Interorbital space very deeply concave, its width about f length 

 of eye ; a fringed cirrus above the eye ; distance from 

 supraocular spine to nuchal scales about half the 

 eye; occipital as well as nuchal spines distinct; 

 temporal ridge with a small spine ; no spine on cheek 

 bone; bones of the head with tine, sharply defined 

 striae, but no granulations ; upper opercular spiue 

 ■well developed ; 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|. Color crimson red, nearly plain ; caudal 



with two dark cross shades Ophryas, 7. 



gg. Pectoral fins 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 paii's of spines on the head ; mouth 

 large, the nuixillary 2 in head. Gill-rakers short 

 and thick in adult, slender in young, about 10 devel- 

 oped; interorbital space concave, rather broad, its 

 width, in adult, rather more than length of eye ; 

 first dorsal spiue granulated ; caudal slightly lunate ; 

 pectoral subtruucate, the second ray the longest, as 

 long as head in adult ; scales large, 48 pores iu the 

 lateral line. Head large, '^f iu length; depth 3|; 

 D. x-12. All. Color crimson, with darker clouds 

 and small spots; both dorsals with dark cross-streaks; 

 head and pectoral fins conspicuously reticulated 

 with blackish (in aclult) ; anal plain, whitish; free 



rays of pectoral unspotted Stearnsi, 8. 



ff, Preopercular spine with a distinct smaller one at the base; 'gill-rakers 



slender. 



k. Scales moderate (50 to CO pores) ; caudal fin very slightly lunate ; 



pectoral fin subtruncate. 



I, Cheek-bone without tlistinct spine at the center of radiation. 



m. Edge of preorbital granular-serrate, without distiuct spiue, 



the serrie about 12 in number on each side ; temporal 



ridges roughish but without spines; bones of the head 



with the stri* coarsely granular; mouth moderate. 



the maxillary about 2* in head; head not very broad,
