ADDITIONS TO THE FISH FAUNA OF LORD HOWE ISLAND — WAITE. 201 



Chironemus marmoratus, GUnther. 



The Kelp-fish is common on the coast of New South Wales, 

 and is, I learned from the Lord Howe Islanders, sometimes caught 

 off the coral reefs. We have an example in the Museum, obtained 

 by Mr. Icely, and this is recorded by Ogilby,* but for reasons 

 applied to Trachinotus, is also noticed here. 



Amphiprion latezonatus, sp. nov. 



(Plate xxxiv.) 



D. xi. 15. A. ii. 13. V. i. 5. P. 17. 0. 15 + 2. L. lat. 38. 

 L. tr. 6/18. 



Length of head, to which the caudal tin is equal, 3-6, height of 

 body 2'0 in the length (caudal excluded). Diameter of eye 2*8, 

 length of snout 3'0 in the length of the head. Interocular space 

 very slightly convex, a little raoi'e than the diameter of the eye. 

 Twelve gill rakers on the lower limb of the first arch, the centre 

 ones narrow and rather long. Teeth conical in a single series in 

 each jaw. Preopercle denticulated, its angle in advance of the 

 centre of the eye. Opercle formed of two lobes strongly spinose. 

 Dorsal fin without notch, its first spine placed above the margin 

 of the opercle, its length less than the diameter of the eye, the 

 eighth spine is the longest, and is one-tenth longer than the eye ; 

 the central rays are the longest, twice the diameter of the eye. 

 The anal spines are short but stout, and the longest rays are more 

 posterior than the corresponding ones of the dorsal. 



The pectoral and ventral are long and equal, one-seventh 

 longer than the head, the latter extending to the base of the 

 second anal spine. The caudal is forked, the upper rays the longer, 

 the length of the pedicel equals its height, which is one half the 

 length of the head. 



Scales. — The scales are large, with entire margins, the lateral 

 line, which terminates in advance of the dorsal rays is composed 

 of thirty eight scales, this is also the number of the series between 

 the opercle and the caudal. 



Colours. — General colour dark brown with three light cross 

 bands, the first is as wide as the diameter of the eye, the posterior 

 margin of which it embraces ; it passes from the occiput, in front 

 of the dorsal spines downwards and forwards, and crosses the 

 preopercle, opercle, and sub-opercle: its posterior margin is convex 

 and on the dorsal profile this margin is deflected forwards. The 

 second band arises in the space between the eighth spine and the 

 second ray, its anterior edge takes a forward sweep gaining the 

 ventral profile just behind the ventral fins, its hinder edge is
