Haueri, and C. Stangeri, my interpretation of the structure of these fruits is chiefly founded on C. Stangeri, as this seems the most perfectly preserved.

Zeiller of writing anonymously my Review of his Carbon-Flora, contributed to the Geol. Mag., which communication M. Zeiller had neither seen nor was aware of, till after its publication—especially as the paper more fully explaining my views on this subject was published in the Quart. Jour. Geol.
