Attention is drawn to the similarity of certain sediments or breccia beds of exotic composition in Turkey to the Argille scagliose formation of Italy, and the explanations that have been given for them.

The discussion by McCallien points out that these items have been considered previously and that as far as the Argille scagliose is concerned, he and Bailey still favor a tectonic interpretation.
