FISHES. — MCCULLOCH. 195 



Genus Holacanthus, Lacepede. 



Subgenus Ch^todontoplus, Bleeker. 



Holacanthus (Ch^todontoplus) personifer, 

 McCulloch. 



(Plate Ivi., fig. 2.) 



Holacanthus {Chcetodonfoplus) personifer, McCulloch, Rec- 

 W. Austr. Mus., i., pt. 3, 1914, p. 221, pi. xxxi. 



Chcetodo7itoplus conspicillatus, Ogilby, Mem. Qld. Mus., iii., 

 1915, p. 114 (not Holacanthus conspicillatus, Waite). 



Variation. — Five specimens, 110-193 mm. long, resemble 

 those of similar size described by Ogilby, and differ from the 

 typical example in the following details. Younger specimens 

 are deeper than adults, the depth before the v^entrals in the 

 smallest being 1.8 instead of 2.3 in the length to the hypural 

 joint. Smaller examples (Plate Ivi.) have the head, nape 

 and isthmus nearly uniform brown, this colour being only 

 broken up by white spots in larger examples. All have the 

 caudal fin yellow^ with a narrow grey mai-gin ; in the type 

 this fin is largely black with an imperfect lunate submarginal 

 yellow band. 



Synonymy. — Ogilby has regarded H. personifer as a colour 

 variety of H. conspicillatus, Waite, but there is apparently no 

 justification for this supposition. Ten specimens are know n, 

 ranging from 110-290 mm. in length, Avhich exhibit the 

 regular alteration in both form and colour-marking described 

 above. In none, however, do the variations encroach on 

 the characteristic markings of H. conspicillatus, which are 

 well shown in Waite's figure of that species, and which do 

 not differ in the two typical specimens. 



Loc. — Wide Bay, Queensland. 



Family SC'ORP.ENID.F]. 



Genus Liocranium, Ogilby. 



Liocranivni, Ogilby, Proc. Roy. kSoc. Qld., xviii., 1903, p. 

 23 (L. prceposiium, Ogil.). 



This genus is near Snyderina, Jordan & Starks,^ but differs 

 in having four instci'd of five ventral rays.
