The differentiating sebaceous cells in three species of galagos have different structural configurations of cytoplasmic membranes. The type unique to G. senegalensis consists of groups of six tubules, which intersect at common centers. The tubules of this configuration probably represent a specialized form of agranular endoplasmic reticulum. A second specialized form of agranular endoplasmic reticulum is found in all three species of galagos; this configuration consists of grids of intersecting tubules that are ∼400 Å in diameter. Individual tubules of agranular endoplasmic reticulum are also abundant in the cells.
Another disposition of cytopalsmic membranes, found only in G. crassicaudatus, is significantly different from the others. In this structure, membranes intersect in three planes to form hexagrams. All of these configurations are closely associated with single, dispersed profiles of predominantly agranular endoplasmic reticulum and sebum vesicles.
