 The length of the head is 3| in the total, and its width between 

 the prseopercular spines If in its length; the space between the 

 eyes is very concave, and half as wide as the vertical diameter of 

 the orbit. The superciliary ridge, a ridge from the eye to the 

 occiput, another from the eye to the scapula, and a fourth from the 

 praeorbital to the angle of the praeoperculum, -armed with spines 

 directed backwards. Two prseopercular spines, the upper of which 

 is very long, and would reach into the orbit if laid forwards. The 

 length of the second dorsal spine is 2^ in that of the head. The an- 

 terior portion of the lateral line spiny.

The length of the head is 3| in the total, and its width between the 

 praeopercular spines 1|- in its length ; the space between the eyes is 

 concave, and 2| in the length of the snout, or two-thirds of the vertical 

 diameter of the eye. The superciliary ridge, a ridge from the eye to 

 the occiput, another from the eye to the scapula, and a fourth from 

 the prgeorbital to the angle of the praeoperciilum, armed with small 

 spines directed backwards. Two praeopercular spines, the upper of 

 which is equal in length to one-half its distance from the orbit ; the 

 lower short. The length of the second dorsal spine is 21 in that of 

 the head. Lateral line spiny, with about fifty-five spines. The first 

 dorsal blackish, the other vertical fins spotted with brown.
