Height of body 14 times in the length, and length of head 4 

 times in the total length, and 3 J times its height and 1 J times its 

 breadth , Resembles P. insidiator, but with the eye much larger, 

 forehead and praeorbital narrower, and parallel supraorbital crests, 

 which in P. insidiator converge backwards. The point of the 

 tongue is in this species spatulate and prominent, in the other 

 species truncate. It differs also in the number of the dorsal rays, 

 being 12 in this as against 13 in P. insidiator. The lower 

 prseopercular spine is a little longer than the upper. The colour 

 resembles that of P. insidiator, the fins have a rather greener hue 

 and not brown-spotted.
