which forms an angle at mandibular articulation. Snout convex 

 over surface, upper profile straight, and length about £ its width. 

 Eye circular, moderate, a little high, and center near first third in 

 head. Mouth moderate, well inclined. Premaxillaries protractile 

 anteriorly down. Lips firm, scarcely distinct from jaws. Maxillary 

 well inclined to hind nostril. Mandible prominent, depressed, pro- 

 truding beyond snout tip, moderate, and rami a little elevated inside 

 mouth. Tongue fleshy, not free. Jaw edges firm, scarcely trenchant 

 and laterally on each side of upper a broad notch. Nostrils large, 

 together, anterior circular with rather broad posterior cutaneous 

 margin exposing posterior in narrow crescent. Interorbital broadly 

 and evenly convex. Preorbital moderate, trapezoidal, length 1^ 

 in eye. Postorbital width 2^ in eye. and infraorbitals scarcely more. 

 Posterior preopercle margin vertical, or sloping but slightly back- 

 wards below. 



Gill-opening forward nearly midway in head, not quite to hind eye 

 margin. Rakers about 2 + 8? firm points, about 4 in filaments, 

 and latter about If in eye. Pseudobranchise a little less than fila- 

 ments. Teeth 1, 3, 5-5, 3, 1, ends hooked, and larger with slight 

 smooth grinding-surfaces, edges also smooth. 



Scales large, narrowly imbricated, on sides of body, disposed in 

 even longitudinal series, and smaller on edges of body and breast. 

 Axillary ventral scale short, little pointed, mostly adnate. L. 1. 

 decurved slightly below lowest third in greatest body depth, incom- 

 plete, and only extending opposite ventral base. Tubes short, each 

 over about first § of exposed scale, simple, and 12 in number. 



Dorsal origin nearly midway between hind pupil margin and caudal 

 base, first blanched ray longest, depressed fin If to caudal base. 

 Anal inserted just behind dorsal base, fin similar, depressed 1£ to 

 caudal base. Caudal emarginate, lobes equal, little pointed. Pec- 

 toral | to ventral, upper rays longest. Ventral inserted a little before 

 dorsal, nearly midway between tip of muzzle and caudal base. Vent 

 simple, close before anal. 



Color in alcohol generally dull brownish, a little paler below. Back 

 and upper surface of head sprinkled with minute dusky dots, becoming 

 a little more sparse and larger on opercle and longitudinally along 

 middle of side, most pronounced superiorly. Concurrent with verte- 

 bral column a dusky streak, diffuse largely, and becoming more dis- 

 tinct and emphasized along caudal peduncle side, but fading out at 

 pale caudal base. Fins all pale brownish, dorsal, caudal and upper
