56 KANSAS UNIVERSITY QUARTERLY. 
As will be seen, the centrum, while nearly the same size as that 
measured by Cope of C. col/ettii (second column), are of somewhat 
different proportions, but not sufficiently so to justify specific sep- 
aration. 
Associated with these remains are numerous teeth and spines of 
Pleuracanthus (Didymodus ?) and plates of a ganoid fish. 
Altogether we have here an interesting series of forms, so closely 
resembling the species described by Cope from Dansville, Illinois, 
that I cannot distinguish them specifically. It would seem to 
demonstrate the contemporaneity of the two formations, as also 
that of the Texas Permian, whence species of all these genera have 
been described by Cope. 
Above the stratum in which these bones are found are several 
hundred feet of limestone and shales, above which come the red 
beds of Clark and Comanche counties, which have been variously 
referred to the Permian and Trias. That this basal Permian fauna 
continued throughout all the time represented by eight hundred or 
a thousand feet of deposits does not seem probable to me, and I 
believe yet more strongly, what I always have believed, that the 
red beds of Kansas are Triassic in age. If they be Triassic, and 
corresponding to the red outcrops of the foot-hills in Colorado, it 
would seem strange that the intervening deposits between them 
and the Dakota, in the regions separated by only a few hundred 
miles, and agreeing in many lithological characters, should be in 
one case Cretaceous and in the other Jurassic.
