*Owing to the impossibility of communicating with Dr. Shnmard during the
printing and engraving of the present report, I have been unable to fill up the
gaps in the above list of figures made up from the references in the article on
paleontology. This want of supervision on the part of the author will also explain
the existence of sundry discrepancies between text and plates.
