head ; the rays are similar to, but lower than those of the dorsal. 

 The ventral spine is as long as, but weaker than the second anal ; 

 the rays reach to the base of this spine; the pectoral is of the 

 same length. The caudal is rounded and is a trifle shorter than 

 the head. The lateral line forms an even curve from the opercle 

 to the end of the dorsal, where it terminates at the juncture of 

 the fin with the caudal peduncle. The scales of the upper part 

 of the body do not form an angle with those of the lower part. 



Colours. — The ground colour is yellowish in spirits, vertically 

 and entirely crossed by three broad black bands ; the first (the 

 ocular) embraces the base of the first dorsal spine, passes through 

 the eye, and obliquely backwards on to the chest. The second is 

 twice the breadth of the first ; it arises from the 4-8 spines, and 

 with a forward sweep attains the lower profile between the ventral 

 and anal tins, being narrower below than above. The third band 

 is equal in breadth to the second, and is of uniform width ; it 

 commences on the tenth spine, and leaving a band of the ground 

 colour, an eye-diameter wide, reaches the base of the third anal 

 spine. The caudal has a faint terminal band, convex anteriorly ; 

 the paired fins are without markings. 



Length of specimen 97 mm. 



This CluHtodon was obtained by Mr, T. R. Icely, formerly Visiting 

 Magistrate, in August, 1894. I was unable to find it for inclusion 

 in my first "Additions to tlie Fish-fauna of Lord Howe Island,"^" 

 but having since recovered it, furnish the above description for the 

 present contribution. 



Other three Chsetodontoids have been recorded from the island, 

 these are: — Chcetodon strigatus, Guv. & Val. ; C. aphrodite, Ogil. ; 

 and Chelmo truncatus, Kner. 



MoNACANTHUS iiowENSis, Ogilby. 



(Plate viii.) 



To the present time this species was known from a single 

 specimen, the type. I am pleased, therefore, to be in a position 

 to record a second occurrence. The original example, which I 

 now have before me, measures 200 mm. in length; the recent 

 specimen is smaller, being 177 mm in length. Its colour is well 

 preserved in formaline ; this enables me to correct and supplement 

 the original description, and to give a reliable figure of the species. 



The general colour of the body is bluish-grey, with rather small 

 white spots disposed regularly all over, the upper surface of the 

 snout excepted (these spots are probably pale blue in life). The 

 lower half of the body, behind the pectoral fin, has black spots 

 also, equal in size to the white ones, but more irregularly spaced.
