344 Rh. W. Shufeldt—Eatinct Bird from South Carolina. 
Passing to the internal condyle, we find that it too is, upon lateral 
aspect, subcircular in outline, its postero-superior termination being 
produced upwards in a more or less prominent way, behind the 
above described independent excavation (Fig. 1). The intercondylar 
valley averages about 7°5mm. in width, being concave from side 
to side, and convex in the opposite direction. This fragment weighs 
23 0z., and has been marked with a red capital letter S on its 
anterior aspect immediately above the intercondylar valley. From 
this I am assured by Dr. Charles Schuchert, Curator of the 
Geological Department of the Peabody Museum of Yale University, © 
in his letter to me of February 25, 1916, that the specimen 
belongs to the ‘‘Scanlon Collection, and it has been loaned to 
Dg Jalen 
As to the formation from which this specimen came, I would say 
that Dr. Hay believed it to be Miocene, and this was also the opinion 
of Dr. Vaughan, of the U.S. Geological Survey, who likewise kindly 
examined it for me in February, 1916. It presents the general 
appearance of fossil bones of vertebrates from that horizon, and the 
question seems to be definitely settled by Dr. Earle Sloan, of 
Charleston, South Carolina, who says in his letter to Dr. Hay of 
February 29, 1916, in reference to these phosphatic fossils from the 
Stono River, South Carolina, near its source, whence the present 
specimen came, that ‘‘ Nearly all of the vertebrate fossils (many of 
the cetacea and squalidae excepted) are junior in origin to the 
phosphate bed, the cavernous interstices of which they entered with 
their associate supernatant ooze (described as Salkehatchie Ooze), 
which purely from stratigraphic relations I regard as of late Miocene - 
origin. 
“Tn this connection I beg leave to refer you to my Mineral 
Catalogue, pages 330 to 336. Also to page 472, which relates to the 
phosphatic ooze designated the Salkehatchie Ooze. 
‘‘'The Scanlon fossil collection was in the main taken from the 
rock dredged from the bed of the Stono River nearits source, or about - 
fifteen miles from the present coast line of the Atlantic, but coinci- 
dent with the old shore line of the Middle Miocene. 
‘The Mastodon teeth presented by me to the Museum were dredged 
from the bed of the Coosaw River, which represents the former wide 
estuarine area of several minor streams, most of which was sub- 
sequently covered by the Salkehatchie Ooze and subsequent sediments, 
marshes, etc. 
‘The Mio-Pliocene beds enclose many reworked rounded fragments 
of the senior phosphate bed, but have nowhere been observed under- 
lying Salkehatchie Ooze; therefore it is my opinion that the greater 
portion of the vertebrate remains in contact with the Old Miocene 
phosphate beds are late Miocene.” 
On February 6, 1916, at the U.S. National Museum, I compared 
this fragment of ‘the lower end of the right femur with the corre- 
sponding part of that bone belonging to birds of many groups existing 
in North America, and also with a number in my own collection of 
avian skeletons, as well as with certain fossil femora figured by me 
in my ‘ Review of the F ossil Fauna of the Desert Region of Oregon,
