Back and belly covered with small two-rooted spines, the snout 

 and tail being naked ; the sides are generally crossed by two broad 

 stripes of spines in front and behind the pectoral fin. The length of 

 the head is nearly equal to its distance from the dorsal fin. Caudal 

 fin truncate. The upper teeth not much smaller than the lower. 

 The osseous interorbital space is broad in adult examples (from 

 about 6 inches in length), its width being equal to the length of the 

 snout. Upper part of the head and middle of the back brown, with 

 round white spots ; on the sides the brown colour descends in irre- 

 gular transverse bands {ohJonrjus). Frequently the distribution of 

 the colours on the sides is the same as on the middle of the back ; 

 that is, all the upper half of the fish is brown, with round white 

 spots {alboplumbeus). Frequently a large round black spot above the 

 end of the pectoral fin.
