title: [Morphometry and histology of the eye of Callimico goeldii (Thomas 1904, callimiconidae primates) (author's transl)].
abstract: The histologic anatomy of the eye of Callimico goeldii is described and histometric data are communicated. The retina is treated with special attention. The eye of Callimico features all characteristics of a visual organ adapted to diurnal activity as is known from many higher primates and man. The well-differentiated Fovea centralis and the numerical relations of the three retinal neurons, which are clearly reduced from the periphery towards the center of the retina, indicate a particularly high degree of centralization ("Zentralisationsstufe" sensu Rohen). Similar numerical relations are found in the taxonomically related families Cebidae and Callithrichidae. A high degree of centralization is understood to facilitate a good visual resolution. The eyelid apparatus is differentiated like in other higher primates. The eye muscles contain extraordinarily many nervous-muscular entities that are interpreted to serve as nervous regulatory functions. The histologic results relate well with certain behavioral phenomena of this species.
