together, close before eye, anterior simple pore and posterior cres- 

 centic. Interorbital broadly convex. Preorbital long, slender. 

 Infraorbital broad, covers cheek all but very narrow strip in lower 

 angle, with a few coarse striae. Hind preopercle edge straight and 

 slightly inclined posteriorly. Opercle narrow, deep, emarginate 

 along upper hind edge, and surface smooth. Occipital fontanel 

 well developed in frontal and parietal regions till within occipital 

 process, broad. 



Gill-opening extends forward nearly opposite front pupil edge. 

 Rakers about 6 + 12, slender, lanceolate, a little less than •filaments, 

 and latter about 3 in eye. Isthmus narrowly constricted in front, 

 its surface with slight groove, though posteriorly l^roader and convex. 

 Branchiostegals rather large, subequal. 



Scales large, well exposed in longitudinal series, of nearly uniform 

 size, and each one with few radiating striae. Row of few small 

 scales along bases of anterior anal rays. Caudal base with few 

 small scales. Free pointed axillary ventral scaly flap nearly 3 in 

 fin. L. 1. incomplete, slightly decurved. Tubes simple, only on 

 anterior portions of scale exposures. 



Dorsal origin about midway between snout tip and hind edge of 

 adipose fin, first branched ray longest, or little longer than head, 

 reaches If to caudal base. Adipose fin placed over last anal ray 

 bases, fin f in eye. Caudal well forked, pointed lobes equal, trifle 

 longer than head. Anal inserted below last dorsal ray bases or a 

 trifle nearer pectoral origin than caudal base, first branched ray 

 longest with anterior rays forming an elevated pointed lobe. Pec- 

 toral low, slender, pointed, upper rays longest and fin reaches slightly 

 beyond ventral origin. Latter slightly before dorsal origin, fin 

 pointed and extends slightly beyond front anal rays. ^>nt close 

 before anal. 



Color in alcohol largely dull or pale brownish. Scales on back 

 all broadly marked with dusk}- submarginal wide-angled streaks. 

 Each scale on predorsal, postdorsal and scales along base of dorsal, 

 with conspicuous rounded dusky or dark spot. Head brownish 

 above, also on lips. Iris slaty. Lower surface of head, and belly, 

 whitish. Along side, from head to caudal base broad area of brown- 

 ish dots, these larger and more sparse on cheek and side of abdomen. 

 Within this lateral area of dusky dots narrow brownish band extends 

 from shoulder straight to median cau lal base, where continued 

 out on middle rays of caudal as blackish streak, and streak not quite 

 wide as pupil diameter. No distinct caudal spot. Humeral region
