Another gull was Zarus oregonus, an extinct species new to 
science, which was about the size of Larus delawarensis, and its 
existence is based upon two humeri, both from the left side of two 
different individuals. The characters exhibited on the part of these 
bones are distinctly different from those of other gulls of this size. 
Anser condonit is a great extinct goose, vastly larger than our present 
existing Canada goose (B. canadensis). Its remains are represented 
in Professor Cope’s collection by a fractured os furcula and the parts 
of two others. These were carefully compared with the furculz of a 
number of our wild geese and swans of the genera Chen, Anser, 
Branta, Dendrocygna, and Olor, and it was found that, upon the 
whole, the majority of its characters agree best with Anser albifrons. 
These characters and comparisons are dwelt upon in detail in my 
forthcoming memoir. I have named this goose after Professor Thomas 
Condon, of the University of Oregon, the first naturalist who discovered 
and collected any of the remains of fossil birds in the Silver Lake 
region of Oregon, A fine series of bones represents the new brant, 
Branta propingua,—a small goose evidently referred to by Cope asa 
species that came ‘‘near nigricans.’ > I propose the above name for 
this now extinct form. 
One of the most interesting discoveries made in the Silver Lake 
region was the fossil remains of a new species of a now extinct 
flamingo, which I have called Phenicopterus copei, in honor of 
Professor E. D. Cope, who discovered it. I found a number of bones 
belonging to this species in the collection, and a study of them reveals 
the fact that P. copei was a somewhat taller and longer-winged flamingo 
than P. ruber, though at the same time it was probably not quite so stout 
in the body. 
A small heron, to which I have given the name of Ardea palocci- 
dentalis, and a new coot, Fulica minor, smaller than Fulica americana, 
were, as will be seen in the list given above, also among the novelties. 
The first-named was a species somewhat larger than 4. candidissima, 
and smaller than 4. egretta, with osteological characters identical with 
existing herons. Osteologically, too, the two coots agree, the species 
differing only in size. 
It will be observed that the Gallinze were very well represented in the 
avifauna of Western Oregon during the later Tertiary times, and among 
their fossil remains I found three species of them that proved to be new. 
Both of these were closely related to Pediocetes phasianellus colum- 
ianus. The larger form, Pediocætes lucasii, I have named in honor of 
my friend, Mr. F. A. Lucas, in recognition of his published labors in
