SYNOPSIS. Many of the sub‐pellicular and infraciliary structures in protozoa have proved difficult to study with standard thin‐sectioning technics. When these structures are viewed in isolated and fragmented form, many of the thin‐sectioning difficulties are circumvented. Langmuir‐trough isolation followed by critical‐point drying, as well as thin sectioning, were used in this study to determine the patterns of sub‐pellicular microtubules and fibrils interconnecting kinetosomes of membranelles and cirri of Euplotes eurystomus. The fibrillar network in the bases of these ciliary organelles is presented in some detail and apparent variations in pattern are noted. Functional aspects of some of the structures are discussed. With special preparation nearly whole Euplotes may be obtained for study in the electron microscope. Fused cilia were frequently obtained and their ultrastructure was studied.
