belly and fins yellow ; the centre of the scales is generally dark. 

 In other specimens the hack 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 Tarra, 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. 



C^SIOPEBCA. 



Serranus, Rich.; anthias, Qimther. 



The very pretty fish on which I propose forming this new 

 genus is, in general form, very much like Arripis, and might at 

 first sight be taken for a Coesio. By its operculum and prseoper- 

 culum being denticulated, and its palatines being armed with 

 teeth, it must be placed with the Percidce; but even the beauty 

 and disposition of its colours convey the idea of a Coesio. 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.Grunther, in leaving provisionally this sort with his Anthias, 

 states that it will probably form the type of a separate genus.
