 interorbital space about two-thirds diameter of eye. Two nearly parallel 

 high sharp ridges run from first dorsal spine to snout. A ridg(> around 

 anterior margin of eye runs backward to beneath base of third dorsal 

 spine; it has a depression above middle of ej^e and another above pos- 

 terior part of eye. Superior margin of eye with a ridge which is

 ridge extends backward above gill-opening nearly to tip of opercular 

 flap. Suborbital stay with a sharp, smooth ridge extending back and 

 joining at right angles a ridge that follows around margin of pre-
