Methods of Investigation: Use of Infrared Light for the Study of Chitinozoa

Certain methods of studying the surface of Chitinozoa and their internal structure are briefly described. A compressed account is given of the classification of Jansonius based on the structure of the prosomal complex and the tegment. Mention is made of the structural complexity and diversity of the prosomal complex in certain genera, and of the possibilities which the use of infrared light affords for study of the internal structure and the role of such study for correct identification of genera and establishment of their stratigraphic importance.
