156 ' ENDEAVOUR " SCIENTIFIC RESULTS. 



which increase in size backwards ; they do not extend onto 

 the bases of any of the fins. Lateral line curved in its extreme 

 anterior portion, thence running obliquely to the middle of 

 the caudal peduncle. There are forty-two to forty-three, or 

 thirty rows of scales below the lateral line, according to the 

 direction in which they are counted. 



Dorsal fin commencing on the neck a little behind the 

 verticle of the posterior orbital margin ; the third and fourth 

 spines are the longest, the others decreasing in length to the 

 twelfth ; the thirteenth is nearly twice as long as the pre- 

 ceding one, and about half as long as the second ray. Margin 

 of the soft dorsal rounded. Second anal spine longest, very 

 strong and sulcate, and more than three-fourths as long as the 

 rays. Pectoral almost reaching the verticle of the vent ; six 

 or seven of its lower rays are thickened, and either simple or 

 more or less branched according to the age of the specimen ; 

 the fourteenth to sixteenth rays are longer than those above 

 them, and their tips project beyond the margin of the fin. 

 Ventrals rather elongated, the second ray reaching almost to, 

 or a little beyond die vent. Caudal rounded, though the 

 lower rays are longer than the upper ones. 



Colour. Light, brown above in formalin, whitish below. 

 The body is crossed by two irregular darker bars, and bears 

 many smaller spots and lines. Head similar to the body. 

 Upper surface of eye with rounded whitish spots on a darker 

 ground colour. Dorsal blotched with lighter and darker 

 markings, the tips of the membrane behind the spines white. 

 Second dorsal with a large black ocellus covering the basal 

 portions of the posterior rays ; upper half of the fin grey, with 

 a narrow white margin. Basal half of anal whitish, the outer 

 portion dark grey. Pectoral light-coloured, with fine grey 

 lines crossing the rays. Distal portion of ventrals greyish. 

 Caudal with a dusky band crossing its distal half, with or 

 without dark spots on the basal portion. 



Eighteen specimens, 180-255 mm. long, are preserved, 

 which are referred to by Ogilby. His description was based 

 on three specimens trawled off Cape Moreton, where many 

 others were obtained, but none from that locality were for- 

 warded to the Australian Museum. The foregoing description 

 chiefly refers to a specimen 232 mm. long from three miles 

 south-east of Double Island Lighthouse, which is the example 

 figured. 



Locs. Twenty-five miles south-east of Double Island Point, 

 Queensland, 33 fathoms ; 28th June, 1910. 



Three miles south-east of Double Island Lighthouse, 

 Queensland, 32 fathoms ; 16th July, 1910. 

 Wide Bay, Queensland.
