234 "ENDEAVOUR" SCIENTIFIC RESULTS. 



in the Australian Museum, the scales of both sides of the 

 body are ctenoid (see page 279). 



Pseudorhombus polyspilus, Bleeker, is closely 

 related to P. arsius, but Dr. L. F. de Beaufort informs 

 me that the two species are, in his opinion, distinct.

Pseudorlwmbus elevatus, Ogilby, Mem. Queensland Mus., 

 I, 1912, p. 45. 



Depth of body 1 to twice in the length, length of 

 head 3 to 3-f. Dorsal profile of head more or less 

 notched in front of eyes. Snout equal to or a little 

 longer than eye, diameter of which is 4 to 4f in length of 

 head ; lower eye very slightly in advance of upper, which 

 is separated from upper edge of head by a space equal 

 to or ^ its diameter. Maxillary extending to below 

 middle of eye or not quite as far, length 2^ to 2| in head ; 

 lower jaw scarcely projecting, a knob at the symphysis, 

 length about If in head. Teeth all very small and rather 

 close-set, scarcely enlarged anteriorly. Gill-rakers 

 slender, about 5 times as long as broad, their inner edges 

 feebly spinulate ; 13 to 16 on lower part of anterior arch. 

 Scales of ocular side ctenoid, those of blind side cycloid ; 

 67 to 71 in a longitudinal series, 25 to 28 between lateral 

 line and highest point of dorsal profile. Height of arch 

 of lateral line about 2| in length of same; accessory 

 branch reaching base of eighth to tenth ray of dorsal 

 fin. Dorsal 68-72 ; commencing above or a little in front 

 of level of anterior nostril of blind side, and at a distance 

 in front of eye equal to about its diameter. Anal (54) 

 55-58; end of first interhaemal spine projecting through 

 the skin on the blind side behind vent and above first or 

 second anal ray. Left pectoral with 11 or 12 rays (6 to 

 8 branched), base oblique, length about 1^ in head. 

 Caudal with 2/13/2 rays, middle rays longest, 1 in 

 length of head. Length of caudal peduncle 2^ to 3 in 

 its depth, which is 2f to 3 in length of head. Pale 

 brownish, with an indefinite dark blotch at the junction 

 of the straight and curved oortions of the lateral line, 

 and a small dark rtpoi, oeiimd middle of straight portion ; 

 five series of inconspicuous annular markings; fins with
