摘　　要：本文利用吲哚乙酸酯法（Ｉｎｄｏｘｙ１－ａｃｅｔａｔｅｍｅｔｈｏｄ）观察了酯酶在雷氏叶形吸虫神经系统的定位。Following the localization of esterase by Indoxylacetate method,the nervous system in toto has been traced in Phyllodistomum lesteri.A pair of cerebral ganglia,connected to each other by a transverse commissure,consititute the brain mass which lies immediately posterior to the pharynx and dorsal to the oesophgus.Three pairs of longitudinal nerve trunks,dorsal,ventral and lateral,arise from the ganglia,run to the anterior and posterior parts of the body.A pair of pharyngel nerve,branched from the antero-ventral nerve trunks,innervate the pharynx.Three nerve trunks extend posteriorly near the body end.The Plstero-ventral pair is the best developed and its branches lead into the acetabulum forming a nerve ring,while the three nerve trunks extend anteriorly in the oral sucker to form a nerve ring.All longitrdial nerve trunks are connected to each other transverse commissurses which are further joined with oneanother by some connectives forming a nerve network.
