Abstract
We had the opportunity of examining about twelve snakes (Tropidonotus natrix) all from the same district, and found in almost every case a heavy infection with various Trematodes. In the lungs we found Saphedra longicollis, and in the small intestine Leptophallus nigrovensis and Cercorchis nematoides, together with several specimens of Odhneria bolognensis n.g., n.sp. We will discuss the systematic position of this new genus in another part of this paper.
