ADDITIONS TO THE FISH FAUNA OF LORD HOWE ISLAND — WAITE. 205 



3"1, of preopercular spine 2'0 in the length of the head ; the inter- 

 orbital space is convex, one-fourth more than the diameter of the 

 eye. Gill-rakers narrow, of moderate length, eleven on the lower 

 limb of the first arch. The teeth are cardiform, arranged in a 

 narrow band in each jaw, each with a tricuspid apex. The body 

 is rather elongate, the anterior profile slightly rounded and tumid 

 above the snout ; jaws equal, only slightly protractile, the maxilla 

 is shorter than the diameter of the eye ; preorbital produced into 

 a spine directed horizontally forwards and its lower angle into 

 three smaller spines directed forwards and downwards, followed 

 by four small points. Preopercle inclined forwards, its hinder limb 

 strongly serrated, its lower with four strong denticles. The spine 

 is gently curved and received into a shallow groove in front of 

 the pectoral, its point reaches the vertical from the margin of the 

 opercle, a membrane invests its inner surface. The opercle and 

 subopercle finely denticulated the points rather distant. The first 

 dorsal spine is situated above the opercular margin, and its length 

 equals the diameter of the eye, the others gently increase in length 

 to the fifteenth which is the longest, and last, exactly twice the 

 length of the first, the central rays are produced but not filamen- 

 tous, the tenth which is the longest, is three-fourths the length of 

 the head. 



The first anal spine arises beneath the eleventh dorsal, the 

 third is the longest, 1"6 in the length of the head ; all are stouter 

 than the dorsals. The rays are similar in character and extent 

 to those of the dorsal and it is also the tenth which forms the 

 summit of the fin which terminates evenly with the dorsal. The 

 pectoral is equal to the head in length, as is also the ventral but 

 its first ray is produced, the filament reaching to the first anal spine. 

 Caudal lunate its upper and lower rays produced into filaments, 

 the height of the pedicel is half the length of the head. 



Scales. — The scales of the body are large, the exposed portions 

 angular in shape, strongly ciliated ; removed from the body each 

 scale is subcircular in outline a little higher than long; the scales 

 on the fins are very small. The lateral line rises to below the 

 fifth dorsal spine whence it follows the curvature of the back to 

 near the termination of the rays, it then bends abruptly down- 

 wards and runs horizontally along the caudal pedicel. 



Colours. — After long immersion in spirits the general colour 

 is yellowish, tending to brownish on the head and dorsal surface, 

 the fins are also yellowish and immaculate, with the exceptions 

 below mentioned. The upper half of the body is crossed with 

 eight or nine sub-vertical lines of dark brown, they have a slight 

 posterior inclination and anteriorly do not cross the mid line of 

 the body, they descend lower behind but do not even there reach 

 the ventral profile ; the first distinct line arises from the base 

 of the third dorsal spine but there is a faint trace of one in
