Abstract
Location of esterases and nerve arrangement is studied inSinghiatrema longifurca andParadistomoides orientalis. Both the trematodes possess a pair of cerebral ganglia connected by cerebral commissure. From here three pairs of nerves proceed to anterior and posterior sides. Anterior pairs, interconnected by transverse commissures and connectives innervate the oral sucker and the anterior tip. Of the posterior pairs, ventrolaterals are well developed in both. InS. longifurca nervous organization is highly complicated with many branches.P. orientalis also sends a number of branches to various organs. Both parasites possess many presumptive neuro-secretory and sensory cells. Various degrees of esterase activity in both worms is located in excretory vesicle and ducts, suckers, genital pore, gonads, oviducts and eggs.
