For explanation see text. incrlanyi reported by Halton et al. (1968). In both monogeneans the cecal epithelium is composed of two distinct cell types ; hematin cells alternate with a previously unrecognized connecting cell system which covers all areas of the cecal wall between adajacent hematin cells. No inter-cellular junctions have been ob- served within the flat, sheet-like connecting system, and the view of Halton et al. (1968) that this exists as a syncytium is supported. There are certain differences in the ultrastructure of the gastrodermal com- ponents in the two species. Halton ct al. (1968) recorded that in D. tnerlangi protoplasmic projections occur on the free surface of both types of cecal cell. In epithelium suggests, however, that this plane of sectioning does not represent the actual process of detachment; scale bar, 4 /*..
