Teeth distinctly bicuspid, the cusps being subequal and slightly 

 tinged with brown ; from twenty-eight to thirty-one on each side 

 of the outer series of the upper jaw. Cheeks naked or only with 

 a few extremely thin scales. In a specimen nearly 5 inches long 

 the diameter of the eye is nearly equal to the depth of the soft 

 part of the cheek and a little less than the width of the prceorbital 

 and of the interorbital space, which is flat. The angle formed by 

 the prajopercular limbs is a right one. The height of the body is 

 somewhat less than the length of the head and one third of the 

 total (without caudal). The longest dorsal spine is the last and is 

 two fifths of the length of the head. Pectoral fin extending to, 

 or nearly to, the origin of the anal. Caudal scaleless. Scales rough, 

 some with the margins ciliated. Body light greenish, with more 

 or less conspicuous incomplete brownish cross-bands on the upper 

 part of the body. The largest specimen has the cheek and snout 

 ornamented with irregular deep brown spots ; the soft dorsal and 

 the caudal fin with scattered ocelli ; a milky-white spot between 

 the last two anal rays.
