Furcocercous cercariae infecting freshwater snails in Malabar: two new species from Lamarck and (Hutton).

The present paper describes two new species of furcocercous cercariae, sp. XVIII Malabar n. sp. and sp. XIX Malabar n. sp. infecting the freshwater snails, and respectively in the Malabar region of Kerala. sp. XVIII Malabar n. sp., is a distome, pharyngeate, non-ocellate, longifurcate furcocercous cercaria with two pairs of penetration glands and 16 pairs of flame cells and recovered from . sp. XIX Malabar n. sp., is also a distome, pharyngeate, longifurcate cercaria with a pair of unpigmented eyespots and 20 pairs of flame cells and recovered from . Sporocysts of both the cercariae developed in the digestive glands. The present paper describes the cercariae and compares them with related species to establish their systematic position.
