Prosspr.|  Ovetaceous.—Comanche Series of Kansas. 123 
west, is 885 feet. On the topographic sheet of the U. S. Geological 
Survey the difference in elevation for this section is 390 feet, which 
agrees very closely with the above. The section gives 220 feet for 
the upper Red-Beds, 52 feet for the Cheyenne sandstone and 113 
for the Kiowa shales, the top of the latter formation not being 
reached. The first outcrop of the Comanche seen on the bluffs west 
of the Medicine Lodge river caps a red butte, three and one half 
miles west of Sun City. This outcrop is somewhat farther east than 
the one reported by Professor Hill as four miles west of Sun City, 
A little farther west in an arroyo below the Comanche are red 
argillaceous shales in place, and on top, yellowish very sandy shales 
which belong in the Cheyenne formation. This exposure gives the 
contact between the red shales and Cheyenne sandstone. A little 
farther west at the side of another arroyo is an irregular line of 
contact between red shales and grayish sandstone, apparently a 
line of unconformability between the Cheyenne sandstone and sub- 
jacent Red-Beds. At their contact there are bright red ‘shales be- 
longing to the Red Bluff sandstone of Cragin, then one foot of white 
sandstone, and red shales again, upon which rests the Cheyenne 
sandstone the base of which consists of very white sand that be- 
comes more yellowish on top, and the exposure terminates in a 
covering of soil in which are large numbers of pebbles especially 
those similar in color to the Dakota sandstone. At the head of the 
Lanphier draw, on the eastern side of Stokes hill, where the black 
Kiowa shales are well exposed there is a dip of between 1 deg. and 
13 deg. S. 10 deg. W. In this draw the dip is quite marked, though 
its general amount is probably increased by a small fold. In the 
Ixiowa shales exposed around the eastern side of Stokes hill are 
somewhat coarse layers, as indicated in the section, which contain 
abundant fossils. From these shales many species were collected, 
as was also the case in Professor Hill’s work, and from his col- 
lection the following species were identified by Mr.’'f. W. Stanton: 
1. Gryphea forniculata White. 
Corbula crassicostata Cragin. 
Exogyra texana Roemer. 
Cardium mudgeti Cragin? 
Cardium bisolaris Cragin.
