rough margins, and their exposed surfaces coarsely striate. 

 They form a low sheath at the base of the spinous dorsal, and 

 •cover the membranes of the soft dorsal and. anal ; they also 

 extend over the basal half of the caudal, and portion of the 

 pectoral. Lateral line scarcely arched, formed of simple 

 tubercles, which extend on to the caudal base. 



Fin?. — Dorsal commencing well behind the vertical of the 

 ventral. Its spines are slender, and increase rapidly in length 

 to the fifth, after which they become slightly shorter to the 

 last ; the dorsal rays decrease regularly in length backward. 

 Anal commencing beneath the third dorsal ray ; its spines 

 increase in length backward, the third being two-thirds as 

 long as the first ray; soft anal similar in form to the dorsal. 

 Caudal deeply forked. Fifth upper pectoral ray longest. 

 Ventrals not nearly reaching the vent. 



Colour. — After long preservation in formaline, the 

 general colour is brown above, lighter below. A light-coloured 

 area commences above the shoulder and extends backward to 

 the caudal fin, and covers the greater part of the back above 

 the lateral line. It is defined anteriorly and below by a 

 dark-bluish area, which commences behind the eye. Dorsal 

 and anal fins dusky, the latter with a light edge. An ill- 

 defined dark spot at the base of the pectoral. 



Described from five specimens, 134-154 mm. long measured 

 from the snout to the end of the middle caudal rays. They 

 differ from L. argent eiventr/s, Peters, in having smaller scales 

 and ten instead of eleven dorsal spines. 



Loc— Four of the specimens were collected for the Aus- 

 tralian Museum by Mrs. T. Nichols at Lord Howe Island. 

 The other was secured at Norfolk Island by Mr. George E. 

 Nobbs.
