Abstract
The 1953 field reports refer to several rock units of the Cambrian sequences of the Undilla Basin without defining the units. These units were established in previous years, but all the records and prepared reports were destroyed in the autumn of 1953. The author used this nomenclature in his field reports on the assumption that it would be known to prospective readers. In the present report the definitions are given in a brief and preliminary form. The field maps show the distribution of the rock units, but, as the field reports contain no explanatory sections, these are presented here. The study of the collections included the examination of the lithology and definition and determination of the vertical distribution of fossils. The results of the lithological examination will be given later. The vertical distribution of genera and species of fossils, however, shows the existence of a sequence of biozones (species-zones); it indicates the presence of four fossil stages in the Middle Cambrian sequence and is presented in Chart 2. The fossil list is incomplete, and the nomenclature applied is not final.
