102 MEMOIRS OF THE QUEENSLAND MUSEUM. 



peduncle; ventral contour gently rounded from the lip to the ventral, thence 

 linear and feebly declivous to the anal, the base of which is evenly convex; least 

 depth of caudal peduncle 7-1 in the length of the body. Width of head 14 in 

 its length, which is 1-15 in its depth and 3-66 in the body-length. Diameter of 

 eye one sixth more than the length of the snout, which is 2-85 in that of the head ; 

 interorbital region convex but not elevated, as wide as the snout is long. Jaws 

 equal, maxillary extending to below the anterior border of the eye. Preorbital 

 with 3 or 4 strong teeth, its width 1-9 in the eye-diameter. Hinder limb of 

 preoperele inclined backwards and feebly serrated ; a strong retrorse tooth on 

 the lower limb close to the spine, which is short, 2-85 in the length of the head, 

 and extends to below the border of the opercle. 



Scales as in H. bicolor, but without squamulas, in 46 series above the 

 lateral line, and in 6/1/23 between the spinous dorsal and the vent. Lateral 

 line incomplete, terminating at the base of the 11th dorsal ray. 



Dorsal fin originating above the base of the pectoral, with xiv 15 rays, 

 the soft portion 1-75 in the length of the spinous; spines graduated, the first 

 moderately developed, 2-6 in the last, which is 1-2 in the soft fin and 4-55 in 

 the body-length ; soft dorsal with obtusely angular outline, the posteromedian 

 rays the longest, extending to beyond the level of the middle of the caudal; 

 procumbent spine protruding. Caudal tin rounded, the middle rays longer than 

 the outer and 3-8 in the length of the body. Anal with iii 17 rays, originating 

 below the 12th dorsal spine ; spines much stronger than those of the dorsal, the 

 1st long, 1-45 in the last, which is 1-15 in the longest ray and rather less than 

 the last dorsal spine; soft anal similar to but shorter, lower, and less pointed 

 than the soft dorsal, so that the hinder border is obliquely linear. Pectoral with 

 16 rays, its length 3-5 in that of the body; 4th ray longest, extending to below 

 the 7th dorsal spine. Ventral much longer than the pectoral, the spine half as 

 long as the outer ray, which is much produced. 2-6 in the body-length, and 

 reaches to the base of the 1st anal ray.

 Uniform pearl gray, the head and shoulders with a dirty yellow tint. 



(2) Of fresh specimen fide Jordan and Scale • — "Clear deep yellow, citron- 

 yellow below ; fins all the same ; dorsal, anal, and caudal with very narrow bright 

 blue edge ; a deep blue ring around the orange eye ; a deep violet-blue on opercle 

 with an orange edge behind ; preopercular spines and two bars across the chin 

 slaty blue; two slaty spots on breast; upper lip slaty."
