Abstract: The Ramanujan $ \tau$-function satisfies well-known congruences modulo the so-called exceptional prime numbers $ 2,3,5,7,23,691$. In this paper we prove new congruences related to the irregular primes $ 131$ and $ 593$, involving generalized class numbers. As an application we obtain distribution results. We obtain a new proof of the famous $ 691$ congruence and congruences of the related Rankin L-funtion.
