The orbital structure of triaxial models with weak central density cusps, ∝ r−, < 1, is investigated. The stability of the x- (long-) axis orbit – and hence the existence of box orbits – depends sensitively on; the range of model shapes for which the x-axis orbit is stable becomes progressively smaller as approaches one. The banana and fish boxlets in the x − z (long axis–short axis) plane are stable over a wide range of model parameters. The boxlets in the x − y and y − z planes are generally vertically unstable.
