Lozver Cretaceous of Kansas. — Gould. 15 
tion Beds from the Comanche to the Dakota Cretaceovis in 
Southwest Kansas."* 
The name Medicine beds was applied to the series. The 
Medicine beds consisted of four formations, "grading conform- 
ably from the marine Kiowa to the leaf-bearing Dakota. The 
type localities were on the head of the Medicine river in Kiawa 
county and on Upper Bear and Sand creeks in Clark county. 
The beds were defined on purely lithological grounds and 
were intended to be simply "a series of transition beds". 
During the summer of 1898 I was a member of the party 
of Dr. Ward and Dr. T. W. Stanton of the U. S. Geological 
Survey. We were accompanied by Mr. Mark White and a 
part of the time by professor R. B. Dunlevy of the Southwest 
Kansas college. During the summer the party visited all four 
localities discussed in this paper and made careful studies and 
collections at numerous points. 
The two localities of the Belvidere-Clark county region 
may be differentiated although they are in a sense connected 
and have many points of resemblance. Plate No. XLIV of 
Vol. II of the University Geological Survey of Kansas shows 
graphically the outcrops of the Cretaceous of the region. In 
the paper "On the Transition Beds etc." the following descrip- 
tion was given. "It (the Cretaceous) begins near Sun City in 
northwestern Barber county and gradually thickens westerly, 
attaining its maximum on the upper Medicme river west of 
Belvidere. It thins out tO' a mere line at Coldwater, again 
thickens on Blufif, Bear and Sand creeks in Clark county, and 
finally disappears at the Big Basin in the western part of the 
county."! Ii'' both localities the principal exposures are in 
valleys cut out by the streams from the Tertiary plain. The 
thickness of the Cretaceous near Coldwater was once probably 
as great as in either of the other localities but it has been 
removed by post-Cretaceous erosion and covered by Tertiar\- 
■or Pleistocene deposits. Exposures in this vicinity arc rare 
and when found are only a few feet in thickness." 
Belvidere, the village from which the localit}- is named, 
is a station on the Mulvane extension of the Atchison, Topeka
