<30 MEMOIRS OF THE QUEENSLAND MUSEUM. 



3-75 in the length of the head and 1-33 in that of the snout; interorbital region 

 convex, its width 1-15 in the eye-diameter. Lower jaw projecting; maxillary 

 strongly dilated, not quite extending to the vertical from the anterior border of 

 the eye, its length 2-85 to 3 in that of the head, the width of its concave distal 

 extremity one fourth to two fifths more than its distance from the eye and 

 2-33 to 2.4 in the eye-diameter. Angle of preopercle feebly crenulate. 



Teeth in the jaws minute, forming a villiform patch anteriorly but 

 reduced to a single series laterally ; a diamond-shaped patch of larger teeth on 

 the head of the vomer, the lateral angles of which are somewhat produced, and 

 which is followed on the shaft by a single series of decrescent teeth; palatines 

 and tongue each with a narrow band of villiform teeth. 



Cheeks, postorbital and parietal regions, and upper part of opercle wholly, 

 occiput and interorbital region partly scaly, the two latter with three naked 

 bands, a median extending from between the nostrils to the nape, and a lateral 

 pair each extending from behind a nostril to the occiput, where it bifurcates, 

 the outer branch bent downwards across the parietal to finally merge in the 

 lateral line, the inner, which is again divided, uniting with the median band 

 where it enters the occiput and again at its tip ; each band and its branches 

 carries a pinnated mucous canal. Lateral line forming a long shallow curve to 

 below the 11th or 12th dorsal ray, the curved section about one fourth longer 

 than the straight, which is armed with 32 or 33 moderately strong keeled scutes, 

 the widest about 1-9 in the eye-diameter. 



Dorsal fin Math viii, i 31 i rays, originating above the basal fourth of the 

 oppressed pectoral; procumbent spine small, concealed; spinous dorsal high, 

 the spines flexible, the 3rd longest, half the length of the head. Soft dorsal 

 originating a little nearer to the root of the caudal than to the tip of the snout, 

 the anterior seven rays graduated and but little produced, the 1st ray 1-3 to 14 

 in the longest spine and 8-9 to 9-5 in the body-length ; pinnula much longer than 

 the last connected ray and split to its base. Caudal fin small and widely forked, 

 the lobes obtusely pointed, its length 5-25 in that of the body. Anal with ii, 

 i 25 to 27 rays, originating below the 6th or 7th dorsal ray ; free spines strong, 

 1st the longer, 1-67 to 2-1 in the eye-diameter and 2 to 2-2 in the longest ray, 

 which is 2-8 to 3-1 in the length of the head; pinnula similar to that of the 

 dorsal. Pectoral with 21 to 23 rays, its length 3-8 to 4-1 in that of the body ; 

 5th ray longest, extending to above or slightly beyond the vent. Ventral 

 moderate, 1-9 to 2 in the length of the pectoral and 2-2 to 2-3 in that of the head ; 

 2nd ray longest, reaching midway to the base of the 1st free spine. 



Gill-rakers slender and moderately long, 5 —J- 31 or 32 on the anterior 

 arch, the longest 1-35 in the gill-fringes and 6-75 to 7 in the length of the head. 

 Vent close to the free anal spines, its distance from the anal 3-1 to 3-5 in that 

 from the origin of the ventral.
