Microphallus pirum (Afanas'ev, 1941). FIGURE 11. Paiittnis hirsutiusculus (about 31/f>X). Arrows indicate metacercariae of MicropliaUns pintui. Studies of the life cycle of trematodes of the genus Microphallus have been mainly concerned with fresh-water species. A notable exception is the work of Stunkard (1951) with M. linmU, whose metacercariae were found in the horse- shoe crab, Limuhts polyphemus. His work included a critical consideration of the systematic position of the genus Microphallus. During the present study the metacercarial stage of M. piruui was found at- tached rather insecurely to the inner lining of the abdominal wall and to the tissue supporting the viscera of a hermit crab, P. hirsittinsciihis (Fig. 11). They were usually most numerous at the juncture of the cephalothorax and abdomen, but in heavy infections these cysts occurred throughout the abdomen and occasionally.
