 fins situated much nearer to the anal than to the pectoral pair, 

 arising immediately in advance of the origin of the dorsal. Dorsal 

 fin at least as high as long, larger than the anal. Scales of 

 moderate size, marked in front with a few irregular, short, trans- 

 verse grooves, in the hinder half with sparse elongated pittings, 

 and the hinder margin denticulated except in those towards the
