The distribution, morphology and cytochemistry of the eosinophilic granule cells in the gut of the rainbow trout,Salmo gairdneri, were studied using light and electron microscopes. Granule cells were associated generally with the propria of the gut wall, the majority being arranged in a definitive layer, as a stratum granulosum. The cytoplasm of the eosinophilic granule cells contained numerous spherical, membrane‐bound, homogeneous electron‐dense granules, ranging from 0·1–1·3 urn in diameter. A portion of the cytoplasm located towards one pole of the cell was usually devoid of organelles other than ribosomes. Whatever their location, the eosinophilic granule cells were always associated with fixed connective tissue cells, referred to here as ‘ensheathing’ cells. Phospholipid, acid mucopoly‐saccharide and the activities of alkaline phosphatase, acid phosphatase, arylsulphatase and 5‐nucleotidase were demonstrated in the granules. It is hypothesized that the ‘ensheathing’ cells and eosinophilic granule cells constitute a part of the bod
