POSTSCRIPT. 



The Plates of the present A^olume, with their accompanying- pages of 

 explanations, were nearly all printed in 1881 and 1882, and the last of the 

 series, in Febrnaiy, 1883. Most of the other illustrations, also, were 

 completed by the latter date. In consequence of an unexpected delay in 

 printing the text, some of the figures prepared for the Monograph first 

 appeai'ed elsewhere. 



An extended abstract of this volume, with 102 illustrations, was 

 prepared by the author, in July, 1884, for the Fifth Annual Report of the 

 Director of the United States Geological Survey, and references to tlie 

 pages of this Report will be found in the preceding Synopsis. 



With the permission of the Director of the United States Geological 

 Survey, an author's edition of 500 copies of this work was printed in Feb- 

 ruary, 1885.
