Thia species varies in a remarkable mauucr iu the extent of the 

 spines over the body : sometimes they project ranch out of the skin, 

 and cover nearly the entii'c body like bristles ; sometime.s tbey are 

 much less numerous, and nearly entirely hidden in the skin, the 

 greater part of which appears to be smooth. Snout rather short aiul 

 obtuse, two-fifths of the length of the head. The interorbital s])ace 

 appears flat and broad externally ; but the width of the osseous por- 

 tion is much less than the length of the snout, and about twice the 

 diameter of the 6ye. Length of the caudal fin equal to its distance 

 from the dorsal. Uniform darlv brown above and whitish below ; a 

 feM' scattered round black spots on the side ; vent black. Pins and 

 base of the fins not spotted. Caudal fin sometimes with a white, 

 never with a black, margin. Mouth black.
