REPORT OF C, A. WHITE, M. D. 
LETTER OF TRANSMITTAL. 
WASHINGTON, D. C., April 7, 1880. 
Sir: I have the honor to herewith transmit Contributions to Inverte- 
brate Paleontology, Nos. 2-8, together with thirty-two pilates of illus- 
trations. The character of these articles is set forth in the remarks 
which precede each, respectively, and they have been made as complete 
as the circumstances attending the closing up of the affairs of the Sur- 
vey hitherto under your direction would allow. 
These articles are a portion of the series of ‘“ Contributions,” No. 1 of 
which appeared in the Annual Report for 1877, for which you had made 
provision among the publications of the Survey, in addition to the less 
elaborate ‘‘ Papers” and more exhaustive memoirs. While the cireum- 
stances referred to have rendered these articles less complete than could 
be desired, and less so than was originally intended, the illustration of 
nearly all ‘the fossil species that have been hitherto described in the 
publications of the Survey is an important point gained. 
Very respectfully, 
C. A. WHITE. 
Dr. F. V. HAYDEN, 
United States Geologist in Charge.
