Cuar. Head small, obliquely raised above the axis of the body ; dorsal 
placed opposite to a larger anal; apices of the jaws raised to a line with the 
dorsum, which is straight ; the ventral margin is much arched ; sides usually

difficulty of counting the rays in some of the fins of this small species.
