praeoi'bital, which widens above, and is furnished by strong spinous 

 teeth beneath, dii-ected backwards ; this serrature becomes finer on 

 the suborbital arch. The upper maxillary is styliform, and forms 

 posteriorly a triangular plate ; it does not appear to reach the middle 

 of the eye. The eye is jjlaced high up the side, and does not interfere 

 with the upper outline of the head ; its diameter is nearly one-fourth 

 of the length of the head. The operculum has a somewhat rounded 

 posterior angle, without distinct point ; the praeoperciilum is finely 

 serrated along the posterior limb, and armed with a triangular and 

 keeled spine of moderate size at the angle ; the lower limb has no 

 denticulation whatever. 



The greatest depth of the hodii is between the origins of the 

 second dorsal fin and the anal, the profile rising steeply from the 

 occiput to the highest point ; the tail (without caudal), behind the 

 end of the doreal, is as high as long. 



The third spine of the dorsal fin is veiy long, one-sixth of the 

 total length ; the first is small ; the second shorter than one-half of 

 the thii'd ; the fourth, fifth and sixth rapidly decrease in length ; the 

 seventh and eighth are short, and inserted between both dorsals. 

 The fii'st spine of the second dorsal is a little longer, one-half of the 

 height of the fin. The rays are nearly equal in length, much shorter 

 than the spinous part, and form a rounded fin. Caudal rounded, 

 with eighteen rays. The anal fin resembles in shape the soft dorsal, 

 but its base is longer, and the longest ray is somewhat higher. The 

 spines are of moderate strength ; the second is rather longer than 

 the thii'd, and two-tliirds the length of the longest ray. The pec- 

 toral and ventral fins are nearly equal in length ; the latter do not 

 reach to the vent ; their spine equals the fifth of the dorsal.
