The cytoplasm of the leptomonas form of Herpetomonas muscarum contains a parabasal body, mitochondria, and so-called volutin granules. The parabasal body consists of neutral lipid (probably triglyceride), lipoprotein, and DNA. The mitochondria are in the form of granules. The volutin granules are more numerous and smaller than the mitochondria. The volutin granules appear to be composed of ribonucleoprotein. Glycogen is dispersed homogeneously in the cytoplasm. The cytoplasm is rich in RNA and protein. The nucleus is DNA-positive. Near the parabasal body lies a basal granule; a long flagellum arises from it. A flagellar vacuole lies near the base of the flagellum.
