and posterior exposed as crescent. Interorbital broad, flattened. 

 Infraorbital large, covers most of cheek, surface with radiating 

 striae. Opercle striate, and subopercle projects moderately pos- 

 teriorly, both Avith striate surfaces. Occipital fontanel well devel- 

 oped, extends forward nearly to front of eyes. 



Gill-opening extends forward for last third in head. Gill-rakers 

 about 10 + 20 weak flexible filaments, about | length of gill-filaments, 

 and outer series separated by high cutaneous or cartilaginous parti- 

 tion. Gill-filaments about 2 in eye. Isthmus broad. Branchioste- 

 gals with inner shortest and outer longest. 



Scales large, firm, well exposed, in regular horizontal series, entire, 

 and more or less uniform except smaller ones on caudal base. Surface 

 of exposure of each scale pitted or with variously shaped shallow 

 cavities, not interfering with general smoothness to touch. Long 

 pointed free scaly fiap in axil of ventral. Lateral line complete, 

 midway along side, of simple tubes and each opening by pore at 

 middle of scale exposure. 



Dorsal origin midway between that of adipose fin and snout tip, 

 first branched ray longest with fourth simple but slightly shorter, 

 and fin depressed slightly more than half way to caudal base. Adi- 

 pose fin inserted about midway between depressed dorsal tip ^nd 

 caudal base, fin small. Anal inserted slightly before adipose fin, 

 first branched ray longest, loAver edge of fin slightly emarginated, 

 and when depressed reaches caudal base. Caudal well forked, lobes 

 broad, apparently (damaged) equal. Pectoral low, pointed, reaches 

 about fxr to ventral, and latter inserted behind second branched 

 dorsal ray base, reaches § to anal. Vent close before anal. 



Color in alcohol largely pale brownish, ground color mostly 

 uniform. Above lateral line four lengthwise deeper brownish bands, 

 upper three, together with additional median dorsal band, much 

 broader than lower ones, and each extending over median portions 

 of scales. L. 1. in a broad underlaid pale slaty to dusky band, not 

 quite equal to pupil diameter in width, and extending posteriorly 

 out on median rays of caudal to their tips. Each scale in dark 

 longitudinal bands, besides those in 1. 1. and for most of extent of 

 two lengthwise series of scales below 1. 1., with deep dusky-brown 

 spot formed at its base. Dark median lateral band of trunk continued 

 on head across opercle and in front to snout tip. Head brown above, 

 pale like belly below. Eye slaty. Above pectoral in course of dark 

 lateral band two ill-defined dusky spots, subequal, and each about 

 long as pu]Ml. Fins all pale or whitish in general tint, though dorsal
