Cytological changes in the corpus luteum and resorptive bodies of P. americana were studied. Ooresorption is the outcome of unfavorable physiological conditions. No new tissue is formed in the corpus luteum and continuous tissue destruction and degeneration are observed. The tunica propria is of a proteoid nature. The proteoid material of the pyknotic nulei is gradually reduced as a result of continuous destruction and absorption of the chromatin. In the early stages of corpus luteum formation there are many pyknotic nuclei, but in the later stages their numbers steadily diminish. The pyknotic nuclei are irregularly distributed in proteoid syncytial cytoplasm. In the resorbed oocyte, the intensely proteoid simple follicular epithelium becomes highly proteid and stratified. It contains numbers of Golgi corpuscles and mitochondria. The proteoid tunica propria is firmly attached to the follicular epithelium. The proteoid nature of the cytoplasm is gradually intensified; the ooplasm contains large numbers of scattered Golgi corpuscles, mitochondria, protein yolk bodies and lipid bodies, which in time diminish. The mitochondria always have a granular appearance.
