Head deep, compressed, mostly flattened sides scarcely constricted 



below, and lower profile little more inclined than concave upper. 



•Snout short, convex over surface, end rather obtuse, projecting beyond 



mandible, and length about f its width. Eye large, circular, not 



high, and center near first third in head. Premaxillary protractile 



down and forward. Lips moderately thick, fleshy. Maxillary 



;small, mostly concealed, to hind nostril. No barbel. Mandible 



depressed, small, included in upper jaw, and rami well elevated inside 



mouth. Tongue fleshy, little distinct, adnate. Jaw edges rather 



pliable, blunt. Nostrils large, together, anterior circular and with 



'cutaneous posterior margin exposing posterior in narrow crescent. 



Jnterorbital broadly convex. Preorbital small, trapezoidal, length 



H in eye. Postorbital width about J of eye, postero-infraorbital 



wider, and antero-infraorbital much narrower. Posterior margin 



•of preopercle convex, inclined a little forward. 



Gill-opening forward about last third in head, or about to hind 

 preopercle margin. Rakers about 2 + 6? short weak fleshy points, 

 much less than filaments, and latter about § of eye. Pseudobranchise 

 little less than filaments. Teeth 5-5, compressed, broad ends curved 

 over in a slight hook, and with moderately broad grinding-surfaces, 

 their edges crenulated. 



Scales large, rather narrowly imbricated on sides of body, and 

 exposed in series parallel with 1. 1. Scales on edges of body and breast 

 .a trifle smaller than others. Pointed axillary ventral scale with greater 

 outer portion free, equals ^ of fin. L. 1. complete, straight, not decurved, 

 :and tubes simple, extending about first half of each exposed scale. 



Dorsal origin about midway between snout tip and caudal base, 

 •first branched ray (damaged) evidently longest, depressed fin about 

 § to caudal base. First 3 anterior dorsal rays spinous, straight, 

 Tobust. Anal inserted about opposite base of eighth branched dorsal 

 ray, its first branched ray longest, depressed fin f to caudal base. 

 First 2 anterior anal rays spinous, straight, robust. Both dorsal and 

 :anal depressible in a scaly basal groove. Caudal forked, lobes pointed.. 

 Pectoral short, rounded or expanded distally, f to ventral. Latter 

 "inserted a little before dorsal, and about to anal. Vent about midway 

 In postcentral region, and ensheathed behind base of the fleshy ovi- 

 positor, latter beginning just behind ventral bases and reaching back 

 well beyond anal front. 



Color in alcohol faded dull brownish almost entirely, with traces 

 of slight silvery sheen, especially on opercle. Lower part of body 

 scarcely paler. Back sprinkled with minute pale dusky dots. Iris
