formed of a succession of small longitudinal ridges, extending 

 on the middle of the scales ; it extends on the caudal. The 

 dorsal fin is large ; its fifth spine is the longest ; the membranes 

 of the second portion are covered with scales to the fourth of the 

 height of the fin. The caudal is rounded, and its membranes are 

 covered with scales nearly up to the middle of their length ; the 

 anal is long, with its spines strong ; the second is much longer 

 ban the first, and a little more so than the third ; it is covered 

 with scales at its base, as are also the pectorals. The ventrals 

 are large, their first ray is prolongated in a filament, having about 

 the fifth of the length of the fin ; the spine is strong, and nearly 

 two -thirds of the length of the rays. 



The general colour is purple, becoming reddish on the lower 

 parts. The upper surface of the head is green, and the sides of 

 a rather brilliant purple ; the lips and internal circle of the eye are 

 of a flesh colour ; all the scales of the body are bordered with a 

 dark tinge ; the dorsal fin is of a purplish green, with the spines 

 purple ; the caudal and anal purple ; the ventrals are pink, with 

 their external third black ; the spine is purple'; the pectorals 

 yellow ; eye brown. 



From the Murray Eiver ; average length, 14 inches. 



Nota. — I have a monstrous specimen of this sort which has 

 an accidental spine on the left side of the third dorsal. The eye 

 is red. 



The smaller specimens are more elongate than the adult. 



In one specimen, the soft rays of the dorsal number thirteen . 

 in another those of the anal nine. I have received from 

 Deniliquin, by Mr. Christy, a monstrous specimen of this sort, 

 in which the ventrals are rudimentary, and only formed of one 

 distorted spine and three rays. The second spine of the anal is 

 also quite distorted, and there are eleven soft rays to the anal.
