Explanation of the Plates. 
The colored Plates are reproductions of drawings made by the author, 
who likewise made all the photographs for the half-tone illustrations. 
Both the colored Plates and the figures of the bones of the skeletons on 
the other Plates were made direct from material in the Collections of the 
United States National Museum, which was loaned the author for the 
purpose.
