We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4parity doublet in $D=2+1$. They are of higher order in derivatives and aredescribed by a totally symmetric rank-4 tensor without extra auxiliary fields.Despite the higher derivatives they are ghost free. We find gauge invariantfield combinations which allow us to show that the canonical structure of thespin-4 (spin-3) models follows the same pattern of its spin-2 (spin-1)counterpart after field redefinitions. For $s=1,2,3,4$, the spin-$s$ self-dualmodels of order $2s-1$ and the doublet models of order $2s$ can be written interms of three gauge invariants. The cases $s=3$ and $s=4$ suggest a restrictedconformal higher spin symmetry as a principle for defining linearizedtopologically massive gravity and linearized "New Massive Gravity" forarbitrary integer spins. A key role in our approach is played by the fact thatthe Cotton tensor in $D=2+1$ has only two independent components for anyinteger spin.
