SOME RECENT ASPECTS OF THE PERMIAN 
QUESTION IN AMERICA. 
By Charles R. Keyes, Socorro, New Mexico. 
After seeing at close range the "Red Beds" of New Mex- 
ico, I am convinced, that the Permian question in America is 
not to be settled on the basis of Kansas stratigraphy. Just as 
the Cretaceous of the Upper Missouri river region is not to be 
considered in terms of the Texas Cretaceous, so in Kansas the 
history of late Paleozoic times is far more complex and intri- 
cate than has been commonly supposed. 
Until within the past two years, accident of location threw 
me into closer association with the Kansas rocks than with 
any other of the American upper Paleozoic sections. My refer- 
ences to strata, which have been called Permian, have been 
chiefly taxonomie and nomenclatural in character. My com- 
parison of the Kansas beds, often called Permian, and the beds 
of the original Permian in Russia appeared to me conclusive 
on the point that the nomenclature and classification of the 
upper Paleozoic rocks of the United States are not advanced 
by retaining longer Murchison's title of Permian. 
In America, the Permian problem promises to be a much dis- 
cussed question. The Kansas beds often assigned this age have 
thus far come in for most consideration ; but the question is a far 
broader one. It is not at all likely that Kansas will ever af-
