The snout forms half the length of the head ; its crest is com- 

 posed of about ten iiTcgular teeth, and further back are two others. 

 The double frontal crest is well dentated. The superior orbital 

 border has five or six teeth. The ridge under the orbit is unarmed, 

 but on the side of the snout it is well serrated. The chin is prominent 

 but unarmed ; and some distance behind, in the middle, is a sHght 

 swelUng. The longest superior pectoral rays are about equal to the 

 length of the oj^erculum. The caudal is as long as the snout. The 

 colour is an almost uniform yellowish brown, but with a black streak 

 from the snout to the upper axilla of the pectoral fin. {Gill.)

AU the angles of the body serrated. Measured from the fore 

 border of the orbit, the snout is as long as the distance between the 

 hinder edge of the orbit and the extremity of the gill-cover. Next 

 the nostril there are three coalescent spines, and there are six stand- 

 ing close together on the end of the snout. A row of short spines 

 runs from the under edge of the orbit ; and a row extends from be- 

 hind the orbit to above the tubular nostril. The occiput is finely
