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 fonrth 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. 
Trom the Murray Eiver ; average length, 14 inches. 
Not A. — 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.
