STRATIGRAPHICAL GEOLOGY 
not accompanied by illustrations; and at the time of their publi¬ 
cation a heated discussion over the so-called Permian beds of 
eastern Kansas was occupying the attention of American paleon¬ 
tologists, so that the discovery of the Guadalupe fossils passed 
almost unnoticed. Notwithstanding the fact that Dr. Shumard 
must be regarded as the actual discoverer of true Permian fossils 
in America it is to Dr. Girty that we are indebted for pointing out 
recently the real correlative significance of this novel fauna. 
Although Dr. Girty's memoir is mainly taken up with the de¬ 
scriptions of species, to many of which he applies new names, 
his observations on the stratigraphic relationships of the Guadalu- 
pan series are of great interest at this time, especially since they 
bear so critically upon the exact stratigraphic position of the so- 
called Kansas Permian — the Chase and Marion formations of 
Prosser, the Oklahoman series of other authors, and the Permo- 
Carboniferous section of some of the early writers. 
The position of the Guadalupan series is thus stated: If the 
Guadalupan fauna is Permian then the Kansas ‘Termian’^ is not, 
for they differ too greatly for both to belong in the same epoch; 
or, if it should prove they are in part contemporaneous, for the 
same name to be applied to them. At present I believe that the 
Guadalupan defined below by its oldest known fauna is younger 
than the Kansas “Permian” and that it belongs to a different 
epoch.”. . “It does not seem to me necessary to regard the 
Russian Permian as the last chapter in the Paleozoic history.” 
Dr. Girty’s elaborate comparison with the standard Russian sec¬ 
tion is particularly instructive, and illuminating; and seems fully 
to corroborate a similar parallelism made by others a decade ago 
after a careful examination of the original Permian province 
in company with Tschernychew, and other leading Russian 
geologists who had long worked in that field. 
Of far different character is the work recorded in the “Manzano 
Group of the Rio Grande Valley.” Although the author makes 
no mention of an already rather copious literature on the subject, 
that same literature sets forth even more fully than he does several 
of his principal conclusions, and of some of the remaining con¬ 
clusions presents unimpeachable evidence disproving their accuracy - 
long before they were published. 
When Mr. Lee states that “The name ‘Red Beds’ has been so 
constantly applied to these rocks that it has come to have more
