Abstract Previous studies of the anatomy of the oncomiracidia of the hexabothriids Rajonchocotyle emarginata and Hexabothrium appendiculatum have been made on unhatched larvae viewed through the egg shell or on larvae pushed out of the egg by coverslip pressure. A study of freshly hatched, free-swimming oncomiracidia has permitted a more detailed anatomical study especially of the gland cell system, the distribution of locomotory ciliated cells and surface sensilla and the flame cell system. Anatomically, the two larvae are closely similar but the oncomiracidium of R. emarginata possesses spherical refringent droplets in the locomotory ciliated cells and, in the head region, a pair of translucent bodies which may be photoreceptors. The oncomiracidia of both parasites possess posterior body gland cells with ducts entering the haptor. Such gland cells have not been recorded previously in the larvae of hexabothriids or in those of other polyopisthocotyleans and the function of these and other gland cells is discussed.
