OKIGINAL DEAWINGS FOR THE PALEONTOLOGY OF 

 NEW YORK, VOLUME VIII. 



In order that full credit may be given to the several artists who 

 have contributed to the illustration of the volume, the following 

 explanation of the source of the figures is given. Since this 

 work was commenced many years ago important changes have 

 occurred in the organization then existing, and not a single 

 draughtsman has been continued from the commencement. 

 Some of the drawings especially of the Productidae and others 

 were made by Mr. F. B. Meek*, and his work was followed by 

 that of Mr. R. P. Whitfield. As these plates were printed the 

 name of the person who had done the greatest number of figures 

 was usually given at the bottom of the plate as delineator.! In 

 some cases it may be possible that equal justice has not been 

 done. In order to meet this question and to do equal and exact 

 justice to every one who has contributed to this work the follow- 

 ing list of figures and their authors has been compiled. In the 

 explanations of the Plates of the Brachiopoda Articulata, begin- 

 ning with Plate V, the name of the author of each original 

 drawing will be given.

List of figures upon the lithogeaphic plates accompanying 

 Paet I OF Vol. VUI Brachiopoda Inarticulata, with their 



AUTHORSHIP. 



[On the pages of explanations accompanying the plates to the 

 second part of this work, upon the Brachiopoda Articulata, a 

 statement is given of the authorship of each one of the original 

 drawings ; the name appearing at the bottom of the plate as 

 delineator being that of the draughtsman to whom the largest 

 number of drawings is to be credited. These statements in detail 

 were not given on the explanations of the plates in Part I and 

 are hence inserted here. All the plates for this part of the work 

 have been drawn on stone by Mr. Philip Ast.]
