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
