This is midbody of a female Schistosoma haematobium.  The large ovoid body to the right is the ovary which releases its eggs through an oviduct which extends upwards in this photo, then passes anteriorly (to the left) where it enters the ootype, seen here as a dark red body to the left of the ovary.  The tube leading from the ootype is the uterus. Vitelline granule can be seen to the upper right.  100x
