### 1. On the zeros of a class of generalised Dirichlet series-XVIII (a few remarks on littlewood's theorem and Totchmarsh points)

In this paper the number of the zeros of generalised Dirichlet series satisfying some reasonable conditions is discussed.

### 2. On the zeros of a class of generalised Dirichlet series-XIX

In this paper, an alternative and simpler proof of the main general result of Part XVIII is given. The proof is based on the classical van der Corput lemma and Montgomery-Vaughan inequality, and except for these tools the arguments are self-contained.
