    The extended quasidilaton theory is one of the simplest Lorentz-invariant massive gravity theories which can accommodate a stable self-accelerating vacuum solution. In this paper we revisit this theory and study the effect of matter fields. For a matter sector that couples minimally to the physical metric, we find hints of a Jeans type instability in the IR.

Searches for a fully satisfactory theory have led to mod-els of massive gravity incorporating a quasidilaton eld [12{16]; the extra eld is used to stabilize the metric per-

    extended ducial metric and in cosmological solutions plays a similar role to the scale factor. The coupling constant ˙ between the massive graviton and the quasidilaton is introduced to stabilize the self-accelerating solution in the absence of matter [19]. Note that the extended ducial metric is dynamical whereas f is always a coordinatization
