 gill arch usually 2-f 5. 



Head depressed, body compressed posteriorly; gill membranes ex- 

 tending moderately forward, joined, and forming a narrow free fold; 

 anus about three-fourths the way from base of pelvics to anal origin; 

 a vertical line through dorsal origin passes about midway between 

 pelvic insertion and anal origin; pelvics do not reach past anus; caudal 

 fin truncate; other fins rounded; eye small, witliout free margin, more 

 or less embedded; maxillary barbel reaching to rear of base of pectoral 

 fin; lower maxiUary barbel reaching to insertion of pectorals or 

 a trifle be3''ond; nasal barbel reaching a little past tip of opercle; 

 teeth villiform, pointed, in a band on premaxillaries and at front of 

 dentaries. 



Color consisting of a dark band along midsides, another along upper 

 sides from nostrils through eye past base of dorsal fin and a third 

 along middorsal line anteriorly fading before dorsal fin, these three 

 black bands separated b}- pale bands; no spots anywhere; belly plain, 

 light grayish yellow. The band along midsides very intense in the 

 young but more or less diffuse in adults; all fins grayish. 



Remarks. — This species differs from all other forms with a truncate

 three blackish bands, two on the side and one along middorsal line 

 anteriorly.
