Minute spines cover the back from the intcrorbital space to near 

 the dorsal fin, and the abdomen from the throat to the vent, the 

 dorsal and abdominal spiny patches being connected by a transverse 

 stripe of spines behind the pectoral fin, the snout, sides, and tail 

 being naked. Snout rather jproclucecl, the eye beincf nearer to the root 

 of the pectoral Jin than to the end of the snout. Distance of the nos- 

 tril from the eye not much less than the diameter of the latter, 

 Intcrorbital space generally concave (fiat in examples from Bahia) ; 

 the diameter of the eye is two-thirds of the width between the bony 

 orbital edges. Length of the caudal equal to its distance from the 

 dorsal fin. Sides sometimes with small tentacles. Brownish black 

 above, with whitish lines, the anterior of which are transverse (on the 

 head and nape) ; one or two concentric circles in front of the dorsal 

 fin. Sides yellowish, with small round brown spots. Abdomen and 

 fins immaculate. The lines on the back are more regular in young 

 than in old examples, which sometimes have the back and sides 

 irregularly marbled and spotted with brown or black.
