Histological and histochemical tests give similar results for the midguts of Floridobolus penneri (Causey, 1957) and Narceus gordanus (Chamberlin, 1943). The peritrophic membrane is composed of basic proteins and acid mucopolysaccharides. The epithelium contains basic proteins and large lipid concentrations, including glycolipids, phospholipids, and fatty acids. The luminal epithelial border gives reactions for protein-bound amino groups, tyrosine and phenolic compounds, and neutral fats. Protein-bound amino groups, glycoproteins, acid mucopolysaccharides, and bound lipids are found in the collagenous basement membrane. The circular and longitudinal muscle layers contain basic proteins, tyrosine and phenols, and bound fats. A large glycogen concentration occurs within the sheath membrane. This region, which is primarily basic protein, also gives positive reactions for protein-bound groups and both tyrosine and phenols.
