above and narrow below. Jaws with broad bands of small or fine 

 uniform conic teeth, largely depressible and directed inwards. No 

 other teeth. Buccal folds inside mouth moderately broad. Tongue 

 depressed, attenuate, and free in front. Mandible broad, shallow, 

 well produced in front beyond snout tip, rami not elevated inside 

 mouth, though outer lip forms broad fleshy pocket to receive upper 

 at rictus. Nostrils simple, lateral or on side of snout about last 

 third its length. Interorbital level. Preopercle with entire edge, 

 slightly inclined forward above. Opercle ends in rather pointed 

 cutaneous flap above. 



Gill-opening extends forward about opposite last f in eye. Rakers, 

 1 + 12 asperous short broad tubercles, about 3 in gill-filaments. 

 Latter about If in eye. Isthmus narrow, constricted, surface convex. 

 Branchiostegals slender, outer longer, and membrane rather broad 

 across isthmus. 



Scales large, well exposed, smooth on head, predorsal region, and 

 region embracing bases of dorsal fin, though this greatly narrowing 

 posteriorly, also on breast and belly, other regions with finely ctenoid 

 scales. Fins scaleless, except caudal base, and on latter scales 

 smooth and quite small. Cheek with 9 series of scales. Occipital 

 scales extend forward only to hind edge of interorbital. Opercles 

 and subopercles scaly. [Head otherwise naked, though with a number 

 of mucous pores, especially above. L. 1. interrupted, or in two 

 divisions, upper much longer, scales larger than those surrounding. 

 Upper division of 1. 1. concurrent with dorsal profile, replaced below 

 by median lower division. Tubes simple, and all well developed or 

 extending completely across exposure of scale. 



Spinous dorsal inserted about midway between snout tip and 

 seventeenth dorsal spine base, first spine shortest and all others 

 graduated up to twelfth and then subequal, though last spine longest. 

 Edge of spinous dorsal with membranes ending in cutaneous points, 

 free and projecting above tips of spines. Rayed dorsal higher than 

 spinous portion, rays graduated to fourth and fifth branched, which 

 longest and produced in filamentous point, edge of fin entire. Spi- 

 nous anal inserted slightly before second simple dorsal ray base, 

 spines graduated up to third which longest, and edge of fin with 

 cutaneous points like spinous dorsal. Rayed anal with seventh 

 ])ranched anal ray longest, preceding rays subequally shorter, and 

 edge of fin entire. Caudal rounded, elongate. Pectoral broadly 

 expanded, median rays longest, and fin depressed extends slightly 

 less than half way to anal origin. Ventral inserted close behind anal
