224 "ENDEAVOUR" SCIENTIFIC RESULTS. 



1. Pseudorhombus spinosus. 



Pseudorhombus spinosus, McCulloch, Biol. Res. 

 "Endeavour," II, p. 129, pi. XXV (1914). 



Depth of body 2^ to 2^ in the length, length of head 

 3f to 3*. Dorsal profile of head evenly convex, not 

 notched in front of eyes. Snout longer than eye, diameter 

 of which is 4| to 5 in length of head ; lower eye scarcely 

 in advance of upper, which is separated from upper 

 edge of head by a space equal to f its diameter. Maxillary 

 extending to below posterior ^ or \ of eye, or not quite 

 as far, length about twice in head; lower jaw not pro- 

 jecting, a knob at the syinphysis, length If to 1| in head. 

 Teeth of upper jaw rather small laterally, not close-set, 

 enlarged anteriorly ; teeth of lower jaw stronger, a single 

 pair of enlarged teeth anteriorly. Gill-rakers "palmate" 

 (short, broad, the distal margins spinulate) ; 10 on lower 

 part of anterior arch. 3 Scales of ocular side cycloid or 

 weakly ctenoid, often more or less embedded in the skin ; 

 those of blind side cycloid; 78-86 scales in a longitudinal 

 series, 4 26-30 between lateral line and highest point of 

 dorsal profile. Height of arch of lateral line 2| to 3 in 

 length of same; a short accessory branch, not reaching 

 base of dorsal fin. Dorsal 72-75 (76) ; commencing well 

 in front of both nostrils of blind side, and at a distance 

 in front of eye equal to or greater than its diameter; a 

 line connecting base of first ray with posterior nostril, 

 if continued, passes above hinder end of maxillary. Anal 

 57; tip of first interhsemal spine generally projecting 

 through the skin on median line, below vent and imme- 

 diately in front of first anal ray. Left pectoral with 10 

 to 12 rays (7 to 9 branched), base almost horizontal, 

 length If to 2 in head. Caudal with 2/13/2 rays, middle 

 rays longest, li to 1^ in length of head. Length of 

 caudal peduncle 2^ to 2| in its depth, which is 2f to 2f 

 in length of head. Light broAvnish or greyish, with 

 darker spots and annular markings, and with 3 large 

 conspicuous ocelli arranged thus .: ; fins generally 

 spotted and blotched with brown. 



Uab. Western Australia; southern Queensland. 



Described from 11 specimens, 95 to 245 mm. in total 

 length. 



:; Counted on blind side of head. 



4 Counted from upper angle of gill-opening across arch or 

 lateral line, and from thence above the straight portion.
