]7ti MEMOIRS OF THE QUEENSLAND MUSEUM. 



First dorsal spine inserted over the anterior third of the eye; the first 

 four spines are widely separated but connected by membrane, and the third is 

 but little shorter than the last though distinctly longer than those immediately 

 before and after it. The first dorsal ray is as long as the last spine, and is 

 unbranched; the four following rays are bifurcate, while the last is simple and 

 joined by membrane to the caudal peduncle. Anal fin originating below the 

 thirteenth dorsal spine; its spines increase in length backward, and the third 

 is about as long as the last dorsal spine but distinctly shorter than the succeeding 

 rays. Soft portion of the anal rounded; its two outer rays are simple and the 

 others bifurcate, and the last is united with the caudal peduncle by membrane. 

 Pectoral rounded, its middle rays longest and reaching to the vertical of the anal 

 origin ; five of the upper rays are bifurcate, and the eight lower ones are simple 

 and thickened. Ventrals inserted behind the bases of the pectorals, each with 

 a strong spine and four weak rays, of which three are bifurcate; the longest 

 does not nearly reach the vent. Caudal rounded, with eleven branched rays. 



Colour. — Light brown changing to whitish below, with a paler stripe along 

 the back at the base of the dorsal spines; some very indefinite darker cross-bands 

 are apparent on the back which become more distinct on the caudal peduncle. 

 Some irregularly placed dark -brown spots with lighter edges are scattered over 

 the neck and back above the lateral line, and several lighter ones occur on the 

 scapular region. Upper surface and sides of head closely covered with rounded 

 brown spots with lighter edges, some larger ones of which are situated above the 

 operculum and one at the postero-inferior angle of the eye. Lips crossed by 

 j)ale-brown narrow bands. Spinous dorsal irregularly marbled with brown, and 

 crossed bj^ oblicpie darker-brown bands which ])ecome narrower and more 

 numerous on the soft portion, and coalesce so as to leave only a series of white 

 spots on the rays. Anal with a few light-brown cross-bars on the rays. Pectoral 

 and caudal fins barred with dark brown. Ventrals whitish. 



Described and figured from the holotype of the species, which is 75 mm. 

 Icmg from the snout to the end of the tail. It differs in several small details 

 from Ogilby's description owing to the fact that the latter was written on board 

 the "Endeavour," where the conditions rendered accuracy impossible. 



Variation. — A second specimen 79 mm. long differs in having the third 

 dorsal spine distinctly longer than the last : the cross-bauds on the back are more 

 distinct, and the spots of the head extend on to the lower portion of the sides of 

 the body. A third specimen, 99 mm. long, has only six anal rays; its light dorsal 

 stripe is more pronounced and it has no dark spots on the back or sides, while 

 the head markings are reduced to brown rings around pale pinkish spots; che 

 fin-markings also are more or less obsolete. 



Affinities. — This species differs from Paracoiirojyogon, in which genus it 

 was placed by Ogilby, in the absence of palatine teeth and the form of its
