ADDITIONS TO THE FISH FAUNA OF LOUD HOWE ISLAND WAITE. 203 
canine teeth are developed equally with the upper ones ; both 
pairs are curved and divergent, the lower biting between the 
upper ones which are rather widely spaced. The second dorsal 
spine is united to the third, as shown in my figure. 
Ciielmo truncatus, Kner. 
A beach-dried example was obtained by Mrs. T. Nicholls, and 
forwarded to us in August last; and in the “old collection” there 
is a specimen in spirits, also from the island. 
Holacanthus tibicen, Cuvier and Valenciennes . 
All the specimens received from the island possess but three 
anal spines, as in normal examples, and have fourteen dorsal 
spines. This record is an addition to the Australian fauna, and 
we are indebted to Mr. Icely for the series obtained. 
Holacanthus conspicillatus, sp. nov. 
(Plate xxxv.) 
D. i. + xiii. 18. A. iii. 18. 7. 1*5. P. 17. C. 15 + 2. 
Length of head 4*4, of caudal fin 5*4, height of body 2*0, in the 
length (caudal excluded). Diameter of eye 3*7, length of snout 
3*2, of the preopercular spine 2*0 in the length of the head. The 
interorbital space is convex, one-fourth more than the diameter of 
the eye. Thirteen gill-rakers on the lower limb of the first arch, 
all small, triangular in shape. The teeth are cardiform, and are 
arranged in a dense band across the front in each jaw. The 
individual tooth is brown, with a lighter apex, broader than the 
base ; it is tricuspid, the centre cusp long and acute, the lateral 
ones small and slightly deflected outwards. Body somewhat elon- 
gate, anterior profile slightly concave above the snout and in front 
of the orbits, snout protruding, protractile, the lower jaw much 
the longer ; maxilla nearly vertical, equal in length to the diameter 
of the eye; margin of preopercle inclined forwards, below feebly 
serrated ; spine gently curved, not channeled, reaching to beneath 
the bony margin of the opercle, a membrane closely invests its 
whole inner surface ; the spine is received into a shallow groove 
in front of the pectoral. The angle of the opercle is slightly pro- 
duced, but there is no spine. There is a short recumbent spine 
immediately in advance of the first erect dorsal spine which 
arises in advance of the vertical from the opercular border ; the 
eleventh spine is the longest 1*55 in the length of the head and 
is slightly shorter than the longest rays. The first anal spine 
arises beneath the eleventh dorsal, to which the third anal is 
equal, the soft dorsal and anal are not produced but are rounded 
posteriorly, both terminate in the same vertical line, but the anal 
rays extend somewhat further back, nearly to the base of the 
caudal. Pectoral longer than the ventral which latter is contained
