belly and fins yellow ; the centre of the scales is generally dark. 
In other specimens the back is green, and the belly white, with 
a black longitudinal spot on its lower part ; the fins of an orange 
colour, bordered with black ; the ventrals entirely of that colour ; 
the body has more or less black spots ; the eye is silvery. 
This pretty little fish is found in the lower Yarra, where the 
water is brackish. Most of my specimens were obtained in 
Captain Sinnott’s dock. The general length is about 2| inches, 
but I have one which measures a little over 3. 
CJ3SIOPEECA. 
Serranus, Rich.; anthias, Gunther. 
The very pretty fish on which T propose forming this new 
genus is, in general form, very much like Arripis, and might at 
first sight be taken for a Ccesio. By its operculum and prseoper- 
culum being denticulated, and its palatines being armed with 
teeth, it must be placed with the Rercidce; but even the beauty 
and disposition of its colours convey the idea of a Ocesio. It 
would have been a Centropristes for Cuvier, if its head was not 
entirely covered with scales. Teeth very numerous, villiform, 
those of the inner row directed backwards ; two very blunt and 
small canines on each jaw ; a few sharp, arched teeth, larger than 
the others, on each side of the lower jaw ; teeth on the palatine 
bones, disposed in a transverse line, in three groups ; fins in their 
greatest part covered with small scales ; one dorsal ; operculum 
with two spines — the upper small, the other larger ; dorsal with 
ten spines, and anal with three ; all the parts of the head entirely 
covered with scales ; those of the body moderate or rather large. 
Dr.G-unther, in leaving provisionally this sort with his Anthias, 
states that it will probably form the type of a separate genus.
