 lengthwise axis of bony orbit 85 and 93 ; greatest depth of body 74 and 

 102; width across body at pelvic insertion 195 and 170; tip of snout to 

 rear of maxillary 134 and 144; least width of bony interorbital 20 and 

 17; postorbital length of head 161 and 163; least depth of caudal 

 peduncle 45 and 44; length of first dorsal spine 25 and 20, and of 

 longest dorsal spine 155 and 166; of longest ray of soft dorsal 144 and 

 157, of pectoral 163 and 187, of pelvic 290 and 280, of caudal 211 and 

 238, and of anal 113 and 111; snout to dorsal origin 373 and 397, and 

 to pelvic insertion 387 and 428. 



Greatest depth 7.5 to 8.5; width of body across insertion of pelvics 

 4.8 to 5.8; length of head from tip of snout to rear fleshy edge of 

 operculum 2.8 to 2.9; all in standard length. Snout 2.9 to 3.0; eye 4.1 

 to 4.3; least width of bony interorbital 18 to 23; postorbital length of 

 head 2.2 to 2.3; longest ray of pectoral 2.0 to 2.2, of pelvic 1.4, and of 

 spiny dorsal 2.5 to 2.6; all in length of head. Least width of bony 

 interorbital in long axis of eye 5.5 to 5.9, and in length of snout 6.8 

 to 7.8. Snout in postorbital length of head 2.8 to 2.9. 



Teeth villiform, in bands on jaws and in a patch on each side of 

 vomer and palatines; tongue edentulous, its tip concave, with a 

 slight convexity near middle; lips wdthout minute fringe or tiny 

 papillae; cheek bicarinate; nostrils tubular, anterior one with a short 

 dermal flap; dorsal and ventral surfaces of head naked; opercle and 

 preopercle with some scales; interorbital concave; no pit behind 

 orbit; margin of operculum with a wide dermal flap having a deep 

 notch opposite lower preopercular spine; first three scales of lateral 

 line bearing spines; no orbital tentacle; front edge of preorbital usually 

 with a slightly projecting spine; other cranial spines and ridges 

 illustrated in figure 146 of this species; first dorsal spine scarcely 

 connected to second and contained 4)^ to 53^ in it. 



Color in alcohol. — Background pale or whitish with 4 or 5 obscure, 

 slightly brownish, crossbars on back; ventral sides whitish; dorsal 

 surface of head and body sometimes with small white blotches and 

 body with scattered, slightly darkened, small blotches or specks; 

 usually a brown-edged band across interorbital space and cheeks, 

 interrupted by eyes; pectoral, both dorsals, and caudal fins with dark 

 bars; near tip of spiny dorsal is a blackish blotch more intense than 

 bars; pelvics barred, usually persistent darker blotches on dorsal
