extending into the scaly shoulder to below the procumbenl spine. Lateral line 

 strongly arched to below the »>th dorsal spine, the length of the curved section 

 2«6 in that of the straight, which is armed throughout with 36 strongly keeled 

 spinigerous scutes, the widesl of which are below the last third of the soft dorsal 

 and 1-33 in the eye-diameter: some of the spines on the peduncle exceptionally 

 strong, upright, and recurved. 



Dorsal fin with viii, i 18 rays: spinous dorsal well developed, originating 

 above the base of the pectoral; procumbent spine strong and exposed; spines 

 flexible, the 3rd longest. 2-75 in the length of the head, the last small and isolated. 

 Soft dorsal originating about one eighth nearer to the root of the caudal than 

 to the tip of the snout, the anterior rays produced as a falciform lobe, its length 

 4-7 in that of the body and extending when depressed to the 10th ray; last ray 

 somewhat produced. Caudal tin deeply forked, the upper lobe the longer. 3-55 

 in the length of the body. Anal fin with ii. i 16 rays, originating below the 7th 

 dorsal ray; free spines well developed, the 2nd the longer, 1-95 in the eye-diameter 

 and 4-25 in the 1st ray, which is 1-75 in the length of the head and extends when 

 depressed to the 10th ray. Pectoral with 19 rays, its length 2-85 in that of the 

 body and about one twelfth more than that of the head, the 5th ray longest, 

 extending to above the 5th anal ray. Ventral moderate, its length 2-35 in that 

 of the pectoral and 6-7 in that of the body, the outer ray longest, extending to 

 the vent. 



Gill-rakers stout and rather long, 6+20 on the anterior arch, the longest 

 about two fifths more than the gill-fringes and 5-65 in the length of the head. 

 Vent situated one fourth nearer to the anal than to the origin of the ventral. 



Upper surface pale olive green with or without blue spots. 10 sides silvery ; 

 abdomen, breast, and lower surface of head milk-white; a well marked black 

 axillary spot, extending downwards to cover the posterior half of the pectoral- 

 base; a large diffused dark spot on the upper half of the opercle. Fins pale

 mouth.) 



Described from a single specimen, 235 millim. in length, forwarded from 

 Townsville by Mr. P. H. Taylor. Entomologist to the Institute of Tropical 

 Medicine, to whom we hereby return our best thanks. 



Historical: — Our earliest knowledge of this species was supplied by the 

 naturalists of the " Chevert," who collected two specimens, measuring 207 and 



'"On our specimen all the body above the level of the straight part of the lateral line 

 is closely blue-spotted. 



20 McCulloch (in lit.) says— "My smallest specimen, 123 millim., has five broad, dark 

 cross-bars descending from the back to the middle of the sides."
