FOSSIL FEATHERS AND UNDESCRIBED FOSSIL BIRDS 639 
feather, with the shaft and vane in excellent preservation.”? This 
specimen I have never seen, and I am unable, at the present writing, 
to say where it is deposited. 
Very fine, as well as large, fossil feathers of birds—and most 
perfectly preserved—are also found in various parts of Europe; 
one of these is here shown in Fig. 7, it having been photographically 
copied by me from Tab. I to a most valuable article on fossil birds, 
which appeared a year ago in the official publication of the K6nig- 
lich Ungarische Ornith. Centrale, a copy of which was kindly 
sent me by its author.” 
On the fourteenth of June, 1913, Dr. Charles Schuchert, curator 
of the Geological Department of the Peabody Museum of Natural 
History of Yale University, sent me for description a number of 
fossils, most of which were of birds and birds’ feathers, and all of 
the last two are utilized in the present article. 
Fig. 9 shows a large fossil feather that evidently belonged to 
a bird of considerable size. It is one of those sent by Dr. Schuchert, 
and was probably found at Green River, Wyo. (Cat. No. 1227). 
It is the distal extremity of the feather—about 65mm. of it— 
showing the shaft and the soft vanes on either side, the latter being 
sonfewhat disturbed proximally. This structure is of an extremely 
delicate character, and, if really a bird’s feather, it was of the

a large number of fossil birds from the region in question, most of them, if not all, 
being species still to be found in the avifauna of the Continent. 
3 Dr. Schuchert remarked in his letter of transmittal: 
We are sending you today by express, prepaid, a small box containing all of the fossil feathers that 
we have. On one of the slabs you will also notice two feet of a bird, and in another box there are quite 
a number of bird bones that were sent Professor Marsh many years ago by Professor Condon. You are 
at liberty to make use of these feathers in any way you see fit. Should you illustrate them or apply 
names to them, please place such information with the specimens, so that we may make the proper entries 
upon our records. 
The two fine specimens of Archaeopteryx I saw some years ago in Europe, and of course these are 
by all means the finest cases of preservation of bird feathers. There is at least one other occurrence of a 
bird feather from the Solenhofen Upper Jurassic, and I rather anticipate there might be more if you would 
make extensive inquiries in Europe, particularly in Munich. I have looked through Professor Marsh’s 
correspondence and find nothing there in the way of information concerning our specimens other than that 
given on the labels. 
Hoping you are well, I am, 
Yours truly,
