Histological and Histochemical Observations On the Reproductive Tract of the Hermaphrodite Pond Snail Lymnaea Stagnalis (L.)

INTRODUCTION In order to relate the morphology of the different parts of the repro- ductive tract to their function, several pulmonate species, Basom- matophora as well as Stylommatophora, have been investigated. These studies have been histological (e.g., ABDEL-MALEK, 1954; ROTH & WAGNER, 1957; DUNCAN, 1958) and to a lesser extent, histochemical (DUNCAN, 1960; Lusis, 1961; SMITH, 1965). In this respect the ex- tensive light and electron microscope study of the Schistosoma mansoni vector Biomphalaria glabrata deserves special mentioning (DE JONG- BRINK, 1969).
