 and palatines ; process of premaxillary prominent, extend- 

 ing between and above nasal spines ; preopercular process 

 well developed, long, near its tip a very small second 

 spine is developed, making the process befurcate, 3 or 4 

 short spines below on edge of preopercle ; opercle end-

 margin ; a few shorter ones on nape ; mucous pores 

 around mandible, large; opercle, upper part of preoper-

Lateral line with a row of rough plates ; upper half of 

 body completely covered with scales, their anterior edge

 half of body naked. 



Dorsal spines slender, those in the middle highest, the 

 fin without a notch, the longest spines reaching to front 

 of soft dorsal where fin is depressed, well separated from 

 soft dorsal; first dorsal ray inserted over first anal ray, 

 the fin longer and higher than anal; pectorals somewhat 

 pointed posteriorly, reaching just past the space between 

 dorsals; ventrals inserted behind the base of pectorals a 

 distance equal to the length of snout, their tips reaching 

 to the front of the anal ; caudal slender, rounded behind. 



Color olive gray, belly dusky; back with dark cross 

 shades, irregular in number and size, below lateral line 

 light with small wavy bars running across to within a
