one-sixth of the total height ; it is strongly bilobed ; the anus is 
rather long but narrow ; it is formed of three spines and six soft 
rays ; the first spine is ¥ery minute, the second about three times 
its length, and the third about four times as long as the second ; 
this third is slender, and has some very feeble denticulations on 
its inner side ; the pectorals are contained one and one-half times 
in the length of the head ; it has a first hard ray and fifteen soft ; 
the ventrals have one spine and eight so^t rays, the spine being 
about two-thirds of the length of the first soft ray. 
The general colour is of a beautiful yellow brown, with golden 
tinges ; it degenerates into a brilliant white on the belly, the 
edge of which is rather yellow ; the pectoral is bordered superiorly 
with black ; the caudal tinged with red. The mouth has no 
teeth, and there are no barbels ; the operculum and scales are 
covered with fine concentrical strise ; the eye is of a pale 
yellow ; the mouth is extensible ; the eye of moderate size ; the 
second portion of the air-bladder is very elongate, and about two 
and one-half times as long as the other. 
I have only seen one specimen in the Melbourne Market. It had 
been found in the Mordialoc Eiver ; but several others were sent to 
the Acclimatisation Society from Sydney, and there is no doubt 
that it is an introduced fish, but I do not know from what 
country it came direct. 
Apart from this variety, which seems remarkably constant, the 
common Chinese Auratus is very widely spread in Melbourne, and 
presents all its usual beautiful colours. 
3.— NEOCOEASSIUS. 
This is the only Gyprinoul sort on which I have considerable 
doubts as to its having been imported. The two specimens 
I have seen of it were caught in the Saltwater Eiver, at 
Eootscray, during the cold weather. The first was found a 
year ago, and I was so convinced that no fish of this family was 
to be found in Australia, that I thought it belonged to some 
imported sort of Corassius, of which it has the general appear- 
ance ; but a second specimen having been recently found in the 
same locality, I examined it with more care, and I find it 
impossible to place it in any of the groups mentioned by Dr. 
Gunther, or any other author. I cannot, on the fresh specimen,
