 over the posterior dorsal rays.

Teeth notched ; the cleft of the mouth does not extend to the 

 vertical from the orbit ; the praeorbital, above the angle of the mouth, 

 is nearly as broad as the diameter of the eye. The five vertical 

 bands are less distinct than in G. saxatilis. (M. Sf T.)

The height of the bodj' is somewhat more than one-half of the 

 total length (without caudal) ; the width of the interorbital space, 

 which is slightly convex, is more than that of the orbit. The breadth 

 of the infraorbital ring below the middle of the eye is two-thirds of 

 the greatest breadth of the praeorbital. (Pneoperctdar margins not 

 serrated.) Incisors moderately broad, deeply notched. Caudal fin 

 slightly emarginate. Body dark-greenish-olive, with five rather 

 indistinct blackish cross-bands : the first very obscure, in front of 

 the dorsal fin ; the second from the third to fifth spines ; the third 

 from the seventh to ninth towards the vent ; the fourth from the 

 last dorsal spines towards the anterior soft anal rays ; the fifth from 

 below the posterior half of the soft dorsal ; pectoral with a tapeiing 

 black transverse line at the base.
