BUTTICBFLY BREAM. 

 Ti/pi: locality: — Caloundra Bank, S.Q. 



Body elliptical, the ventral contour as much or a little more arched than 

 the dorsal, which is linear and feebly declivous behind the origin of the dor.sal, its 

 width 1-S to 2-1 in its depth, which is 3 to 3-2 in its length and as much as to one 

 tenth less than the length of the head. Caudal peduncle slender, its least depth 

 1-8 to 2 in its length and 2-8 to 3 in the depth of the body. Head one sixth to 

 two ninths longer than deep, its upper profile evenly and gently convex, its width 

 somewhat less than half its length, which is 3-1 to 3-25 in that of the body. Snout

 Diameter of eye 1-5 to 1-67 in the length of tlie snout, 3-67 to 4 in that of the
