Abstract

Sporocysts capable of producing active miracidia were recovered from the upper branchial chamber of the snail species, Melania tuberculata and M.scabra. The non-ocellate miracidium was characterised by the presence of 22 epidermal plates in four tiers, an apical gland with four nuclei and two penetration glands. Sporocysts were of two types, one producing active miracidia and the other in which daughter sporocysts and miracidia were found. These sporocysts were characterised by the presence of bunches of circular muscles at intervals and also by the presence of a network of muscle fibres at the anterior and posterior one fifth regions. Development of the miracidia took place in compartments. Histochcmical tests were carried out as regards glycogen, protein, lipids and phosphomonoesterases.
