eye edge. Rakers 1+4, short broad fleshy, or rather flexible, 

 tubercles, about 4 in gill-filaments. Latter 2 in eye. Suprapharyn- 

 geal pad at epibranchial of first gill-arch well developed. No pseudo- 

 branchiae. Isthmus convex, mostly concealed bj'' broad branchioste- 

 gal membrane. Branchiostegals slender, outer much longer. 



Scales large, well exposed, finely ctenoid, arranged in lengthwise 

 • series, and slightly smaller on breast than elsewhere on trunk. Fins 

 scaleless, except caudal base, and latter covered with mam^ small 

 scales. Head largely scaly. Cheek with 3 rows of scales. Occipital 

 scales extend forward to middle of interorbital. Opercles and 

 subopercles scab'. Head otherwise naked. No axillary scaly flaps. 

 Pores on preopercle, lower cheek, suborbitals, muzzle, and inter- 

 orbital small and in moderate number. L. 1. interrupted, or of two 

 divisions, upper longer, at first 3 scales from spinous dorsal origin 

 but soon separated from spinous dorsal base by one scale, and in 

 posterior portion of its extent by only half a scale. Lower or pos- 

 terior division of 1. 1. median along caudal peduncle, with tubes only 

 over 4 scales, being preceded by 3 punctures on as many scales, and 

 no tubes or punctures, continued posteriorly, or on caudal base. 

 Tubes all simple, well exposed, or extend whole extent of each scale 

 exposure. 



Spinous dorsal inserted nearer snout tip in vertical than "spinous 

 anal origin, graduated up from first or shortest to fourth, after which 

 more or less subequally long to posterior ones, which longest. Edge 

 of spinous dorsal deeply notched, and edge of each membrane forms 

 produced longer free point. Rayed dorsal with posterior median 

 rays longest, form a produced point, begins about opposite of origin 

 of lower 1. 1., and edge entire. Spinous anal be'gins about opposite 

 end of upper branch of 1. 1., spines graduated to third or longest, 

 edge of fin with cutaneous points similar to those of spinous dorsal. 

 Rayed anal similar to raj^ed dorsal, its origin also about opposite. 

 Caudal with hind margin nearly truncate or very slightly convex, 

 fin elongate in contour. Pectoral broad, median upper rays longest 

 and depressed fin extends back about opposite vent. Ventral 

 inserted close after pectoral base, spine extends | to anal origin, while 

 tip of first ray reaches rayed anal origin. Yent close before anal. 



Color in alcohol largely deep brownish on back, becoming paler 

 onh' on lower or under surface of head and abdomen. General tint 

 at present with more or less swarthy appearance. Along side of 

 snout, from its tip, then continued behind eye in straight horizontal 

 line, a black streak or line, and not continued behind to caudal
