A class of perfect-fluid ''anti-Newtonian'' cosmological solutions in higher-order gravity will be discussed. In particular, we present the integrability conditions of such gravity models using the covariant consistency analysis formalism. We show that, unlike in General Relativity, these anti-Newtonian solutions exist subject to the solution of an integrability condition equation we derive, and that they are not silent cosmological models. We also present the set of evolution equations governing the linear perturbations of matter, expansion and Ricci scalar for this class of models.
