J. — Authorities for the Sections, Views, and figures of Fossils 

 in this work. 



The following are the authorities for the more important illustrations of this 

 Manual. The works mentioned are those from which the figures or views have 

 been taken : and although generally the original publications, they are not all 

 so. When the figures have been made from original drawings not before pub- 

 lished (the fact with regard to about 150), the reference is distinguished by an- 

 nexing a point of interjection (!). Many of the new figures by Meek under the 

 Mesozoic and Cenozoic are from a manuscript Palaeontological Report of 

 Lieut. G. K. "Warren's Expedition to the Upper Missouri, by Messrs. Meek and 

 Hayden, the publication of which, unfortunately for science, has been deferred.
