    Notes: Anatomical analysis of the forebrain and midbrain of Anelytropsis, Dibamus and feyliniids reveals structural similarities with those of skinks and snakes. Skinks and feyliniids are probably derived from a common ancestral stock. This is suggested by mutual reduction of several telencephalic nuclei, by similar trends in the development of the dorsal thalamus, and by similarities in the lamination of their optic tecta. Anelytropsis, Dibamus, feyliniids and snakes show interdigitation of the periventricular gray zones of the optic tectum and enlargement of lamina 7 of the posterior colliculus. Of these three taxa, Dibamus is most similar to burrowing snakes and many of its brain characters are intermediate between skinks and burrowing snakes. These similarities may suggest common ancestry between Dibamus and snakes rather than parallelism.

    Reproductive systems of the north indian langur (Presbytis entellus entellus Dufresne) (1971)

    Notes: The gross anatomy and histology of the gonads and accessory sex organs are described for male and female Presbytis e. entellus. The langur differs from other catarrhine monkeys in certain specialised characters. The “sexual skin” is not comparable to the true sexual skin of the Cercopithecinae which exhibits cyclical change during the various phases of reproduction; it is nevertheless fully developed in the adult male and serves as one of the secondary sexual characters.Certain aspects of the reproductive system strikingly resemble those of man. The combined testicular weight (0.07% body weight) is similar to the human (0.08%), and the male has ampullary glands. The cervical canal is straight like that of a baboon or man. The corpus luteum (except in the lactating female) is a hollow glandular structure. Extensive hemorrhage which always accompanies ovulation in the langur, does not appear to be a common phenomenon in any other catarrhine for which ovulation and the development of corpus luteum have been studied. The hemorrhagic remains are retained for a long time in the ovulated follicle.The ovary is characteristically large and averages 0.74 gm without corpus luteum and 1.57 gm with corpus luteum, a feature never reported in any other catarrhine monkeys. The pre-ovulatory follicle may attain a size of 14 × 14 mm.

    The external glial limiting membrane in Macaca: Ultrastructure of a laminated glioepitheliumSupported by U.S.P.H.S. grant NS 07044. (1973)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The external glial limiting membrane in Macaca is a multilaminar epithelium-like mantle formed by the perikarya and interdigitating cell processes of astrocytes. It is separated from the overlying subarachnoid space by a typical basement membrane. Tonofilaments, about 100 Å in diameter, course through the cytoplasm of the processes in sheaths which run in different planes in successive layers of the mantle, forming a course brushwork. Beneath the surface plasma membrane of the superficial astrocytes is a filamentous layer, 500-700 Å thick, which is composed of microfilaments, about 50 Å in diameter. These microfilaments were continuous with the inner aspect of the plasma membrane. The tonofilaments appeared to terminate in the microfilamentous network. The similarity of these microfilaments to the cytocholasin B-sensitive microfilaments of epithelial cells suggested contractile properties and their participation in the motility of glial cells at the border of the brain and subarachnoid space.
