208 "ENDEAVOUR" SCIENTIFIC RESULTS. 



First dorsal spine inserted in advance of the pectoral 

 fins; it is longer than the others and is produced into a 

 short filament which scarcely reaches backward to the 

 first dorsal ray. Anterior ray longer than the spine, but 

 shorter than the last, which reaches backward beyond 

 the hypural joint ; all the rays are simple except the last, 

 which is divided to its base, and each branch is bifurcate. 

 Anal of similar form to the dorsal but lower, and com- 

 mencing and terminating well behind it. Upper margin 

 of pectoral excised, the median rays longest and reaching 

 backward to the vertical of the second anal ray; all but 

 the upper rays are bifurcate. Ventral rays coarsely 

 branched, not quite reaching the origin of the anal fin. 

 Caudal fin elongate, much longer than the head; all but 

 its outer rays are bifurcate. 



Colour -marking. General colour greyish brown in 

 formalin, the upper surface closely covered with small 

 and indistinct lighter spots with dark margins. The 

 sides of the head bear a number of large brown ocelli 

 with light margins; these are most conspicuous upon 

 the lateral angle between the mouth and the preopercular 

 spine, but are also present upon the preorbital region 

 and operculum. A large, black, white-edged spot on the 

 operculum beneath the preopercular spine. Several in- 

 definite dark blotches on each side of the body below the 

 lateral line. First dorsal grey with a large incomplete 

 dark ring on the third spine, and some indefinite darker 

 markings. Second dorsal with numerous blackish dots 

 irregularly disposed between the rays. Anal dusky, 

 lighter basally. Caudal with black dots similar to those 

 of the second dorsal, and a grey stripe between the lower 

 rays. Ventral with a dark border. 



Described and figured from a single male example, 

 218 mm. long. 



Of the Australian species, this is nearest G. 

 calcaratus, from which it is readily distinguishable by its 

 colour-marking, longer tail, and in having the first dorsal 

 spine distinctly longer than the second. 



Locality. This specimen is unfortunately without 

 data. It is registered in association with some Queens- 

 land fishes, but cannot be definitely recorded from that 

 State.
