A novel system of dark field illumination suitable for stereoscopic microscopes is described in which a beam of light is directed between the objectives. The system is used in an examination of the pattern of pseudopodia produced by the foraminifer <i>Reophax moniliformis</i> Siddall in which groups of pseudopodia are often seen to make abrupt obtuse angle changes of direction between about 130° and 160°.
